Dear Tech Support,
I recently purchased P/N CLP6C-FKB-CM1Q1H1BB7R3R3CT-ND. I have written code and use PWM to output various colors.
I did the calculations using my voltage supply and Vf to determine the proper resistors for the R, G, and B LED’s.
Prior to flashing my code, I connected the LED to my power supply with the resistors and found R to be very bright, but B and G were very dim.
So had had some lower value resistors laying around, not the exact values that I will eventually need, soldered them into my board, flashed my microcontroller with the code that I wrote, and used PWM at about 20%
When I turned on R with 20% duty cycle, the light was very bright. (255, 0, 0)
When I turned on G with 20% duty cycle, the light was very bright. (0, 255, 0)
When I turned on B with 20% duty cycle, the light was very bright. (0, 0, 255)
When I started using combinations of RGB, white was perfect, so was yellow, and a bunch of other colors.
ONLY when the color is BLUEish (pale blue, purple, etc…) one of the LED’s in the module blinks. I cannot tell which one is blinking because I cannot stare into the LED, and I cannot figure out why only one is blinking.
Do you have any ideas?
