My favorite C compiler for Atmel AVRs is CodeVisionAVR. One of the big things I like about CV is the CodeWizard. You can DL and checkout the evaluation version at http://www.hpinfotech.ro/html/download.htm To me the big draw to WinAVR is that it is free. The time spent using it i

A vote here for Imagecraft http://www.imagecraft.com/software/. Very cheap and reliable C compiler. They also have a great email group where the compiler writer is a regular reader and contributor so they are very responsive. Dave Pallant AVR-Chat@yahoogroups.com wrote on 12/08/2

Right now, I'm using AVR Studio 4 (assembly) to program my AVRs. I know C/C++, so I think I might try some C coding for AVRs. It looks relatively easy, and it seems more and more people are using it. Which C compiler (cheap/free) would you all recommend?

I was able to fix my butterfly then replicate the problem. Gents, if your butterfly gives you the verification error and wont program via the bootloader, it is because your butterfly was shipped with locks on the application section of the flashrom. I had to hook my butterfly up

Im using Atmega8 in my projects, and I have a question about, what to do with pins not used? in the case of AREF I read that I must conect to Vcc by a resistor, but in the other pins dont know what to do. Thanks in advance.

The STK501 top module has a 64 pin socket not a 44 pin. Owen. Not sure how many is a lot, but..... If you already have a stk500 perhaps a stk501? Not the cheapest, but maybe the simplest. Then you also have the stk501 around for development. ISP can be handier if you have the roo

Sounds like you need the volatile modifier in front of you variable declaration Ie volatile uint8_t msCount; This tells the compiler that is the variable is modified outside of the interrupt routine. -----Original Message----- From: AVR-Chat@yahoogroups.com [mailto:AVR-Chat@yahoo

What about the FT2232 chip that has JTAG-like output? Not used it myself, but it looks sort of OK for what you're doing. However, 100MHz TCK is very optimistic for a software-only solution or even a hardware solution using the FT2232. You might want to look at the Cypress devices

And if you want one with the east of self-programming via a download from the serial port rather than the in-circuit-programming cable. Not all AVRs can be serial-port programmed (aka bootloader) -----Original Message----- From: AVR-Chat@yahoogroups.com [mailto:AVR-Chat@yahoogrou
