# icoBoard with Digilent Pmods support
|
|
|
|
This adds support for building the apple one design for
|
|
[icoBoard](http://icoboard.org/about-icoboard.html) with attached Digilent Pmods
|
|
for VGA, PS/2 or UART.
|
|
|
|
## Peripheral support
|
|
|
|
VGA port is working through a Digilent VGA Pmod on Pmod 1/2.
|
|
|
|
PS/2 works through a Digilent PS/2 Pmod on Pmod 3 upper row.
|
|
|
|
UART works through a Digilent USBUART Pmod on Pmod 4 upper row.
|
|
|
|
By default, UART is enabled (and PS/2 is off), check
|
|
