README
README.mdUINIO-MCU-RP2040 核心板
UINIO-MCU-RP2040 是一款基于树莓派 RP2040 微控制器的核心板，该主控芯片采用 ARM Cortex-M0+ 双核心，运行频率高达 133MHz，片上内置有 264KB 容量的 SRAM 内存，并且能够外接高达 16MB 容量的片外 Flash 闪存（通过专用的 QSPI 总线进行连接），并且还集成有 DMA 控制器，以及 30 个 GPIO 引脚（其中 4 个可用作模拟输入）。除此之外，片上还拥有 2 个 UART 控制器、2 个 SPI 控制器、2 个 I²C 控制器，以及 16 个 PWM 通道。同时还支持 USB 1.1 设备和主机模式，以及 USB 大容量存储启动模式和拖放式编程。
设计概要
- Flash 存储芯片采用了更加小巧的
WSON8封装； - 添加
SOD123封装的肖特基势垒二极管，用于防止正负级错误的反接； - 预留有
2mm的固定螺丝孔，便于安装至 3D 打印外壳，或者搭建成套的产品原型； - 添加了用于全局异步复位的 RESET 按钮（低电平有效），便于在上电状态进行复位操作以及更新固件；
- 引出了官方 Pico 开发板没有的
GPIO23和GPIO24两个引脚资源，并且在GPIO25引脚采用了与 Pico 相同的测试用 LED 发光二极管； - 由于 ADC 引脚内部集成有连接至
IOVDD（3.3V）的反向二极管，所以采用了 FET 场效应管 DMG1012T 防止在 RP2040 没有上电的时候，这些引脚上施加的电压通过ADC3引脚泄露到3.3V电源网络；
注意： 核心板引脚顺序并不完全兼容官方的 Raspberry Pi Pico 开发板。
固件更新
UINIO-MCU-RP2040 的固件更新操作流程如下面步骤所示：
- 按住 BOOT 按键不放，将核心板的 Type-C 接口连接到电脑的；
- 等待 1 秒钟之后，松开 BOOT 按键，此时计算机会自动将 UINIO-MCU-RP2040 识别为可移动磁盘；
- 将等待下载的固件拖动或者复制到该可移动磁盘当中，此时 RP2040 主控会自动重启并且加载固件；
