i trying to build up a program that send a bitmap to the lan printer directly to the ip address
i'm looking for code (c#,c++) that can make the job like the printer driver do.
something that can "talk" with the printer and send directions and data.
i have a service that sends thousands printings to several printers (lan & wan) and it's take long time until the page go out,
getting the driver from the print server, init the printer, spooling (in the server that spool the printer hardware...)
i realised that if i install simple driver(PCL5 etc..) for advanced printer it's work faster!
where i can find piece of code that send to the printer ip some instructions for start ?
I have got old drum machine with 240x64 LCD screen,
What I want to do is send signal from ribbon LCD to PC and encode to see all information on PC screen(240x64 is very tired to looks for 4-8 hours when I work in the studio)
This ribbon coming from drum machine mother board after lc7981
How to connect to PC ?(USB board or pallalel)
ON that ribbon I have got this data:
pin on LC7981 and data:
5.MB LC drive signal
10.FLM Frame signal
11.CL1 Display data latch signal
46.CL2 Display data shift clock signal
47.D1 Display data Upper SCreen
do I need anithing more?
Any LCD simulator in PC or Mac ?
Or I need to read my program ?
Thank You for your answer ))
It is no easy to find musician on this platform
This is old sampler Akai Mpc 3000
I am looking for some info how rebuild or reverse existing LCD to VGA board (very fussy works only with few monitors because 31.5 kHz/ 59hz )or build new one.
I have got schematic and good pictures (but use peel18cv8 and 22v10 with security bit on
It means not POsIBILE to copy).
I am not sure about SDK for Akai?
If some one can help me
I've seen interfaces to do from a PC to an LCD but I haven't seen anyone go from from an LCD to a PC. There are a number of practical problems you would have to overcome.
Rather than trying to do something after the LCD controller chip, you might be better off picking off the the signal between the micro-controller and the LCD controller chip. The interface will be simpler. Between the central micro and the LCD controller the interface would likely be 7 to 12 pins depending on if they implemented half-word or full-word interfacing. If you can identify the data pins (Usually D0 thru D3 or D7) and the clock pin, you could probably program you own micro-controller to emulate the LCD control chip (and hence the whole display). Starting with the pin-out on the LCD control chip would be a good place to begin. (Actually, the manual on that chip would probably be required to have half a shot at making this work) However, you'll need to break out a logic analyzer and you'll probably need to write your own emulator using something like an Atmel AVR micro. Those chips would work well because they have a USART that you can connect back to a PC to pass in the display data as a serial data stream. Then you would just need to craft something on the PC to receive that data stream and display it in a 'virtual lcd' on screen.
Hello, Guys. Again , thank You for answers.
How I can see it is no point to works with LC7981(LCD controller).
For beginner like me, probably I need some more advice:
-which avr xmega interface (board) for controlling LCD (virtual in PC )
With USB and parallel port can I use for this project(links or full item name will be
-which connectors have to read (obtain) from MCU.
I know data bus(D0-D7) , CS/, R/W and which more? To
Connect to xmega interface or o'scope?
