Bulletin

A little screen that sits at my desk and display whatever I pass to it via serial port

This only uses espressif's esp32 SDK esp-idf. Does not require arduino IDE!

Build

• cd firmware
• ./configure
• source ./esp-idf/export.sh
• make build
• make flash

Example

The example provides a simple python script that reads lines from lyrics.txt and sends the data serially to the esp32 chip.
