Hi team,
Here's an issue from the customer may need your help:
The msp430 is powered by two dry batteries at 3.0 V and has a 220-UF capacitor that continuously powers the MCU after the battery is removed and powered down. Since the MCU is in sleep state and the current is only 1UA, the capacitor discharges the MCU for longer than 1 minute.
The customer now would like to monitor the MCU supply voltage with the MCU internal voltage, read the internal supply voltage every 5S. Can the MSP430FR2111 do this when the MCU turns on the LED to discharge quickly when the second read exceeds 0.2 V from the previous read?
For the above operation, is there any demo program for reference?
Could you help check this case? Thanks.
Best Regards,
Cherry
