Ok thanks - I'll connect the opto collector tied high to the PIC and drive the Opto to GND - easy - no need then for ground resistors...
Thanks for R values..9547
I didnt do that - as you can see PARK for example - pin 15 - is the output of pin 16 when pin 1 is high. 15 is basically floating when not activated - I want the pin on the PIC to be active high -...
I'm using a 16f886 to detect digital inputs. I set RA5 for example to be a digital input. No analogs for this project.
ANSEL = 0 ' Make AN0-AN7 digital
ANSELH= 0 ' Make AN8-AN13 digital

Well I feel like an idiot.
I connected a 2.5 ohm 100 watt resistor as my load instead of the electronic load (5 amps).
No issues....works like it should. So the electronic (programmable) load...
The massive output FETs are to supply 12V to service vehicle equipment. Its an automotive environment, but - by the time it gets to my circuit, the voltage is isolated from the alternator noise, etc,...
My personality is hurry up and ask questions and get an answer. I need to slow down and think of my questions first and organize them. I want the asnwer in miliseconds - lol.
no no no - asking me...

see attached - do I own an oscillopscope I was asked? This is my proto lab.
I'm 67 years old who survived open heart surgery 4 months ago at NU hospital in Chicago, so not in the mood...
uncle.... do they have that expression down under? It means enough...
Is there a way to kill a thread?

here's rough schematic again - sorry for the wild goose chase guys - really appreciate the help.
Q2 is only driving the gate of some P channel mosfets. With the load attached to the drain...
The schematic shows it drives 2 P channel Mosfets which supply power to a resistor load. - the 10k and 6k on the collector drive the gate when the npn is on.
The odd thing about this is when it...
I should just say 12V, not IG - its 12V
yes - thats my test code
DC electronic load - it works at 1 amp - any higher it fails (PIC cant drive the base).. no noise - PS can handle 20 amps.. The base of the npn must be sinking too much current for the PIC pin to...

see attached - I changed to LATs as suggested but I still cannot drive the base of my npn with the load in. If I remove the load and turn the FET on - its ok.
I dont get it.

I need porta.2 to be a analog input - the rest are not analog - so how do I do that?
please email me if you can - easier to explain and I'd like to talk for 5 mins
Here's what I need
A0 - Led1 output
A1 - led2 output
A2 - Analog in
A3 - CLR
A4 - TTL Output to turn on FET
A5 - Input (TTL)
yout lat code worked but...
I used this
WDTE_OFF and it didnt come out of mainloop - worked
I also tried this
PWRTE_OFF - and I was able to write to my fet which had a load connected to...
didnt help..
OUTPUT PORTA.4
OUTPUT PORTA.1
HIGH PORTA.1
PAUSE 10000
mainloop:
ok - please elaborate..
I'll ask again - why does my program leave the mainloop?
porta.1 goes high and low..continuously
OUTPUT PORTA.1
OUTPUT PORTA.4
HIGH PORTA.1
PAUSE 10000
no - not a clone of MC3334P - it just turns on a load if IG is present.
by the time I get the IG signal its been filtered.
What coil?
IPB?
No current detection - just if IG is on (12V) and monitors battery voltage - this all working for past 5 years. Discovered the issue of no load it starts right up - with load it resets program. In...
