PWM2 : the Frequency go out too on C5, C6 , C2 ....

I try to use the program PWM2 on C1,C2 pin connection and it's run fine on ISIS but on my EASYPIC 4 Programmer, i Find the Frequency out
too on The others C.pins.

Is there someone Who can help ME ?

Make sure your pullup/pulldown resistors are disconnected on PORTC. Since the resistor array is common there can be feedback to the other pins. This problem is resolved on the new EasyPIC boards with the individual pin switches.

Thank you XOR. this is the solution JP17 ON None. Even if I note a light escape of frequency. I think of buying soon the news "EASYPIC5" , because j' have to abuse the number 4 in my very first tests. Can be microphone short ciruits or some of the condosator to half Except Service.

Sorry My English is not very good....

I have used every board from EP2 thru EP5. Primarily EP3 and EP4. It is difficult to damage those boards. About the worst you can do is damage the CD4053 analog switches connected to the programmer circuit. I only know a couple instances where that has occurred.... when someone connected high voltage improperly. Even PIC's will survive much abuse.

THANKS XOR, Easypic 4 ==> JP17 ON NONE !
