Probleme on getting clock signal on SPI slave device, Hi ,i have a problem with SPI slave device, it doesn't receive the clock signal from stm32f103 (Master), i have configured the baud rate correctly : 72Mhz/32 (SPI1), which is inside the range clock freq of slave device, CS pin is active low so when i send a command i set CS = 1(low), i have checked many parameters but i still have nothing in clk clock, MOSI , MISO line are ok, as shown in these pictures below, please if anyone has any suggestion ! this is the SPI1 config codevoid SPI1_init(void){
//1 : Configure SPI1 GPIO's
//---------------------------
// Enable clocks for PORTA, PORTC and SPI1 peripheral
RCC->APB2ENR |= RCC_APB2ENR_IOPAEN;
RCC->APB2ENR |= RCC_APB2ENR_IOPCEN;
// Setup (PA4-->NSS /PA5-->SCK / PA6-->MISO / PA7-->MOSI) as Alternate function for SPI1
// PA4 --> CS as Output AF push-pull (50Mhz) ref p167-161
GPIOA->CRL |= GPIO_CRL_MODE4_0 ;
GPIOA->CRL |= GPIO_CRL_MODE4_1;
GPIOA->CRL &=~ GPIO_CRL_CNF4_0;
