Signals
This is the signal-mapping, when using 16Bpp displays. 18Bpp is not supported in the current Windows CE drivers for Trizeps IV(M) and Trizeps V, because of it many disadavantages compared to the win of 2 extra display-lines. If needed LDD16 and LDD17 are mounting options on pins 150 and 152 of the Trizeps-module (Trizeps IV(M),Trizeps V). Trizeps VI can support 16, 18 and 24Bpp. Note that LDD18..23 are used by the Trizeps VI onboard uSD slot and can only be used if no uSD card is inserted.
If more display-lines for each color are availlable for a display, connect the unused LSB-bits to ground. Usually displays also have additional control-lines for backlight and power. See bitmapboot on how to configure those options; i.e. backlight-PWM or power-enable GPIO's. Some smart-displays might also require special init-sequences using SPI or I2C. Contact Keith & Koep for more information on how to handle those.
