> As mentioned before you should put resistor between the output and LED. I'll try without _XT too, as soon as I buy the resistors. I'll buy a bunch of resistors xD someone have any explanation for all that resistors ? I don't understand why they are necessary õ.o If things remain wrong, I'll try that.Īgain with resistors x_x 1K resistor to MCLR, ok, I'll try that too. I thought that maybe I was supose to put RA6 and RA7 as inputs ou CLKIn as input and CLKOut as output, but I'm not sure. The resistor again :S I'll buy it today, it may be that, then. You could disconnect the crystal and try _INTRC_OSC_NOCLKOUT instead of _XT in the config. I'm not sure if RA6 and 7 have to be set as inputs for the external crystal to work.Ī 1K resistor is recommended between MCLR and VDD but I'm not sure if it will make any difference. > I can't see anything too obvious apart from the missing LED resistor.
I don't understand why I have to put a resistor there, but ok, I'll buy one today and test it. Well, he still reads and writes, that's a clue that he's still working ? That's true ? how the resistor in a out pin of the microcontroller would screw the microcontroller itself ? > Man, if you don't put a resistor to limit the current to led, maybe you screw the led an pic, too.
