thanks.
Hopefully it just means the oscillator will possible be slightly different than 4mhz if there is less voltage. I guess I'll find out soon enough
I think its indicating that it will not oscillate.
There is also an external clock pulse available on the same connector as the binary outputs, I'm unsure of the frequency (i'll check)- if it comes to it, I suppose I could use that to synchronise all 4 pic chips and just use 2 (more powerful) transistors to switch all the displays, rather than 2 per display.
I would guess that trying to sync 4 PIC's is a no,no.
- Anyways- I'll try it with the 3.3V and hopefully it will be forgiving enough.
Still annoyed I got wrong chips sent- but too eager to experiment rather than sending them back
I know exactly what you mean
