Other Parts Discussed in Thread: MSP430G2403

HI there,

I have a customer who is looking at using the MSP430G2403 for the purpose of cap-touch function.

But he have some questions that i need some help:

1) First time programming into the MCU have to be done by JTAG? can it be done via other means? I2C

2) Subsequence frimware upgrade can be done by I2C at the same time, the state of the IOs need to be held same till the upgrade is done?

Thank you!

    The only way to program a blank MSP430G2xx is to use JTAG (either 4-wire or SBW). There is no other way. Not I2c, not UART.

    2) Subsequence frimware upgrade can be done by I2C at the same time, the state of the IOs need to be held same till the upgrade is done?

    If the MSP430G2xx has already been programmed with a working loader which is capable of loading other programs without hurting itself, than the answer to the first part of the question is yes. I do not understand the second part of your question.
