Hi,I have two B-L475E-IOT01A boards and I am testing the SubGHz P2P application available in the STM32CubeL4 package. Whenever I press the User Button on one board the led LD1 on the other board blinks, and as the ACK command is received the led LD1 ...
I want to calculate the measurement accuracy.
I'm using the STM32F0 Discovery (STM32F051R8T6) and trying to measure temperature via an ADC input. We're using the formula: VChannel = (3.3V * VREFINT_CAL * ADC_DATA) / (VREFINT_DATA * fullscale), but we are unsure what to use as the VREFINT_DATA va...
Sorry to be asking so many questions, but these dual core h7s are hella complicated and the documentation can be a little vague.I am trying to understand how to set up the dmas to work with the mdma. I think i get the dmamux and how the mdma works wi...
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...
