hi, I use the official example to change, the example need two board(one master and one slave), I am tring to make spi master and slave communication in one board, My board stm32f411ve. I use PortB13~15(spi2) and3~5(spi3), when I set both of spi2 and...
Using the STM32F769I-DISC1 evaluation board I am trying to use SAI1 to output a TDM audio stream. I know the CODEC doesn't support that format but my production board will need it.When configured as master transmitter, I get good SCLK, data and fram...
I am working with the STM32F446 microcontroller and I want embed the option bytes into my source code so I wrote the following and call it first thing in main():static FLASH_OBProgramInitTypeDef __attribute__((aligned(4))) CORRECT_OPTION_BYTES = { ...
I am trying to receive variable length of data by manipulating the the RxXferCount value and pRxBUffPtr.I am getting desired results most of the time but for certain time the receive buffer is unable to capture all the bytes i sent.I tried to debug i...
I am trying to establish I2C communication between 2 STMs. The master is NUCLEO-L432KC and the slave is NUCLEO-L412KB. I changed the address of slave in cubeMX to 0x01 which is in the 7-bit address format. But I am not able to send or receive data. ...
I can't get the sample running on my stm32F746-discovery. I followed the instructions in https://www.youtube.com/watch?v=43qQhrXc3n4.After changing MX_QUADSPI_Init(void) to the values inthe stm32746g_discovery_qspi.c I get a picture with a button but...
Hi,I am currently facing an issue on a STM32F469NI MCU where the HAL_FLASH_PROGRAM() is succeeding yet fails to write to the flash memory.I have verified this with a basic project for the STM32F469Discovery to isolate hardware. It appears that after ...
Dear community,I've been playing with the STM32L4R9I-Eval board and it seems that I can't drive the PG9 pin.My plan is to use the UART1 with the following pins:PB7 (rx) PG9 (tx).I checked the documentation and to use PG9 you have to:Remove R236Open S...
Hi,I am facing an odd situation when I use HAL_Delay. In most of the functions I have it works well, but in some functions the program stays in this loop forever:while((HAL_GetTick() - tickstart) < wait) {}When I debug, the difference between two val...
