> There is released code for 1/2 bias 1/2 DC as seen in the picklist. > It may be of help. http://www.piclist.com/techref/piclist/index.htm Yes, thanks very much, it is helpful But ;-) I was hoping to use the F628 or similar, but the I/O count is too high, (forgot about the anti-phase COM) so it'll have to be a larger PIC. I'll need to look into prices, MOQs etc else it defeats the intention of cost-cutting, not just doing it a different way for the same money, sigh However, I'll definitely investigate your project with an F877, and to make it all worthwhile look around for the best/biggest bang-for- buck clock-style LCD. If there is to be any increase in costs then it should be where it matters to the user -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY!
