2 ASSEMBLY AND TEST
Please note that the SPI and I2C interfaces cannot both be active at the same time as
the clock (SCK) and data (SDA) are shared between the two protocols.
2.1 I2C INTERFACE
The EV3479A evaluation board can be easily wired to any microcontroller. This example
shows a typical Arduino DUE platform. For other microcontrollers, be sure it has I2C with
repeated-start support, then port the code. Please refer to the illustration below to connect the
related pins.
•
Connect
DVDD
to the power supply,
3.3V
. (WARNING: attempting to power the part at
a voltage exceeds the maximum rating of 3.6V is likely to damage it.)
•
Connect
GND
to common power/data ground.
•
Connect the
SCL
pin to the I2C clock
SCL
pin on your Arduino.
•
Connect the
SDA
pin to the I2C data
SDA
pin on your Arduino.
The
MC3479
has a default I2C address of 0x4C and it can be changed to 0x6C by tying
th
e SDO
pin to VDD.
