FPGA Clock Settings

These commands are available three ways — in the FREE-WILi GUI app, in a serial terminal, and on the device itself. See Connecting it to a computer for how to reach them.

Clk Source

Choose the clock source that drives the FPGA (CPU clock, oscillator, USB, or RTC)

How to use it — press c.

What you enter — value.

Clk Divider (int)

Set the integer part of the clock divider used to derive the FPGA clock frequency

How to use it — press i.

What you enter — value.

Clk Divider (Frac)

Set the fractional part of the clock divider used to fine-tune the FPGA clock frequency

How to use it — press f.

What you enter — value.

Comms Mode

Choose whether the CPU talks to the FPGA configuration registers over SPI or I2C

How to use it — press m.

What you enter — value.
