3 :relevant-api: sensor_interface
5 Get analog comparator data from an NXP MCUX Low-power Analog Comparator (LPCMP).
10 This sample show how to use the NXP MCUX Low-power Analog Comparator (LPCMP) driver.
12 In this application, the negative input port of the LPCMP is set to 7 which
13 means the input voltage comes from the LPCMP internal DAC, the reference
18 The positive input port is set to 0, the user needs to check the reference
19 manual and board schematic to confirm which specific port is used and can
20 connect an external voltage to that port and change the input voltage to

8 ESP-WROVER-KIT features the following integrated components:
10 - ESP32-WROVER-E module
11 - LCD screen
12 - MicroSD card slot
14 Its another distinguishing feature is the embedded FTDI FT2232HL chip - an advanced multi-interface
16 without a separate JTAG debugger. ESP-WROVER-KIT makes development convenient, easy, and
17 cost-effective.
