If I were to increase the clock rate to 16MHz (currently 8MHz), it will probably disappear. But to do that, I need an external clock, or xtal. One or two more IO bits that I don't have in its current incarnation.
I almost managed to get it coded inside 4K, which would allow me to use a ATmega48 chip, But that trimmed too many features. Currently the code size is about 5.5K. -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
