Required Help for MSP430

msp430 bcd

Hi!

I am doing some projects using MSP430 and I am in a hurry.

If any body has ready routines for multiply & divide functions ( 32 bit x 32 bit ) & (32 bit / 32 Bit). 32 bit binary to BCD and BCD to 32 bit binary conversion subroutines.

Any link to a source having this and other ready subroutine will be apreciated.

Thanks

Bye

generation of random numbers msp430

May I do a quick check with u guys here? How much is the output current of the UART-TxD line? I think the output voltage is abt 3V, right?

Is it possible for me to use this TxD line as a power source to supply an IC, if it needs only 0.7mA, while transmitting data?

Thanks,
Eric Mar
