Arduino Uno

[Marijonas Tutkus]

Hi everybody,

We are designing a new TIRF scope with a piezo-Z objective stage and a dedicated 1 axis  controller from the piezoConcept. I was wondering whether the Linear Light Array on the TSL1401CL-adapter board would work in combination with Arduino Uno and piezo controller from piezoconcept?

H Marijonasi,

Yes. The pgFocus firmware has all the code necessary just to run the TSL1401CL, which you are welcome to use. pgFocus controls the piezo with a voltage signal, how will you control your piezo controller?

I did create a pgFocus shield design but never tested it, but you can connect a TSL1401CL directly to an arduino.

Ngā mihi,

That sounds great.

The piezoConcept's controller provides several options: 1) voltage control  (0-10V, -5V/+5V, or -10V/+10V), 2) the USB interface, 3) manual.

I would prefer the USB interface, which allows to control the position of the z-piezo stage using a computer.  Also it comes with 4 TTL outputs (can be configured as inputs). One of them is used for controlling the Z-piezo stage. So the remaining may be used as DAC (to send analog voltage) or ADC (0-10V).

Hi Marijonas,

I think that is a great idea, and one I was going to implement in the pgFocus device adapter for micromanager, if I have ever get the time,... use the linear light array to position a "z-stage", rather than directly act on a piezo via voltage. It would be less responsive, but should be fine for most focus changes/corrections. Since it has been years...I am not sure if I will ever get to it. But, if you need help, please let me know.

Hi Karl,

Sorry, I missed your last email, and noticed it only now.

I also think that the fast response is not that important. The overall stability is more important to me.  I would love to hear your suggestions on principles how to build the system. Maybe it is enough to use the piezoconcept's 1-axis USB controller (http://www.piezoconcept.com/controler/   http://www.piezoconcept.com/wp-content/uploads/2017/03/ANALOGUE-CONTROLLER-SINGLE-AXIS-0to10V-2Amps.pdf), if there is a way to connect the linear light array directly to it. But it seems to me that it is impossible to avoid using Arduino or similar to interface piezoconcept's USB controller with the linear light array.

BTW., I will use the FOC-100 piezo objective stage :  http://www.piezoconcept.com/all-products/foc-100/

Warm regards, Marijonas
