Serial Driver Input for Events Error

[erwinkendo]

Hello Giovany and other forum members

Today I come here because I used event for SERIAL Driver input a long time and now with the new functions I was testing its functionality as seen in this post: http://forum.chibios.org/phpbb/viewtopic.php?f=2&t=872.

This method is working fine in my custom board with ARM Cortex M3 STM32F0 using SD3 (USART3), but when I use it in SD5 (UART5) this method doesn't work.

Configuration for both drivers.

Code: Select all

static SerialConfig SERIALtestcfg = {
  57600,
  0,
  USART_CR2_STOP1_BITS | USART_CR2_LINEN,
  0
};

Code: Select all

static WORKING_AREA(myThreadWorkingArea, 128);
 

__attribute__((noreturn))
static msg_t myThread(void *arg) {
  (void)arg;
  chRegSetThreadName("radio");
  EventListener elRadio;
  chEvtRegisterMask((EventSource *)chnGetEventSource(&SD5), &elRadio, 1);
  while (TRUE) {
    flagsmask_t flags;
    chEvtWaitOne(1);

    chSysLock();
    flags = chEvtGetAndClearFlagsI(&elRadio);
    chSysUnlock();
    chprintf((BaseSequentialStream *)&SD3, "Flags %d\r\n", 
       (uint16_t)flags);
    if (flags & CHN_INPUT_AVAILABLE) {
      palTogglePad(GPIOD, GPIOD_LED);
      int32_t c = 0;
      while (c != Q_TIMEOUT) {
   c = chnGetTimeout(&SD5, TIME_IMMEDIATE);
      }
    }
}

When there is input in SD3, the flag is

Code: Select all

CHN_INPUT_AVAILABLE

, but SD5 doesn't outputs any flags with the same code that works in SD3.

Any help regarding this?

Thanks

Hi,

All the drivers use a shared code for generating event flags, I can't find any reason for SD5 to not work exactly like SD3. Are you sure everything else is equal?

All code working now in all the UART devices. Checked several times, as it is usual, some pin confusion.

This events information is very usefull but it was really a pain to find it, it would be nice to have an example like this documented somewhere else, but for the mean time this will do.

Thanks
