Arduino with Multiple Displays – Part 3

Whilst messing around a little more with my Arduino with Multiple Displays – Part 2, I've optimised the code a little and found out a bit more about these displays! In this part, I'm actually using a PCB that can hold four displays, powered by a Waveshare Zero device. More on that here: Waveshare Zero Multi … Continue reading Arduino with Multiple Displays – Part 3 →

Waveshare Zero Multi Display PCB Design

Following on from my Arduino with Multiple Displays – Part 2, using a Waveshare Zero type module, I wanted to try even more displays in parallel. I don't know what the performance implications will be, or even if it is possible, but I do know I don't really want to be using jumper wires to try … Continue reading Waveshare Zero Multi Display PCB Design →

Arduino with Multiple Displays – Part 2

As I mentioned in my last post on Arduino with Multiple Displays I'm going to look at other microcontrollers too. This post takes a wander through my Waveshare Zero and similar format boards that each support one of the RP2040, ESP32-C3 or ESP32-S3. Warning! I strongly recommend using old or second hand equipment for your experiments. … Continue reading Arduino with Multiple Displays – Part 2 →

Arduino with Multiple Displays

A while back I tried to use several SSD1306 displays with an Arduino (see OLED MIDI Display – Part 2) and got into trouble with memory. I have another need for multiple displays coming up, so thought I'd revisit the idea to see what could be done. This shows use to use several cheap SPI-based displays … Continue reading Arduino with Multiple Displays →

TFT MIDI Display – Part 3

This display is inspired by the sound and light show at the end of Close Encounters of the Third Kind. It uses the TFT MIDI Display once again. https://youtu.be/hEpZ7Zy03Vo Warning! I strongly recommend using an old or second hand keyboard for your MIDI experiments. I am not responsible for any damage to expensive instruments! These are the … Continue reading TFT MIDI Display – Part 3 →

TFT MIDI Display – Part 2

Building on my previous project adding a colour display to an Arduino, I thought I'd use the graphics a little by adding one of those "show the note on the stave" displays you quite often get on modern keyboards. In Part 3 I preset an alternative visualisation. https://youtu.be/p_eLd95G4zc Warning! I strongly recommend using an old or … Continue reading TFT MIDI Display – Part 2 →

TFT MIDI Display

This project uses a cheap 1.8" colour 128x160 TFT display based on a ST7735 driver chip which is available very cheaply in the usual places. The display links up to an Arduino using the SPI bus as described here and there is a nice little library to talk to it provided by Adafruit for use … Continue reading TFT MIDI Display →
