I'd like to expand a bit on this, because what i'm looking for is a rtos which provides true preemption, that is, no need for an endlessly looping task to...
With AvrX tasks have static priorities. If a high priority task becomes unblocked, it will pre-empt the lower priority task for the duration until it blocks...
Dear all, I use Timer Counter0 and Timer Counter1 in my program. I set Timer Counter0 for RTC and Timer Counter1 for timer routine. When finish executing...
You'll need to post the code before anyone can comment. You should cut your example down to the minimum code that illustrates the problem and then include...
Hi friends!! I have some troubles with the "get_char1(stderr)" function. I don't know why this function was working good before and without changing anything...
Hello friend! I have had connected a compass module to wrong pin. I don't know why but this was the problem that made non bloking of "get_char1(stderr)"...
The process ID is the address of the PID structure. Also, Suspend only works on running processes. If the process is blocked (not pre-empted) then it is...
Thank you very much Larry!! See you Larry Barello <yahoo@...> escribió: The process ID is the address of the PID structure. Also, Suspend only works...
I've got the latest AVR Studio, the latest WINAVR+GCC and the latest AVRX.. Now I'm trying to make them all work together... I installed WinAVR then studio and...
... I assume you're using a makefile, possibly just a modified version of the sample one that comes with WinAVR. In that case, just add in the appropriate asm...
Hello all !! I would like to know how much is the load of my microcontroller Atmega128's processor. Can it be done? or that it's impossible. I don't want to...
The way I measure load is to toggle an LED: Turn it off just before going to sleep (Idle Task) and turn it on at the start of each interrupt handler. Then I...
Thank you very much again Larry!! You are very kind. I will try the second choise, to calculate the load creating an Idle Task, it seems to be easier. :-) I...
Send as many as you like. The driver will buffer the first 32 bytes before blocking waiting for data to be sent out the USART. If you want to buffer more,...
I have recently started working on AvrX RTOS(v2.6f). I have successfully compiled avrx.a library for AT90CAN128 with few minor changes. But as I understand...
The special function registers for the UART are out of reach of the OUT/SBI/CBI instructions ("I/O Memory" section on page 24 in the AT90CAN128 datasheet)....
Thanks, UART registers reside in extended I/O memory and sbic instructions works only for first 32 register set only.. Hence I was getting the errors. But...
Hi all: It is working right now(as Below),but I do'nt know why? I need to add a delay loop after AvrXWriteEEProm before I write next byte , if not ,it will be ...
I don't know what avrx does in its EEPROM write subr0utine, but you could compare that code to this which does work (in bootloaders). It loops on a busy bit in...
Check the assembly code for AvrXWriteEEPROM. It should wait until the previous write has completed. The code is very old and the bits might have changed a...
I Check the assembly code for AvrXWriteEEPROM and pdf file of Mega128, the assemblly code is correct,But I try and try,if no delay loop,write EEPROM will be...
Hi! I am working with AT90CAN128 and gcc. I have some problems with AvrxBufferedSerial.c. The uart settings are all ok but when I send some chars to the serial...
Since AvrX is yet not proted for AT90CAN128, I am interested in knowing how can I use interrupt for CAN. avrx-signal.h inturn includes avr/signal.h which has...
The use of avrx-signal.h is very obsolete. If you are using avr-gcc you don't need any of the avrx supplied files. Those were created four or five years ago...
Mr Barello, First of all I would like to thank you for developing AvrX and making it available to all. Yeah, I got the basics of how it works...I really...
Hi, does anybody know an easy way to add a timeout to AvrXWaitMessageAck()? One option is of course polling with AvrXTestMessageAck() but i would like to have...
First of all I'll try to explain what I am intending to achieve. I am using AT90CAN128. In AT90CAN128 CAN, there are 15 Message Objects or MObs (In short...
Multiple tasks can wait on a semaphore. They queue up first come first served. When you signal the semaphore the first one will be released and the others...
Hello friends! I want to do a very simple thing, but I don't know how. I want to make a 750 us delay with AvrXDelay(&timer1, x ) but seems like with this...
