LPC 845 CONTROLLER TIMER & PWM

Arularasan — Tue, 30 Apr 2024 05:50:29 GMT

why there are two distinct ways to manage timer and PWM functionalities in this microcontroller

Chapter 20: LPC84x Standard counter/timer (CTIMER)

Chapter 21: LPC84x SC Timer/PWM.

1.Both are same or Not ?

2.why these tow timers ?

3.is there any use of these both ?

4.give example for this both ?

HI Arularasan

SCTimer is more flexiable than CTimer

We can use SCTimer to simulate some peripheral like UART, or use SCTimer to control BLDC

Here is SCTimer cookbook:

Here is SCTimer applications:

MCUXpresso SDK includes both SCTimer and CTimer demo codes

We can download here

Hope this helps.

Have a nice day,
