Hi,

I need to configure 3 separate timers in MSP430 for delay purposes.

I need to get a delay of :

250ms
10 seconds
90 seconds

Please share a sample code that I can refer for the same.

Also I have the following requirements:

The timer should be using ACLK
It should run in UP MODE

Hello,

You could use a single timer module sourced by ACLK that does all three delays. For 250 ms period, you wouldn't need a software counter like the 10 and 90 second periods. If you're using CCS, you can find timer code examples that use Up mode and ACLK in the TI Resource Explorer. You may need to download and install MSP430Ware. There's always dev.ti.com/tirex where you can find code examples for your device too.

Another option would be to use the RTC module as described in the following Tech Note.

Simple RTC-Based System Wake-up Controller Using MSP430™ MCUs

Using the Real-Time-Clock Library

These should be enough resources to get you started.

Regards,

James
