FTDI USB to serial converters to drive SPI devices

FTDI USB-to-serial converters to drive SPI devices

Electronics News Updates / By

The FT232 USB-to-serial converter is one of the most commonly-used methods of adding USB functionality to small projects, but recently I found that these chips are capable of sending more than just serial signals. With some creative programming, individual output pins can be big-banged to emulate a clock, data, and chip select line to control
