This will guide through the steps to flash the firmware on the attiny84 microcontroller found on some RPICT series.
Required equipment
- 1 Arduino UNO
- 6 Jumper wires
Connections
Connect the wires between the Arduino UNO and the RPICT board as follow:
| Arduino | RPICT |
|---|---|
| 10 | Rst |
| Gnd | Gnd |
| 13 | SCK |
| 11 | MOSI |
| 12 | MISO |
| 5V | VCC |
ISP Sketch
Open the Arduino IDE and open the file Files | Examples | ArduinoISP
Upload it to the Arduino uno. Make sure that Tools | Board: Arduino/Genuino UNO is selected.
Upload the Attiny sketch
Download the sketch that you wish to upload. Open it with the Arduino IDE.
Select Tools | Board: ATtiny 24/44/84
Then select Tools | Burn Bootloader
Now select Sketch | Upload Using Programmer
You must now reload the config with the lcl-rpict-config tool on the Raspberrypi.
