hi everyone! i got the SED1520 from somewhere(made in china, original model is SMG12232A). i was trying to control it using MPU but i don't know it works or not. i've tried lcdinfo and the result like the one above there are two black lines in the middle with fews pixels normal. i found that all the pixels on the screen can work correctly since sometimes it will mess up. after that i tried to load a picture to test the lcd again(as below, because i should plug on the board so it was up side down). it cannot show the upper-left corner. what can i do or is the screen damaged? the 'good bye!' message can show correctly i use IC555 as the 2khz clock and i didnt make the contrast adjusting circuit i want to control it by the 80 family MPU, any code samples? since i have no idea about how to initialize it. i've used another lcd modual(text mode) before, it use led (with a little box) as the backlight, but the sed1520 use a white foil as the backlight which i cannot light it up by directly pass the 4.2v to it. what other things i need to do with it? |

seems no driver update for over a year, continue waiting on sed 1520 with external clock driver... |
