right now all I have is just the two outputs being driven hi/lo. I commented out all the objects and use the xtal1 clock. The result is simply an output low with no hi/low response
Set pins for MosFet Drivers FOAM_Pin = 17
MIST_Pin = 16
I would write some extra code with delays at each step to send info to the serial terminal . That way you can step through the code. Are you able to disconnect the Mosfet and use your logic probe on the output pins to see if they still toggle with no load? If not are you able to output to different pins?
I am looking at the input of the mosfets, so I think we are good there. I disabled the serial terminal to really simplfy everything and it is on the xtal1 clock so i don't try to use the terminal. Just looking for an oscillating signal with my logic probe
Can you switch your output to 2 unusedpins that you can watch with your logic probe? That would tell you that the prop is working. then we could look to see what's keeping the mosfet low.
If the prop pin is connected to the MOSFET input , that would be normal. What we are trying to figure out is if you have the correct MOSFET that a propeller pin can switch with the voltage output it has or if something on the MOSFET side is holding everything low.
Is there anything in between the pop pin and the MOSFET , like another transistor?
Do you have a volt meter with you?
Did yo measure the power supply voltages?
Can you measure the voltages on the MOSFET ie gate , source, drain etc.
I had these mosfets being switched already before, the power is good from the volt meter. That is what is so difficult about all of this the hardware did work. Bob your up way past your bedtime , You did help me by letting me know the algorithm did work. It could be my logic probe isn't really working. Not sure. The mosfets have worked well and already driven loads.
I built my hardware, had the usb and the xb interface already working all the other sensors were talking. I drove up to Oregon to run an important test sensing and suppressing car fires and the boards I have slowly stopped working. I replaced crystals and processors on a couple no luck, Strange strange problem.

Yes, unfortunately I will have to go soon and probably without notice. It's 4:05 am LOL
It's probably one of those things that you will kick your self for later. LOL
You don't really need the logic probe if you have a meter however, what did you change? something changed? think hard Don't assume anything, just double check it all for example:
Did you pack the correct power sources with enough current? If your using battery's are you sure they charged up and they have enough current?
Figured it out thanks everyone, especially you Bob. It was so simple it was stupid. After Bob tried my code and it worked for him and not on any of my boards I realized I must be doing something so fundamentally wrong. So I went and tried to get a real nights sleep and got up ran some hex code and realized that I was not on my top object and was trying to load some older project in my boards. Soo stupid, it has been a long time between projects and I just wasn't thinking. All my boards seem to be working well so far this morning more testing to go, but way passed that craziness. Thanks everyone. Thanks Bob.
That's interesting because there have been raging debates about that "feature" in the Spin tools. It bites people often. The latest is here.
Certainly, well designed tools should make it very clear just exactly what is being downloaded.
That is also why text editors should show the full file path, (even if via a hint) so it is very clear to users, where they are.
(where I see this in tools, I get it fixed)

No problem Greg,
We knew you would figure it out after a good night's sleep.. I hope your event on Saturday went well. Your project sounded interesting. Maybe you can post some projects pictures sometime.
Hi Bob,
Sorry for the delayed response. I will get some photos to show, when I get a chance. All worked out, but it was many nights of little or no sleep

Do the expected pins change state on release of reset ?
Test1 Screen Shot
FOAM_Pin = 17
' MIST_Pin = 16 ' org
MIST_Pin = 18
I had to change one pin to 18 . However, that's probably a pin I killed some other time . It works on 2 pins if I use 17 and 18
I just tried it on 4 boards and a separate protoboard. nothing just low output. hmm..
What part Number is on the mosfet?
I am looking only at the input of the mosfets and on the protoboard just the pins - same result output low

That type of analysis.
outa [FOAM_Pin] := 1 ' If 1 then MosFet On
outa [MIST_Pin] := 1 ' If 1 then MosFet On
Try that to see if they switch on.
