Re: XGATE PIT based bit bang fuel injection
This code *almost* worked and worked for a short time perfectly until something went wrong. Ain't this always the truth mate!?! Looking at this code could do one of two things: A) poison your pure mind B) help you see some ways of doing the job It's up to you if you look at it or not :-) Fred. I'm ...

Re: Puma board for FreeEMS
Oh, I'll get to it eventually. I had a bit of a hiatus and need to get back into the swings of things. I like the look of the connector combo - ALOT. It gives flexibility but also if somebody was dead set on a panel mount port, it looks like it would be very easy to use the through-holes for header ...

Re: Puma board for FreeEMS
I just created a footprint for the combo u-mini-header, and pushed to github. About all this stress relief on a data connector, shouldn't we jump the wireless gap? I'd still like to see a chip we can put on puma, that emulates 232 to the MCU, and a software driver on a PC that emulates a 232 connec...

Re: Puma board for FreeEMS
I vote, we include the mini/micro and header pins. I don't like the header pin(s) idea, as they are another place for a signal to go wrong, but I can see the desire if you have space constraints that prevent you from putting a strain relief on the USB cord. I'm seeing if I can smash together min/mi...

Re: Puma board for FreeEMS
Otherwise it's a wash because the pads are gonna be the weakest link. I was thinking this too, as I pulled a few pads off my puma before I got good at modifying it :-) You're dead right. That said, perhaps a USB pin header and a panel mount USB port would be a nice build-time option. Though in any ...

Re: Puma board for FreeEMS
Micro USB specification requires minimum of 10 000 mating cycles for the connectors, which is considerably more than Mini (which is around 1000 I believe). What I am most concerned about is lateral force. Let's think about how this is going to be used. We are going to bolt the ECU to the car and ha...

Re: Puma board for FreeEMS
My observation is that Mini is on its way out, especially in the Cell Phone market. That said, I have about 100 Mini cables, so I ended up buying a small lot of Mini-to-Micro adapter whips from Motorola. They were ~$1USD each and now I never have to worry about whether my device is mini or micro. I'...

Re: Puma board for FreeEMS
Is that Mini or Micro? Not really any difference footprint wise, but Mini sure is more common. Of course, most cell phones are going to Micro so that may not be the case anymore...

Re: Puma board (spin 1)
I watched all the Vids. I'm impressed. Wish I could have been around more to see it progress. I'd potentially take an Option 2 board if one became available. Wouldn't mind farting around with one if nobody else wants it. Just don't want to take one from somebody who'd provide a lot of immediate feed...

Re: Puma board (spin 1)
AWESOME!!!! I want one, but I think I'll wait for Spin 2. Not sure I have much time for debugging
BTW: Thanks for the email Fred, even if it took me two months to find it. Gonna have to update my email address on the forum.
