Worst case you can increase your resistors or reduce the operating voltage.<br /><br />But why do you want to switch to bascom. Have a look at my pattern routines an then write your own. It is not too complicated.Tom F.https://www.blogger.com/profile/17222198163820671255noreply@blogger.comtag:blogger.com,1999:blog-5485549003242897389.post-53892625829097590342014-05-20T09:22:08.242+02:002014-05-20T09:22:08.242+02:00Hello i built your cube with Atmega8 without L, so...Hello i built your cube with Atmega8 without L, so i put 47 ohm resistors on blue lines and its working perfect. I only got one question. Im trying to make my own program in bascom avr (assembler) so im wondering about dimming function.

Due to the multiplexing scheme used here, up to 8 LEDs need to be driven at the same time. The controller can't do this. So I needed to add a stronger driver.<br /><br />Effectively the drivers consist of 8 transistor switches. Take a look at the data sheet.
