But the controller on the Sparkfun <a href="http://www.sparkfun.com/products/9363">Color LCD Shield</a> seems to be Epson S1D15G00. So I made a quick port of this <a href="http://peterdavenport.blogspot.com/p/lcd-library.html">"Library"</a>, (it's not a Arduinoish Library, more like an example sketch).</p> <p>The controller (as it's used on the shield) uses 9bit SPI, so I just ported the code by simply doing<br /> <pre><code>#ifdef BOARD_maple // Maple bit numbers and ports #define LCD_RES 10 // GPIOA.10 = D8 #define CS 7 // GPIOB.7 = D9 #define DIO 7 // GPIOA.7 = D11 #define SCK 5 // GPIOA.5 = D13 #define LCD_PORT_CS GPIOB_BASE #define LCD_PORT_SCK GPIOA_BASE #define LCD_PORT_RES GPIOA_BASE #define LCD_PORT_DIO GPIOA_BASE #define sbi(port, bitnum) ((port)-&gt;BSRR = (1&lt;&lt;(bitnum))) #define cbi(port, bitnum) ((port)-&gt;BRR = (uint16)(1&lt;&lt;(bitnum))) #else ...</code></pre> <p>So it's bit banged directly on the port registers. The serial clock will be about 1.8MHz (a little faster than shiftOut() :-)).</p> <p>You can find the ported sketch <a href="http://idun.homeunix.org/LCD_Library_maple.zip">here</a>.</p> <p>Maybe I'll do a real Arduino style library for this shield some day.<br /> (And I don't only write LCD code ;-) </p>
