The Amazing 1 Microcontroller Jay Carlson. Silcon Labs EFM8 Fantastic value and ease of use from the only 8 bit part with a totally free cross platform vendor ecosystem. The EFM8 was the fastest 8 bit part in my round up, and admittedly, my favorite 8 bit architecture to develop with overall. What these parts lack in brains they make up for in brawns 1. ADCs, 1. 2 bit DACs, lots of timers, and a 7. MHz core clock speed that gives you timing options not found in any other part in the round up. Plus, this is the only 8 bit part with a totally free, cross platform, vendor provided ecosystem. Let that sink in. Keil C5. 1 is a silly compiler, but Silicon Labs does an excellent job hiding it under the hood even when running its Eclipse based Simplicity Studio on Linux or mac. OS. Simplicity Configurator is the lightest weight code generator in our round up, using only 5. DMX 5. 12 receiver project. It was one of the easiest to use, and seemed to strike a good balance between abstraction, performance, and ease of use. Debugging speeds are snappy with a J Link debugger, but at 3. Silicon Labs USB Debug Adapter is one of the cheapest first party debugger in the round up, and clones of the hardware are even cheaper. And call me old fashioned, but I think the 8. Microchip mega.

When we updated the footprint in Eagle to correct the naming on the schematic it. The Serial Peripheral Interface SPI is one of the popular embedded serial communications widely supported by many of todays chip manufacture and it. AVR 1 Series Different strokes for different folks still with the best 8 bit toolchain available. The mega. AVR came in surprisingly flat for me especially when compared with its lower cost, new sibling, the tiny. AVR 1 Series. Theres no comparison when it comes to price tiny. AVR has incredible value packing in a nice assortment of timers, analog peripherals including a DAC, and a new 2. MHz internal oscillator while costing 2. AVR. While the mega. AVR has a perplexing debugging experience that requires two completely different interfaces and protocols to work with the part, the new one wire UPDI interface the tiny. AVR sports worked flawlessly in my testing. But thats the crux of the problem for the tiny. AVR by shedding many of its mega. AVR roots, Microchip ended up with a wonderful microcontroller that will be challenging to use for a large base of Atmel fans indie developers and hobbyists who use low cost, open source programmers which dont support the UPDI interface. While the tiny. AVR wasnt the fastest part in the round up even among 8 bitters, it was the most efficient both in terms of active mode power and clock efficiency. Amazingly, the AVR only uses about twice as many instructions as 1. Unfortunately, the AVR system as a whole is not without its issues. The Windows only Atmel Studio is still buggy especially with older mega. AVR devices and AVR Dragon stuff in my tests, and there isnt an under 5. Xplained Mini dev boards. In many ways, there seems to be a tacit demarcation Atmel creates between its hobbyistindie developers, and the professional shops that use Atmel parts. As a professional embedded developer, I most definitely have access to Windows computers, and I have no problem blowing a few billable hours worth of pay on a 1. But even as popular as Atmel is among hobbyists, Atmel has largely stayed out of this space directly. Instead, theyve secured small volume AVR sales by relying on the open source community to build their own tools for themselves turning out a slew of hardware and software used to program the mega. AVR devices. While I applaud the efforts of these developers, these tools are inferior to Atmels. Their programming speeds are terrible, they dont support the new tiny. AVR 1 Series devices, and they have absolutely no debug capability. Having said that, both the mega. AVR and tiny. AVR have the best toolchain available for 8 bit MCU development. The part supports a full, end to end Makefile based GCC toolchain. If you love printf debugging, would never touch a proprietary toolchain, and hate IDEs, mega. AVR and old tiny. AVR parts are definitely for you. The older ones are still available in DIP packages, and as you probably know, there are a ton of low cost programmers available across the world. The online community is massive, and as clunky as I find Atmel START to be, I have to applaud its support for Makefile based project generation. Consequently, the mega. AVR remains the most open source 8 bit microcontroller on the market by a long shot. But Id really like to see Microchip provide a Pic. Kit priced debugger with UPDI support and allow off board debugging the way their PIC Curiosity Boards do. I also hope these open source projects can add UPDI support to their tools, so that hobbyists and indie developers can start integrating the tiny. AVR into their projects its a much better part, and if youre an AVR user with access to Atmel Studio, you really ought to buy an Xplained Mini board and take it for a spin. STM3. 