MC3672 3-Axis Accelerometer
The difference between
could be worked on I2C interface by changing R1 value to 100KΩ and R3 value
EV3672A
to 10KΩ (for 0x4C I2C address).
EV3672B
could be worked on I2C interface (with address 0x4C) without any reworking.
Configure the bus in the MC36XX Driver accordingly when changing from SPI to I2C
interface, and vice versa (please refer to Section 3.1).
R4, R5: Install ~4.7KΩ (if no other pull-up installed) as the pull-up for I2C interface.
NOTE: It is recommended not to install more than one pull-up per I2C bus.
R6: Install ~4.7KΩ pull-up resistor if sensor interrupt pin is set to open-drain. (DNI by default)
R7: The driving current of sensor can be measured by putting an ammeter in place of R7.
The physical location of the resistor is in the diagram in Section 1.3.
