Isn't the whole idea of a wiki that the users can update the pages to fix the typo's and such. BTW, the page with the bad info is:

I have used a sensor like this one, to produce a 0-5V signal that can be calibrated:

Connect this to an analog input and log or display the current consumption.

Or use a 16 bit value for speed, instead of a single byte.

It seems like all the ASL devices have a the CAN bus terminated, and you cut a trace (or disable in software) the termination resistor. I was just responding that you should have termination at your two "end" devices, and none on any of the device in between. The lengths of your "branches" on the CA...

AX1 & AX 2 should have CAN termination, all of the other CAN devices should not have termination.

It looks to me like because you are using stepped style, you set the number of LEDs in the sxSetLinearThresh to 0 for each threshold, you probably only get one (or two because centered) light per threshold. I would first change the number of LEDs per threshold to something non-zero. You can define u...

It's not clear to me that the FlashPro sends the same data as the KPro produces from Hondata boards. The KPro and S300 are add-in boards, with their own CAN bus output (at least in the case of the S300). But before giving up on this, I would load the KPro Preset into RCP Setup/CAN Mapping, change th...

Did you follow these steps listed as the "Alternate Method" While holding down the button on RaceCapture/Pro, power it up by plugging in to USB. You should observe a rapidly flashing LED on the unit: this means it's in bootloader mode. Start the app. Note, it will not be able to connect - this is ex...

Is your HonData configured to send CAN data? You should verify that the correct CAN bus speed (baud rate) is set. I suspect the HonData is 500k baud, but am not certain. Perhaps you can find someone knowledgeable with the CAN bus to help you. I would connect one of my CAN inspection tools (or write ...

Well, there is a little "2" in the lower right corner of that box that represents the bit number. I would say (and I did say) it would be 2.

But you have the case to test.

Which one works?

Based on what some other brands are able to do, it looks like there could be some useful data available. It's a bit of a job to reverse engineer the CAN bus but it is possible. Looking around, I think the CAN bus might be 250kbit/sec, and the Honda Civic might be using the following CAN IDs: 1684 (0...

When it Bit mode, the offsets are in bits (0-63), and the lengths are in bits as well.

I would try the following:

Case A: Offset 2, Length 1
Case B: Offset 16, Length 12

I think you want to use getChannel() as defined here in the API:
