Re: Megajolt LCD display

Can't believe that a year has passed since I built this: Display.png Just built an arduino based crank simulator which seems to work quite well... only does 5 fixed points for RPM, but that's enough to bench test the display for now. Working on an LED display now with an off the shelf display board ...

Re: Crank Sensor Voltage and EDIS

All sorted. It seems that the old EDIS isn't too fussy about the signal and as long as it goes negative, it'll trigger just fine off a 5V square wave... I just simply added a voltage divider to put the vrs -ve line at 2.5V and all works just fine off the little arduino... much safer than mounting my...

Crank Sensor Voltage and EDIS

I'm looking to make myself a benchtop simulator using an Arduino to simulate the crank sensor. The code to get a 36-1 tooth pattern is really easy and it basically gives a 5V square wave output. My question is, what is the maximum Voltage that the EDIS can handle from the VR sensor? I was thinking o...

Re: Megajolt LCD display

Thanks Brent, i'm more than happy to share this project and source code on here.

Not used the Capri on the road this year, but running it to warm on the driveway is showing that the display is working very well.

This was my first Arduino project so I'm very plesed with it... looking at RFID immobilisers and GPS stuff at the moment, but as for the Megajolt display, I don't think I'll be developing it any further as it does exactly what I intended it to do. If you want the Arduino code, just ask here and I'll...

Just found this thread and realised just how old it is. I have completed a project based on the nixi tube Arduino project and have it up and running off my V3 jolt... The 9 pin serial port had previously been modified to have the TTL level lines output on pins 7 and 8 and 5V on pin 1 for a bluetooth...

With the assistance of a serial port sniffer, I think I've cracked it.

The tuning software seems to send 's' (0x73) and receives 9 bytes

By Adjusting the pot on my test board I've noted that byte 7 changes with the temperature.

Arduino re-programmed and:

I've got this far using the $ command (0x24) Is there a different command that brings in the aux data? I've tried S (0x53) but that doesn't seem to contain it either. "Fan" is based on UserOut1 status as that is controlled from the aux temperature... its blank when its not running Everythi...

Can anybody please advise me of where in the serial string the aux. data is transmitted. Is the support for the V3 finished now? I'm reading the V3 just fine... got Advance, RPM, Load (KPa) and user out 1 displaying useful data... I just need the aux output for the coolant temperature next, but cann...

I think, all I need to know is which byte and which bits contain the aux. scaled info on the serial output on the latest V3 as I have managed to get Advance to display correctly, not tested RPM yet, but that should be fine, Load is now working (different from the V4 sketch that I am modifying), but ...

Serial API for V3.3.1 firmware

Brent Is there a Serial API available for the V3. as the latest seems to be 3.1 and doesn't have the "aux" listed. The reason I ask is that I am looking at the code for an Arduino project to read the serial data. All I can find are sketches to do the V4 and I know the V3 is very different....

I've wired an electrical cooling fan with my V3. And it works like a charm. But...... it is wired so that the fan is fed directly from the battery, then to the relay controlled by one of the user outputs in MJLJ, and then to the fan. The battery in return is connected/disconnected to the the whole ...
