fix of readout, gain, grating

[adriente]

Hi,

Aim of the pull request

We have a Shamrock spectrometer from andor equipped with a Newton EMCCD in the lab that we cant to control using PyMoDAQ. We couldn't modify the horizontal readout speed and the gain of the EMCCD. There were only 2 gratings accessible from PyMoDAQ even though the spectrometer has three gratings.
This pull request fixes those issues and it was tested on the described hardware.

Gratings issue

I modified the ini_spectro function so that the name of each grating is different so that all gratings appear in the parameter list.

Gain issue

I added a new parameter in the settings and modified the commit_settings accordingly. The parameters bounds are updated in ini_camera.

Horizontal readout speed (HSSpeed)

To control HSSpeed, the type of camera (EMCCD or conventional) has to be set. Additionally there may be several Analog to Digital (AD) channels configured, so the AD channel index has also to be specified. The number of available AD channels and the CCD type are set at init using init_AD_channels. These values are now stored in the AndorSDK object.

In PyMoDAQ, the parameter contains a 'AD channels' group which contain a 'ad_channel_#' list for each available AD channel. Each list displays the avalaible horizontal readout speeds.

To be done soon

• Implement a way to manage units for readout speeds
• Clean the functions that are not properly using AD channels

To be done later

• Fully fix the AD channels issue.
• Implement gain control for different CCD.
• Implement the advanced settings for control over CCD gain.
• Implement control over Vertical readout speed too.

I made a mistake when using SetHSSpeed, I was giving a string as input while it needs a an int. It is fixed in the second commit.

That's why you have to test it for real on the device, let us know here when you're done
