The full-monty bare modules are rare, expensive and unavailable.

Some libraries are VERY inefficient, and take 100s cycles per 16-bit. Has anyone found one that uses the SPI if Or even a 16-bit one that can change the mode bits for SPI. But 6 bits are in one port and 2 bits are in another port. Oh well. It will be replaced with a new version called ET024008DHU in mid 2010 that have the same outline dimension and same electronics and optical specification. Open-Smart Tft Lcd Shield Hx8352B Projects Source Code Serial SPI InterfaceThis controller provides several communication interfaces like 816bit parallel MCU interface, 1618bit RGB, and 4-wire serial SPI interface. On the Display Xplained module this has been hardwired to use serial SPI interface. I got mine from iteadstudio, but it seems they have discontinued it. I found the redraw of the screen a bit slow on the Arduino, so i ported the code to a lpc1769 and cranked the spi up to 25MHz. Much quicker, but still slow for anything reasonably dynamic. I should be able to compare speed with the larger 320x240 8-bit display. It seems to be massively overpriced compared to the 8-bit or 16-bit modules. They have a kentec qvga display that has the mode selection pins available on the flat cable. An enterprising shield maker could produce a shield that works with both UNO and Mega. Due, Mcrochip clones,.). You can use a UNO or Mega adapter shield to enable Arduino convenience. Not as practical as a single shield, and of course uses most of your GPIO. When my 1.8 SPI module arrives, I can see for myself. China Post going to be 9 days or 35 day wait ). Open-Smart Tft Lcd Shield Hx8352B Projects Source Code Plus 28 ForAfter a while I realised that a 35 Mega 2560 Freaduino, plus 28 for TFT 400x240, plus a 7.50 shield, provides a fast interface, an AVR with plenty Flash and Ram, touch and SDslot. Now consider Cliffs suggestion: an AVR backpack, which provides SPI interfacing to a host. I dont see how that could be done, considering the need for a pretty large AVR. ![]() Surely they could bring out all 60 lines Or possibly just 10 odd lines for SPI. When my 1.8 board arrives, I will see what size ribbon was used. I hope). I might try it all the same. HC595s. Since the driver chips already have SPI option, it seems cack-handed to add SPI to the parallel externally.
