Hello, this is my first message to the list and I am very happy to have
found my way here - I want to get some opinions on an idea I have, to
find out if it sounds like I am on the right track or just barking up
the wrong tree! I want to use the FT2232H to drive a 2.4" LCD display
over USB. Using Channel A in asynchronous bit-bang mode connected to the
WR and RD pins on the LCD, sending 16-bit colour values for each pixel
(2 transfers per pixel in 8-bit mode). While simultaneously using
Channel B in MPSSE mode and utilising two of the available GPIOs to
drive the 'Chip Select' and 'Register Select' pins on the LCD. Here is
the datasheet for the LCD driver chip:
http://www.adafruit.com/datasheets/ILI9325.pdf
Does this sound feasible? Can I expect the two channels on the FT2232H
to be tightly integrated enough to have them cooperate in this way? and
still have a usable I2C port available on Channel B while driving the
MPSSE GPIOs at the same time?
And lastly, what sort of frame rate should I be expecting per second, at
153,600 bytes per frame? (240 * 320 pixels * 16-bits per pixel / 8)
Thank you very much for any advice and insight you can offer!
