The programs in the exesrc directory are old snippets that I used for testing, once upon a time.
They're mostly useless, but I've left them in case someone learns something from them.

The "set_leds" program assumes LEDs are connected to a GPIO in the FPGA, and the GPIO is at address 0xA00C0000.
The data for the GPIO is read/written from offset 0.  Input/Output direction of the GPIO is set at
offset 1.  A 0 for a bit means it's an output.
