DOGM128 Backlight

I succeed to get the DOGM128 Display running. I tried a lot of things until I found a tantal capacitor soldered in wrong polarity.

 

So I get now the "Ready"-Message on my display, but the backlight is not on. Should it be on without a special command, or how can I switch it on?

The backlight LEDs are directly connected between Vdd (anodes) and B- (cathodes), there is no SW control for the brightness.

 

Did you already try to adjust the "Luminance" trimpot P1 on the MBHP_CORE_LPC17 module?

 

Best Regards, Thorsten.
