Resolved! Read data in multiple GPIOx_IDR register / Combine GPIO Ports
HiI'm currently using STM32H743 and I'm trying to Read Data in multiple GPIOx_IDR registerPreviously, I was using 16 bits and trying to change into 32 bits for IDR.When I debug, I could find correct data on SFRs -> Register -> GPIOA -> GPIO_IDR with ...
GPIO retention method
Is there a way to prevent the GPIO from changing even if a Self reset is executed?void SelfReset_Handler(void){ WWDG_SetPrescaler(WWDG_Prescaler_8); WWDG_SetWindowValue(80); WWDG_Enable(127);}Mcu Self Reset -> GPIO High retention

UART DMA RECEIVE ON STM32H755ZI DUAL-CORE MCU
Hi,Recently I bought a STM32H755ZI Development Board and would like to use it for UART RX with DMA. I used CubeMX to generate the project and everything worked fine with the function "UART_RECEIVE_IT()" but never worked with UART_RECEIVE_DMA(). I've ...
Resolved! I have pruchased a STM32L476VG Discovery board recently. I wanted to build a USB to CAN Interface. For that purpose I need to take CAN Tx, Rx data lines from the STM32 Discovery board and I have to connect those lines to any external transceiver.
I had gone through the datasheet and user manual. I could not fined respective CAN_TX, CAN_RX pins on the board(Pin Number PA12(CAN_TX), PA11(CAN_RX)). These pins are not available on the Discovery board. Then how can I take CAN TX, RX data to the ex...
