This file is to help you use this routine.
Since our ink screens are getting more and more, it is not convenient for our maintenance, so all the ink screen programs are made into one project.
A brief description of the use of this project is here:

1. Basic information:
This routine was developed based on the jetson-nano-sd-r32.1-2019-03-18 system 
image. Since the current system does not have a hardware SPI,Currently developed 
with analog SPI, so the ink screen refresh rate is slower;
This routine was developed based on the Jetson Nano and the routines were 
verified on the Jetson Nano;
This routine has been verified using the e-paper Driver HAT module. 
You can view the corresponding test routines in the examples\ 
of the project.

2. Pin connection:
Pin connections can be viewed in \lib\epdconfig.py and will be repeated here:
EPD    =>    Jetson Nano/RPI(BCM)
VCC    ->    3.3
GND    ->    GND
DIN    ->    10(SPI0_MOSI)
CLK    ->    11(SPI0_SCK)
CS     ->    8(SPI0_CS0)
DC     ->    25
RST    ->    17
BUSY   ->    24

3.Installation library
    sudo apt-get update
    sudo apt-get install python-pip
    sudo apt-get install python-pil
    sudo pip install Jetson.GPIO

or

    sudo apt-get update
    sudo apt-get install python3-pip
    sudo apt-get install python3-pil
    sudo pip3 install Jetson.GPIO

4. Basic use:
Since this project is a comprehensive project, you may need to read the following for use:
You can view the test program in the examples\ directory.
Please note which ink screen you purchased.
Chestnut 1:
     If you purchased 5.83inch e-paper, then you should execute the command:
     Sudo python epd_5in83_test.py
Chestnut 2:
     If you buy a 2.9inch e-paper (B), since the 2.9-inch Type B and Type C are common driver codes,
     Then you should execute the command:
     Sudo python epd_2in9bc_test.py
    
Note: For epd_1in54_V2_test.py and epd_2in13_V2_test.py, please note that the V2 logo is attached to the back of your screen.
