Hi All,
What PINs does the OLED screen use?
Can it use arbitrary pins or does it need the Hardware Interrupts or Hardware Serial pins?
Ie - if I only have a few digital pins, can it just use those or does it need special ones?
This would be on a Moteino Mega using Radio and Flash - ie something that already has many pins committed. My project already uses both Hardware Serial ports as well.
Sorry - I cannot seem to find anything online that describes concisely.
Are you referring to the OLED that was part of the MotionMote kit?
That has 4 pins: GND, Vcc, SCL SDA. So it uses the I2C pins on the MEGA.
If you check the MEGA pinout (https://lowpowerlab.com/moteino/#pinoutMEGA) that would be pins 16 & 17.
VCC can be supplied from the "3.3v" pin since the OLED only needs up to 10-15mA.
Thanks Felix exactly what I was looking for!
