Signal manager

[Ярослав Лещинский]

Hi, everyone!

My battle with stm32 interrupts continues. Three month ago Andrei from The
Great White North gave me some code advise:

In my code I use interrupts for DMA with ADCs, and CAN using the HAL
> interrupt handler callback structure.
> In this case, DMA2_Stream2_IRQHandler calls HAL_DMA_IRQHandler in
> stm32f4xx_hal_dma.c which figures what caused the interrupt and calls the
> appropriate callback.
> In my ADC code I use this:
> rtems_status_code status;
> *const* *char* ADC1handlerName[] = "AD1r";
> status = *rtems_interrupt_handler_install*((rtems_vector_number)
> DMA2_Stream2_IRQn,
> ADC2handlerName, RTEMS_INTERRUPT_UNIQUE,
> (rtems_interrupt_handler) DMA2_Stream2_IRQHandler, NULL);
> *if* (status != *RTEMS_SUCCESSFUL*) {
> *printk*("interrupt handler install 2 failed with %d\n", status);
> }
>
> Later, I have the interrupt callbacks:
> *void* *HAL_ADC_ConvCpltCallback*(ADC_HandleTypeDef* hadc) {
> rtems_status_code status;
> status = *rtems_event_send*(ADCTaskId, RTEMS_EVENT_0);
> *if* (status != *RTEMS_SUCCESSFUL*) {
> *printk*("complete callback failed with %d", status);
> }
> }
> *void* *HAL_ADC_ConvHalfCpltCallback*(ADC_HandleTypeDef* hadc) {
> rtems_status_code status;
> status = *rtems_event_send*(ADCTaskId, RTEMS_EVENT_1);
> *if* (status != *RTEMS_SUCCESSFUL*) {
> *printk*("half complete callback failed with %d", status);
> }
> }



i was trying the same but only for EXTI driver and no result. I have such
code:
http://pastebin.com/BZBNPRbg

After flashing, i received in console string "53", when i pushed the button
- all stopped, only reset can brought him back to life.

In C user guide i didn't find any references to
 rtems_interrupt_handler_install, some info was
about rtems_interrupt_catch, but when i try to use this, i received
"undefined reference".

Maybe, someone can help me with that problem?

Thanks.

P.S. Sorry for my english.
