Background: I'm using an MS3/3x on a 3.0 board, firmware 1.3, but will upgrade to 1.5 soon (been running a few years). I've loaded the TinyIOx ini file into TS, seems to have reconigized it in the TS settings. I will be adding a MicroSquirt transmission controller at the same time.
Question: Every input requires conditioning? I'm 95% sure they do, just want to be 100% sure. I plan on adding some temperature and pressure ADC inputs.
Copying/paraphrasing from the other thread:
Second question, PWM out frequencies. TS indicates they are limited to the same range as the MS3 has available, to get frequencies upwards 2000hz do I need the PWM converter board? Or can the TinyIOx do it on it's own and I'm just missing something in the setup? It would be feeding a solid state relay to run a pump motor (Dorman #902-303). Side question, if I need the PWM converter board, would I be better off sticking with INJ2 output that I am currently using, as opposed to putting it on the TinyIOx output, and just add the converter board?Is this the correct circuit for the temperature sensors? (three circuits shown) And... just omit the 2.49k resistor for the pressure sensors? Is the 1M resistor needed for the TinyIOx?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.
Is there any reason that I couldn't assemble these circuits "in-line" with the sensor lead wires and shrink wrapped externally to the potted TinyIOx, instead of on the prototyping or other board?
