Re: issue of RAMPS-FD LCD adapter (with smart controller)

Hi all

I find out what happend of this issue (I guess so ) ....The reason of lcd adapter not working is is the firmware can not handle the LCD RS signal .....LCD RS on mega2560 is working good ,but on due not woking good ,the signal seem has random noise .... I have try 3 solutions :1) make a lcd adapter with ic 74hc07 (nxp product , totally new !) 2) check the signal without RAMPS-FD ,mainly check D16 (LCD RS ) and D17(LCD E) ,I find out that D17 working good . 3) I changed D16 to D23 ,in order to make sure that not some function of the MCU make the signal has random noise , the result is the same as D16 . Of course I also check D16 D17 D23 are not broken with arduino IDE exsample programe "blink " ,I changed io and make delay down to 5mil seconds (in order to make a square wave ) .
base on above ,I think the Repeter firmware for due has some issue on this .... Of courese ,this conclusion is not confirmed by repetier , so I need you guys helps ,Dose anyone make the lcd working good with RAMPS-fd on due ?pls let me konw .THX lots !(:P)
