//// This file contains drivers for using a Hantronix HDM64GS12 with ////
//// an LED backlight. The HDM64GS12 is 128 pixles across and 64 ////
//// pixels down. The driver treats the upper left pixel as (0,0). ////
//// ////
//// LCD Pin connections: ////
//// (These can be changed as needed in the following defines). ////
//// * 1: VSS is connected to GND ////
//// * 2: VDD is connected to +5V ////
//// * 3: V0 - LCD operating voltage is connected from a 20k Ohm POT////
//// * 4: D/I - Data or Instruction is connected to B2 ////
//// * 5: R/W - Read or Write is connected to B4 ////
//// * 6: Enable is connected to B5 ////
//// *7-14: Data Bus 0 to 7 is connected to port d ////
//// *15: Chip Select 1 is connected to B0 ////
//// *16: Chip Select 2 is connected to B1 ////
//// *17: Reset is connected to C0 ////
//// *18: Negative voltage is also connected to the 20k Ohm POT ////
//// *19: Positive voltage for LED backlight is connected to +5V ////
//// *20: Negavtive voltage for LED backlight is connected to GND ////
//// ////
//// glcd_init(mode) ////
//// * Must be called before any other function. ////
//// - mode can be ON or OFF to turn the LCD on or off ////
//// ////

//// with the given color. ////
//// - color can be ON or OFF ////
//// ////
//// glcd_rect(x1,y1,x2,y2,fill,color) ////
//// * Draws a rectangle with upper left point (x1,y1) and lower ////
//// right point (x2,y2). ////
//// - fill can be YES or NO ////
//// - color can be ON or OFF ////
//// ////
//// glcd_bar(x1,y1,x2,y2,width,color) ////
//// * Draws a bar (wide line) from the first point to the ////
//// second point. ////

//// glcd_text57(x,y,textptr,size,color) ////
//// * Write the null terminated text pointed to by textptr with ////
//// the upper left coordinate of the first character at (x,y).////
//// Characters are 5 pixels wide and 7 pixels tall. ////
//// - size is an integer that scales the size of the text ////
//// - color is ON or OFF ////
//// * Note - The given text is character wrapped. If this ////
//// function is used on a different size display, then change ////
//// the GLCD_WIDTH define appropriately. ////
