Re: [Flashforth-devel] RTC PCF8563T driver

[om1zz <om...@vo...>]

Hi, 
if somebody seeks a driver for popular PCF8563T RTC (with lowest backup current consuption (200nA), afaik) you may find it at:
https://github.com/igor-m/EXPERIMENTAL_FF/tree/master/examples
Needs an i2c low level driver, for example from PeterJ for pic24.
Igor
