VFD Module model-specific information
Timing Unit
Timing unit length varies between different modules. The timing unit length for each module display
dot size is shown below.
Timing unit affects the timing of the following commands and operations:
4.7.4.12 US s n (Horizontal scroll speed)
4.7.4.21 US ( a 02h t (Short Wait)
4.7.4.23 US ( a 11h p t1 t2 c (Blink)
4.7.4.24 US ( a 12h v s p (Curtain display action)
4.7.4.25 US ( a 13h v s pL pH (Spring display action)
4.7.4.26 US ( a 14h s pL pH (Random display action)
4.7.4.38 US ( f 90h m aL aH aE ySL ySH xL xH yL yH g s) (Downloaded bit image scroll display)
