For overclocing needs, the pulse times MEASURED on the sign were:
|
||
|
|
|
||
|
|
0:
|
||
|
|
high: 294ns
|
||
|
|
low: 954ns
|
||
|
|
|
||
|
|
1:
|
||
|
|
high: 626ns
|
||
|
|
low: 618ns
|
||
|
|
|
||
|
|
|
||
|
|
The HIGH pulse times are always the same, the LOW pulse times are shortened by increasing frequency

Current speed 800Khz
|

|
|
494 LED theoretical maximum framerate:
|
||
|
|
1/((494*32)/800000 + 80e-6) = 50.4Hz :(
|
||
|
|
|
||
|
|
925KHz is still fully in spec of the LEDs and provides:
|
||
|
|
58.2Hz
|
||
|
|
|
||
|
|
955KHz is only slightly out of spec and proviced a smooth
|
||
|
|
60.1fps
