TIDA-00254: LED current(brightness) setting, with DLPLCR4500EVM

Part Number: TIDA-00254
Other Parts Discussed in Thread: DLPLCR4500EVM


I am using the reference design TIDA-00254, with DLPLCR4500EVM.

I can set the led current value to all 255 with DLPLCR4500GUI-3.1.0 and no problem.

When using the reference design, I set the brightness of the projector at config/config_projector.txt (LCR4500_PARAMETERS_LED_CURRENT_RED/GREEN/BLUE).

I found out that whenever I set the value to more than 160 (170, 200,...) and perform scanning, the DLPLCR4500EVM will crash and restart.

Is this normal? How can I fix it?

By the way I was trying to scan black objects from a distance, should I just add extra lights?
