Slave Mode w/ PC?

ALIBE

Is Propeller able to function in slave mode w/ a PC or PDA (such as iPAQ)?

Any ideas or pointers to existing threads.

Thanks

Can you be a little more specific? If you are asking if the propeller can sit on the other end of a serial connection to a PC, take serial commands and act upon them, then yes it can.

Sure, why not? Just setup a serial connection with the PC and do whatever you want to do.

Generally, I suspect Slave mode is easier than Master.· I presume you mean Async serial in this case as a PC is involved, but I think you can generalize to all serial slaves [noparse][[/noparse]including SPI and I2C]

The Slave takes·direction from the Master and merely has to wait for the Master to iniate communications and follow a standard routine according to whatever the request is.

On the other hand, the Master has send, recieve, and often verify what the Slave is doing.· If it is not correct, the errors have to be handled with a repeat attempt or other remedies.· There may be more error trapping overhead as the validity of the data may be·in question·[noparse][[/noparse]CRC, parity, etc.].·

Kramer, I'm thinking I would implement a custom RS232 handshake w/ ref to CRC/Parity/etc note you make

Paul, Jon; thanks for your comments. I might dedicate a cog to handle the comm channel btwn PC and Prop. and see how that shakes.
