Hello!I'm trying to run SPI in Transmit Only Master mode.It's strange - result of HAL_SPI_Transmit is HAL_OK but I can't see any signals on SCK and MOSI pins.main.cint main(void) { /* USER CODE BEGIN 1 */ /* USER CODE END 1 */ /* MCU Config...

Hello!After somet tests on Nucleo and Discovery I wan't to make some more complicated and practice project. I'm trying to make WAV file player from microSD card file.Hardware is based on STM32F103RCT6 connected with microSD card socket and DAC (PCM17...

I disabled JTAG in HAL_MspInit function, so before SPI init, but...I aslo want to use PB4 as GPIO so I added "__HAL_AFIO_REMAP_SWJ_NONJTRST();" too.Then I have value 0x060 in SWJ_CFG register.I find table in RM0008 where is no 011 value. So I use onl...

Good idea! I tried this:SPI3 MISO (PB5) - toggle okSPI3 SCK (PB3) - no reactionSCK is also SYS_JTDO so I add to HAL_MspInit:__HAL_AFIO_REMAP_SWJ_NOJTAG();After that SCK toggle too. When I turn on SPI I don't have any signal again :\I fund in F1 HAL d...

Thank you for reply STM32 model is STM32F103RCT6Registers before init: Registers after SPI init:Registers after transmit: Is it correct?

Thank you for suggesions. Debugging with sinewave was helpfull Finally I founded 2 problems:1) I have int16_t type buffer (2 bytes), but function f_read need amount of data to read in bytes. When I sended AUDIO_BUFFER_SIZE / 2 it read only 1/4 buffe...
