hi, can any professional working with 89C52, help me to get the code to interface the Dot Matrix (5x7). Please help matter is urgent. Regards ajay
help me to get the code to interface the Dot Matrix (5x7). nope, printer interfaces are manufacturer specific. Without manufacturer and model, nobody can Erik
"the Dot Matrix (5x7)." What dot matrix - LEDs? LCD? Printer? Mechanical indicator board? etc? etc? What is your specific difficulty?
sir, iam a new hobbiest & i don't know how to operate the dot matrix printer and led moving display.so,u please send me mail giving hints how to design a code for that
hello. Did you have a program to project Matrix (5x7) on 89c2051 or 89c51 ??

Hi Ajay, If the dot matrix is a printer, are you trying to drive it or interpret the signals driving it? Either way (as already requested) please can you clarify what the dot matrix is that you are trying to interface to.... If it is a print head that you are trying to collect the signals from, this is something that I have done for about 10 yrs and will try to offer you some advice on how I went about it, but without knowing your goal(s) I can only advise you on what was important for my projects. Mark.
in this therad :"help me to get the code to interface the Dot Matrix (5x7). nope, printer interfaces are manufacturer specific. Without manufacturer and model, nobody can.. Then you post Did you have a program to project Matrix (5x7) as a global question Sheer brilliance Erik

I think you want to drive a dot LED-matrix-display. Try http://www.maxim-ic.com search MAX6952 or MAX6953 a 4-Wire Interfaced, 2.7V to 5.5V, 4-Digit 5*7 Matrix LED Display Driver. The IC is a little expensive, an other solution is combined Hard/Software: You need some SIPO IC's (Serial input parallel output) for Example 74HC4094. Similar solutions could be found in schematics of "rolling advertisement Display's" I have developed a 6-Digit-didital-clock with this kind of driving. I have a schematic and an assembler-file. If it is of any help for you, i will post it. Hope it is posible to attach a PDF-File to this forum. Best regards
