Hi folks.Don't know if anyone remembers that I had the plan to use negative backlite character LCD's instead of the (for home building) 7-segment displays.I have the PHCC interface running for quite some time now and I got 10 of them 8*2 LCD's. With the PHCC I can fire up 8 of them.PHCC is an interface "under construction" so I had to take on the software part myself. Using C++ I now manage to get the right data out of FS (NAV,COM,XPDR,ADF,APalt) and it's now just a matter of time untill I got them showed on the LCD's. I got the code working for 1 LCD. The base is there, it only needs some code to be linked & sorted.To give you guys an idea ..The PHCC equipment cost me

so, these character LCDs will basically emulate the real Airbus style displays instead of the boeing-style LCD displys, right?This is a big boon to those Airheads...i mean airbus heads...;-)Awesome discovery. Hopefully, it will help someone achieve the much realism and satisfaction we all hope to achieve someday.

Hi,I don't know the difference between an airbus lcd and a boeing lcd but for sure their ain't much 7-segments being used in real aviation.The list of advantages using character lcd's instead is quite long.Simple wiring is 1. No PCB (got one already) required is 2. LCD is used in real aviation is 3. Price is similar is 4. No italic font is 5. You could show other characters than just numbers is 6. 2*8 sized LCD is ideal for radios is 7. They don't need tinted glass over them is 8. A LOT less wires is 9. A lot less outputs used from your interface is 10. And the 11th advantage .. check out the images below (notice how the decimal point shows ...)http://users.skynet.be/porreke/lcd2.jpghttp://home.planet.nl/~nwkaan/images/Overh...tal/normal2.JPGFinaly #12 advantage is that you can put in a 4*40 LCD and show lots and lots of data you would normaly not have displayed in your sim on there (even make a toggle button to show different data on there)PS: I almost forgot to add that you can upload your own font to the LCD to get the numbers like this:http://users.skynet.be/porreke/newfont.jpgI've changed the 4 and 7. Their "legs" are longer now.

All I meant was the MCP. The Airbus guys don't seem to use conventional 7-Segment LCD type displays, but most builders end up making something that works. I believe there is also a matter of the mode selection of the MCP is reflected in the text *ALTITUDE* when altitude hold mode is engaged or something to that effect. This would open up a whole new can of worms.

To give you folks an idea here's a movie:http://users.skynet.be/plipke/lowspeedlcd.avihttp://users.skynet.be/plipke/highspeedlcd.aviThe first one had bad update speed on the LCD. I noticed that the reason for it was that FS was in foreground and the LCD-PHCC software in background. I changed that around in the second movie and asigned some joystick buttons in FSUIPC so that I could change the freq with having FS in background.Looks a whole lot better now. I'll still try to even further increase speed (never have enough speed on radio's).Comments ?

Beautiful work are there any single line LCD

Single line for radio's ? I thought the 2 lines for radios were perfect ? Unless you building a cessna where they are side by side.Either way, I think 8*2 is the smallest negative backlit I have found with a controller PCB attached. I plan on "hiding" the parts I don't need with a mask.

Well Airbus and Boeing use single line that is what I meant! Probably for other types double lines is great.Roberto

>Hi,>>>http://users.skynet.be/porreke/lcd2.jpg>>http://home.planet.nl/~nwkaan/images/Overh...tal/normal2.JPGGot you!! My lawyer will show up in Belgium next week to sue you for using my picture without my permission ! ;-)But no kidding: With pictures you can mislead people quite easily. In reality the decimal point is a litle bit stronger and I can easily make it even more bright by reducing the resistor value. So what's the problem? Besides that I do not really need the decimal point. With a fixed display of 5 digits you just "know" what it means.I also have lcd displays in my cockpit but I prefer the 7-segment displays; especially because they can be controlled with IOcards quite easily (like blanking out, removing leading zeroes, showing special characters, changing from blank to - and or to + ...). My 2 cents,Groeten uit Nederland,Nicowww.nicokaan.nl

Don't mean to offend you or your project in any way. It was my own experiance at home that freq's look more like 12280 than 122.80 on segmented displays. And I personaly don't like that.I can understand if you have IOcards you prefer having those segmented ones but for the same price you can have LCDs and use all those tons of outputs for separate leds. And I too can show anything I want on my LCDs and edit as much as I want.Either way, no offence ! I love what you are doing and it all looks amazing and is a good example for lots of folks out there. I didn't mean "folks, look what to do and what not to do" .. just show the differences between LCD and segments.
