Hardware requirements

  • Mini/micro USB cable

  • MCX-N9XX-EVK board

  • Personal Computer

Board settings Positive INP0 J4-1(P4_12). Positive INP1 J20-18(P4_13). Negative input channel J4_3(OPAMP0_INN) connects to GND. OPAMP output pin: J20-20(P4_15)

Prepare the Demo

  1. Connect a micro USB cable between the PC host and the CMSIS DAP USB port (J5) on the board

  2. Open a serial terminal with the following settings (See Appendix A in the Getting started guide for a description of how to determine serial port number):

    • 115200 baud rate

    • 8 data bits

    • No parity

    • One-stop bit

    • No flow control

  3. Download the program to the target board.

  4. Either press the reset button on your board or launch the debugger in your IDE to begin running the demo.

Running the demo

OPAMP TRIGGER MODE EXAMPLE!

1. Connect INP0 and INP1 to different levels.
2. Monitor OPAMP output with an oscilloscope. When OPAMP receives a trigger signal, it will switch to different output voltages.
