Thanks. I will get on to that. Any tracks I need to cut at this stage?

Oh yes, take a look at the images here:

we're working on another doc, but is not yet ready.

USB stuff needs more mods that are being documented now, for example

What he said.

Once you have the SM loaded you need the load/run sw or jumper and the capacitor to test the SM. So you may as well put them on so we can test it after loading...

Just drove hotel hyundai on full ignition timing control (not straight wire dodgy code), about to post in my thread :-)

Will I need the USB chip and mods to do this testing?

yeah, or an rs232 converter chip and usb2rs232 converter (can use one of mine if you dont have one) but yes, you would.

Nah, populate the FT232, 2 caps, 2 resistors and you're ready to go. You may want to cut some traces for the usb chip (Fred modified his board, I didn't had problems so far)

Don't "nah" me... how rude!

The suggestion was to get it running now, as opposed to later after you get your docs done so he can order the rest (along with everyone else). If he happens to have that stuff laying around, it will work admirably.

As for the usb mods, they are not going into that doc as optional, in real world usage, its totally inappropriate as is, so they should all be modified, it'll just be part of the "do this next" instructions, somehow.

+1. I should be able to get this going with an RS232 converter I have. I don't want to wait for a USB part to come in. I should be able to find all the other parts I need.

Ooh, you only have the cpu.

Can you get a 16MHz SMD crystal and the 0805 stuff?

Yes. No Problem
