stm32使用SDIO与esp32通讯失败
Posted: Thu Sep 21, 2023 2:10 am
我目前正在使用stm32的sdio接口与esp32-WROOM-32U通讯，我已经按照文档移植了host代码到stm32f429igT6，esp32端也使用编译好的sdio-at固件,并烧录成功这是esp32端日志：

IO13，IO14, IO15, IO2, IO4, IO12 这 6 个管脚使用10K 欧姆电阻进行上拉连接到stm32的sdio引脚；
下面是stm32的sdio部分初始化代码，其他地方没有做修改：
sdio_err_t sdio_driver_init(void)
{
sdio_init_t sdio_init = {
.width = WIDTH_4, //历程是WIDTH_1，也尝试了，并不起作用
.clock = 400000 // 12M clock
};
sdio_recv_SemHandle = xSemaphoreCreateBinary();
STM32SdioInit(sdio_init);
return SDIO_SUCCESS;
}
在初始化中调用了下面的函数：
void UserEsp32Init(void)
{
sdio_err_t err;
SDIO_LOGI(TAG, "host ready, start initializing slave...");
//HAL_GPIO_WritePin(GPIOC, WIFI_EN_Pin, GPIO_PIN_SET);
err = sdio_host_init();
if(err != SDIO_SUCCESS) {
printf("SDIO init error\r\n");
return;
}
printf("Sdio init done\r\n");
//xTaskCreate(sdio_send_task, "sdioSendTask", ESP32_SIZE, NULL, osPriorityNormal1, NULL);
//xTaskCreate(sdio_recv_task, "sdioRecvTask", ESP32_SIZE, NULL, osPriorityNormal1, NULL);
}
下面是stm32的打印，首先已经做了3s的延时等待esp32启动再进行host的初始化：
