RobinoScan Strobe / Flash System

From your system diagram, assume you continue to use the PWM DAC? or are you controlling directly to TP3-PWM. If the later, confirm that R14 was removed.

Yes I’m still using the DAC

@PM490

If that is the case, given that the 1mS would be within the range for the PWM (100 Hz to 10 KHz), you may be able to create the flash by removing R14 and connecting the 1mS pulse to TP3.
If the above works, then you can adjust the balance of the colors by changing VIADJ.
WARNING: R14 is listed as Zero Ohms, a short, so do not use the TP3 without removing it.

I will try this tonight and report back! Thanks very much for looking into a solution for this setup.

Please do not take as a definite answer, it is hard to make an exact determination since I have not previously used that TI IC. Suggestions are based on the information on the datasheets.

No worries and at this point I’m responsible for any explosions Only thing is I hate removing these little resistors, I had to change 6 of these on the pico buck to get to 1A per channel. Thankfully I now have a little more experience.
