SDK version 2021.7.6 later supports the 32bit image data accquirement function. This function is useful for the 16bit cmos like QHY600,QHY268,QHY411, QHY461. When 2*2,3*3,4*4 binning the data range will become 18bit, 19bit and 20bit. Since it exceed the 16bit range, we add the 32bit data transfer function for these cameras. How to get to know the camera support 32bit image? The IsQHYCCDControlAvailable(qhyccd_handle *handle, CONTROL_ID controlId)

This document will introduce the APIs for these function. How to know if supported Before you call the temperature API. You need to use the IsQHYCCDControlAvailable API to check if the camera supports it. If QHYCCD_SUCCESS returned,

From the Version 2019.2.15 and later, The QHYCCD add the ReadMode APIs. Because the mode change will change the whole define of the basic image X, Y. And the memeory allocate. To compatiable with all exist software which use the QHYCCD

C# wrapper Under C#, you need to call the QHYCCD API from qhyccd.dll by dynamic api calling, by using the DllImport. The following wrapper code is taken from our C# project for QHYCCD ASCOM Driver. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Runtime.InteropServices; using StructModel; namespace ASCOM.QHYCCD {     class libqhyccd     {         [DllImport(“qhyccd.dll”, EntryPoint = “InitQHYCCDResource”,
