Control/Dimming Advice Required on DAC

[vijithamca]

Dear All,
I have Galvo with XY Control board purchased from LASERPIC.
Galvos, Scanner, Scanning, laser show,laser projector at laserpic

Galvos, Scanner, Scanning, laser show,laser projector at laserpic

The board required DAC signal to be sent and I have built my own DAC using DAC chip - AN7528JN and PIC Controller. I can get DAC output results as required. I can also control the movement of the X & Y galvos from my controller based on the output that I give.

But I am confused on how to generate patterns and run it out. After a little search I learned about ILDA format and there is no clear idea for me on sending the DATA to the control boards from my PIC controller.

Can anyone please HELP me and give me some advice to send the data to the control board from my PIC controller to control the galvos and draw patterns in the standard procedure. I just need to know the format in which the data has to be sent out.

PLEASE ADVICE.

Thanks in advance.

If it's the case that your pic is sending the right signals, then, if I understand the problem, you are looking for a way to store and replay a sequence of data points to the pic.
Could not a subroutine be added to your program to sequentially read a table of some sort that had your x, y, and wait time or 'loop to' information as rows and send that to the DAC portion of the pic? Might require a second pic, I don't know. The table might be in comma delimited text so you could edit it easily.
