STMCubeMX + STM32F0308-DISCO + RTC Alarm

Hello,

I am using STM32CubeMX with F0_V1.4.0 HAL to generate a IAR 7.40 EWARM project.

I have setup the STM32F030R8Tx CPU to use the RTC, and generate an internal Alarm A.

In the STM32CubeMX I have setup the RTC configuration parameters to have the time set to 01:01:00 and the alarm time set to 01:01:10. In the NVIC Settings I enable to RTC global interrupt through the EXTI lines 17, 19 and 20. I then generate the project.

It runs through and initialized the RTC, and sets the alarm in the MX_RTC_Init(); function.

I set my debugger to run to inside the RTC_IRQHandler() function, but it never gets there.

Has anyone successfully used STM32CubeMX to setup an RTC alarm interrupt? I can use the

STM32Cube_FW_F0_V1.4.0\Projects\STM32F0308-Discovery\Examples\RTC\RTC_Alarm

to get the RTC to interrupt, but even if I copy and paste the settings of the example to the cube generated version. The alarm never goes off.

Thanks for any help.

Hi mike.s,

Could you please share the .ioc file you used to generate your code?

I need it to compare the CubeMX generated code with the one available in the Cube package.
