Are you fully powering down and repowering properly to test these "bad burns" ?

Sometimes, depending on how lazy I'm feeling.

I don't what its problem is tonight, but just about every BDM power supply load looks something like this. I'd say the verify is working. If my scope wasn't out in my car I'd hook it up to my computer to look at how stable the power is.

One very tiny bug it seems to have is it doesn't reset the error counter if you have a successful load after one with an error in it.

[Fred]

Good work! I wonder if after a verify fail he is resending that data, or just carrying on and reporting it. I hope he's resending because the message says "all done, use me" Thanks for the testing :-) Now get back to your study :-p :-)

[Fred]

Dave just improved the message so that it tells you to redo the burn if it had issues.

Cool

A little bit of documenting. Even though it's almost exactly like the datasheet.

[dandruczyk]

Current mtx (hash f9c1e4d1e7abb254fe3cd93dca08168fcb9fee41) has a retry after verify as well as better log messages to indicate failures.

Give it a try.

I will, thanks.

I think I might have found the problem with the 5V power supply from my desktop.

1.2V peak to peak wave form. So I stuck a 1000uF capacitor on it, and now I have a nice strait line. I'm kinda surprised the the computer is still running.

Nylon carpet in 0% humidity is a static free work station, right?

[Dan]

LOL ! I love the static free environment!

Peter, I don't believe that you can use the D44VH10 as your injector driver as it doesn't appear to be a darlington transistor. The datasheet (from ON) specifies it as a "normal" NPN power transistor. It doesn't have sufficient current gain to be driven by the LM1949 into saturation (with a low Z injector load).

Thanks,
Huff

[Fred]

Nice spotting Huff!!! He's right Peter! Something more for you to fix before we get serious with this thing :-)

[Peter]

Is the EGO suppose to look like this?
