I think I can throw away my Meade LPI if I have this. :D

The camera works in two exposure mode.
One is frame exposure mode.
One is electric rolling shutter mode.

For guiding , the frame exposure mode is recommand.

The frame exposure mode's exposure time depend on the readout interval time between two exposure.So the min exposure time is 1/15sec. The longest time is no limit.

For moon ,sun etc bright object.The rolling shutter mode is recommand.

Visual Basic DLL calling method

1.copy the astrodll.dll into windows/system32 folder
2.open a new vb project
3.Add the following declare into the codes

Private Declare Function openUSB Lib "astrodll.dll" _
               (ByVal PortId As String) As Boolean
               
Private Declare Function openUSB Lib "astrodll.dll" _
               (ByVal PortId As String) As Boolean
               
Private Declare Sub cmosReset Lib "astrodll.dll" _
               (ByVal PortId As String)
               
Private Declare Function sendI2C Lib "astrodll.dll" _
               (ByVal PortId As String, reg As Byte) As Byte
               
Private Declare Sub readUSB2_OnePackage Lib "astrodll.dll" _
               (ByVal PortId As String, ByVal P_size As Long, ByVal exptime As Long, ImgData As Byte)
               
Private Declare Function sendGuideCommand Lib "astrodll.dll" _
               (ByVal PortId As String, ByVal GuideCommand As Byte, ByVal PulseTime As Byte) As Byte





sample codes:

'check if there is USB connection when form start
Private Sub Form_Load()
Form1.Caption = openUSB("EZUSB-0")
End Sub

'send CMOS RESET COMMAND TO CAMERA
Private Sub Command1_Click()
cmosReset ("EZUSB-0")
End Sub

'send one register to camera (0x35,the global gain ,set to 0x06ff, the maxium for highest value for guiding)

Private Sub Command2_Click()
Dim reg(0 To 19) As Byte
reg(0) = 0
reg(1) = 53
reg(2) = 6
reg(3) = 255

sendI2C "EZUSB-0", reg(0)
End Sub

'send a pulse guide command. (Normal statu is 1111, active statu is 1110,one pin output a low level guide pulse ) time is 2*2ms

Private Sub Command4_Click()
sendGuideCommand "EZUSB-0", &HEF, 2
End Sub

these codes is verified at VB6.0

Note: For the calling readUSB2_OnePackage, there is some problem of define the big array,not passed.I am looking for the reason.

Dear Mr.Acanicio

It my fault to make a mistake forum operation

Here I remeber part of the question you mentioned.

1.For the subframe size and postion
2.For the rolling shutter
3.For the operation of the SendRegister command

Dear sir,

Yes, no problem !! Here are my questions again (actually they were in 2 messages) :

My name is Axel Canicio.
I am studying the SDK for your 1.3MP CMOS Camera With Guide Port and I would
like to ask you a few questions.

The camera is capable of capturing a sub-frame.
1 - Is the sub-frame's size free ? I mean for example, if I want to capture
a region of 21*73 pixels, does the camera accept it ? Or does the camera
have pre-defined region sizes (i.e for example 160x120, 320x240, 352x288,
640x480 etc.. ) ?

2 - Where is located the sub-frame on the CCD matrix ? Is the start of the
region always on the top left of the matrix ? Or can I choose the region's
top left corner (example. X=27,Y=100)

3 - How can I switch between "rolling shutter" mode and "frame" mode ?.
 I did not find a function for it.

Can you please give more explanations on how to set the gain and other camera settings please ?
You say :
<<
send one register to camera (0x35,the global gain ,set to 0x06ff, the maxium for highest value for guiding)
>>
Is 0x35 the "Gain" identifier ? and 0x06ff the "Gain" value ?
What are the min and max value limits ? 0 and 65535 ? Or do you use a preset list of values ?

I see that you use the I2C register, but I do not understand how it works, I have seen your word document "CMO planetary dll.doc"
but do not understand what you mean by
<<
Group index0: write a single register.
Group index1:write 9 register the same time.These register is effecting the timing
Group index2:write 5 register the same time.These register is effecting the gain.
>>

What is "timing" ? Is it the refresh rate frequency ? Or is it the time between exposures ?
Can you give a example for using the timing ?

In the following line :
<<
Group index2:write 5 register the same time.These register is effecting the gain.
>>
you say that you write into 5 registers, but in your example :

<<
Private Sub Command2_Click()
Dim reg(0 To 19) As Byte
reg(0) = 0
reg(1) = 53
reg(2) = 6
reg(3) = 255
sendI2C "EZUSB-0", reg(0)
End Sub
>>
you only write 4 values  : Regs 0,1,2 and 3

Where is the value #5 ?
Or maybe I got it wrong ?

Sincerely
Axel Canicio
