Is there anyone who can run the SPI of CH32V103? [Copy link]

 

Has anyone run SPI bus successfully these days? I have been running SPI for three days, but I can't even find the signal through the oscilloscope. If you know, please give me some tips

PA5 -->SPI_CLK

PA7 -->SPI_MOSI

The calling situation in the main program. I call SPI to send a signal in the ssd1306_Init program.

	u8 i=0;
    NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);
    Delay_Init();
	USART_Printf_Init(115200);
	printf("SystemClk:%d\r\n",SystemCoreClock);
	GPIO_Toggle_INIT();
	SPI_FullDuplex_Init();

	Delay_Ms(2000);
	printf("This is SPI  example\r\n");
	GPIO_WriteBit(GPIOB, GPIO_Pin_11, Bit_SET);
	ssd1306_Init();
	//GPIO_WriteBit(GPIOB, GPIO_Pin_11, Bit_RESET);
	printf("Host Mode\r\n");

The initialization of the pins is like this.

The OLED screen is tested and is good on the STM32G431 development board

I also can't use the hardware spi driver, and it reports a port error when I try to debug. Have you solved it?
