[GUIDE] Building Experimental Display Driver with Custom Settings
Was asked to make a short guide on compiling the experimental display driver with custom overscan settings, so here we go. This is primarily for those that wish to be able to change the overscan.

# First, use cd to go to the directory you want to clone the repository into, then:
git clone https://github.com/juj/fbcp-ili9341
cd fbcp-ili9341
mkdir build
cd build
nano ../freeplaytech_waveshare32b.h #This file has, on the end of the last 4 lines, the overscan values that you can change. Make sure to read the comment above it for information about which side is which
#After saving and quitting or commenting out sleep lines 145, 149, and 153
make -j
sudo systemctl stop fbcp[variant].service #replace [variant] with the current version of the driver you are using; usually will be fbcpFilled or fbcpCropped
sudo ./fbcp-ili9341 #runs the built binary, use Control-C to exit
#You will probably need to edit the freeplaytech_waveshare32b.h file multiple times to get the overscan correct, so after doing so:
sudo cp ./fbcp-ili9341 /usr/local/bin/fbcp[variant] #replace [variant] with the version of the driver you want to replace, and use sudo systemctl enable/disable to make it the only version running
#You can optionally copy and rename one of the other service files from /lib/systemd/system/fbcp[variant].service, editing the ExecStart field to point to where the new binary is
If you have any questions, feel free to reply to this thread.
