How to apply SPI between ESP8266 and STM32f07 with FreeRTOS ? Recently, I've been worked with the esp8266 and stmf407 discovery board.I used stm32f407 (master), and connect to esp8266 (slave) via SPIHowever, the package I got always missed 1 package. To be more specific, I've tried to send some uint8_t dummy datas, but all the results i got always had a missing part.Arduino code in esp8266 :https://github.com/esp8266/Arduino/blob/master/libraries/SPISlave/examples/SPISlave_Test/SPISlave_Test.inouvision code :void StartDefaultTask(void const * argument)
{
/* USER CODE BEGIN 5 */
/* Infinite loop */
for(;;)
{
xSemaphoreTake(DeliverHandle,portMAX_DELAY);
xSemaphoreGive(DeliverHandle);
osDelay(20);
}
}
void StartTask02(void const * argument)
{
/* USER CODE BEGIN StartTask02 */
/* Infinite loop */
uint8_t SPI_data[4]={0x01,0x02,0x03,0x04};
for(;;)
{
xSemaphoreTake(DeliverHandle,portMAX_DELAY);
//ss low
WPC_GPIO_Write_Pin(GPIOA,GPIO_PIN_15, 0x00); //CS = 0
//spi transmit
HAL_SPI_Transmit(&hspi2,SPI_data,4,1000)
