Blinking an led problem on P16F84

[aimenbukharie]

I am working on P16F84. I want to blink an led. I have a problem.

1. After having all the connection,the voltage at the output port of P16F84 is 0.5V and when the led is connected, the voltage drops to 0V. I am confusing that why the voltage drops even the voltage supplied at the VDD is 5V and MCLR pin is connected to 5V.

Most likely you forgot to initialize the TRIS registers and the ports are in a high impedance mode. Put this into your code and post your code if it still does not work.


TRISA = %00000000 ' make all ports outputs
TRISB = %00000000 ' make all ports outputs

I did that myself last week :D
