Part Number: MSP432P401R
Hi,
I'm trying to set a timer that toggles at a frequency of up to 10Mhz using an interrupt to send multiple signals to a different device. I'm using the sample code cs_hfxt_start.c in the MSP432WARE driver library but the SysTick_Handler(void) interrupt function maxes out at approximately 400kHz, which is at MAP_SysTick_setPeriod(60); and going lower than 60 does not increase the interrupt speed. Is there an alternative to this current solution? Could I change the hfxt crystal to a faster one or is there a different method to trigger the interrupt at a faster rate?
As well, I am also trying to receive a clock signal of unknown frequency of up to 10MHz from a different device. Would I be able to do that with the gpio input interrupt at 10MHz?
Thanks,
Maria
