msp432 timers

Other Parts Discussed in Thread: TMDSDOCK28035

I WAS INTIALLY RECOMMENDED TMDSDOCK28035,  I WAS TOLD BY A DEVELOPPER THAT MAY BE AN OVERKILL AND SHOULD LOOK AT

THE MSP432.  MY TASK IS TO READ TIME INTERVAL FROM 2 EA EXTERNAL SIGNALS TTL AND MEASURE THE TIME INTERVAL FROM 200 NANO SECONDS TO 1 MILLISECOND IN CONSECUTIVE ADDRESSES UP TO 1000.  THEN IS WILL EXPORT SERIALLY TO ANOTHER COMPUTER.

WHICH ONE OF THE 2EA. PARTS WOULD BE BETTER AND SIMPLE.

  • Hi Mark,

    The MSP432P401R has four 16-bit timers with a max input clock frequency of 24 MHz and a minimum pulse capture duration of 20 ns (Section 5.25.10 of the Datasheet), therefore it is capable of handling your application. Four eUSCI_A and eUSCI_B modules are also provided for your serial communication needs. TI provides several code examples to help jump-start development: www.ti.com/.../slac698
