Burn bootloader on RPICT Atmega with Arduino UNO

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

NanoProg is a more appropriate tool for this operation.

Connections

Connect the wires between the Arduino UNO and the RPICT board as follow:

Arduino RPICT
10 RESET
Gnd Gnd
13 SCK
11 MOSI
12 MISO
5V VCC

ISP Sketch

First of all we must flash a sketch in the Arduino UNO to convert it into a programmer for the RPICT card.

Open the Arduino IDE and open the file Files | Examples | ArduinoISP

Make sure that Tools | Board: Arduino UNO is selected.

Upload this sketch to the Arduino uno. Click the right arrow icon in the Arduino IDE or do Sketch | Upload.

Burn the bootloader

Download the sketch that you wish to upload. Open it with the Arduino IDE.

Select Tools | Board: Arduino Uno

Select Tools | Programmer: Arduino as ISP

Then select Tools | Burn Bootloader

Flash the firmware

We recommend to flash the firmware from the Raspberrypi.

Connect the RPICT card on the Raspberrypi and use the lcl-upload-sketch.sh tool to upload the correct firmware.
