I am working on STM32L051R8, which is set to use Stop mode, which wakes up on the start bit. I have a situation where the MCU wakes up on an unwanted start bit, and UART extracts unwanted data. The expected action is to ignore the unwanted data and e...
Hi,I have built a handful of STM32 designs before and never had a chip fail to connect. I can't seem to get any connection in Cube Programmer at all:VDD,VREF+,VBAT is at 3.3V, VSS is connected to ground.NRST is high at bootI can see current drop fro...
Hi,I am currently using f446 nucleo board with some over uart interface.I am able to send the desired frames over Uart to sensor and sensor is properly responding by sending positive acknowledgement to each uart sent frames.And this verified in logi...
Missing STM32U0 series in table 3 of AN4894 - How to use EEPROM emulation on STM32 MCUs and STM32U3 series is duplicated.
im looking through the STM324x9I_EVAL files and in the stm324x9i_eval.h there is a MACRO "WAKEUP_BUTTON_EXTI_PORT_SOURCE" thats defined as EXTI_PortSourceGPIOA. im wondering where is this defined i cant seem to find the anywhere

I'm following along AN6000 to bypass the internal SMPS of the STM32N6 and use my own SMPS and LDOs power several of the power rails for the MCU and have some questions:1. In section 3.2 "System power/up/uncontrolled power-down sequence", the document...
Hi community,here my minimal code example: int main(void) { HAL_Init(); SystemClock_Config(); FLASH_EraseInitTypeDef s_eraseinit = {0}; uint32_t pe = 0; s_eraseinit.TypeErase = FLASH_TYPEERASE_PAGES; s_eraseinit.NbPages = 1; ...
I need to save a couple of bytes (a settings struct) to upper (last) page of the Bank1 flash. The settings are changed very rarely so lifetime of the flash is not an issue. The settings struct has a CSC member so when the settings are read from the f...