2F0 A low cost, no nonsense part with arguably the best Arm development ecosystem tested. The STM3. 2F0 was the lowest power Arm microcontroller in the round up, and also one of the easiest to use. STM3. 2Cube. MX doesnt generate the most compact code on Arm that honor belongs to Cypress PSo. C Creator and Infineon DAVE, but it has a snappy interface, and the generated code is easy enough to manipulate for your own goals. I love the nearly stock Eclipse based environment that System Workbench for STM3. ST Link and excellent DiscoveryNucleo boards seals the deal for me. Most pros have used ST parts in their work, but for all these reasons, any hobbyist looking at moving to Arm should probably pick up a dev board from this ecosystem, too. ST has a huge market footprint, so theres tons of resources online aimed at both hobbyists and professionals. SAM D1. 0 Killer performance peripherals, but with runtime library hiccups. The MicrochipAtmel SAM D1. D1. 1D2. 0D2. 1 ecosystem has good value considering their analog portfolio includes a DAC, and they have good timing options, and the SAM D1. Professionals will like the easy to use, well documented header files, and hobbyists will appreciate the 1. SOIC package options and GCC compilers that come with the Arm ecosystem. But before I grab this part for a project, Microchip really needs to fix the extremely slow, bloated peripheral library, and update their code gen tool to do proper error checking of clock and peripheral configurations. As it is, whenever I use Atmel START on the D1. I want to STOP almost immediately. And there are no current, stand alone peripheral drivers that Microchip has released for this part, so unless you want to do register programming from scratch, youll be relying on third party, open source projects like Alex Taradovs code examples. Infineon XMC1. 10. Interesting peripheral perks make this Cortex M0 stand out. The most interesting Arm chip was, without a doubt, the Infineon XMC1. I think professionals who may be wary of getting out of the STNXPAtmel Arm ecosystem need to take a second look at these XMC1. XMC4. 00. 0 parts. The timer options are amazingly flexible, and you can squeeze fantastic performance out of the USIC module. Im going to go out on a limb and recommend that serious hobbyists who are building motor lighting control projects look into these parts, too. DAVE makes setting up these complex peripherals painless, and the 3. TSSOP chips will be substantially easier to solder than the 0. QFNs and QFPs you usually end up with in these pin counts. Introduction to Microchip PIC Assembler Language Part 2. With only 3. 5 instructions to learn the Microchip PIC microcontroller assembler language is considered very efficient and easy to learn you will not find such as Atmel AVR microcontroller CP compare and BRNE branch if not equal or BRGE branch if greater or equal on the PIC microcontroller assembler language dialect, instead its just provide us with a very simple bit test and skip one line instruction. This fact is what makes programming the PIC microcontroller assembler language become very interesting and challenging, therefore although is easy to learn but for sure you will need a lot of flying time in order to code the PIC microcontroller efficiently. The PIC Assembler Program Skeleton Continuing our lesson with the 8 bit, 8 pins midrange Microchip PIC1. F6. 83 microcontroller, I will start with the typical PIC microcontroller assembler program skeleton bellow The first part is the program comment its always a good practice to put a comment to your program e. All lines begin with sign is consider a comment to the MPASM Microchip PIC Assembler compiler. The second part is the include lt p. F6. 83. INC MPASM compiler directive which tell the compiler to include the PIC1. F6. 83. INC file definition which exist in the c Program FilesMicrochipMPASM Suite directory MPLAB IDE v. This include file contain the standard PIC microcontroller physical address to the equivalent naming convention for example instead of using the address 0x. IO, we could use GPIO which is easier to remember. Cod Mw3 Gun Sounds. The third part is the Microchip PIC microcontroller configuration bits register this register is start at address 2. PIC1. 2F6. 83 microcontroller and has 1. This register is one of the unique features of the PIC Microcontroller compared to other microcontroller, the PIC configuration bits could be configured on every startup of the program. The configuration bits register is used to set how the PIC microcontroller work such as choosing the internal or external clock, using the master clear or not, etc. When programmed these bits will be read as 0 for un programmed these bits will be read as 1. The following table shows the configuration bit used in our Hello World assembler program. The complete description of this configuration bit could be found at page 8. Microchip PIC1. 