The background project for this code could be a simple calculator using an Arduino 3.2" TFT LCD Touch Screen. The touch screen would have buttons that perform basic arithmetic operations such as ...

For example an spi display or TV-out (using the TV-out library, probably on a second arduino). Reason for me to ask, I’ve got a Yamaha PSR-S500 with defective display, new displays are around ...

The 16×2 LCD unit is directly connected to the Arduino Uno board in 4-bit mode. Data pins of the LCD, namely RS, EN, D4, D5, D6, D7, are connected to Arduino digital pins D7, D6, D5, D4, D3, D2. The ...

I hooked them up to an Arduino Uno board with a Parallax Serial 16×2 Character LCD. I got both ICs working in separate sketches that I’ve blogged about previously, but I wanted one combined program.
