Nothing connecting to them. I thought the config word I used,
11 1111 1111 1000, set it up for internal osc, no? I'll try using the
ext RC. Like I said, I'm a newbe to this, though I've been using a
BasicStamp and a 8051 with SDCC for a compiler. I've also used a
robotic controller using an 18F8722 with MPLAB 7.2, though all the
setup used pre-written code.

What about the OSC pins ?

Silly me. I'll try it again.

Do I do anything with MCLR? I only have Vss,Vdd and pin 7 connected.

You didn't say which package you are using, but if you're using the DIP
or SOIC package, then pin 7 is RB1 but your program is setting RB0. If you're
using the SSOP or QFN package then pin 7 is in fact RB0 so it should work
assuming no loose connections or LED connected backwards, etc.

Can't get it to light a LED. I'm using MPLAB with CC5X compiler and
WinPIC programmer with an RCD programmer. Here's the program:
Compiles and programs with WinPic ok.
void main( void)
{
OSCCON= 0x7C;
PORTB = 0x00;
TRISB = 0x00; //outputs
while (1)
{
PORTB=1;
}
}
Here's the configure word from WinPic:
Internal RC osc, WDT Disabled: 11 1111 1111 1000
Using an LED and 330 ohm from pin 7 to gnd.
Any help?
