rust-arduino-demo

============

Rust project for the Arduino Uno. This is a simple demo using the built in ADC to provide data for configurable IIR low and high pass filters of the first order.

Channel 0 (A0) is used to convert an analog signal which is then filtered and sent to Port B and D via PD2 to PD7 and PB0 to PB2. The filter can be switched via PB5 and the frequency can be set via PC1 to PC5 (Pins A1 to A5).

PB3 and PB4 provide input and output signalling for a latch.

Build Instructions

1. Install prerequisites as described in the avr-hal README (avr-gcc, avr-libc, avrdude, ravedude).

2. Run cargo build to build the firmware. If you want the hex files for simulation run cargo build a second time. This step is only needed once. Hex files will be produced thereafter with every build unless you run cargo clean which then requires you to run twice again.

3. Run cargo run to flash the firmware to a connected board. If ravedude fails to detect your board, check its documentation at https://crates.io/crates/ravedude.

4. ravedude will open a console session after flashing where you can interact with the UART console of your board.

Produced Output

You will find the hex files for simulation in the avr-atmega328p directory of the target directory.
