I already ordered that but I will get to late for the current urgent project. So my request is the next: please check with a multimeter the connection between the pins marked with red (control signals) and the adapter pins. Please note them, and also please draw a wiring sketch with the connection of the components from the adapter PCB (I'm sure they are connected on the control signal for inverting a signal for example). The rest of the signals (Data/scriptddress/Power/Vpp) I already fixed, I have problem with the marked pins. Thank you in advance, best regards, Feri [b]Image Insert:[/b][br][img]http://www.mcumall.com/forum/uploaded/uferi/20149226161_87c510_sketch.JPG[/img][br][size=1] 40.17 KB[/size=1] [b]Image Insert:[/b][br][img]http://www.mcumall.com/forum/uploaded/uferi/201492262353_ADP-063_V2.0.JPG[/img][br][size=1] 111.35 KB[/size=1] [/quote]    Insert an Image File Check here to include your profile signature.
