How to do a TIC-80 byte-jam on an ARM mac

Byte jams are a fun demoscene event where there's usually music from a DJ and several participants who use the TIC-80 fantasy console to code up a graphics effect from scratch within an hour. I usually watch the Field-FX stream on Monday evenings, and occasionally take part; there's an archive of the graphical effects people have made in these sessions, here.

A rather neat part of this is that TIC-80 has been modified to allow its programs to access the FFT of a sound stream, so that you can make your programs respond to the music in real-time. However, this can require a bit of setup on a mac.

In this document I will describe how to set up the audio software, plus byte jam client and TIC-80 itself, to allow participation in a byte jam.

ESP32 as Bluetooth Keyboard

With its built-in Bluetooth capabilities, the ESP32 can act as a Bluetooth keyboard. The below code is a minimal example of how to achieve it. It will generate the key strokes for a message whenever a button attached to the ESP32 is pressed.

For the example setup, a momentary button should be connected to pin 2 and to ground. Pin 2 will be configured as an input with pull-up.

In order to receive the message, add the ESP32 as a Bluetooth keyboard of your computer or mobile phone:

Go to your computers/phones settings
Ensure Bluetooth is turned on
