VCC    ->    PIN2
GND    ->    PIN6
DIN    ->    PIN19 (GPIOX_8)
CLK    ->    PIN23 (GPIOX_11)
CS     ->    PIN24 (GPIOX_10)
DC     ->    PIN29 (GPIOX_17)
RST    ->    PIN31 (GPIOX_18)
BUSY   ->    PIN18 (GPIOX_15)
  1. Follow instructions at https://www.waveshare.com/wiki/7.5inch_e-Paper_HAT_(B)_Manual but using the command make LIBRETECH -j4 EPD=epd7in5bV2

Bypassing obtaining an spi:/dev/dspidev0.0 … I think I can create work-around …
How does one correctly do the step:
"
#Open the Raspberry Pi terminal and run the following commands:
sudo apt-get update
sudo apt install gpiod libgpiod-dev
"
we forget that gpiod and libgpiod-dev are both dependent on RPi.GPIO… Still trying to figure out how to build a functional Libre.GPIO.h. Should I connect via GitHub to push something to … libre-computer-project/python3-libretech-gpiod?

OK … so scratch the earlier problems… solve them later … How do we get beyond…

No Rule to make target LIBRETECH . Stop.
