What to learn more about controlling the common FTDI FT232 and FT2232 chips from a PC? Daniel shows how to drive a shift register with the FT2232H breakout board under Linux. This basic app can expand to control large projects that need lots of computer scripted outputs.
Control an 8bit shift register over 3 pins from an FT2232H device: DATA, CLOCK, LATCH. Whilst LATCH is low, high/low DATA and CLOCK 8 times, then raise LATCH to high – pins change state.
