MSP430FR5889: MSP430FR5889

Part Number: MSP430FR5889


fOR THE PAST TWO MONTHS i HAVE BEEN ASKING FOR SUPPORT REGARDING PORT 1,WHERE if we use only PORT1.2 AS ANALOG INPUT IT IS ALRIGHT .But in the same port1 if we use others as digital outpot, the ADC READING CHANGES.

My project is held up.Can this be physically checked in a demo board and informed.I had many a times sent the initialiasation code also and if needed can be sent again.

Request that I am helped

  • Hi 

    The ADC input A2 channel will not be influenced by other port1 device as GPIO. Have you measure the input voltage by a multimeter of P1.2 when output other Port1 pins? Can you confirm that the input voltage is constant.
