MicroAPRS Firmware Flash Instructions

The batch and script files in this folder use AVRDUDE to flash the binarys of MicroAPRS to the Arduino Pro Mini. Originally I had the MicroAPRS binarys in this folder as well as a copy of AVRDUDE. However that is bad practice (and prob against their licenses) so I have removed them. I am leaving this batch file here so that it can be used if needed. The MicroAPRS repo has good information on how to flash it anyway.

Windows

  • Modify the install-windows.bat batch file to suit your configuration.
  • Using device manager set PORT manually by checking what your FTDI cable shows up as:

- Download the latest version of avrdude from [here](https://github.com/avrdudes/avrdude/releases) and extract it to the same folder as the install-windows.bat file. - Run the batch file by double-clicking on it:

MacOS

  • Modify the install-macos.sh script to suit your configuration.
  • Using the blowe command in terminal set PORT manually by checking what your FTDI cable shows up as:
    ls /dev/tty.*
  • Make the script executable:
    chmod +x install-macos.sh
  • install avrdude using brew:
    brew install avrdude
  • if brew is not installed, you can install it from terminal like this:
    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/HEAD/install.sh)"
  • download the MicroAPRS precompiled binary file from here and place it in the same folder as the install-macos.sh script.
    • microaprs-5v-ss-latest.hex for the 5v Pro-Mini
    • microaprs-3v-ss-latest.hex for the 3.3v Pro-Mini
  • Run the script from terminal:

Hint: If avrdude complains about not being able to sync, you may need to manually hit the reset button on your Arduino Pro-Mini.
