If you use these or edit them please leave my name or mention of where you got them.
Installation of Drivers (Run each command one line at a time in the terminal unless specified):
sudo nano /etc/modules-load.d/fbtft.conf
add these 2 lines to the file
spi-bcm2835
fbtft_device
Ctrl + O to save then Ctrl + X to exit
sudo nano /etc/modprobe.d/fbtft.conf
copy entire code below into the opened file
options fbtft_device custom name=fb_st7789v speed=81000000 rotate=270 fps=60 buswidth=8 gpios=reset:25,dc:24 modprobe flexfb setaddrwin=0 width=240 height=320 init=-1,0x11,-2,120,-1,0x36,0x00,-1,0x3A,0x05,-1,0xB2,0x08,0x08,0x00,0x33,0x33,-1,0xB7,0x35,-1,0xBB,0x1A,-1,0xC2,0x01,-1,0xC3,0x3F,-1,0xC4,0x26,-1,0xC6,0x0E,-1,0xD0,0xA4,0xA1,-1,0x21,-1,0xE0,0x00,0x19,0x1E,0x0A,0x09,0x15,0x3D,0x44,0x51,0x12,0x03,0x00,0x3F,0x3F,-1,0xE1,0x00,0x18,0x1E,0x0A,0x09,0x25,0x3F,0x43,0x52,0x33,0x03,0x00,0x3F,0x3F,-1,0x29,-3
Ctrl + O to save then Ctrl + X to exit
Now it's time to install the FBCP software (enter 1 line at a time)
sudo apt-get update
sudo apt-get install cmake git
git clone https://github.com/tasanakorn/rpi-fbcp
cd rpi-fbcp/
mkdir build
cd build/
cmake ..
make
sudo install fbcp /usr/local/bin/fbcp
Ctrl + O to save then Ctrl + X to exit
We need to add the fbcp to boot everytime to initiate the LCD so we are going to edit a file and add a line of code for this
sudo echo "/usr/local/bin/fbcp &" >> /etc/rc.local
We need to edit the config.txt and add these lines at the end of the text file.
sudo nano /boot/config.txt
hdmi_force_hotplug=1
hdmi_group=2
hdmi_mode=87
hdmi_cvt=640 480 60 1 0 0 0
disable_overscan=1
dtparam=spi=on
Ctrl + O to save then Ctrl + X to exit
Finally Reboot the Pi and see the LCD work by typing:
sudo reboot -h now
