ATtiny13 communication problems

Development Boards MicroMod
1

I bought the ATtiny 13 and a development board thinking that the Tutorial Lecture 2 - How to Get Code Onto a Microcontroller would work for it. I thought I would start small and it would be easier and less complicated. But I get something that looks like this.

avrdude -p attiny13 -P COM1 -c ponyser -U flash:w:blink_1Mhz.hex

avrdude: AVR device not responding

avrdude:initialization failed, rc=-1 double check connections and try again.

Well just for kicks I just tried it again with my new 9Volt power supply and it was able to communicate. For some reason a 9v battery must not be strong enough.

If you hold it the dongle connection just right I can get it to communicate. That’s the good news. The bad news is the LED doesn’t blink. What’s the chance that it’s blimking too fast to see?

i don’t see a command for programming the fuses in your avrdude command line. Make sure you are programming the fuses correctly. I am assuming that you are using the internal clock in the attiny13.

you can read the fuses with avrdude to verify that you have the correct settings. if you don’t know how, check out the avrdude page to find the command.
