Hello, I am a newbie of Avrx. Recently I am working on ATmega8 and trying to let Avrx run on it. But I failed. Who can give me some hints about Avrx on...
Hi, Wenmin ... Hmm, it's difficult to give you any hint when you don't tell what you've tried and where and what failed... Error messages, Effects, Debug...

Hello! My experience with porting AvrX to ATMega8 is as fallow: - it works fine with timers, messages, serialio, - simulation in AVR Studio environment fails....

Hello, I made a avrx library(avrx.a) from the avrx 3.6e for ATmega16 package. then I got avrx.a file. but I can't use it at AVRstudio. I compiled avrx.a with...

This isn't an RTOS problem. There are many ways to do what you want to do. The simplest would be a routine that sets a pin high, spins for a variable amount...
I plan to expand the Fifo routines to accomodate arrays such that I can for example effectively have a buffer of CAN data packets. In reading the Fifo code, I...
Hi, ... The compiler doesn't do bounds checking. As long as the buffer is allocated large enough, then everything works. More recent versions of the compiler...
... I would say you (the OP, sorry I'm replying to the later message) are correct -- the buf[1] is wrong. Where did this come from ? This looks close to...
It comes from the 2.6g AVRX release from the files area. Actually, speaking of the BuffSerial routines, I noticed that there is a context switch for each byte...
... Take a look at it again, I don't think it does a context switch for each byte sent (or received for that matter). It is setting the semiphore for each byte...
From the interrupt routine, there is a Prolog/Epilog section around sending one byte: ...but I could be missing something....maybe if the interrupt gets...

Prolog and epilog are safe with regard to re-entering. You are right, however, if the interrupt rate is greater than what can be processed, the kernel stack...
I haven't counted the cycles for a long time, but switching from task to kernel is about 150 cycles and switching back to a task is around 100 cycles. It is...

There isn't much to post. Just take Epilog/Prologue and insert a few lines of assembly to disable/enable the AvrX interrupts (those you assign) instead of a...
