Testing Firmware Needed

[biomurph]

Initial Issue Post

There is a need for testing the BTE units during production. The test should be simple, and result in a go/no-go result.

Proposed Requirements

The test needs to be performed at different stages of the assembly process.

1. Upon connecting the Flex PCB
2. Upon fitting Mic Carrier
3. Upon 1/2 Clamshell assembly
4. Upon complete Clamshell assembly

Pseudo Code

1. Generate a 1kHz tone on the speaker output with a small speaker
2. Connect with the PDM microphones and patch them to inputs
   • Monitor the PDM inputs for the 1kHz tone
3. Generate a 1kHz tone on the RIC output
4. Connect the RIC to the MIC input of the Tympan
   • Monitor the Tympan MIC input for the 1kHz tone

Is this a sufficient to maintain quality?

Until there is assembly specific testing firmware, @eyuan-creare has proposed using the example sketch EarpieceManualMixing_wSD.ino. This will provide the following test signals

• Front and Back earpiece mic will present on the Tympan speaker output. Verifiable with headphones
• RIC will output the audio that is picked up from the earpiece speakers. Verifiable by listening to RIC

@eyuan-creare
I just discovered this example in the Library !!
OutputTone_wEarpieces.ino
I will use it to verify the RIC functionality as a first step, then use the EarpieceManualMixing_wSD.ino to test microphone functionality during assembly.
