Download: https://www.qhyccd.com/file/repository/latestSoftAndDirver/Demo/QHYCCD%20SDK%20API%20MENU_V2.6_EN_Beta.pdf SDK Demo SDK C Wrapper qhyccd_c_wrapper This is a C-language wrapper for the QHYCCD SDK. Because the SDK itself is a C++ library, direct use from languages such as C or Go is not straightforward. This wrapper solves the problem

BASIC Working Flow Single Image Capture Mode: *** First function you have to call after load SDK *** InitQHYCCDResource();***Find  device before open*** ScanQHYCCD(); GetQHYCCDId(0,id); camhandle = OpenQHYCCD(id); **** do these before InitQHYCCD  (you can Only set them ONCE after open) *** GetQHYCCDNumberOfReadModes(camhandle, numModes); // Use GetQHYCCDReadModeName if you need more detail SetQHYCCDReadMode(camhandle, modeNumber); SetQHYCCDStreamMode(camhandle,0); InitQHYCCD(camhandle); SetQHYCCDBitsMode(camhandle,16);*** do these before exposure (You can reset them anytime

Connect the camera to the lens and take two flat field pictures inside the shadowless lampshade. Try to ensure that the brightness of the two pictures is uniform and consistent, and it is recommended to use 1/3 or 1/2 of the saturation value. Here we can give these two photos any name, such as A1 and A2.   Open the MAXIm DL software, use the

QHYCCD Firmware Upgrade Instructions V1.2 (for 20220824 version and above)   1 Upgrade Procedure NOTE: 1 During the upgrade process, be careful not to power off or shoot. 2 Before upgrading, if you have previously kept an older version of the firmware upgrade tool locally, please discard it and use the new firmware update tool (20220824 version) instead.       1.1. Use the USB3.0 cable to

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

In WINDOWS application development, QHYCCD provides a real-time output through DEBUGVIEW software in order to facilitate developers to call QHYCCD SDK to write their own programs, verify the parameters of incoming and outgoing SDKs, and verify that the calling steps are correct. The method of debugging information. In the QHYCCD SDK development package, there is a directory called SDK with output debug information output. If

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”,
