5 Cylinder

posted Oct 12, 2015 22:44:35 by PaulJessop
I've been looking for shift lights for my Volvo and stumbled across this, I love it, Much better than others I've seen and much more interesting than buying one. Will this work OK with a 5 cyl?

Thanks :)

Yes - it should have no problem. There is a setting in the menu called "PPr" that is used to tune for any cylinder configuration from 1 to 32

I thought as much, Still waiting for all my parts to arrives. I'm really looking forward to building this and trying it out.

Cool! Please post up some pics when you get it finished and installed! If you have any questions, drop me a line in here.

I certainly will, I got picture mad with projects.
There is one question I have, I am always trying to make the projects I do smaller. I've not checked this out yet but, can I use a mini pro instead of the uno?

Yes it should work - although you just have to make sure the pins are the same from the UNO to the MINI PRO -- pretty sure they should be OK because they are both based on the ATMega328 processor. My concern would be the interrupt pin (#2) - otherwise it ought to work fine.

Just looked at the schematics of both, can't see it being a problem. I'll try it out anyway.

Just about done, just waiting for the rotary encoder. Will the led display and the pixel strips do anything without the encoder connected? I'm going to presume not as mine isn't. I've used example sketches for the display and strips, both are working fine

It should display something even without the rotary encoder, although chances are it won't be correct until you set the correct PPr in the menu. If not, you might need to run the EEPROMreset code - that usually resolves any issues with it not-starting, it needs a clean EEPROM off the bat to get going.

I cleared the eeprom and it lives. Just need the encoder to hurry up now

Awesome!! It's ALIVE!!

Encoder has arrived, All working now after a bit of confusion. On the schematic, it shows the centre pin to gnd, this didn't work for me, I had to connect the centre pin to +5v. Next step is to try it in the car at some point.

Here is a short vid

I'm using 2 nano's. One for the RPM generator and the other for the lights

Awesome work! Thanks for sharing. I'm a little surprised the encoder didn't work w/ center connected to ground, but sounds like you got it sorted. Be sure to post pics of the final install too!
