Hi! Thank you ! I will retry with the last design available then. In the meanwhile , i checked the traces and it seems ok with the last official, so i can say it should be ok..
I heard the tone only without fuse setting...
Maybe something i do wrong in setting those ones?
I changed Crystal, progammed with tl866 and with usbasp. I'm using atmega88pa.. Using 0xe0 as low and 0xdf as high fuses. No change to extended..
Can you suggest me a configuration (fw and fuse) that should work for sure?
