Working with the RTC I'm having some issue with the callback only being called a single time. void HAL_RTC_AlarmAEventCallback(RTC_HandleTypeDef *hrtc) { RTC_AlarmTypeDef sAlarm; uint32_t hobb_time; __HAL_RTC_ALARM_CLEAR_FLAG(hrtc, RTC_FLAG_AL...
This might be a really stupid question but I recently downloaded RM0090 revision.19 for reference in use of timers in STM32F407IGT6.But I have noticed some diffrences from old reference manual & I can't find revision history for that. Old revision of...
Posted on July 12, 2017 at 21:23Hi,For the STM32F7xx family, the UART HAL library includes in its public API the function UART_SetConfig(), by which certain UART parameters can be modified at run-time, after the initial configuration (baud rate, par...
Posted on January 09, 2015 at 16:49Hi I'm a newbie to stm32 , I have a STM32F4 Discovery board with me. So what I want to do is to generate 2Mhz,4Mhz,8Mhz square wave on any of the Pins on the Header. Can you please provide some sample code for th...
I'm using an STM32H725ZE chip. I know that PA15 defaults to JTAG pin JTDI, but the datasheet for the part specifically says this:In SW-DP mode, the unused JTAG lines JTDI, JTDO and nJTRST can be used for otherfunctions.I'm in SWD mode because it's a ...
Hi I am programming a STM32L433 and have the processor wakeup from Standby mode. The first thing it does after wakeup is check the cause of the wakeup, and if RTC increase the time, do a few readings and go back into Standby mode. When I am running ...
Posted on May 03, 2016 at 00:19I have a digital input GPIO line where I need an interrupt whenever its input changes. In STM32CubeMX I set this pin to an EXTI line and set the interrupt to trigger on both rising and falling edges. When, in response ...
Hi,I want ot use the UART bootloader to program a STM32G070RB (with the Nucleo board). I've used the following code to activate the pin Boot0 to access the bootloader (some of it may be useless):while(FLASH -> SR & FLASH_SR_BSY1); FLASH->KEYR = KEY1;...
In LPLTIM_IER register, the ARRMIE bit is SET by software and LPTIM_ISR register the bit ARRM bit is SET by hardware but this LPTIM4_IRQHandler() function is not calling. what might be the reason of not calling this function LPTIM4_IRQHandler() ?
Hello ,I recently bought the STWIN.box core system board (STEVAL-STWBXCS1), so I don't know everything about it. I would like to carry out a predictive maintenance project. I followed the steps below:1- flash the binary file with STM32CubeProgrammer2...
