Connect the negative lead of the multimeter to J2 or one of the four GND headers (P3, P4, P5, P6).
Connect the positive lead to test point P11. Test passes if Voltage measured is between 6.7 V and 7.3
V.
Remove the 3.3 V applied to pin8 and pin9.

Test Voltage 5
Connect Pin6 of header P9 to Ground. Connect the negative lead of the multimeter to J2 or one of the
four GND headers (P3, P4, P5, P6). Connect the positive lead to test point P11. Test passes if Voltage
measured is between 1.8 V and 2.4V.
Remove the connection from Pin6 of P9 to Ground.

Check Resistance
Remove all connections to the EVM. Set the multimeter to measure resistance. Place the negative
probe of the multimeter on one pin of R17. Place the positive probe on the other pin of R17. Test
passes if Resistance is between 1.0 kohm and 1.5 kohm.
Repeat Test for R18and R19.

Setup for functionality
Install jumpers on the following headers: P12, P13, P14, P15. Ensure no jumper is installed on P16.
Connect the MSP430 launchpad to the board by inserting J1 of the launchpad into P9 of the EVM and
J2 of the launchpad into P8 ensuring that pin 1 of J1 matches pin 1 of P9 and pin 1 of J2 is inserted into
pin 1 of P8.
Attached the Ground of the power supply to Pin2 of J1 and 3.3 V from the power supply to Pin1 of J1.
Connect the Launchpad to your PC using a USB to USB-A cable. Launch Code composer. Launch the
TCA8424 API project debugger. Press the “play” button.
Open the Application GUI.
DO NOT CLICK ANY BUTTON UNLESS SPECIFICALLY INSTRUCTED.
Under the Select Port there is a drop down menu box which will be blank on startup by default as
shown below:
