Hi,I am working on STM32 MCU, in my application once I start IWDG, based on certain event I want to freeze IWDG.Since my application is running, I don't want to reboot MCU.Once event processed, I want to continue IWDG without resetting MCU.Can anyone...
I am trying to use the bootloader of the STM32G474QET6 with USART to program my microcontroller. I have multiple questions regarding this but the first one is more about hardware. I have found in AN2606 that for the bootloader I can only use one of t...
Hi Everyone,I interfaced Nucleo F767ZI with W25Q256JV using SPI and everything was working fine. But due to time and speed requirements, now I have to shift it to QSPI. I have used example code of STM Document named "QSPI_F769_discovery_flashloader" ...
Hi all,I'd just like to report an error on the reference manual for RMSTM32F411 (RM 0383 Rev 3).The error is located on page 471, on section RTC Register Map.The table showcase all registers for the RCC and miss the entry for RTC_SHIFTR (located at a...
Hello, ST experts The temperature sensor in STM32U595 is used for a mesurement. As datasheet said TS_CAL1 can be read at address 0x0BFA0710~0x0BFA0711. But this value is for 3.0V VREF, how is the situation if VREF and VDDA is 3.3V? How can I get the ...
Hi.In AN5593, How to use the GPDMA for STM32 MCUs, on page 31, it says:"For some application needs, a timer request to GPDMA can be used to initiate a data transfer not involving timerregisters read/write, but other memory-mapped location, like for m...
I am starting to experiment with stm32f411vet6 (discovery), I have passion for STM32, looking forward to learn and help.When I turn on UART 6 and test, the default pins are PA9 and PA10, however it doesn't work (some error characters like question ma...
Hello, I'm trying to measure cyclic temperature on a dedicated task with FreeRTOS. For that, I set my ADC with DMA, based on the example provided here (at DMA section: https://wiki.st.com/stm32mcu/wiki/Getting_started_with_ADC#Configure_DMA) For ...
I can't get TIM15 or TIM17 to work on a Nucleo-F302R8 board. If I examine the peripheral memory where TIM15 (0x40014000) and TIM17 (0x40014800) should be, I always read back all zeros.For example, using gdb I write to the timer's ARR register and the...
Hi,I am using the continuous mode of the ADC to continuously sample a channel and transfer the data by DMA. I have set the ADC frequency to 32 Mhz , and the sampling CLK to 3.5 CLK. According to the manual , the whole sampling conversion time should ...
