Final tests: 1. Use the second Arduino/Bylund shield in place of the first one --- perhaps first boards are faulty. Result: With the 24pt original text size in this sketch, display froze within 20 seconds of start up. 2. Replace the installed Bosch 4.9 sensor with a second --- perhaps the first Bosc...

Further testing... Freezing being a possible memory issue, the display font in Bylund's sketch was reduced from 24pt to 12pt. "Used space" dropped from 80% to 70%. This resulted in a distinct increase in display stability but it's still not operating consistently. Flowing data was sufficie...

Hi Christian, Background: Have dual Bylund system set up with all hardware purchased from you---Arduino UNO, Shield, 4.9 Bosch sensors. Data is displaying on a .96" OLED. There was an issue with the icons cutting off on the far right and the cut offs showing on the display's far left. This was ...
