The display is HD44780 compatible, however there are some minor timing differences that sometimes need to be accounted for (depending on your micro). I have replicated this with an Arduino, and ha...

We are seeing some of our customers having this problem, and is usually "fixed" by lowering the I2C bus speed to ~60KHz or less. This is an issue with the current firmware on the display and not t...

Do you have both push buttons at the bottom right of the NHDev board pushed down? Did you receive a full kit from us including the cable and FFC40 board, or did you order the items separately?

The brightness for the OLED is adjustable through software via the Set Brightness command on the SSD1305 controller, and is therefore not adjustable on the NHDev board.
