Normally, I don't explain how to assemble the device, but this one is customized with many parts, so let's follow my guide. [Prepare Parts] 1. Raspberry Pi Zero/Zero W 2. LCD LI9341 2.4" https://www.aliexpress.com/item/32845726230.html 3. Battery: I use a 1100mAh battery from an RC Quadcopter https://www.aliexpress.com/item/32998946471.html 4. Tactile Push Button: https://www.aliexpress.com/item/32699672450.html 5. Speaker https://www.aliexpress.com/item/32957581480.html or https://www.aliexpress.com/item/32868028612.html 6. Tactile Button: https://www.aliexpress.com/item/32421199551.html or https://www.aliexpress.com/item/32668706990.html 7. TP4056 LIPO Charging Board https://www.aliexpress.com/item/32709366716.html 8. PAM8403 Amplifier Board https://www.aliexpress.com/item/32663074926.html 9. Universal PCB Board https://www.aliexpress.com/item/32858951350.html 10. Resistors: 270R, 150R 11. Capacitors: 33N, 10U 12. Screw Set: https://www.aliexpress.com/item/32735936901.html [Build] - Wire the LCD to the Pi Zero using these pins: Screen <--------> Raspberry Pi 3 or zero SDO (MISO) <-----> Pin 21 LED <-----------> Pin 2 (5V) SCK <-----------> Pin 23 SDI (MOSI) <-----> Pin 19 DC <------------> Pin 22 RESET <---------> Pin 26 CS <------------> Pin 24 GND <-----------> Pin 20 VCC <-----------> Pin 1 (3.3V) - Cut the Universal PCB to create a controller with Up, Down, Left, Right, and A, B, X, Y buttons. - Burn Retropie SD (any version). - Run on screen via HDMI or connect via USB following this guide: https://www.instructables.com/id/Connect-to-a-Raspberry-Pi-Zero-W-Via-USB-No-Mini-H/ - Go to the shell and run these commands: [Install Driver] git clone https://github.com/juj/fbcp-ili9341.git cd fbcp-ili9341 mkdir build cd build cmake -DSPI_BUS_CLOCK_DIVISOR=6 -DILI9341=ON -DSINGLE_CORE_BOARD=ON -DGPIO_TFT_DATA_CONTROL=25 -DGPIO_TFT_RESET_PIN=7 -DSTATISTICS=0 -DDISPLAY_ROTATE_180_DEGREES=ON .. make -j (for testing, use this command) sudo ./fbcp-ili9341 After these steps, if everything is correct, the LCD screen should display something. - Make it run every time after boot: sudo nano /etc/rc.local add the following line: sudo ./fbcp-ili9341 & - Install GPIO Buttons following this tutorial: https://othermod.com/gpio-buttons/ and map GPIO like this: Map GPIO like this: UP 23 # Up DOWN 27 # Down LEFT 22 # Left RIGHT 17 # Right Q 19 # Y ESC 16 # B Y 20 # X ENTER 26 # A LEFTCTRL 1 # L1 RIGHTCTRL 21 # R1 Z 24 # L2 X 5 # R2 S 0 # Start D 6 # Select - Add sound to GPIO 13 (pwm) by adding a sound filter: add this line to config.txt: dtoverlay=pwm,pin=13,func=4 and if you want to fix audio hiss, add these lines also: disable_audio_dither=1 force_pwm_open=0 - Connect every wire from the buttons to the Pi Zero. - Close and run. I hope this guide helps those interested in building this device. Sorry for my poor language and tutorial. I believe those who want to build this device will understand what to do.
