Sebastien Bourdeauducq ea63389823 fhdl: support len() on all values 2013-04-14 13:50:26 +02:00
Werner Almesberger 7a6e56492c edid.py: sample SCL only every 64 clock cycles, to avoid bouncing 
Possibly due to SCL rising fairly slowly (in the 0.5-1 us range),
bouncing has been observed while crossing the "forbidden" region
between Vil(max) and Vih(min).

By lowering the sample rate from once per system clock to once
every 64 clock cycles, we make sure we sample at most once during
the bounce interval and thus never see a false edge. (Although we
may see a rising edge one sample time late, which is perfectly
harmless.)

Werner Almesberger 59d64e92e8 mibuild: define memory card pins of the Milkymist One platorm 
This patch adds the memory card pins to the M1 platform definition in
mibuild.

I've tentatively named them "mmc". As far as I can tell, "MMC" is not
trademarked ("MultiMediaCard" the new "eMMC" would be), and "MMC" is
commonly used in the industry in a descriptive way to refer to this
sort of interface.

The original Verilog-based M1 calls the interface "mc", but since
several names have changed between milkymist and -ng, I thought I'd
use a more familiar name.

Usage example (clock signal divided by powers of two on the MMC TPs):
