Nope, it doesn't work... :x
Lolita, just a question: few days ago you said:

The display is definitely the right one for your player, but the connectivity might not be correct...
But the first line of the script is:
Code:
o 2 18  ; select CE3
CE3? But should not be CE4?
Also: S1MP3 Wiki says:

"chip select lines are active low. It is usually connected to CE3- of the SoC, although there have been schematics of players that have it on CE2-, CE4-, or even CE5- (in the case of a particular ACU7515 design)."

Indeed in this ACU7515 schematic the CS of the LCM is connected to the CE5 pin.

So I was thinking: it can be that the LCM can't oscillate because it isn't connected to CE3, and the first command does nothing?
