Running on your breakout board, the 64x48 display CFAL6448A-066BW, runs perfectly. In our circuit, is running dimly, and seems to be putting a lot of noise onto the SDA and SCL lines. They show a square wave and fall short of the VCC rail. If we drop the value of the pull up resisters the display brightens a small bit. With the display out of the circuit these lines are fine and communication with other I2C devices works just fine. This must I sure be a symptom of something else not working or connected correctly. Any thoughts on what we are doing wrong would be appreciated.
Here is the circuit diagram. I notice on our implementation CS is connected to ground, while on the breakout board it is left floating?
We fold the the flexible printed circuit over so the pin direction is reversed!
Looks like I might have BS1 and BS0 swapped around?
