Precise timer on 243x-EVM

Hi,

I'm using the 243x-EVM with mcu_plus_sdk_243x_08_06_00_43.

I've used the syscfg to create periodic timer for every 32 usec.

How can I create a timer for 31.25usec ?

Is there an example project for precise timer ?

Thanks,

Eli

Hi Eli,

As you can see in the following example.syscfg, you can actually set the fractional of the us, but due to the accuracy of the timer clock (25Mhz) and integer divider requirement, the actual tick period is set to 31.24us (instead of 31.25us).

Best regards,

Ming
