SPI EOT interrupt triggered right after SPI enable

Hello,I do some SPI communication, which in general works fine, now I want to get an interrupt at the end of transmission. I use only TxFifo, so TSIZE is left 0. It works fine to load some data into TxFifo via TXDR. Now I enabled SPI interrupt and se...

[Worked around it] SPI Transfer half complete Not working corectly

I have setup the spi connection, and i'm testing it with a logic analyzer.It all works great. BUT, the Transfer half complete interrupts occurs before any data is transferred when i use;(HAL_SPI_TransmitReceive_DMA(&SpiHandle, (uint8_t*)aTxBuffer, (u...

Im working on stm32f103 controller which has an eeprom interfaced to it via spi.

For the spi mode CPOL = 1 and CPHA =1 does the master(stm32f103 controller)​ receives data on MISO line at the rising edge and also sends data on the MOSI line at the rising edge? Similarly for the spi mode CPOL =0 and CPHA = 0 does same happen as fo...

How to put device into shutdown mode? STM32L4R5ZI

I am trying to modify the example given for neucleo - LP14R5ZI and port for my custom board.User button in example is similar to PA0 in my codeand similarly for LEDThe device does not go into shutdown mode. I have attached main.c of my modified code

I want to write and read data to internal flash. How can I do this. I am using STM32F103C8T6 mcu. Give some examples please.

Interruption on an input capture mode timer

Any example or link to STM32F4 Discovery for ranging an ultrasonic sensor in real time with freeRTOS

CAN bus does not work

Hello,I am using the STM32F7 in my project, which uses the CAN1. I create the project from cubemx and connect it to a STM32F4 evaluation board to test. I can see the Can signal via the oscillations cope after the transceiver, but no interrupt can be ...

Trying to set the system clock on an stm32f3discovery board yields an hard fault.

Hi.,I am very very new to micro controller programming and hit a wall very early on.I have an stm32f3 discovery board which is an stm32f303 vct6.I generated code with PINs 8 through 15 being output pins within stm32 cube and imported that code into c...
