ChibiOS Free Embedded RTOS

Hi,

I want to Know if Chibios has one shot timers or not?
if not, can I make one shot timer by making the timer call back function disable the timer or this is not allowed? and how can I make one shot timer?

thanks

I figured it.

the problem was in IAR IO header file, it defines the timer 0 int. vector location as

#define TIMER0_COMP_vect (0x28)

the extra parentheses"()" was the problem, so I redefined it in my board.c file like this

#define TIMER0_COMP_vector 0x28

and it works fine, thanks for your ...

hi,

here is the example of timer0 compare interrupt.

#pragma vector = TIMER0_COMP_vect
__interrupt void TIMER0_COMP_vect_ISR(void)
{

CH_IRQ_PROLOGUE();

chSysLockFromIsr();
chSysTimerHandlerI();
chSysUnlockFromIsr();

CH_IRQ_EPILOGUE();
}


and here is the Macro I made but the compiler ...

what is tickless kernel? can RTOS work without tick interrupt ?

Make 3.0 32bits only and optimize for it. NilRTOS could be targeted to the 8/16 bits space and be able to use the new HAL

I am afraid this could be a step that lead to drop 8/16 bits support, and what is NilRTOS ?

also can I ...

Hi Mr Giovani,

thank you too much as your answers helped me to finish the context switch on IAR AVR although it was very tricky as it took me 3 days because IAR AVR uses two stacks Cstack and Rstack.

when I try to include the HAL, the code does not compile, is the HAl Generic or it depend on AVR ...

thank you Mr. Giovanni for answering my questions.

kindly I need more information.

I noticed that Chibios is different than other RTOS by providing two ways for context switching, one from interrupt and other by calling OS APIs like chThdSleep , this way makes chibios faster in context switching ...

I don't want to start a thread about GCC but lets say that I have bad experience with GCC, with all my respects to it, but GCC behave strangely when optimization -os is used, look at http://forums.adafruit.com/viewtopic.php?f=11&t=4343 as a small example,I also faced many of these ...

Hi,

I need to have port for IAR compiler for AVR micros, if any one has a port, kindly share it with me.

is there any plans from ChibiOS development team to make one?

if there is no port, I will make one.

I need to know the usage of function _port_thread_start as I found it defined in every port ...

HI,

I read on the supported architecture and devices that Chibios supports ARM Cortex-m0 architecture on device LPC11xx.
I am working on a project and I will use LPC11U24FBD64 which is one of LPC11U2x microcontrollers from NXP which is also Cortex-m0 device.

Kindly tell me will chibios support ...
