Hi Benjamin, > Now here are my lcd4linux.conf and the outputs of "lcd4linux -Fvvq". Please, PLEASE, never NEVER send configs, logfiles etc. as HTML!!!! It took me half an hour to extract the real content! Just to tell you that everything looks fine. There may be several reasons: - a wiring fault (you cannot check your wiring often enough :-) - a timing problem (hard to find) - a level problem - a defect display Does the display work with some other software? Maybe with W*ndows? I had some problems with T6963 displays in the past, they really want a high level of +5V on the interface, where most modern parallel ports work on a 3.3V basis. bye, Michael -- Michael Reinelt Tel: +43 676 3079941 Geisslergasse 4 Fax: +43 316 692343 A-8045 Graz, Austria e-mail: re...@eu... |

Hi Benjamin, > sorry for my terrible HTML-Logfiles. Forget about it. But I've got another point: why are you sending two very similar, but slightly different mails? > I'll check my wirings once again. In the display datasheet I've read that 100 > Ohms resistors in series to the LCD-Interface will protect the parallel port by > wiring faults, but there is nothing said about things like the input impedance > and logic levels (CMOS or TTL). This would be VERY interesting. YOu could easily tfind out the level of your parallel port with a multimeter. > So finally I'll remove the resistors and take one more try. may be worth a try.. > On the other hand I don't understand why lcd4linux detects 1991,55300 MHz by my > Athlon XP 2400+ machine, I think this processor is running at exactly 2,000 GHz... lcd4linux does not detect the processor clock, it uses the one detected by the kernel, taken from /proc/cpuinfo. If you have a look at this file, you will find exactly this 1991,5 MHz there. bye, Michael -- Michael Reinelt Tel: +43 676 3079941 Geisslergasse 4 Fax: +43 316 692343 A-8045 Graz, Austria e-mail: re...@eu... |

Has anyone managed to use a Futaba VFD, M202MD10AA? It is from an IBM SureOne POS machine and has a 8 pin phone-type jack connector. The cable and connector seem to be a one-off for this machine as far as I can tell. I can't find any documentation for the connector other than that it is serial, 9600 baud, 8 data bits, no parity, 2 stop bits. Without knowing which pins are which, it is a bit difficult to try it out. The display has no power connector so must also be powered through the serial connector too. Any suggestions for how to connect this or test the pinouts? thanks, Andrew Chapman ----- Original Message ----- From: "Michael Reinelt" <re...@eu...> To: "Benjamin Eichhorn" <big...@we...> Cc: "lcd4linux-users" <lcd...@li...> Sent: Friday, March 12, 2004 5:26 AM Subject: [lcd4linux] Re: M50530 > Hi Benjamin, > > > I got an 24x8 LCD with an Mitsuibishi M50530 display controller and tried to get > > it to work with lcd4linux. > > > > By starting up the display shows to black rows, one on the upper and one in the > > middle of the screen.

Can you see which chips are on the device? As it's a serial device, the beast must consist of two logical parts: the LCD controller itself (which has for shure a microcontroller interface, and not a serial one), and a microcontroller, which handles the serial protocol. Is there a backlight? If so, it would be easy to find out at least these pins. Maybe this is the power for the rest of the display, too. Do you have access to such a POS machine? Maybe you could find out something about the connctors... If you have to go for the "trial and error" way, a power supply with good current limiting is a must. Otherwise you have this special "smell" quite soon :-) bye, Michael -- Michael Reinelt Tel: +43 676 3079941 Geisslergasse 4 Fax: +43 316 692343 A-8045 Graz, Austria e-mail: re...@eu... |

Michael, The controller is a Phillips P87c52. It also has two OKI 8382532 which I assume are memory chips. Isn't it likely to use +5v as power? Presumably if I identify ground, which shouldn't be too difficult, I could then apply +5V to the other pins to see which seems to be for power. Or would doing this potentially fry my chips? There are specs available for other VFD's in the M202 series, but not for this model, presumably because it was a custom design for IBM. The M202SD08 display uses 5V power but is parallel (see http://mem.tcon.net/users/5010/5491/vfd.htm). IBM uses a standard serial controller to drive the device from the Pc end (the SureOne is a Pc with a Via C3 chip and Windows OS), so I would expect the cable to be similar to a standard RS-232 one. The following seems to be the common layout for an 8 pin serial cable, but this doesn't account for power. The SureOne technical documentation gives pinouts for all the other connectors, including both unpowered and powered serial connectors but omits the VFD display connector. 1) DSR 2) DCD 3) DTR 4) SG 5) RD 6) TD 7) CTS 8) RTS thanks, Andrew ----- Original Message ----- From: "Michael Reinelt" <re...@eu...> To: "Andrew Chapman" <and...@bi...> Cc: "lcd4linux-users" <lcd...@li...> Sent: Friday, March 12, 2004 9:04 AM Subject: Re: [lcd4linux] Futaba VFD with phone jack connector > Hi Andrew, > > > Has anyone managed to use a Futaba VFD, M202MD10AA?

That depends. That's why I have a power supply with current limiting. If the display decides to take 15 Ampere at +5V, and the Power Supply decides to supply 15A at 5V, guess what will happen :-) -- Michael Reinelt Tel: +43 676 3079941 Geisslergasse 4 Fax: +43 316 692343 A-8045 Graz, Austria e-mail: re...@eu... |

Dear Michael, I'm download LCD4Linux v.0.9.11 tar ball, my system do not support X11, and I have configuration with --disable-x option, but it seems still somewhere wrong, can't build makefile. would you like tell me how to solve this problem. I don't need build binary with X11 suport. Best regards, Kevin Liu -- MIS Family Technology, Inc.

Hmmm... AFAIK the optins's called '--without-x'. This would explain why you couldn't even build the makefile (which would be a very strange error). If this does not solve your problem, please send me the output of the configure un. bye, Michael -- Michael Reinelt Tel: +43 676 3079941 Geisslergasse 4 Fax: +43 316 692343 A-8045 Graz, Austria e-mail: re...@eu... |

Hi Kevin Liu, >>>I have configuration with --disable-x option, but it seems still somewhere >>>wrong, can't build makefile. would you like tell me how to solve this Looks like you've found a bug in the configure scripts!

Hi Michael, I think I find the problem, replace AC_MSG_ERROR by AC_MSG_WARN the problem still exist until I chnage default value to 'no' in configure driver select session. That in 'configure', line 5341. I can compile right now, I'm running lcd4linux and modify a lcd4linux.conf, but the process just exit, nothing to do. Does something wrong?? Thanks a lot.

Does something wrong?? How does your lcd4linux.conf look like? try running lcd4linux with the arguments '-Fvvq' and have a look at the debugging output.
