    Multiple LCD's for pedestal radios

    Hello everyone.

    it's been a long time since i was active on forums regarding FS and homebuilt hardware.
    Nice to see all the devellopments over the years.
    Kudos to Jim for his link2fs.
    This finaly gives me something i never thought was possible in a simple way.
    Getting info from FS and sending it to my hardware.

    My idea is just to send the active and standby frequencies on com1, nav1, nav2, adf1, adf2, and also the xpdr to LCD's via arduino.
    I will be using 6 LCD's on one Arduino Mega. I plan on using LCDs with an I2C backpack.

    But this i my first arduino project!!!!
    To give you som idea of my setup, i 'll include some pictures.
    All the hardware is using some USB gamepad's and lots of Leo Bodnar cards so far.

    Hopefully some people can send me some nice links to code that might be suitible to my project.

    Kind regards to all.

    This should be pretty easy. Make sure you get the I2C piggyback boards that have solder pads for setting the I2C address!! The code is SUPER simple for this. Are you going to use encoders or pushbuttons to adjust frequencies?

    Hi Buddym,

    Good tip on the adressing of the I2c cards.
    There are some webshops in the Netherlands selling different versions of the cards/piggybacks.
    The encoders are now on the bodnar cards.
    I think i will keep them there for now, since it is so easy to assign functions to them in FSUIPC or LINDA.
    There is a lot of info on this forum, with code to get good performance and accurracy with encoders on Arduino.

    I like to fly different aircraft, MD-11, F-70 and B737, fo the setup needs to be somewhat flexible.

    Depending on my luck with Arduino, i might add more functions to the Arduino.

    I will experiment with some code on just one LCD.
    I hope to get my first data from FS on the LCD this evening.

    Cheers

    Re: Multiple LCD's for pedestal radios

    I was wondering, have you looked at any of the LED or LCD modules that you can use SPI on instead of I2C? I have used the LM1640 LED modules and they are great. I have some LCD modules on the way that should be the same to implement with the Arduino. The individual digits are much larger, single line, but normally only numeric characters.
    Here's a link to one of the modules have on order:

    Should be really cool.

    Hi Buddy,

    Those are some pretty nice displays in your link.

    The LM1640 do not really suit my need in the pedestal.

    Personaly i like the white blue lcds, I'ts like in the MD11
    I chose the I2C because thats what i came across when searsching the web for multiple displays on arduino.

    Also really happy to report that i got the code for my COM1 figured out!!
    Took be about an hour for nice results. Thanks to a great example from Jim.
    Now waiting for more displays and to see if i can get the adressing sorted.
