This isn't anything new or DIY related (unless you want it to be, of course) Msd and others do these units, they are very available. Google two step ignition

Oh I thought it was cheap... Soz

Wow that is suuuuper nice! For some reason i was expecting any color but that beautiful blue.

I found the problem (I think) The libraries share a timer. Anyway.. have soldered one nano to a plug and put it into a box..

How about changing diff ratios? To get some more rpms. I also am surprised it's as bad as you say... I do worry that you could spend lots of money and get fuck all gains.. why don't ya get it on a Dyno and see if hp is where it should be and ask them if they have had na 2js on there that they could compare it with. Even a decent tunable ECU may way it up better than a swap.

Hi guys,. Okay, two simple (probably related problems that i cant solve via google) I decided to use the tone function to reproduce the oldschool CLICK sound that would happen when indicating. The code is extremely basic and near impossible to fopar HOWEVER it makes my whole program extremely unstable which leads to the screen randomly displaying garbled garbage which DOES NOT rectify itself on reset. The second issue was with a simple piece of code that played a series of around 10 tones with ever increasing pitch. If i leave the arduino looping the code and playing the tone sequence over and over EVENTUALLY it starts either skipping notes or simply playing notes at random times out of sequence. Any idea what could be up here? I'm using a little buzzer piezo thing from a PC without a resistor... could it be drawing too much juice and making shit go bad that way?

that sounds like a waste of time. Swapmeet purchase?

I feel like gregs post didn't do Chrome justice- What an awesome day! There were a few issues but would have felt strange if there wasn't. Dunno if i should share my vids here..Feeling insanely pissed off because a few of them have gone missing/been deleted accidentally

Nailed this issue Was looking through an example and noticed this in the sketch A simple copy paste to change from option 1 to option 2 and its away I copy pasted out a long benchmark (just filling the screen with different colors over and over) with a time running counter displayed at the end and tested the two options. before it took 153 seconds to run the sketch, got that down to 33 seconds

thanks guys. I think at the moment it is SPI. Will double check things. Good idea about argument Ned!

Wait.. is this EFI or not lol So cool tho

Hi @Scrubb. Is that directed at me or someone else? @h4nd I could never get the drop-through code to work nicely and have moved onto trying other new things. I guess its not ever going to be a real issue for this code because its so basic AND there is nothing critical happening that will get upset if there is a small delay. (eg If the battery icon takes half a second to pop up- who cares) I have tried using the software you suggested but i'm a real Barry these days- the basic normal IDE is so much easier for me to navigate round and learn in. I haven't had a day off for a while so progress is slow but this is the code I now have working well enough to prove I can do it. No longer using external resistors, using an OLED rather than TFT and drawing the icons using the line command rather than triangles and squares. Only two icons because they are being redone again once the larger OLED arrives. Compared to the TFT the OLED seems to have an extremely slow communication speed with the arduino. Even the various Youtube tutorials show the same issue but offer no explanation. This is the reason for changing from SOLID objects to simple outlines- must be less data to send. and this is what it does.

Thanks guys. I have moved on to an oled screen.. FAR FAR FAR nicer than the TFT I was using- because the TFT has terrible viewing angle. @ajg193 thanks I'll look into those too

@64vauxhall

Thanks mate, very kind of you to spell it all out for me! ....now if only I wasn't stuck at work today.... Edit. Have read through that quite a few times to try figure out how it works. When you say read through the library- is the library opened in the Arduino editor like any other code? When you say reset the screen during a button state change during on/off....what exactly do you mean? I have fillscreen black in the setup which kinda erases everything

OK @h4nd i could seriously use your help here. I could not figure out how to get the no-delay style of things to work. I had it running poorly (can show code) I realize that new button presses are not picked up until the end of the currently operating piece of code but this delay is not a problem in this situation (im making excuses) So here is my new problem. When i run the last block of code and the button is held down it flashes the B because it is refreshing things over and over and over. So is there an easy way of making it run once per button press? i'm guessing you know how these screens work- they hold the current picture unless you cover over it with something else so if it sends the red box then the letter B and then NOTHING ELSE until the button is released it'd be OK.

OK fark thats confusing. Tempted to get someone else to do it but that would be defeating the purpose.

Perfect thanks! Will try work this out tonight. At the moment it's kinda cool because if you indicate AND use hazards it will alternate between the two.. however I knew this would cause issues with adding other icons. Thanks man!

I was showing my wife... she shook my hand, held back some lols and said congratulations you have rebuilt the wheel what an egg

OK so got my arduino nano yesterday- I have one with header pins soldered to the bottom for breadboard setup and another with no pins that i will maybe use in the vehicle. Yesterday was a write off as it took me AGES to actually get the unit communicating with the PC, and a few hours of head scratching tonight has got me far further than i thought possible. First of all- the TFT requires 3.3v for the screens LED... great because the NANO doesnt have onboard 3.3v output. Instead i have had to use a breadboard PSU which isn't a bad thing as it means i can use it to output 5v and 3.3v from a 9v when its not plugged into the PC I started by getting some adafruit example code to run. Initially its like WTF IS THIS and i found the easiest way to figure it out was to DELETE code piece by piece to see what changed/failed and then work out why... eventually i had it broken down to a triangle drawing command- figured out how they were manipulating it and changed the numbers to give some nice looking arrows. And then headscratched some more to figure out the switch, delay, loop stuff. Extremely basic but momentous when i got to this point. The arrows can become more fancy later.. im still trying to work out how to make it do more than one thing at a time etc etc.

@chris r I will judge you if you buy that

jesus christ. they have a bit more steel in them than i realised. be so much easier to just put it on a better chassis.

haha. Yeah but 1.2 is so much nicer to weld for the same reasons. and it feels so much more sturdy in floors etc.
