Easylogger (ATtiny45)

Post by Lars » Wed Jun 23, 2010 11:22 am

Hello,

I made the Easylogger and when I push start button the LED burns, but I get nothing on PC (Ubuntu and on Windows it says it doesn't recognizes it). I think my clock is wrong?

I programmed the chip with the main.hex in the zip file, with USBtinyISP.

What to do?

Greetings,
Lars

The shear number of things that could be wrong is huge
The number of people on this forum is not

You definitely did not provide enough details for anybody to help, I myself am not familiar with the PLL clocks of the ATtinys... but double check your clock and compilation settings by running a LED blink, once per second using util/delay.h for a minute, you'll know if it's wrong if it blinks too fast/slow.

I had the data lines wrong (green/white) and I had to use this:

-U lfuse:w:0xe1:m

Now it is working! :D
