The SLCDx controllers can run either 8-bit color or high-color firmware (the original SLCD is 8-bit only, for high-color, use the SLCD+). In 8-bit color firmware, when a 24-bit “exact” palletized image is displayed, the bitmap routine maps the 24-bit color to the closest available in the fixed SLCD palette. In high-color firmware, the BMPload program converts 24-bit color bitmaps to 16-bit color (RGB565 format) before storing them on the controller board.
