Hi I have mentioned this under access denied com3 but I can fix the access denied by chmod. The blank screen is still with me. I have two T-beam radios now and both show the same problem working on 0.6.4. Instead to seeing:
I2C device found at address 0x34 axp192 PMU found I2C device found at address 0x3c ssd1306 display found
on boot I only see the first two lines. No mention of ssd1306 or any display. Once I managed to see this but still I did not get to a live screen. So this could be a faulty screen, VCC and GND look correct but it could be something else. Or it could be that they need to be soldered in place and when I have done that I have accidentally connected across the pins.
If anyone else sees this same issue I would be interested in their solution. Thanks!
