; LCD Performance Measuring Application
;
; This is some kind of benchmark which helps to evaluate the performance
; of various character and graphical displays, as well as the execution
; speed of a custom LCD driver
;
; 16 characters are print 4 times (-> 64 characters), the execution time
; is measured with timer3, prescaler 1:8 - this means, that the counter
; result has to be multiplied by 8 and 100 nS (@40 MHz) to get the
; absolute delay
;
; The result will be print on LCD, but also sent via MIDI
; (F0 <hex-digit 1> <hex-digit 2> <hex-digit3> <hex-digit4> F7, MSB first)
;
; And here the results:
;
; Displaytech LCDs from Reichelt:
; o 2x16 KS0070B (HD44780 compatible): 3252 * 8 * 100 nS = 2.60 mS
; o 2x20 KS0076B/KS0063 (HD44780 compatible): 3177 * 8 * 100 nS = 2.54 mS
; o 2x40 KS0076B/KS0063 (HD44780 compatible): 3056 * 8 * 100 nS = 2.44 mS
; o KS0107/0108 based 240x64 GLCD (sold out): 6124 * 8 * 100 nS = 4.90 mS
;
; For reference: 2x40 with 4-bit interface, nearly no difference!
; o 2x40 KS0076B/KS0063 (HD44780 compatible): 3108 * 8 * 100 nS = 2.48 mS
;
; Various displays:
; o Matrix Orbital via IIC: 4612 * 8 * 100 nS = 3.69 mS
; o T6963C in vertical mode: 10647 * 8 * 100 nS = 8.51 mS
; o T6963C in horizontal mode: 37420 * 8 * 100 nS = 29.93 mS (!!!)
