Hello,
I am NEW in this forum ,and I am NEW in this topic.
I have got old AKAI drum machine with 240x64 display nanox nfm 243(not integrated with drum machine PCB but on 10 pins ribbon) and this display use sanyo LC7981 controller ( on the drum machine pcb ).
I would like to start with few Question:
1.is it posible to make converter which one will be show information from this nanox display on PC screen?
2.if YES, is it posible to use USB or any other data transfer format?

Thank YOU,

Marek

1) yes it is possible...
providing you have the time and patience to 'figure out the details'..
hopefully you have good 'low level' documentation or a good understanding of 'how it works'.

2) yes, easiest to use a ttl<>usb module($5).easy as NO PIC driver required for USB stuff,cheap and saves a LOT of R&D time.

Hello,
AND big Thank You for YOUR quick reply!!!

YES I am really want to do it:))

I have got this information from service manual for that drum machine:
This is pinout from display connector (where this display is plug).

1pin VO
2pin VEE
3pin GND
4pin VCC
5pin NC
6pin CP
7pin LOAD
8pin DF
9pin FLM
10pin LD1

I would like do wiring to parallel port.(or USB?)
How will be looks like wiring.

IF is possible, I want keep drum machine display on the same place
but use this converter to PC as external option (probably with port on the back d.machine) when I am
recording in studio just plug drum machine(data from display) to PC.

If someone could help me with my first project,
YES, I am learning all this tricks which I have got from helpful links
but I want move forward, as well everyday.

Which parts (board, module) I need to buy for the "GOOD" start. (maybe easiest solution for beginning)
and from which software (if is possible free) I have to start .

Hi,

Frankly, I think you are in the wrong place (forum)! This is a forum for users
of the CCS 'C' compiler that have compiler related questions. While we
occasionally stray into hardware areas, it's only in connection to a related
compiler question.

The CCS 'C' compiler is not free!

Moreover, your project is quite involved, and broad. It is not a good
beginners project. You should pick something else (easier!) if you really
want to learn embedded programming using the CCS compiler.

Cheers,

John
