Alert-Me Display

A simple application for an nRF52840 microcontroller using embassy.

It shows information received with BLE on a HD44780 LCD like screen.

This is a learning environment, not a finished product.

Development

If using the nix way as described in the top-level readme, no further dependencies need to be installed.

In addition to the top-level readme dependencies, the following has to be installed:

The softdevice blob is not distributed with this repository for licensing reasons (even though my understanding is that it is possible).

Download the S140 Softdevice and flash it to your chip.

Example command to flash the softdevice

probe-rs download --verify --format hex --chip nRF52840_xxAA ./s140_nrf52_7.3.0_softdevice.hex

Verify that the microcontroller is recognized by running probe-rs list.

A simple cargo run will then connect to it and upload the code. Logging output should be visible.
