Schematic 4: Controlling settings via microcontroller
Operation with variable settings via I²C-Interface
The mp6-XOEM can also be operated using the I²C-Interface. Using this interface all the features of the chip can be
accessed. The functionality and procedures are identical to the mp6-QuadOEM. A complete interface and protocol
description can be found in the manual of the mp6-QuadOEM on our download page.
To activate the I²C-Interface the onboard processor has to be deactivated by tying the reset pin to Ground. Select a
desired slave-address connecting pins A0 and A1 to either VDD or GND and interface the chip through the I²C-pins
SDA and SCL. Both need an external pullup resistor (47K recommended) tied to VDD. (There are no pullup resistors
onboard the mp6-XOEM)
