Hardware Connection

For the 8-bit parallel TFT screen, the following data lines D0 to D7, along with read, write, chip select, data/command switching, and reset signal pins need to be connected. Ensure to adjust the following pin definitions according to your specific hardware:

• D0-D7 - 8-bit data lines
• WR - Write signal
• RD - Read signal (if not using the read function, it can be connected to VCC)
• CS - Chip select signal
• DC - Data/command switching signal
• RST - Reset signal

Usage Method

Installing Library Files (skip this step if already installed)

1. Open the Arduino IDE.
2. Go to “Tools” > “Manage Libraries…”.
3. Search for “MCUFRIEND_kbv” and “Adafruit GFX”, and install each library individually.

Enter the code:

For the 1.14-inch ST7789V screen with a resolution of 135x240 pixels using an 8-bit parallel interface, there aren't many available parallel libraries in the Arduino IDE. Therefore, we have written a library file based on this screen.

INFO

.CPP

Place the file in the project folder, at the same level as the .ino file.

Next, write the following code in the .ino file:
