Before using Ardhat, make sure you have upgraded to the latest supported version of your host operating system and apps.
If using Ardhat on a Raspberry Pi, see this guide on the foundation website.
Updating the bootloader
If required, this bootloader and app can be replaced using the following procedure:
- Download the ArdhatCloner Sketch from here
- Using the instructions provided in the Sketch, connect an Arduino or compatible processor to the Ardhat ICSP (you can use some simple jumpers as shown in the image below)
- Install the ArdhatCloner sketch on the Arduino.
- Restart the Arduino, and the ArdhatCloner sketch will install the latest bootloader and factory default app from the included data.h
Preloading custom apps
If you want to load a custom app in place of the factory app, use hex2c.tcl which is also included in the ArdhatCloner repository. This handy utility, from JC Wippler of Jeelabs fame, creates a single data.h file from multiple .hex files, which can be used to replace the default data.h
