Jeff,

All the settings look fine from your pictures but I still would like to have a look at both your msqs if you can post them.

I connected my LC-1 to my old desktop with a real serial port to conform that the LC-1 serial port was alive. That step reminded me that I stole power for the LC-1 from the fuel pump supply. Now I'm wondering if TinyIOx is getting confused by the LC-1 coming online for 2 seconds during the fuel pump priming pulse, then going offline when the pulse ends, and then coming back online when I start the engine.

I will connect the LC-1 to a conventional hot in start / hot in run power source, but more TinyIOx troubleshooting will have to wait as my fuel pump decided to fail yesterday.

What do you think about LC-1 -> TinyIOx comm being interrupted?

That shouldn't have an impact because the LC-1 will continue to send data and the TinyIOx will resync with the data due to the Innovate protocol.

OK, thanks for the reply! Using MS3 output test mode to hold my fuel pump voltage on, I can read my LC-1 serial output with Logworks, so I know the LC-1 and serial cable are functional. My car will be on stands while the second failed fuel pump is repaired (less than 5 minutes of run time!) I'd like to send my TinyIOx back to its maker for a checkup. It appears that all the other links in the chain are working. Is that OK?

Jeff,

Before we do that, can you check something for me? Can you check that the Innovate cable is a straight through cable, i.e., the tip on one side is connected to the tip on the other side, the ring is connected to the other ring and the sleeve is connected to the other sleeve. In the tests I've done, I used a straight through cable (normal stereo cable) because I did not have the Innovate cable.

Also, can you post a picture of your board because I'd like to check something.

I ohmed out my serial extension cable (male to male), it is straight through: tip to tip, ring to ring, sleeve to sleeve.

I've also reconfirmed that reasonable digital data is coming from the LC-1 by hooking it up to Logworks with the sensor in free air. It reads 21.8% after a free air cal.

I reconfirmed that my MS3 is talking to the TinyIOx. The real time TinyIOx gauge in TunerStudio displays a constant 8.00, which what I told it to display in case of trouble.

I've attached a pic of my TinyIOx. Is the DIP switch supposed to be set to on? Edit: I see that it controls the 120 Ohm termination resistor. Since I have a 2-node bus I'm assuming it should be set to on.

Yes the switch is supposed to be set to on unless you have other devices connected to the CAN bus. It is used to connect and disconnect the terminating resistor. And since you can communicate with the TinyIOx, it is working fine.

Everything seems to be configured correctly and the hardware looks to be as it should. There is one thing that could still be a problem is if the LC-1 is in one of the modes that isn't supported by the TinyIOx but since you say that you can read the AFR from the PC that means the LC-1 should be sending AFR data which is what the TinyIOx can read.

So that looks like you may want to send it back so that I can have a look. I'll PM you my address.

Hi, Jean.
Quick one - which ADP pins on the IOx-OEM match up to the TinyIOx ADC0 and ADC1?

cheers,

Don

Don,

The IOx-OEM uses the same mapping as the IOx (and the same code) so ADC channels 0 and 1 correspond to ADP10 and ADP19, respectively.

Im having issues trying to update to the latest TinyIOx firmware.

I run "tinyioxdl.exe com11 115200 tinyIOx.s19", and get:
Code: Select all
Parsed S-record lines: 360 Bytes total: 11455
Source address range: 0x1900-0xFFFF
Error in getting signature


The TinyIOx currently has the default FW (whatever version it was supplied with), and does work ok (ADC vals all look ok in TS).
PC is Win7x64.

Are you connected to an MS2 or an MS3? If you are connected to an MS3 with the latest firmware then the TinyIOx downloader needs to be upgraded to support the new serial protocol.

There is now a downloader available that will work with the new MS3 serial protocol: http://jbperf.com/io_extender/firmware/ ... dl_ms3.exe. You use it the same way as the other original downloader.

There will be a more unified downloader at a later time that will deal with any protocol version.

BTW... can we have a TinyIOx subforum?

If you are not going to write a manual or similar, it would at least make information a little easier to find.

If one wanted to add simply conditioning circuits for 0-5v, what is the minimum recommended circuit?

The minimum circuit I would use for an analog circuit is 2 capacitors and one resistor. The generic values I use are: a 1nF cap between the input signal and ground followed by a 1k series resistor and 0.22uF cap between the ADC input and ground. So you have a series resistor with a cap to ground on each side. You can have a look at the different MS schematics to have different variations.

Jean,

Im trying to get an accelerometer that ive attached to AD7,8,9 working.
It works fine viewing the realtime-display->all-output-channels dialog.
Im having trouble getting it working with MS3's accelerometer input though.
Which "CAN ADCxx" inputs do i use?
Or do these only work if ADC CAN polling is enabled? If so, how do i go about setting it up?

Thanks in advance.
