MSP432E401Y: rtc on MSP432E401Y?

Justin Davis36

Part Number: MSP432E401Y

Does the MSP432E401Y chip on the MSP432E401Y Launchpad have an RTC?

However, I'm not able to include the RTC header files from driverlib and I see no mention of an RTC on this page: http://www.ti.com/product/MSP432E401Y?jktype=soc

Hi,

Also, did you try/find any rtc related examples in the SDK?

The P4111 link is a different MCU so I'm not sure that would be helpful. I know how to use the RTC with the P401R.

The SDK for the E401Y does NOT have any RTC examples in any of these locations:

C:\ti\simplelink_msp432e4_sdk_3_10_00_11\examples\nortos\MSP_EXP432E401Y\drivers

C:\ti\simplelink_msp432e4_sdk_3_10_00_11\examples\nortos\MSP_EXP432E401Y\driverlib

C:\ti\simplelink_msp432e4_sdk_3_10_00_11\examples\rtos\MSP_EXP432E401Y\drivers

So does that mean this chip does NOT have an RTC?...or at least it doesn't have a driverlib interface to it?

PS For reference, the P401 RTC example is here:

C:\ti\simplelink_msp432p4_sdk_3_10_00_08\examples\nortos\MSP_EXP432P401R\driverlib\rtc_c_calendar_alarm_interrupt

There is no RTC shown on the block diagram. I guess with the whole internet available with the Ethernet connection, you don't need one.

I think the RTC is part of the Hibernate module, though it's my understanding it can be used outside hibernate mode.

I see a driverlib example called "hibernate_vdd3on_rtcwake", but I haven't tried it.
