Other Parts Discussed in Thread: MSP430G2553

As per the mail received from your side I am now mentioning the whole information here with 'U'

Q.1.

1)U1-M430F1612 

2)U3-IIA7EDW

3)U5-4LC184275H

4)U2-TI0CAGF

I didn't get you regarding U1? You mentioned that U1 means "programmer" that means our code is loaded into U1 and then it is converted into hex file and given to the target through spi-bi wire interface?Is that you mean?

Q.2.Who is converting our  C-code into hex file and giving to the target?

Q.3.Who is converting 5V from PC to operating voltage of msp430g2553 i.e 1.6-3.3V?

    CCS / IAR Compiler / Linker generate object code (or hex or txt) from C code source file. During flashing hex / txt file is divided on PC in smaller blocks and sent to FET. Than FET send this data packed in SBW / JTAG interface to target device. TI FET firmware is open source (MSP-DEBUG-STACK), so you can find there more details, or in slau320.

    Your questions are related to old G2 LP, that is slow, doesn't have updatable firmware and it is with limited support. If you are looking for building something by yourself than eZ-FET lite is much better option.
