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)
