To be able to control the camera from AXIOM Remote, a communication channel has to be implemented, this includes extending AXIOM Remote firmware, as well as control daemon. Main preference is UART via USB, RS232 or RS485

Goals:

• Add UART/socket communication to the control daemon
• Extend the daemon with parameters which can be controlled by the firmware later
• Add UART communication to the AXIOM Remote firmware
• Implement additional menus to control previously added parameters

Prerequisites:

• Embedded systems basics (we use a Microchip PIC32MZ CPU) - Full Manual: https://www.alliedelec.com/m/d/1e5e0c2adda09fc1913391ccd4594515.pdf

Language Skills:

• C for PIC32 firmware
• C++ for control daemon

Difficulty: Medium

Mentors: Andrej (main mentor), Bertl (backup/co mentor)

Notes:

• The PIC32 handles the low level stuff and the electrical interface
• On top of that to use UART over USB (or HID, which might be interesting too) on the PIC32, the USB stack needs to be implemented.

• So the suggested steps would be something like:
  • plan what PIC32 based device(s) are realized via USB - any development board with the PIC32 works
  • make a test setup with Harmony (Microchips USB Framework) to see how/that it works
  • adapt this to work without the Microchip libraries/framework (see Documentation below)
