FreeRTOS app_timer.h bug?

[william.ely]

I'm using FreeRTOS and trying to get push button events to fire. The events would fire if I held the button down long enough. I found out that the problem was that "FREERTOS" wasn't defined anywhere so the APP_TIMER_TICKS macro wasn't calculating the right value.

/**@brief Convert milliseconds to timer ticks.
 *
 * This macro uses 64-bit integer arithmetic, but as long as the macro parameters are
 *       constants (i.e. defines), the computation will be done by the preprocessor.
 *
 * @param[in]  MS          Milliseconds.
 *
 * @return     Number of timer ticks.
 */
#ifndef FREERTOS
#define APP_TIMER_TICKS(MS)                                \
            ((uint32_t)ROUNDED_DIV(                        \
            (MS) * (uint64_t)APP_TIMER_CLOCK_FREQ,         \
            1000 * (APP_TIMER_CONFIG_RTC_FREQUENCY + 1)))
#else
#include "FreeRTOSConfig.h"
#define APP_TIMER_TICKS(MS) (uint32_t)ROUNDED_DIV((MS)*configTICK_RATE_HZ,1000)
#endif

Hello,

 

Are you using one of our FreeRTOS examples, or did you start from scratch with one of the template projects?

 

If you look in our FreeRTOS examples in the SDK, "FREERTOS" is defined in the preprocessor defines, in the project settings.

Try to define "FREERTOS" there, and see if it behaves more like you would expect after that.

 

Best regards,

Edvin

It works as expected when I define FREERTOS. I wish the SDK configuration process was simpler and that it was easier to migrate a demo into a real project. So far the hardest part of developing for this chip is making sure that I have the SDK configured in a way that is compatible with the demos I have adapted into my project.
