这个文件是帮助您使用本例程。
|
||||
在这里简略的描述本工程的使用：
|
||||
|
||||
1.基本信息：
|
||||
本例程使用相对应的模块搭配Pico进行了验证，你可以在工程的中查看对应的测试例程;
|
||||
|
||||
2.管脚连接：
|
||||
管脚连接你可以在Pico_ePaper-xxx.py查看，这里也再重述一次：
|
||||
EPD => Pico
|
||||
VCC -> VSYS
|
||||
GND -> GND
|
||||
DIN -> 11
|
||||
CLK -> 10
|
||||
CS -> 9
|
||||
DC -> 8
|
||||
RST -> 12
|
||||
BUSY -> 13
|
||||
|
||||
3.基本使用：
|
||||
1): 按住Pico板上的按键，将pico通过Micro USB线接到电脑的USB接口，然后松开按键。
|
||||
接入之后，电脑会自动识别到一个可移动盘（RPI-RP2）
|
||||
|
||||
2): 将python目录中Pico.uf2 / Pico 2.uf2 文件复制到识别的可移动盘（RPI-RP2）中
|
||||
|
||||
3): 更新Thonny IDE
|
||||
sudo apt upgrade thonny
|
||||
|
||||
4): 打开Thonny IDE （点击树莓logo -> Programming -> Thonny Python IDE ）
|
||||
选择Tools -> Options... -> Interpreter
|
||||
选择MicroPython(Raspberry Pi Pico 和ttyACM0端口
|
||||
|
||||
5): 在Thonny IDE中打开python/Pico_ePaper-xxx.py文件
|
||||
然后运行当前脚本（绿色小三角）即可

This file is to help you use this routine.
|
||||
Here is a brief description of the use of this project:
|
||||
|
||||
1. Basic information:
|
||||
This routine has been verified using the corresponding module with Pico,
|
||||
you can view the corresponding test routine in the project;
|
||||
|
||||
2. Pin connection:
|
||||
You can check the pin connection at Pico_ePaper-xxx.py, and repeat it here:
|
||||
EPD => Pico
|
||||
VCC -> VSYS
|
||||
GND -> GND
|
||||
DIN -> 11
|
||||
CLK -> 10
|
||||
CS -> 9
|
||||
DC -> 8
|
||||
RST -> 12
|
||||
BUSY -> 13
|
||||
|
||||
|
||||
3. Basic use:
|
||||
1): Press and hold the button on the Pico board, connect Pico to the USB port of the
|
||||
computer through the Micro USB cable, and then release the button.
|
||||
After connecting, the computer will automatically recognize a removable disk (RPI-RP2)
|
||||
|
||||
2): Copy the Pico.uf2 / Pico 2.uf2 file in the python directory to the recognized
|
||||
removable disk (RPI-RP2)
|
||||
|
||||
3): Update Thonny IDE
|
||||
sudo apt upgrade thonny
|
||||
|
||||
4): Open Thonny IDE （Click raspberry logo -> Programming -> Thonny Python IDE ）
|
||||
select Tools -> Options... -> Interpreter
|
||||
select MicroPython(Raspberry Pi Pico and ttyACM0 port
|
||||
|
||||
5): Open the python/Pico_ePaper-xxx.py file in Thonny IDE
|
||||
Then run the current script (green triangle)
