尝试用树莓派处理ESP32-DevKitC
- ESP32-DevKitC V4 入门指南
- 快速入门
- Linux 平台工具链的标准设置
- esp32_devkitc_v4-sch.pdf
- esp32_technical_reference_manual_cn.pdf
- ESP32芯片有34个物理GPIO pad。每个pad都可用作一个通用IO，或连接一个内部的外设信号。
- 这34个物理GPIO pad的序列号为：0-19, 21-23, 25-27, 32-39。其中GPIO 34-39仅用作输入管脚，其他的既可以作为输入又可以作为输出管脚。
- 树莓派
- sudo apt-get install git wget flex bison gperf python python-pip python-setuptools cmake ninja-build ccache libffi-dev libssl-dev dfu-util
- 已经有python3，不用装，没有就装一下：
- sudo apt-get install python3 python3-pip python3-setuptools
- 不需要设置：sudo update-alternatives --install /usr/bin/python python /usr/bin/python3 10
- 获取 ESP-IDF
- mkdir -p ~/esp
- cd ~/esp
- git clone --recursive https://github.com/espressif/esp-idf.git
- 大清早六点钟的时候下载超级快
- cd esp-idf && pwd cd

- pip安装软件timeout修改参考：0159_pip_source_modify.md
- 尝试编译
- cd ~/esp
- . ~/esp/esp-idf/export.sh
- cp esp-idf/examples/get-started/hello_world . -r
- cd hello_world
- idf.py set-target esp32
- idf.py menuconfig
- idf.py build
- 烧录及查看log
- 插入usb线，发现设备
- /dev/ttyUSB0
- idf.py -p /dev/ttyUSB0 flash (这里的flash只是写入，不会自动重启，当使用后面的moniter程序的时候，相当会重启，可以看到完整的log)
