Hello, everyone, I have a question about connecting the TFT 1,44" on an Arduino Nano. My pinout of the st7735 is different and I don't want to burn my screen. my pinout is :
led-sck-sda-a0-reset-cs-gnd and vcc. pins are 1 tem 8. How do you connect on an Arduino Nano? What is A0?
Thanks for help.
That pin A0 is equivalent to D/C or DC, it is the data pin, it is connected to a PWM pin, sometimes it goes to pin 9. The reset pin is connected to pin 8
The CS pin pretty much tells me it's an SPI display, so I'd wager that A0 pin is really D/C.
The most important thing to remember is that the ST7735 controller will be expecting 3.3V level signals, so you'll need level converters to bring down the 5V level signals that the Nano will be putting out.
Edit: see the LCD Wiki for lots more info on what I suspect is your display.
