FDS-125 display with Arduino (2)

original article

   In previous article I present you how can conect an FDS-125 display to Arduino and how mase a simple, but "static" clock style

   For made an "dynamic" clock, I use some schematic

  I write in exitting sketch to display name of day in week in 2 language (romanian who is my navitve language and in english). It easy to change in your navive language by writting name of days in one line:

  Is very important to have in same subdyrectory of sketch font75.h file like in this picture:

  So, by uploading FDS125_clock1b.ino sketch, you cand see on display new info, beside date:

   In Arduino clock on FDS-125 display (2) movie you can see on FDS-125 display all info:

   After that, I put an AM2302 (DHT22) sensor for humidity and temperature, like in next picture:

   Newest skertch is FDS125_clock_RTC1c.ino and on display you can see new situations:

like in Arduino clock on FDS-125 display (3) movie:

   Because, DHT sensor is too slow when is reading, I made some changes to see temperature and humidity in same times, also I chege font75.h file to display degree symbol instead ': 

  New sketch is FDS125_clock_RTC1c1.ino and this new style can be see it on Arduino clock on FDS-125 display (4)

FDS-125 display with Arduino

original article

   This display was received from Janos Baricz, vintage things passionate. On webworld, we find just some info and tests with FDS-132 display who is bigger than FDS-125.

   So, you can see info about "big brother" at:

- circuitsonline.net - Baco Led Matrix

- FDS132-textdriver library

- arduinoforum.nl: Lichtkrant Surtronic FDS-132

- arduinows.blogspot.com: FDS132 ledmatrixbord

   FDS-125 display has 2 big rows, each with 7 rows and 60 columns (12 matrix 5x7 leds) controlled by Lattice MACH21 microcontroller.

   For control by Arduino must extract Lattice MAC21 microntroller and put few wires like in this pictures from arduinows.blogspot.com:

   Janos made hardware part for this display:

and in this case, situation is:
- green wire is A from FDS-125 display, must connect to D5 pin at Arduino board

- pink wire is B from FDS-125 display, must connect to D6 pin at Arduino board

- white wire is C from FDS-125 display, must connect to D7 pin at Arduino board

- yellow wire is STROBE from FDS-125 display, must connect to D10 pin at Arduino board 

- mauve wire is DATA from FDS-125 display, must connect to D11 pin at Arduino board 

- grey wire is CLOCK from FDS-125 display, must connect to D13 pin at Arduino board 

- blue wire is RESRED from FDS-125 display, must connect to D9 pin at Arduino board 

- black wire is GND from FDS-125 display, must connect to GND pin at Arduino board 

Also, on the back site is power for display (in picture is a red wire connected from power conector at power of display part).

  I redesigned connexion between FDS-125 display and Arduino board:

   After that, I tested some sketches and I "lit" the display

   I put an RTC clock made with DS3231 (works fine with DS1307, also) and adapt an sketch from arduinoforum.nl made for FDS-132. Result is FDS125_clock.ino sketch and test schematic is:

   Whem upload the sketch on display is on top row is data and on bottom row is hour:

   Also, I made Arduino clock on FDS-125 display movie to see how clock is..
