I thought I could do this without help, but I need to find a good tutorial, or a push to get going. Here is my program.
$crystal = 1000000
Dim X As Byte
Config Portb.3 = Output
Do
Toggle Portb.3
Waitms 200
Toggle Portb.3
Waitms 1300
Loop
It compiles OK, but when I send it to the chip, nothing happens. I had to replace the LM317T regulator on the board, but when I apply 12 volts to the board, the LED does not light up. I set the chip voltage to 5 volts and have the 3.3v shunt unplugged. I am using an older Keyspan USB to serial converter, and I am assuming my baud rates are suspect. I have everything set to 9600.
Please help me where to look. I am trying to keep this simple as I have been unable to program the chip using a Arduino Nano.
Thanks for your help.
Ummm, ATtiny13 doesn't come in a package suitable for AVR-P20-10MHZ...

You are correct. I added an eight pin socket and correctly ran wires from the existing socket to the eight pin.
THanks
I am also running BASCOM AVR Demo
Describe the exact connections between the target and the AVR-P20, maybe I can spot something wrong.
Maybe also test with avrdude it should have support for STK200.
I have tried installing AVRDUDE. I don't know how to run it.
Pin 1 to pin 1
Pin 10 to pin 4
Pin 17 to pin 5
Pin 18 to pin 6
Pin 19 to pin 7
Pin 20 to pin 8
If I could post a pic, I would.
This project is so simple but I can't get through it.
If the Olimex board's serial port isn't the way, how else do I get the chip programmed? I am limited in space and this footprint is about all the room I have.
Thanks
You can host the picture elsewhere and provide just the link here. There are a lot of free image hosting web-sites. I use imgur.
