I have succssed with "make gcc" for kernel but get some error with Examples and TestCases, I'm using WinAVR20050214 + AVRX2.6e MCUCR = 1<<SE; ----> invalid...
You are attempting to assign a value to a constant/defined value; i.e. not a variable, not a memory location...etc. Try: outp(MCUCR, (1 << SE)); Cheers, ...
... Actually, outp is no longer valid in gcc-libc. It now uses direct assignment, as he used. You might want to check the manual for the latest version. ... If...
Thanks for your help, I think that it's not in avr-libc because it' compile success with no error when I used another example from www.avrfreaks.net with the...
I have fixed [Digest Number 400 error] by changing #define _SFR_ASM_COMPAT 1 to #define _SFR_ASM_COMPAT 0 in timers.c file :D but it generate the error such as...
WinAVR does not support the old "nordic" object file format, which is the error you are getting. You need to remove that target from the makefile and replace...
... I think you just want to upgrade WinAVR then to the latest version, which has all the new compailer, binutils, library, etc. I'm running on Linux so I...
Thank in advanced, but I don't know clearly about the makefile ... so Could you make an example for me or send me a new makefile with corrected this error ...
I just started using avrx, i.e. building timers.c and, trying to use the c-style assignment of i/o registers of course stumbled over _SFR_ASM_COMPAT being 1. ...
I'm sure someone has a solution for this common problem: My environment Windows XP WinAVR 20050214 AVRX makefile - I changed the pathname to be that of where I...
Hi. first thanks Larry Barell for AVRX. i used AVRX for a year and it satisfied all thing i needed. now i have some suggestion,please inform me about it. ...
... If this is specificly a uart function, I don't think it's as complicated as you are makeing it out to be. I've done this with simple blocking on a ...
hi!! i am a beginner and really have a very little knowledge of how rtos is designed. if there are any members in the group with the same state that i am in,...
Hi Shrikant, I am Pravin Meher from Pune. I also tried to learn avrx but I was not able to do so on my own. I found it difficult in getting started. I am...
hi pravin i am srikanth from b'lore. i have completed my B.E.(results awaited) in e&ce. i could understand very little about avrx. one good thing is that avr...
Dear Christopher. that's just simple example to explain case. how about access more complicated such TCP/IP FileSystem internal routines and .... it's easyer...
... Sorry, I've only done simple things. However, my advice stands -- try it the simple way. ========================================================== Chris...
Hi Shrikant, As I have told you I also dont have any experience in any RTOS. And I haven't worked on avr assembly. I have downloaded gccavr and avrx from net....
Dear Christopher. I adopted it, i plan to use other think. what about PICO ? ... __________________________________ Do you Yahoo!? Read only the mail you want...

I am not sure I understand this request. The shared function should have a parameter for the task specific item (be it mutex, timer, etc) If I understand,...
... Speaking of FSMs, you wouldn't happen to have done a i2c drier as an FSM in the interrupt handler ? My first stab a few years ago 'worked', but was ...
Actually, I think there is a reasonable way to simulate semaphores with timeouts. The technique takes advantage of the fact that timers are waiting on an...
Are you looking for a bit-bang driver, or something using the hardware? Anyway the answer is No for the AVR. However, I wrote an I2C driver using the hardware...
Here's what I wrote as an i2c driver. It supports bi-directional communications between i2c devices (in my case multiple mega16s). TWI is a little tricky on...
... Thank you ! This is what I was talking about. I took a stab about a year ago at converting Stephane Gauthier's I2C library to AVRX. The version I'm useing...
I really should have provided some kind of example. So here's a brief idea of how this works: // MASTER // you need this if you'll ever behave as a master. It...
Chris, Glad to hear it helps! And, sure, please send along any mods. There's no reason you can't split slave and master code, but then there isn't really that...
... Actually I could use an example of how you are passing the data: uint8_t twiMasterRead(uint8_t addr, uint8_t *data, uint8_t datalen) If I read this...
