so I ordered one of them 3.3 tranceiver breakout board thingies but for the life of me I don't get why I can't initialize the ISA current sensor using Damien's v2 VCU I mean it ought to have the tranceiver built in right for it to read CAN data once initialized?

moving down the list the second set of CAN Bus wires was next, this is additional CAN in addition to the CAN on the B Connector my 1971 Chevy truck predates CAN Bus architecture by a couple millennia so there is nothing to integrate with meaning we don't need these two Pins VCU Wiring A Connector - ...

Thank you I appreciate that.

I realize all this is documented on the Wiki but I just like to have it all in one place for the next poor soul who comes along and encounters the same problems as I have, so this is the code to initialize the ISA shunt for the Arduino Uno (which appears to work with the Due as well) values in red h...

Progress Update... finally made some headway! So I decided to try the Arduino Uno code off the Wiki on the Due I mean why not, it's a totally different microcontroller that uses totally different libraries, no reason for it not to work right?! well with the SPI_CS_PIN changed from 10 to 9 and the da...

so I finally stumbled upon this Wiki page by dumb luck just Googling CAN bus with Arduino Due to which there is no link off of the Isabellenhütte Heusler Wiki page at all which reads: "The Due has two on-board CAN interfaces. However, the board lacks the necessary CAN transceivers to make then ...

guys I am a total newb so I have to ask what in the world does this mean, it seams to me like the module is stubbed out Sensor.debug=!Sensor.debug; or this Sensor.debug2=!Sensor.debug2; per the attached User Manual they should look like this no? Sensor.debug=1; Sensor.debug2=1;

seeking a cheaper alternative I stumbled upon this article Arduino Due CAN Bus (Controller Area Network) Interfaces which provided three alternatives and a tiny dinky dink called a Breakout Board $10 bones on Amazon it read: "In order to add CAN bus transceivers to your Arduino Due, you will ne...

Found this thread on the Arduino Forum: Arduino DUE and CAN BUS SHIELD seems like the exact same question I am asking, well that thread led me to sum sticker shock! complements of EVTV.me they make this CAN Bus Shield specifically designed to fit the Arduino Due for $149 bucks CANDue2.2small_medium....

then I tried the CAN Bus Shield atop of the Arduino Due (though I am not sure that is even supported, word on the street is they make special CAN Busers for the Due, correct me if I'm wrong) well at least this way I could see some LEDs light up when I connected the CAN high and low wires to it, unli...

The pin numbers in firmware don't relate to the pin numbers on the connectors. They map the signals in firmware to the correct port pin on the microcontroller (there are way more than 50 pins on the MCU). Also it looks to me like pin #17 on that connector is "IN1" when I read the schemati...

here is the ISA Scale Test dm2 Sketch for the Arduino Due that I got off the Wiki link and am running in order to Initialize the CAN Bus I can't get this to work #include <due_can.h> #include "variant.h" #include <ISA.h> #define Serial SerialUSB //Use native port template<class T> inline P...

Then I tried it using the VCU itself by connecting the CAN Hi and Low signals to pins 19 and 18 respectfully and following the Wiki for the Due instructions I tried it by saying the CAN port is on 0 or 1, I tried it by saying use 500 or 1000 kbps data rate and no dice does not work!

I believe my ISA sensor is good because I got it working with my Arduino UNO (Elegoo technically) and a CAN Bus Shield

So I went out and bought an Isabellenhütte IVT-S 1000A current shunt on eBay and they sent me the wrong one. I thought I was buying the exact same one as shown on our Wiki , you know the one with the three Volt sensors on top and two CAN ports on the bottom, well they sent me the model without any V...

alright moving down the list, next is Pin #17 on the gray A Connector, in the code aka Sketch it is defined like so on pin 50 (can someone explain to me how it can be on pin 50 out of 40 total pins between the two 20 pin connectors? ha ha) #define Out1 50 this one controls the HV battery Main Contac...

So my not doing continued and I was not doing anything just fine until I came across the Oil Pump wiring/pin out, I know I can ditch the Oil Pump relay on pin 15 on the gray A Connector, but as one forum member suggested, can I repurpose Pin #6 on the black B Connector for the Oil Pump PWM ? Though...

and let's not forget how simply changing our tire aka wheel size can impact RPMing and MPHing below I use the exact same tire profile on three different size rims 16", 17", and 18" Wheel Size.jpg Don't forget to account for the gear reduction from MG2 speed. is it 1.900 ? talk-to-me-...

this made me consider Taller / higher differential gears like the 2.73 for my GM 12 bolt to drop the RPMs by approximately 2 grand, I'm pretty sure (97.1%) that electric motors don't have a traditional Power Band, so did the "Royal We" determine at what RPMs this Unicorn is most happy happ...

Since my 1971 Chevy truck aka GMC used a mechanical speedometer which I am ditching I plan on using MG2_Speed to calculate my miles per hour MPH so I punched some numbers into the good ol' Lotus 1-2-3 (pronounced: Excel) ha ha to correlate RPMs to Miles Per Hour based on my 3.73 rear end and 215/65R...

Since I completed my entire wire harness before I realized that none of those work, I've left it all. It's easier than undoing it and maybe someone will eventually work out the temp issues. I am considering removing PB1-3 however to use those as auxillary 5v inputs. Maybe for cruise control. I real...
