    AVR HVSP Fuse Resetter

    Yes I set the fuse as per instruction. In that case, I might have to learn how to fix the multiplexing in the code :)

    Hi there :)Thanks for the quick response! Your explanation about the mapping was very helpful to understand by the code. Also, I tried commenting #define _REVERSE with having the same setup for the characters for common cathode LED but to no avail. I'm only getting the first digit all lit up and pushing the button doesn't light up anything. Pushing it long to reset gives a dash at the last digit. I guess it must be the display problem. Haven't tried commenting other blocks but will try to understand first how to display in LED by debugging it through Blinky. Thanks a lot for your help!

    Hi there,Did the wiring based on the source code and also changed the hex assignment of the characters since I'm using common cathode 4x7 segment LED instead of common anode as per suggestion but still can't get it right. In fact, I'm actually wondering how does assigning SEG_D_PD to _BV(7) actually maps it to PA1 in the attiny? This is also true for SEG_d_PD_BV(6) as per definitions. Is there anything else I need to change in the code to match the operation to a common cathode 4x7 seg LED? Looking forward to your insight, thanks!
