Post subject: | C# problem with HD44780 and DLPortIO |
Hi all, im afraid in need for some help ![]() since a few days im expermenting with a HD44780 in combination with C# and DLPortIO. My goal is to write a program which can display text on my display. I used a program called LCDSmartie but since that is not completely to my satisfaction i got the idea of writing my own program. because im fairly new to LCD/VFD programming i started by searching the net and one of the biggest dissapointments is that there arent many clear examples of c#source available and im not that "good" with c++ i found some vb.net code started up visual studio.net "rewrote" the code to c# (using the DlPortWritePortUchar function of DLPortIO) and made a little test form with a button on it. I got some output at my display fairly simple but experienced some "weird" behavior though. one of the problems im having right now is that whenever i try to output a string to my display it appears for a sec and right after that my display darkens to be empty like just before ![]() whats even more strange (at least to me..) is that after the initial display of the desired string i cannot reproduce the same again, when i click the same button again the display wont show anything ![]() does this ring a bell to anyone? |

i was aware of the article at code project, only difference is that i want to use DLPortIO instead of inpout32 (or something like that). what i can do is test if the source of the codeproject solution gives me the same problem thanks anyway ![]() |
