Hi,

General question for you,

If I use MSP430 MCU and use GPIO as clock of 20hz or trigger of 20hz, what is the accuracy on that?

thanks for kind answer.

Hi Wonock,

If you want to use a timer to get needed frequency, the accuracy will depends on what clock source you selected, for example, external crystal or REFO. please check the datasheet for detail clock accuracy.
