96x64 White OLED with I2C/SPI interface
---------------------------------------
The OLED display can be connected either to the SPI-bus or the I2C-bus.
Jumper Settings:
- For the SPI interface (default), insert jumpers in J42, J43, J45 pin1-2
and J46 pin 1-2.
- For I2C interface, insert jumpers in J45 pin 2-3, J46 pin 2-3 and J47.
In either case insert a jumper in J44 in order to allow PIO1_10 to control
the OLED-voltage.
Jumper Signal Control:
J42: Short: SPI Open: I2C (Default: inserted)
J44: Allow control of OLED voltage (Default: inserted)
PIO1_10-------->J44 ---------->FAN5331
Common Reset:
