Re: Undeletable "Variable Never Used" (help please)
Thanks Horace! It gives me a good idea about what is happening but I still have some dificulties to solve it. I just declare the variables like this:
unsigned char Ignition_Flags;
unsigned char Ignition_TimeOutCounter;
unsigned...
Hi there! I need some help to solve this problem...
I´m using MPLAB 8.87 with CCS Compiler 4.114 to create a software to a PIC16F1829. The program has about 5000 lines and already works perfectly. I was asked to delete an old funcition and create a new one. Ok! Deleted the old one and...
I already tested some high side drives and PROFET™. They are really fantastic devices but my application can't afford its costs. Due to this fact, I had to implement an analog circuit to protect Mosfets.
The circuit suggested by grittinjames: worked just fine after some adjusts.
It takes 200...
I already tried some similar solution. I can't use this "shunt" resistor (0.01 ohms), cause the car lamp and its ground are far from my circuit.
So I tryed a uC pin to read the overload, but I think I did it in the wrong point. Could detect overload and act in 80 us but MOSFET didn't turn off...
Good afternoon,
I recently changed a relay to a MOSFET channel P to reduce space and silence the application. The same pin of microcontroller drives mosfet through a totem pole connection. Mosfet switches a 40W DC lamp. Until this point everything works fine.
The problems is: when the lamp is...
