ZWO ASI Camera unable to use minimum exposure

[aaronwmorris]

Describe the bug
I am not sure if this is a python, ZWO, Indi, C, or ARM bug. The minimum exposure for the ASI290MM is 0.000032 but if that exposure is set, the camera returns an error. This was working in Indi 1.8.9.

To Reproduce
Exact steps to reproduce the behavior.

1. Set ASI290MM minimum exposure to 0.000032

Desktop (please complete the following information):

• OS: Raspbian GNU/Linux 10 (buster)
• Raspberry Pi 3
• Version: 1.9.1
• Python 3.7.3
• pyindi-client (git: 68803a1c51fb5aa271302a748e012cf0cee309b2)
• Tested camera: ASI290MM

indi_setprop works? Ekos?

[aaronwmorris]

Both indi_setprop and Ekos accept the 0.000032 value and the exposure is properly processed.

[knro]

Well that takes care of "INDI/C/ARM" and might be just some python issue?

[aaronwmorris]

It could be some floating point conversion error between python and swig. I will reopen this bug under the pyindi-client repo.
