Re: RTC

Update: If you look at the 2010-2011 version of the datasheet for the MCP79410 or MCP7940 you will see they recommend a capacitor on each crystal line and a capacitor, resistor and schottky diode on the battery line. The DS1338 doesn't need those five extra components. Fortunately I found this out b...

Re: RTC Software

Noooooo don't use a DS1307 it needs 5V and if you connect it to 5V then the I2C lines will be 5V which can blow your Pi!

Re: Fitting the display on a TV: config.txt and overscan_*

I don't understand, with digital output I would expect if the screen had the native resolution of the output, shouldn't it give you one to one pixel matching?

i.e. fill the screen automatically like a DVI monitor or a laptop.
