The Hammer supprts an LCD interface which can be configured to drive various kinds of displays. The following is how I wired up a 16 shade greyscale, 4 bit single scan, 320 x 240 LCD panel.
I used a Sharp LM32K10 display panel.
The above schematic uses a 74AC244
The driver interface can be done with either:
The source of V- is left to the user, this panel requires about 7-10ma at -18-19VDC.
I used an *NMA0515S with the V+ connection grounded, so its output is ~-30VDC at up to 33ma.
The following circuit drops the -33V to -18V for use by the LCD panel.
The transistor I used is a 2N3906 but any PNP device that can handle 100ma collector current will do.
The Hammer signon message displayed on the LM32K10 LCD panel.
LCD's that can be used with the Hammer using the same interface:
Other LCD panels with built in controllers that could be used with the Hammer(These panels have an on-board controller and do not use the S3C2410's lcd controller):
