Simple Serial Interface for Propeller Programming

cgracey

Guys,

Sorry if this is redundant in some ways, but I thought I'd post a dirt-simple interface that you can build to program your Propeller chip over a standard serial port.

I haven't tested this, but I'm quite confident it would work.

If anyone builds this, could they please post the results here?

Thanks and Happy Programming!

IT MIGHT BE NECESSARY TO CHANGE THE 10nF to .1uF!!!

Chip,

I have the exact same setup on my board, connected to my old school laptop serial port, and my program compiles flawlessly. Thanks for the help. I would also assume the other design would work as well, as my problem was the computer. A direct serial port, or Parallax usbser thingy would be the best bet.

PS- I used .1uF

PPS- See THIS post for the other idea.

Hi Chip,

Would you mind if I added this schematic to my website?

Thank you

This is already in the prop-manual, data sheets and on the website (various methods) ... so.....????

... but would be interesting to learn whether a 10n or 100n cap would be better
As the internal pull-up is around 10k this will result in reset-pulses of 100µs to 1ms. There seems to be no minimal value for this in the datasheet.
