AVR firmware for wireless touch pad (nRF24L01+)

Features

1. Wireless touch pad sensor for ATMega 168/328 microcontrollers with nRF24L01+ transceiver.
2. Power consumption in the sleep mode approximately 2 uA.
3. Transmits device identifier and battery voltage level on each touch event.
4. Battery measurement through internal ADC with 1.1 V bandgap reference.
5. Wake-up from power-down mode by external interrupt on rising edge.
6. Supports ATMega168, ATMega168P, ATMega168PB, ATMega328, ATMega328P, ATMega328PB.
7. Easy installation into any standard touch pad enclosure.

Attention

1. A compatible RF Gateway is required to receive and process transmitted packets.
2. After power-on reset the first touch event may not trigger a transmission.
3. Multi-touch is not supported, only a single touch event per transmission cycle.
4. Changing gateway address or channel requires reflashing the microcontroller.

Using

In an existing PlatformIO project, run the following command to install the firmware:

cd your_project
git clone https://github.com/aZholtikov/zh_avr_touch_pad
