Re: CAN passthrough with Raspberry Pi

Yes there are a few options possible for providing input circuits for the TIOx such as VR conditioners. But not everyone needs or wants the same set of I/Os so it would have to have some flexibility especially since the VR conditioners are relatively expensive.

Re: Getting Started TinyIOx?

What exactly is your setup in terms of hardware and connections? You TIOx settings are mainly ok but you have changed a few things from the defaults that could create issues such as using 12-bit ADCs instead of the default 10-bit (and what the MS3 might be expecting). Also, you have enabled the ADC ...

Re: I/O Extender availability

Mr. Belanger, Long time lurker, first time poster. I would love to use your I/O extender to include EGT, GPS and a RTC to my MS3. Any chance you might have the pieces available to build a module, or have one available for purchase? Thank you for your time. Hi and welcome to the forum. I'm sorry for...

Re: CAN passthrough with Raspberry Pi

I'm sorry it took me a while to get back to you. I have done a few tests and it seems there is an issue with using the TIOx as a CAN passthrough device with the MS3. I had done tests with the MS2 and, as I mentioned in a previous post, it was fine as long as you only used it for datalogging. That do...

Re: CAN passthrough with Raspberry Pi

That's not a .tsproj file. That's a directory. I need the tsproj file as described. And again, make sure to NOT include the datalogs and restore points; those take a lot of space.

Re: CAN passthrough with Raspberry Pi

Please post your project backup. You can create this from the File menu, Vehicle Projects/Create Project Backup; make sure to not include the datalogs and restore points (uncheck boxes when creating the backup). This will create a .tsproj file which you can post here.

Re: CAN passthrough with Raspberry Pi

I can't help you with the serial port on the Pi because I have not looked into this, I don't have a unit available and I don't have the many hours I'd need to spend on it to get up to speed. So you'll have to get help from experts on the subject on a Raspberry Pi forum or somewhere else. You at leas...

Re: CAN passthrough with Raspberry Pi

Why would you use the can-egt ini with the TIOx? Those are 2 completely different units with different (if somewhat related) firmware. Use only the correct firmware and ini for the device you have.

Re: CAN passthrough with Raspberry Pi

If that was the default setting then you don't have the latest firmware. It obviously won't work if the serial port is set for reading an LC1 but the latest firmware defaults to having the serial port for tuning. Once you have changed that setting, check which version you have (use the Port scanner ...

Have you considered using a USB-serial adapter instead of using the serial port pins?

Re: TinyIOx release 0.2.1 (was 0.2.0)

One thing to remember is that when you use TunerStudio (which is what I assume you want to use for the dash display) in CAN passthrough, you will have to set things up manually because TunerStudio will only see the TIOx which is directly connected to the serial port. So you will not be able to rely ...

Re: TinyIOx release 0.2.1 (was 0.2.0)

That should work. Which pins on the DB9 are connected to the stereo plug? The tip on the stereo plug should be connected to pin 2 on the DB9, the ring should be connected to pin 3 and the sleeve should be connected to pin 5 (ground). If it doesn't work, you can try reversing pins 2 and 3 (that shoul...

Re: TinyIOx release 0.2.1 (was 0.2.0)

You will need something between the pins 8 and 10 and the TIOx. The TIOx serial port jack has RS232 signals so you will need to convert the Pi signal to RS232. And if you wanted to bypass the RS232 chip on the TIOx, you would still need to have a circuit to convert the 3.3V signals on the Pi to 5V o...

Re: TinyIOx release 0.2.1 (was 0.2.0)

The current code will do this only partially. You can read data from the MS through the serial port on the TIOx over the CAN port but you won't be able to change the settings on the MS. So that would work fine for datalogging but not for tuning. I want to correct that for the next release but I don'...

Re: TinyIOX - Speedo Input From LM2907-8

And I should add that you can replace the equation with the simpler version: 12333.3333 / gpiopwmin0 This just does the pre-computation of all the fixed values into a single value. And then you can adjust this 1233.3333 value to get your expected speed. This will have the same effect as what I menti...

Roger, How accurate are the 118.4 mph and 1800Hz you quoted before? And how accurate is your theoretical speed on the lathe? If any of those are not accurate, that will lead to an apparent error. The timer should be much more accurate than this assuming the computation use the correct values and you...

Re: TinyIOX - Speedo Input From LM2907-8

Actually, it was misleading when I mentioned using all the default values. That was only on the TIOx side. On the MS2 parameters you show, you need to change the CAN ID from 5 to 4 and the offset from 58 to 28. And you can use pretty much any diode but small schottky diodes will do such as SR104. Jean
