I would like to use it with a spark core. Do i need pull up resistor for i2c?
Is there a schematic for this anywhere? I'm trying to use it with a Grove Shield on an ST Micro Nucleo board. I've got it hooked up to my scope and am watching the i2c bus. One of the questions is the address for the LCD and RGB driver are shifted in t
Replying to my own post but I solved my issue. To use this display with the ST Micro Cortex M series you set the GPIO's to Open Drain, and tie them through 10K pull up resistors to 5V. Then the display will respond correctly (the ST inputs are 5v toler