2F6. AND operator to the entire PIC MPASM configuration bit definition value we could configure the desire configuration bit register value or we could simply using just the bit value as shown on this following table Base on the configuration bit table shown above, we could set the PIC1. F6. 83 microcontroller configuration bit directly and this will give you the same result as the above program example config 0x. D4. The fourth part is the MPASM CBLOK 0x. ENDC directive which tell the MPASM compiler to map the Delay. Delay. 2 variables to the 8 bit general purpose registers which start at the address 0x. PIC1. 2F6. 83 microcontroller address BANK 0 the Delay. Delay. 2 will be mapped to the general purpose register at the address 0x. The following picture show all the Microchip PIC1. F6. 83 microcontroller registers address which split into 2 groups named BANK 0 and BANK 1. One of the unique things about the PIC microcontroller registers address comparing to other microcontroller that the address is not in one continues memory but its being split into two BANKS groups this mean we have to switch back and forth between the BANK addresses to access the desire register. For example if we want to access the register TRISIO, we have to switch to the BANK 1 before we could access it and switch back to the BANK 0 in order to access the GPIO register. To make it easier to understand you could consider the BANK 0 and BANK 1 are like the DIRECTORIES in your computer file system, so if you want to access the TRISIO register just like a file reside in your directory, you have to change the directory first to the BANK 1 before you could use this register and change directory back to the BANK 0 to access the GPIO register. If you notice some of the registers such as the STATUS register is shared or appeared to the both BANKS this mean it doesnt matter which BANK you are right now, you could always access this register. This is the same principal as the LINK file on the UNIXLinux operating system file system, that one physical file could appear on many directories using just the link name. The fifth part is the ORIGINATE org MPASM compiler directive that tell the MPASM compiler that your code is start at the address 0x. PIC microcontroller flash memory. The sixth part is where you put your PIC assembler program code this code could consist of main program and the subroutine or function. The last part is the end MPASM compiler directive that tell the MPASM compiler that your code is end here and its a good practice to put the EOF end of file comment mark in your program so whenever you cut and paste the program to the other project you could make sure that all the codes is being copied until the EOF mark. Inside the Hello. World Program. Now we will walk through the program codes, first thing I will explain the initialization routine to the PIC1. F6. 83 microcontroller in this initialization routine you will learn the top five of the 3. PIC1. 2F6. 83 microcontroller assembler instructions that you will certainly use in every project. Before we start make sure you have the PIC1. F6. 83 datasheet near you and open the page 1. Instruction Set Summary. Start. bsf STATUS,RP0 Select Registers at Bank 1. OSCCON Set the internal clock speed to 8 Mhz. TRISIO Set all General Purpose IO to output. ANSEL Make all ports as digital IO. STATUS,RP0 Back to Registers at Bank 0. The first thing in our initialization routine is to set the internal clock speed which can be controlled in the oscillator control register or OSCCON at BANK 1, we decide to run the PIC1. F6. 83 microcontroller with the maximum internal clock speed of 8 Mhz as shown on the OSCCON register bellow By making the internal oscillator selection bits IRCF21, IRCF11 and IRCF01 on the OSCCON register we select the 8 Mhz of internal oscillator frequency, this could be written as the following C program OSCCON 0x. But in the PIC assembler code, before we could use the OSCCON register we have to change to the BANK 1, since the default BANK when the PIC microcontroller power up is in the BANK 0 How to instruct the PIC microcontroller to change to the BANK 1 this could be done by setting the bank selection register bits RP1 and RP0 on the STATUS register. Because the PIC1. F6. 83 microcontroller only have two BANKS, then the RP1 bit is not use but for some PIC microcontroller families such as PIC1. F6. 90 or PIC1. 6F8. BANK addresses therefore for this PIC microcontroller families both RP1 and RP0 bits are used to select the BANK addresses. By setting the bit RP0 to logical 1 we instruct the PIC1. F6. 83 microcontroller to change to the BANK 1 and by clearing the bit RPO to logical 0, we instruct the PIC1. F6. 83 microcontroller to change back to the BANK 0 default. The famous PIC set and clear bit oriented file register operation could be used to achieve this task. Bit Set f Register Address 0x. F and b is the bit addressbcf f,b Bit Clear f Register Address 0x. F and b is the bit addressbsf STATUS,RP0 Select Registers at Bank 1.
