It's unlikely the display can be connected directly to the FTDI chip due to the extra control signals required to operate the controller(s); CS1-CS2, C/D, and E. Others have used a microcontroller for control logic. A shift register could also be useful. |

I have been trying to figure this one out too. I think it should be possible. The trick would be to multiplex the I/O lines in such a way as to provide a fast but usable interface. I would split it thus: Code: FT245R D7=0 D7=1
D0 D0 D4 D1 D1 D5 D2 D2 D6 D3 D3 D7 D4 R/W CSA D5 D/I CSB D6 E-LCD W-BUF E-LCD is the LCD enable pin, W-BUF is a hex buffer write pin. In fact, it might be possible to speed things up by using the FT245R's RD line, which strobes as data is written. It might replace D6, meaning only two writes would be required to write a byte to the LCD. A pair of hex buffers and some logic would be all that is required. |
