Hi Jean,
I have purchased a TinyIOx, just to have more analog inputs to show extra temperatures on the dashboard of Tunerstudio.
It is installed with the CAN bus. When I launch "port scanner V1.2" then it finds my megasquirt and the TinyIOx, I can flash in the latest firmware. So I have communication.
Tunerstudio is modified, so I have the device choise between my car project and TinyIOx (CAN4).
In TinyIOx setup, in "Base I/O settings" I have set ADC to enable.
in "ADC channels activation" I have set ADC channel 2 to active
I have put a adjustable 0 to 5 volt signal at AD1 for testing (it comes from the power supply, so GND's are connected)
In Tunerstudio I have created a extra gauche where controller is set to "CAN4" and output channel to AD1.
And now, when I change my signal, nothing happens. The new gauche does not move and when I go to "CAN4, Data, Real time display" all the values stay at 100.
What am I doing wrong?
Best regards
Marc

Re: TinyIOx
Marc,
You will need to post a backup of your project because I need to see all your settings. This is under File/Vehicle Projects menu. Make sure to unclick the boxes on the right in the dialog window so that the datalogs and restore points are not included: this should make the backup file a reasonable size.

Re: TinyIOx
Hi Jean,
I found the problem.
As outputchannel I have to take GPIOADCx instead of ADCx. Now it is working.
Thanks for the effort.
Next week I will order 2 more TinyIOx.

Re: TinyIOx
Hi Jean,
I want to order 2 more TinyIOx boards, but I see that sale is suspended.
Can I still order them?
One more question: is there a terminator resistor for the CAN bus on the board? If yes, which one is that?

Re: TinyIOx
Marc,
The ordering button should be back online sometime this week. I'll post here when it happens.
And yes there is a terminating resistor and that's what the DIP switch is for. The switch enables (switch on) and disables (switch off) the resistor so you can have multiple boards on the bus.

Re: TinyIOx
The TinyIOx ordering is back online: http://www.jbperf.com/io_extender/tinyIOx.html#Buy.
If you were considering buying a TinyIOx in the near (or not so near) future, you may want to do so now while it is available. The current batch is limited and I'm not sure when the next one will be available.

Two orders for TinyIOs heading your way, Jean. Hope you can keep your very useful product line open.

Re: TinyIOx
Hi Jean,
Hope you are doing well!
After an unexpected break, I am working again on this project.
Everything is working, except getting decent values on the gauges.
In tools I have filled in the calibration tables for CAN 4, in "Led displays" "Sensor calibration" I have connected the calibration tables to the sensors.
Probably I am using the wrong gauges. Which gauges output channel should I use to have a "calibrated" gauge? There are so many channels that I do not see the wood for the trees.
Thx
Marc

Re: TinyIOx
Marc,
In the current firmware, the calibration tables are only used to display values on the LED displays; that's why they are located in that specific dialog window. You can't get the calibrated values directly in the gauges in TunerStudio.
You can still get calibrated values in TunerStudio but you will need to either use a custom.ini file or use the channel editor and wizard: http://www.tunerstudio.com/index.php/tu ... nel-wizard.

Re: TinyIOx
Hi Jean,
Back again with another question.
Is it possible to put the newly generated channel (by the custom channel wizard) back on the CAN bus, so I can put it on an external display?
Thx,
Marc

Re: TinyIOx
Marc,
The generated channels only exist inside TunerStudio on the PC. The TinyIOx has no knowledge of it whatsoever so it cannot put it on the CAN bus.

Hi Jean,

I want to order the "PWM convertor board", but there is no "add to cart" button to order it.
How can I order it?

Re: TinyIOx
Marc,
It's no longer available. But with a TinyIOx, you should not need one since you can have pretty much any PWM frequency.

Re: TinyIOx
Jean,
I do not understand how to do that.
I want to convert the existing pwm output signal for boostcontrol to a higher frequency than provided by megasquirt. I want a pwm signal with frequency of 2 kHz.
How do I do this with a TinyIox?

Re: TinyIOx
Marc,
You would need to move your boost control from a pin on the Megasquirt to a pin on the TIOx. This can be done on the MS2 (and other MS2-based ECUs).
If that's what you have, please post your msq for the MS2 and the TIOx and I can elaborate. It involves using one of the CAN ports as a PWM outputs. (If you look at the IOx website you can see the idea behind it but the screen capture pictures are for very old versions of the firmware).

Re: TinyIOx
Jean,
In attachment the .msq.
On the TinyIox AD5, AD6 and AD9 are free.
But perhaps first an explanation of what I want to do:
I want to experiment on our racecar with a wastegate actuated by a (rc) servo.
For this I need a PWM signal with a base frequency of 50Hz. The signal should be between 1ms (for 0% boost-output) and 2ms (for 100% boost-ouput).
I think the best solution would be to change the MS2/Extra 3.4.2 firmware, so I have the output as I would like it to be. I do not know if you can change the firmware?
If this is not possible, then I would use a work-around and translate the pwm signal to an analog signal and translate this analog signal to the pwm signal that I need. This translator from analog to desired pwm is already ready and working.
Translating the pwm signal to an analog signal with a resistor-capacitor filter brings a delay which is too big. I found a microcontroller driven translator which is very quick, but it needs a pwm signal between 1kHz and 3kHz. This is why I want a pwm signal of 2kHz.
Hope you can help me.

Re: TinyIOx
I would need to see your TIOx msq also. Are you currently using one or both of the PWM outputs (TPM2CH0, TPM2CH1)? If not, you can use them to drive an RC servo and you can use that with the boost control on the MS2.
Once I have the information, I can then go into the details of how to set this. It is basically what I mentioned previously plus the need to configure the PWM output and timer on the TIOx to use an RC servo signal.

Re: TinyIOx
Jean,
I did not know that there was a separate TinyIox msq. I suppose it is the one in attachment.
I am only using AD0,AD1, AD2, AD3, AD4 and AD8, the rest is free.

Re: TinyIOx
Marc,
You will need to set these things on the TIOx:
And on the MS2 you will need to set the CAN parameters and the Boost settings. I have not changed any of the boost settings differently from the defaults from your msq except for what is needed to use an RC servo on the TIOx but you will want to set things up the way you need it for the type of control you have in mind. Also, you will need to check which polarity you need depending on your hardware setup.
That should get you started. You will need to use a driver circuit for your PWM output. This can be a simple transistor output with a small NPN transistor, a base 1k resistor and a 1k 5V pull up; the current should be quite small so you can select almost any cheap component for these.
