Hi all
I am trying making a ramps-fd lcd adapter ,bobc give us a very nice solution ,in bobc's solution ,the adapter change the logic voltage with 74HC07A .I make some change ,I use 74LS07 and 7407,and then some issue come out .... the lcd not working ...So I try to see what happened ...here is some results .

FOR arduino mega2560 smart controller adapter 2004 LCD working good ,here is the screenshot with saleae logic 1.1.15

screenshot above is lcd adapter with ic 74LS07 ,the signal of LCDE is not working normally...

adapter with ic 7407 ,the signal of LCDE is not working normally either... signal has some random noise ,so lcd can not tell when should begin to work..

I have check lcd's schematics the signal voltiage is converted by ic 74HC07A ...
SO I wounder that 74HC07 can be changed by 74ls07 or 7407 ???
