LPC17xx/40xx Event Monitor/Recorder example

Detailed Description

Example description
This example describes how to use Event Monitor/Recorder Block to track event occurs on input pins.

After initialize RTC, set the current time for the RTC. When an event occurs on an input channel, an interrupt is generated. The first and last timestamp of the event is printed out.

Special connection requirements
Connect desired event input channel pin to GND/VCC to generate events.
Event Input pins:
Channel Pin EA
0 P0.7 J5.17
1 P0.8 J3.19
2 P0.9 J5.18
