Yeah, but can you take your modular ASM code and use it on an ARM processor, or an Intel, etc? This is one of the reasons why I like C, because I don't have to care which processor I'm running on. This is certainly not to say that all C code is portable, because it isn't, but I c

OK I think we need to split this discussion into 2 sections, those who are using an language for hobby and those who are using a language for work. The reason I say this is like a PCB layout program, hobbyists go for the package with all the included symbols and foot prints, wher

Thanks for all the replys. I have written a handful of programs for AVR and PIC in assembly. I find once you start to include LCDs (especially graphical ones) to the project the code gets quite large quite quickly. So my main reason in looking for a higher level compiler is for m

2004-03-15 by Mike Bronosky
It depends on your situation. If one of your major criteria is spending less time learning the language, less time writing the progam code, and your programs won't be too big, then BASCOM is probably your best choice. If you want to get a little more into it, C, using CodeVision

Assembly is great but in this day and age I would suggest learning C/C++. Some C/C++ compilers are very efficient at optimizing code. So much so, that in some cases, the compiler can optimize code better than even the most seasoned assembly programmer. This is primarily true with

For production use I still would recommend using an auto-switching power MUX. They rock. They will auto-sense the voltage differential and automatically switch between sources. Their cheap too. TI makes a few of them. Again, I'm using the tps2115. Here's the datasheet: http://foc
