RPI Zero 2 W Adafruit 1.3? Color TFT Bonnet for Raspberry Pi retro pi
Write the retropi image to the sdcard.
Mount the boot partition.
Setup ssh by creating a file on the boot partition called ssh
setup wifi by creating wpa_supplicant.conf with the following content
country=US
ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev
update_config=1
network={
ssid=”YourNetworkName”
psk=”YourPassword”
}
Edit the config.txt file and add the following cdmi configuration lines
hdmi_group=2
hdmi_mode=87
hdmi_cvt=240 240 60 1 0 0 0
hdmi_force_hotplug=1
and then the following button mappings
dtoverlay=gpio-key,gpio=17,active_low=1,gpio_pull=up,keycode=103
dtoverlay=gpio-key,gpio=22,active_low=1,gpio_pull=up,keycode=108
dtoverlay=gpio-key,gpio=27,active_low=1,gpio_pull=up,keycode=105
dtoverlay=gpio-key,gpio=23,active_low=1,gpio_pull=up,keycode=106
dtoverlay=gpio-key,gpio=4,active_low=1,gpio_pull=up,keycode=28
dtoverlay=gpio-key,gpio=5,active_low=1,gpio_pull=up,keycode=48
dtoverlay=gpio-key,gpio=6,active_low=1,gpio_pull=up,keycode=30
Next put the card in the machine reboot, it will reboot twice as it resizes the partition.
Ssh in and we’re going to build the screen monitor.
cd ~
git clone https://github.com/juj/fbcp-ili9341.git
cd fbcp-ili9341/
edit config.h
comment out #define DISPLAY_OUTPUT_LANDSCAPE
//#define DISPLAY_OUTPUT_LANDSCAPE
uncomment //#define BACKLIGHT_CONTROL
#define BACKLIGHT_CONTROL
edit st7735r.cpp and find the following line.
#define MADCTL_ROTATE_180_DEGREES (MADCTL_COLUMN_ADDRESS_ORDER_SWAP | MADCTL_ROW_ADDRESS_ORDER_SWAP)
remove MADCTL_COLUMN_ADDRESS_ORDER_SWAP
#define MADCTL_ROTATE_180_DEGREES (MADCTL_ROW_ADDRESS_ORDER_SWAP)
run the following
cmake -DST7789=ON -DGPIO_TFT_BACKLIGHT=26 -DARMV8A=ON-DBACKLIGHT_CONTROL=OFF -DSTATISTICS=0 -DSPI_BUS_CLOCK_DIVISOR=6 -DGPIO_TFT_DATA_CONTROL=25 -DDISPLAY_ROTATE_180_DEGREES=ON ./;make -j; sudo ./fbcp-ili9341
You should now see the welcome screen from retropi
if you want it to start at boot use the following
sudo install -t /usr/local/sbin fbcp-ili9341
sudo install -m 0644 -t /etc fbcp-ili9341.conf
sudo install -m 0644 -t /etc/systemd/system fbcp-ili9341.service
sudo systemctl daemon-reload
sudo systemctl enable fbcp-ili9341 && sudo systemctl start fbcp-ili9341
