Hi Jack Thank's again for everything you have done to help me. I wasn't lucky about this card. At least the other card (USBouts) works. I'm trying FSLCD (I purchased a paralel port and I'm waiting to receive it). Testing this program, only two offsets work well on my wilco airbus FCU (SPD and HDG. ALT and VS don't change values when turning buttons). SIOC would be better, but I will not buy another card or LCD again without knowing what's wrong. Thank´s again for eveything. Cheers Gabriel

Hi Jack. After reading another of those posts, I could see that LCD contoller was KS0066 and not HD44780. Maybe the issue on that case. Anyway no input data on LCD. It seems to be a compatibility issue. Open Cockpits could have a test program to USBlcd, like "test_outputs.exe" (to USBouts card), just to be sure that USBlcd is ok. They don´t have any LCD to be purchased, and it was important to know were to buy any LCD already tested. They talk about "standard Hd44780". What they mean standard? I can find on Ebay many LCDs w/HD780 controller, but nothing about "standard" (or not).

(sometimes I feel stupid with this kind of mistakes) Here there are some photos Sorry Jack!

I Jack Everything is correct. My diagram and yours are quite the same. Only a little difference on backlight (I have a 100K pot). I was trying do post some images from photobucket, but forum "says" I am not allowed to do that (I don't understand or I'm making any mistake). If you don´t care, I'm sendind them by mail. (I'm trying again)

I think I have a problem with photos http://s965.photobucket.com/user/manuelgnunes/library/

I Jack. The ebay site of LCD is this: http://www.ebay.com/itm/291020239150?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1497.l2649 Soon I'll get some photos of LCD "working". About photos of my wiring, I think it will impossible to identify the connections on photo. Only I can say they are just like Open Cockpits shcema. (I tested then one by one "again").

Hi Jack I did overwritte the original IOClcd.lcd file. I have this file on the same folder as IOClcd.exe and the IOClcd.ini files. The IOClcd.exe finds the file, because I made a test renaming it, and the program says "IOCLCD.LCD: File not Found!!". I deleted the "./", but nothing different because it's only to find the file in a sub-folder. The information of the LCD on EBAY is: "Black 40x2 Character LCD Module Display,w/HD44780 Controller,Bezel,White Backlit". I asked Open Cockpits support about this, because I don't know how to find what is wrong (card or LCD). I wired everythi

Hi Jack, I could understand everything about IOClcd.ini. Device is correct (in my case is 25); USB=No, etc. This is my .ini file: [ Configuration file for IOClcd ] Minimized=No MUSB=No deviceUSB=25 IOCP_host=localhost IOCP_port=8092 IOCP_timeout=4000 refresh=80 CONFIG_FILE=.\IOClcd.lcd The 2x40 seems to be ok, when connecting USBlcd card to PC. It appens as I checked in several LCD reviews (one of the two 20 side quares appears black). Now; executing IOClcd.exe, "something appens". Blacks more 4 lines of the other 20 squares, and nothing else It do not assume the data filled on

I'm completely disappointed with everything about LCD's. The 8x2 LCD never get backlight. With multimeter, I found that LED was "gone". I could see that backlight is required because of the brightness (without it you can hardly see anything) I use a 7 port usb hub, powered by a 5V power supply from 220V. I remembered to test the usb power of this hub with my multimeter, and I found 5,5V. That is to say I feed the USBLcd card with 5.5V. Is there any possibility to know if USBLcd card has any problem? When I connect it (now from a direct USB port), system "recognizes" the card, and IOClc

Hi Jack I made a few more attempts, and now I can see all 40 cells become darker, when turning potenciometer (close to 5V they become bright), but NO characters appears (as I filled on IOClcd_config.exe (IOClcd.lcd). Another question is about IOClcd.ini file. Manual says to use USBCheck.exe and find the device (I found 2048), but IOClcd.exe "says" device 23. What the correct device on ini file? Is it necessary to change the "refresh" value? (the indicated is 80). Cheers Gabriel

Hi Jack. I have wired everything. Looking carefully to all connections, they are right. Turning potenciometer 10K, cells change from black to bright white (close 5V). The problem is that only half (20 from 40 cells) do that (just one 20 cells side). Aflter some time, the bottom of the other 20 cells (about half each cell) comes bright. Turning potenciometer 100K, lights some leds inside back of LCD, and changes brightness of LCD (it seems correct). Do you think there is a power problem? I'm quite confused, because turning potenciometer to less resistence, I have 5V on mu

HI Jack. Now I can undersand all the wiring diagram (with your precious help), I have two LCD,s to be connected. 1- 2x40 characters to EFIS/FCU 1- 2x8 characters to QNH. I have all of the necessary parts, and I´m going to wire everything. Merry Chistmas to you and Family.

Hi Jack, I was making a big mess. The "backlighting" meens only output led power (external to LCD). I don´t need any output, but I would like to control the brightness of my characters through potenciometers (white characters on black background colour). Is that possible?

Hi Jack. It´s quite confused, because I never made any LCD connections before. I am sending (via email), the PDF files I downloaded from Seller. Please give me a suggestion about these connections. About this LCD,s my confusion is what standard an backlighted modules are? I got 10K and 100K potenciometers to use if necessary.

I Jack. It was a little difficult to find this kind of lcd. I found them on Ebay China. Manual information on pin configuration, the two last pins: pin no pin name descripions . . . . . . . . . 15 LED_A Backlight Anode 16 LED_K Backlight Cathode Are this two pins for brightness and contrast, as I think they are?
