The TS-4100 FPGA registers are accessed over I2C. The /sys/class/gpio driver provides access to the IO using these registers. See the #GPIO section for more information on the recommended method for IO access.

The FPGA is available at I2C addresses 0x28-0x2f. First write the address which is 16-bits, followed by the data which is 8-bits.
