When generating your PICAXE program online using the cloud version of Blockly for PICAXE you cannot download the program directly to the PICAXE chip. This is because web browsers do not allow online websites to access your USB/COM port for security reasons. Therefore the online Cloud version of Blockly simply saves onto your computer an ‘.axe file’ which is a compiled version of your PICAXE program.
This PICAXE Downloader App, because it is installed separately as a standalone program, can then open this .axe file and download it to your PICAXE chip via the AXE027 USB cable.
Note that you do not need this app for any other PICAXE software that is installed directly on your computer (PE6, AXEpad, Logicator etc.) as they can already program the PICAXE chip directly.This app is only required when using the cloud (web) version of Blockly for PICAXE. However you may also choose to export an .axe binary file from PE6, this is useful, for instance, you want to allow someone else to program a device with your code but do not want to share your original source code file.
The PICAXE Downloader is a free app and can be installed on Windows, Mac, Linux and Chromebooks.
Note that if using the AXE027 PICAXE cable on Mac or Windows you will also need to install the AXE027 driver. Instructions for Linux or Chromebooks are here.
Using the Downloader App
- Click the ‘Open’ button and select the desired .axe binary image file
- Select the correct COM port for the AXE027 download cable
- Connect your PICAXE board and power and then click ‘Program’
