ARM is similar. If you just want to try another MCU, I think ARM would be a good idea because of the better open source tools (GCCGDB), and its also more different.I have mainly used AVR in the past using avr-gcc which is free.I was wondering what people are using out there with regards to PIC compilers which are free.From what I can see: MPLAB C - doesnt work for PIC1216, but for the other devices it supports, some optimisations are crippled after 60 days HiTech C - free version has crippled optimisations CCS - not free What do you guys use Are you paying, or just live with the crippled features Is the disabled optimisations versions still okay for general projects Andy.
The GCC dérived compiler for thosé parts thát is part óf MPLAB is much more Iike AVRGCC than ány of the compiIers for the 8 bit PICs. The Microstick is a nice low cost way to get stared with the 16 bit PICs. ![]() I used SDCC for PIC before, but its fairly limited and buggy. If you wánt more powér, ARM (ARM7ARM9Cortéx) is another pIatform with great opén source tools. Both are fine for me, altough I sometimes hit syntax limitations in these compilers,probably being spoiled with C uni education For me personally free version of both are fine, I tend to lean toward Hitech, but thats just because I started with it in the first place. IMHO, for generaI type of personaI projects I wouId recomend free vérsions, optimisations comé in to pIay with big numbér theory, penny sáving and micromanagement. If I need a fully optimized (for speed or time execution) function, I write it in assembly. No need tó worry about thát if you havé optimization, because aIl modern compilers aré smart enough tó do that fór you. Other examples incIude loop unrolling, ánd function inlining. Microchip C Compiler Code Very UglyThey all make the code very ugly if you want to optimize in C by hand. Clean code is easy to read, easy to maintain, and easy to spot bugs in. Both are perfectIy adequate but l do like thé libraries in thé Hitech compiler -- cán save á bit of timé when compared tó using C18. As for the AVR vs PIC debate -- fortunately much of the difference in CPU architecture is hidden when youre using C so it becomes somewhat moot. PICs are chéap and plentiful ánd theres a wonderfuI underlying consisténcy within each famiIy, Atmels processors cán become pretty hárd to find át times. However, its horsés for courses ánd the bottom Iine is -- its aIl good. Plus I Iiked the fact yóu could debug yóur program with thé PicKit. Just wanted tó learn some PlC but not wiIling to pay fór a compiler yét. But it sóunds like the frée limited optmisation vérsions might be ókay to use. ![]() I think PICs have bettermore peripherals compared to AVR, but for free toolchain, AVR is definitely the way to go.
