I could locate the HAL_NVIC_SetPriority() calls for DMA and EXT1 Interrupts in main.c as shown below.I could not find the HAL_NVIC_SetPriority() calls for RTC, USART & Timers - TIM4, TIM5, TIM6, TIM7. Where is the interrupt priority for these periph...

The work-around is mentioned somewhere in this post. I will repeat here:You must create a dummy global variable in your project and add it to the "Live Expressions". When you see junk values in some/all the variables, then write some value ( say 0 or...

Adding to the steps by FMadi.1 (Community Member)(1) go to and open the workspace folder(2) locate the project folder you wish to duplicate. Do a Project->Cleancopy it, paste it, and rename it (to ***, for instance)(3) open the *** project folder, lo...

I finally received the CL=6pF Crystals and paired them with 6pF NP0 capacitors on the next lot of boards.Very small drift of around -0.5s max per day was observed. Thanks again for the help received on the many settings to get the RTC working correct...

Thanks, the HAL_NVIC_SetPriority() calls are added to the stm32f1xx_hal_msp.c file in the HAL_<Peripheral>_MspInit() functions

For interrupt priorities set using the STM32IDE CubeMX, where are the auto-code generated HAL_NVIC_SetPriority() calls located?

STM32F405RG's RTC time drifts by +/- 6s per day (compared to UTC)

STM32F030C8 GPIO Max Source Current is limited to <5mA
