[approved] Logic Analyzer for RS232 interface debugging on MicroStrain 3DMQG7

Topic:

Saleae Logic 8 to debug RS232

Proposal type:

Hardware , Software , Other : _________________

Description:

I would like to request funding for a Logic 8 in order to enable my development of the External AHRS work. I currently have one of the cheap $20 logic analyzers, but it does not work with RS232.

I am unable to debug RS232 currently, and it is a hindrance to debugging issues with the 3DMGQ7 driver. I send the bits in the API to the device on TTL logic, but it’s unclear if the logic level converter is working, there is a bug in my protocol, my wiring is broken, or the AHRS is not behaving according to the API. A logic analyzer would help me pinpoint issues quickly.

Planned amount $$ (USD):

$515 USD ($500 + $15 shipping)

Estimated time for completion:

Continual Usage for diagnostics

Thanks! I’ve ordered the hardware and requested funds from the ArduPilot paypal. Cheers!

RS232 debugging is now working. This is immensely helpful. I am very grateful for the ArduPilot funding committee to support this project.
