TOPIC: INDI/Linux driver for the QHY Polemaster, developers needed.

INDI/Linux driver for the QHY Polemaster, developers needed. 6 days 12 hours ago #16271

Thanks Jasem!

I tested the new build and initially had issues:
- needed GCC 5.x for qhy driver
- my polemaster was not receiving the firmware blob upload and thus was not being recognized by indilib

My polemaster is showing up as Bus 001 Device 006: ID 1618:0940
After loading firmware, it shows up as 1618:0941. I had to modify 85-qhy.rules to include 1618:0940. Disconnecting and reattaching the PoleMaster after making this change resulted in the firmware getting loaded and the device being recognized by indilib.

I found that I was getting about 1FPS while framing. I guess this is to be expected since I am using an Intel Edison which is a dual-core Intel @500MHz, plus I am connecting via WiFi.

I did notice a message about SQM while starting the server which I didn't notice prior to loading the QHY module. Is there perhaps plans to use the PoleMaster as a SQ Meter, because that would be a cool use for the device.

I attempted to enable compression and got about the same framerate from the camera... it turns out that the CPU was limiting.

I compiled on my pine64 and connected via GigE. Framerate was about doubled, however it appears that compression is single threaded.

I left the indi server up for 2 hours why grabbing frames continuously, and I did not experience issues.

Thanks for the test, I will relay this to QHY. I updated the rules file to fix the issue. For SQM, it can be done if someone works on the math and algorithm. I have a separate SQM LE device and I wanted the SQM reading to be in the FITS header.

The camera looks to take images just fine in INDI, is there something specific we should be testing out?

I managed to use the Polemaster as a guider in EKOS last night with my rPi GPIO ST4 implementation. I did run into an issue while attempting to use it for imaging. It appears to have problems when exposure times exceed 45sec or so, where images returned were just black and contained no data. It could have been a software issue on my end, I'll test again this evening with a pristine installation of INDI.
