Powering the MSP430F5438A

Other Parts Discussed in Thread: MSP430F5438A

Recently, my msp430f5438a, on being plugged in to my PC, gave an error saying that the supply voltage was too low (1.4 V). 

Can the power provided by the JTAG interface be complemented with an external source. Is that the way to solve the aforementioned issue?

Thanks

    Hi Rahul!

    Are you talking about a LaunchPad or a custom board?

    You cannot literally "plug a msp430f5438a in a PC" and the msp430f5438a is not capable of literally "gave an error saying ..," ;)

    You probably mounted your msp430f5438a on some kind of circuit board, connected that circuit board to some kind of hardware FET tool, and plug that FET tool to a PC. And you probably ran some kind of program on the PC that gave you such error message.

    If so, please describe briefly (a) what is that circuit board, (b) what hardware FET tool is used, (c) how were the connected to each other, and (d) what PC program you ran.

    These are what i had used:

    a) The circuit board is custom made

    b) An MSP FET Debugger

    c) Connected via JTAG connector

    d) The software used was IAR for MSP

    If your circuit board a) has its on Vcc supply, you should use that and connect that Vcc to pin 4 of the JTAG connector c) -- do not connect anything to pin 2.

    If your circuit board a) has no Vcc supplier of its own, you could connect its Vcc to pin 2 of the JTAG connector c) -- do not connect anything to pin 4.

    Check slau278.pdf (the latest version is slau278y.pdf)for all other connections.
