Guys,
I following this example to get the rAdafruitSSD1306 - OLED displays working with a wemos D1 mini.
https://www.b4x.com/android/forum/threads/radafruitssd1306-oled-displays.68906/
I know that the device is wired properly, I2C wise, as I can scan the I2C address fine (0x3C). I have simplified the Clock example from the thread above which now looks like:
Unfortunately the only result I could get is the screen displaying several (hundreds) white dots randonly placed. I have also replaced the device as I thought the first was just broken but the new one I got today behaves the same way..
Am I missing something ?
thanks!
