Need Help Programming a ATTiny13 with a Olimex AVR-P20-10MHZ Developement Board

Development Boards Other Microcontrollers

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.

Are you certain the replaced regulator is in the correct orientation? I’m worried about it since the LED isn’t lighting @ power

Trying to use Arduino as ISP was my other idea, as the Olimex board uses ISP/SPI protocol, not serial/UART. You can’t program it through a simple USB-to-serial converter with baud rates.

Do you happen to have another programmer?

  • USBasp
  • USBtinyISP
  • Arduino as ISP (which you tried)
  • Atmel ICE
  • AVR Dragon?

Also, the code looks good to me except the ATtiny13 ships with internal 9.6MHz oscillator divided by 8 = 1.2MHz default, not 1MHz. You might want to set $crystal = 1200000 or reconfigure the fuses
