I'm trying to connect this newhaven lcd screen to my arduino. http://www.newhavendisplay.com/index.php?main_page=product_info&cPath=3_111&products_id=1828
I thought this was an SPI device, but I don't recognize how the pins are labeled. There's a serial input (SI) and clock (SCL) and chip select (CSB) but then there's no MISO pin and there's this "RS: Register Select Signal. RS=0: instruction; RS=1: data" pin. I'm not sure how to connect that, and I'm also not clear whether I can use the standard arduino library for SPI. Anyone used this type of interface before.
