Beat Posted March 12, 2013 Report Posted March 12, 2013 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? Quote
Beat Posted March 14, 2013 Author Report Posted March 14, 2013 Please, can somebody give me an answer? Should the Backlight on my DOGM128 Display be on by default after booting the LPC17? Or how can I switch it on? Quote
TK. Posted March 16, 2013 Report Posted March 16, 2013 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. Quote
Beat Posted March 18, 2013 Author Report Posted March 18, 2013 This was it exactly! I don't knew the function of these pots. P2 is for the contrast I think. So TK, thanks a lot for your help. Quote
