STM32H757: Trying to read ID (Command 0x9F) HAL_QSPI_Receive locks up.

I'm starting super simple - Just reading the Manufacturer ID. Using a Cypress S25FL256L Flash. My test program:--------void QSPI_TestTask (void * pvParameters){  QSPI_CommandTypeDef sCommand;  uint32_t      MyID = 0;  /* Initialize QuadSPI ----------...

I get stuck in an interrupt after calling SPI transmit.

Hi!I have STM32F373VBTx and I have set pin PD3 as EXTI3 where PD3 call this function when the PD3 gets a falling edge. PD3 is labeled as TS_IRQ in STM32CubeIDE 1.6.1/* Callbacks for external interrupt */ void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)...

I have no idea which framework to use. You have too many. Which one will meet my requirements? (listed in details)

I want to code in C++, at least std=C++14, preferably C++17 or better.I do not want any drag and drop stuff. Nothing.I do not want to be forced to use code generators.I want a framework that other people actually use and write code for.I want a frame...

CANBUS peripheral of the STM32F746ZG works with a MCP2551 transceiver..??

Hello, I have a big doubt. I have a STM32F746Z microcontroller and I want to use the CANBUS peripheral connected to a MCP2551. The MCP2551 datasheet specifies that the communication lines with the microcontroller work with 5V voltages and the STM32F7...
