Hi Torsten, There is a #endif missing at the end of Test5BackLight.cc. The backlight seems to work well. When I switch on the device this is what I see: light on (default) light off (5 s) light on (5 s) light off (5 s) light on (5 s) Text begins. But the feedback in debug mode is not correct. I get: backlightstate: 0000 : off ? backlightstate: 0000 : off ? backlightstate: 0000 : off ? backlightstate: 0000 : off ? With the running text the contrast is bad. I agree with you that this is a hardware problem. I have a 16x2 characters display that apparently is not compatible with 1-line operation mode. The rest works fine. Best wishes for 2015. Pepe | ||
