AIOC and SVXLINK #86

Open F8ASB opened 1 week ago

F8ASB commented 1 week ago

Hello all,

I'm trying AIOC with Svxlink repeater software, AIOC is detected and audio level on alsamixer are available and /dev/hidraw0 is present on my Raspberry Pi.

For RX config is for a CM108 and SQUELCH(COS) detection on VOL_DW pin 48. HID_DEVICE=/dev/hidraw0 HID_SQL_PIN=VOL_DN SQL_DET=HIDRAW

For TX config: PTT_TYPE=Hidraw HID_DEVICE=/dev/hidraw0 HID_PTT_PIN=GPIO3

I have this error: Wed Sep 11 10:04:09 2024: ERROR: unknown/unsupported sound chip detected... Wed Sep 11 10:04:09 2024: ERROR: Squelch detector initialization failed for RX "Rx1" Wed Sep 11 10:04:09 2024: ERROR: Could not initialize RX "Rx1" Wed Sep 11 10:04:09 2024: ERROR: Could not initialize Logic object "SimplexLogic". Skipping...

Have you an idea to resolve this problem?

Maybe HID_SQL_PIN=VOL_DN isn't correct for AIOC.

Hi! I am not familiar with the software. From what I can tell, I would guess that the last 3 errors are a result of the first error. And the first error is probably related to the fact that SVXLINK checks VID/PID of the given hidraw device, to detect what driver it needs to use (e.g. CM108). It doesn't recognize the AIOC's own VID/PID although the AIOC would be compatible to the CM108 chipset.

Currently, there are two ways to solve this particular problem. Either use the preview release and a python script to configure the AIOC for a different VID/PID. However this does currently not work on Windows. https://github.com/skuep/AIOC/issues/46

The second way is to use the firmware of G1LRO, that has baked these changes into the firmware. https://github.com/skuep/AIOC/issues/61 https://g1lro.uk/?p=676

In both cases, the VID/PID pair of the AIOC is changed so that it looks (almost) like a genuine CM108 chip to the computer. So it comes with all the caveats that you can read in those issues.

Hi!,

Thanks for your reply.

I'll try and report back on this thread.
