Reading in Data using a microcontroller

[ash]

If you'd like to construct in on a bread board, you may refer to a schematic here:

Its for a line follower robot, but you should be able to follow it without problems. Just ignore the motor driver schematic

Let me tell something..

While using the External Oscillators, we need to set the Oscillator Registers for Type of Oscillator we are using, Baud Rate setting etc..

This should be done in the Program while initializing...


Check out the Transceiver connections and Rx/Tx pin settings in Controller.

I'm still having trouble getting the PIC to work after following your diagram. I connected pins 11 and 32 to +5V like it shows. I also tried connecting pins 12 and 31 to ground. My clock circuit is a bit different though. I'm using a 4 pin crystal oscillator. One pin on the crystal oscillator gets connected to +5 V and one pin is connected to ground. Then there's one pin that isn't connected and one pin that gives the clock signal. I ran a wire from the output of the oscillator to pin 13 of the PIC. I left 14 unconnected. For Pin 1 I tried both connecting it directly to the +5 V source and using a 10K ohm resistor. It's really strange. The PIC works fine when it's in the programmer but I can't get it to work when I use it in a breadboard.

Oh, I'm not sure about 4 pin oscillators. The pin thats not connected is the "enable", yea? You either float it or connect it to VDD to enable the oscillator. Does connecting it to the +5V make a difference?

If all else fails, try getting a 2 pin oscillator.
