When working with FTDI the chip encapsulates the USB protocol The only interface are the control RD WR RXF TXE and data lines Here the initialization procedure consists of 1 switching RD and WR to output pins internal pull up s enabled 2 set RXF TXE and data lines as input pins 3 optionally empty USB FIFO buffer by performing dummy reads Data bytes available for reading are signalized by RXF being L as long as the buffer is not completely empty A byte can be read by toggling RD from H to L then get the state on all 8 data lines and put RD back to H level Writing bytes is performed vice versa First check the level on TXE If it is H the transceiver is busy or the internal buffer is full Otherwise the transmission may start by setting the 8 data lines according to the transmit byte then toggle WR from H to L and back To improve per formance writing should always be done block wise The octal bus driver is automatically enabled by the internal USB CE signal if at least one of the RD or WR goes L means reception transmission in progress On the other side you should ensure that RD and WR are permanently driven H if you do not use the USB over FDTI to prevent the bus driver energizing back the FTDI circuit For simplified detecting whether a USB cable is plugged or not the VBUS signal may be used active high On the FTDI variant this only works reliable if RD and WR are driven H The device driver required
