hi Sam,
Ref your PM, layout on *.gif.

Regarding the PICAXE I dont use that device, perhaps another member will
reply to you query.

In regards to the PICAXE I was looking at this http://www.sparkfun.com/commerce/pro...ducts_id=8321# and thought i might give it a shot. The problem is, I dont have a serial port, so im stuck paying 25.00 for the cable. I have a spare USB cable, how easily could I wire that up to it? Is there a resource for the USB pinout so I could wire it to a plug myself? Thanks

the usb programming cable is not just a simple cable - inside it somewhere is a USB to RS232 transceiver chip - thats why it costs extra.

i can't believe you don't have a serial port - I buy a lot of computers in my line of work and even ones fresh off the factory floor today, notebooks and desktops, have one DB9 port. But anyway, you can grab a usb to serial adapter for under $10 off a popular online auction site

Well, maybe i lied...I do have a serial port for an external monitor, but i was thinking it had to be a printer port. The moniter serial port should work okay?

hi sam,
>>

The external Monitor port is a 15pin Hi-density 'D' connector.

The Serial RS232 port is a 9pin 'D' connector,. [it used to be a 25pin 'D' on older PC's]

The Printer port is a 25pin 'D' connector.

Have a look at 'things' post as an alternative flasher.
