Getting Started Using the TCA8418E-EVM
5.5.1
Evaluating the TCA8418E EVM without the LaunchPad
1. To power the TCA8418E-EVM without the LaunchPad, apply a 3.3-V, 100-mA power supply to TP1
(VCC pin). Although 3.3 V is preferred, the voltage range can be from 1.65 V to 3.6 V.
2. Attach an external microcontroller to J3 to provide SCL and SDA inputs for I2C. Keep in mind that SCL
and SDA are pulled up to VCC on the TCA8418E-EVM through 4.7-kΩ resistors. Therefore, using the
same power supply for the microcontroller and the TCA8418E-EVM is recommended.
3. Use the built-in 3x3 keypad on the TCA8418E-EVM or use J5 to attach an external keypad. If attaching
an external keypad, the KP_GPIO registers (0x1D, 0x1E, and 0x1F) should be configured to
accommodate the additional keys.
5.5.2
Evaluating the TCA8418E EVM with the LaunchPad
After completing the steps in Section 5.2, launch the TCA8418E-EVM software. The screen will look like
Figure 13.

5.5.2.1
Using the Key Press Matrix Display
Connect the TCA8418E-EVM and launch the GUI. The key press matrix display will only work when
KE_IEN (0x01, bit 0) is set to 1. By default, key event interrupts are enabled because KE_IEN (0x01, bit 0)
is set to 1 and the key press matrix display responds in real-time to key presses and releases. Press the
middle button (SW12) on the TCA8418E-EVM and observe the feedback from the display (Figure 14).
Figure 14. Key Press Matrix Display While Holding Down the Middle Button (SW12)
Releasing the key causes the grey box to become white again.
5.5.2.2
Main Configuration and Input Registers
Figure 15. Main Configuration and Input Register Display
The main configuration and input registers are the registers most likely to change while operating the
TCA8418E-EVM. For this reason, they are more prominent on the GUI.
The CFG register contains the interrupt enable bits for different types of interrupts.
The INT_STAT register contains the actual state of each type of interrupt.
The KEY_LCK_EC contains the lock status, can be written to lock the keypad, and counts the number of
key events (in the 4 least significant bits).
KEY_EVENT_A is the top of the first-in first-out (FIFO) stack that records key presses and releases.
KEY_EVENT_A is read automatically when KE_IEN = 1 and a key has been pressed or released.
Whenever one of these four registers is read, the main configuration and input register display updates to
show the newly read value of those registers.
The Read registers 1-4 every second checkbox causes the TCA8418E-EVM GUI to start a timer that will
read registers 1 through 4 every second. The read takes 100 ms. This feature shows how KEY_EVENT_A
and KEY_LCK_EC change every time the registers are read. Disable the KE_IEN bit before checking this
box; otherwise, nothing appears to occur in registers 3 and 4.
