正点原子ESP32-S3开发板使用的接口是MicroSD卡接口，卡座带自锁功能，SD SPI主机驱动程序基于SPI Master Driver实现。借助SPI主控驱动程序，SD卡及其他SPI设备可以共享同一SPI总线。SPI主机驱动程序将处理来自不同任务的独占访问。在本章中，我们将向大家介绍，如何在正点原子ESP32-S3开发板上实现MicroSD卡的读取。本章...

Also, part of the firmware has blobs in it, but a lot of the firmware and all of the driver are modifiable in case you need your ESP32 to do even more than Espressif has coded in – this is not fully open-source firmware, but it’s definitely way more than the Broadcom’s ...
ESP32 的 SPI LCD 接口的示例程序参考 esp-iot-solution/tree/master/examples/hmi,适配的 LCD 的驱动库可参见 esp-iot-solution/components/display/screen/controller_driver。 默认使用的是 ILI9341 LCD 。 ESP32 的 8080 并口的例程可参见 esp-iot-solution/examples/screen 例程。对于 8080 协议的 LCD 接口,...
