app_timer.h bug?

[gk117542]

Hello,

I encountered a compilation issue when using the app_timer function. The error message is: "'TickType_t' undeclared (first use in this function)". I believe the problem is related to some incorrect configuration in FreeRTOS, specifically with the  #define configTICK_RATE_HZ ((TickType_t)1000), but I'm unsure how to modify it.

I would appreciate it if you could assist in analyzing the issue.

Thank you in advance for your help!

Best regards,

Hi,

From  How to use libuarte+app_timer on FreeRTOS :

"you need to remove app_timer.c from your project and add app_timer_freertos.c so that the app_timer API is available to your application. App_timer_freeertos.c still uses Freertos timer API so it should work ok."

Try that.

Thanks,

I think my project is correct, there is no app_timer.c in it, only app_timer_freertos.c, the error here is mainly because APP_TIMER_TICKS (MS) is used, if I use a tick value is correct, but I now need to convert ms to tick.

#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

the macro definition FREERTOS is defined.
