I am pretty sure I did not meddle with the sdkconfig file between the time when it worked (about 7 days ago?) and today. I tried cloning ESP-IDF into another folder and copied my application's main.c file over t
调用spi_bus_add_flash_device()将片外FLASH作为从设备挂载到SPI总线,并分配内存、填充esp_flash_t结构体、初始化CS信号线 调用esp_flash_init()与芯片进行通信(注意:目前多个FLASH芯片可以连接到同意总线,但尚不支持在同一个SPI总线上使用esp_flash_*和spi_device_*设备) 访问FLASH 一般来说应尽量避免对主SPI ...
