Honored Contributorhi guys ,i'm creating a uart with even parity error and frame error ( serial one ) for cyclone EP1C6Q240 and i'm looking for an LCD controller , does anyone knows where i can find one for this project ?
Honored Contributorif you are looking for a lcd controller, you must know the lcd this controller should control.
there are so many different lcd's out there and most oft them have a different interface and / or command set. withou this information is like asking for spare parts for a car without telling what car or even what manufactur it is.Honored Contributori believe its :
hd44780u (lcd-ii) , which they use on cyclone ep1c6q240 , education kit.
thanks mschmitt , i'm a bit new to this.
Honored Contributorokay that is an character lcd with up to 4 rows and 40 colums, made by several manufactures.
the interface is very easy, as it is just like accessing an external register (or memory) all you need after connecting the lcd to your fpga is to enshure a correct initialisation sequence of the cld and then just write the characters. there should be lots of information about that lcd type availableHonored Contributorthe problem is that i cant find any LCD controller that based on a "busy flag " all i can find is a controller that based on clock and other component but not on the LCD busy flag ....:(
