Olimex iCE40hx8k-evb support
This adds support for building apple one design for Olimex iCE40hx8k-evb board with attached Olimex iCE40-IO extension for vga and ps2
Peripheral support
VGA port is working trought the iCE40-IO expansion.
A usb-serial converter can be attached on pins 5(RX), 7(TX), 9(CTS) on either the iCE40-IO extension or witout it directly to the header of the FPGA board (pin out is the same). Consult the schematics for iCE40-IO and iCE40HX8K-EVB for extension header pinmap.
The iCE40-IO board has a ps2 connector you can use if you have a ps2 keyboard but it's not edded to the design pin map.
This port is using 1 PLL for generating the target 25Mhz clock.
Building
Install a recent IceStorm toolchain, and:
make
Use
There are 2 possible ways for flashing the board:
To load BASIC type "E000R" with CAPS LOCK on.
