Parola_Animation_2Speed
Program to show combination of all animations and manual setup process
for animation with different IN and OUT speeds.

Program to show full catalog of the MD_Parola animations.
Parola_Bluetooth_Control
Bluetooth control of Parola text display. Full featured example
controlling a display through a BT interface to change the display
parameters and text.
Provides control of:
- Displayed message text and justification
- Speed, pause time and inverted
- Display intensity
- Saving parameters to EEPROM
- Display config reset, Arduino hardware reset
A companion Android application written using the MIT Application Inventor (AI2) can be run on an Android device to communicate with the Arduino application. The AI2 application is included and AI2 can be found at http://ai2.appinventor.mit.edu/
Parola_CustomChars
Demonstrate the use of single characters font file replacements.
Parola_Display
For every string defined by in the application iterate through all
combinations of entry and exit effects.
Animation speed can be controlled using a pot on an analog input
Parola_Double_Height_Clock
Display the time in a double height display with a fixed width font.
Time is shown in a user defined seven segment font and there is optional
use of DS1307 module for RTC.
Parola_Double_Height_Scoreboard
Demonstrates using double height display to create a scoreboard.
Parola_Double_Height_Test
Demonstrates one double height display using the library an a single
font file definition created with the MD_MAX72xx font builder. The
upper and lower portions of the display are managed as 2 zones
'stacked' on top of each other.
Each font file has the lower part of a character as ASCII codes 0-127 and the upper part of the character in ASCII code 128-255. Adding 128 to each lower character creates the correct index for the upper character.
Parola_Double_Height_v1
Demonstrates one way to create a double height display using the
library and 2 font files.
Largely based on code shared by arduino.cc forum user Arek00, 26 Sep 2015. Video of running display can be seen at https://www.youtube.com/watch?v=7nPCIMVUo5g
Parola_Double_Height_v1_Russian
Demonstrates one way to create a double height display using the library.
This is code for Double_Height_v1 modified with Russian font by arduino.cc forum user borzov161, 25 May 2017.
Parola_Double_Height_v2
Demonstrates one double height display using the library and a single
font file definition created with the MD_MAX72xx font builder.
Parola_Fonts
Display text using various fonts.
Parola_HelloWorld
Simplest program that does something useful ("Hello World!") using
native library methods. This is more complex than Print_Minimal but
allows the full flexibility of the library.
Parola_Print_Minimal
Simplest program to display something ("Hello!"), uses the Arduino
Print Class extension.
Parola_Print_Test
Uses the Arduino Print Class extension with various output types.
Parola_Scrolling
Demonstrates the use of the scrolling function to display text received
from the serial interface. The user can enter text on the serial monitor
and this will display as a scrolling message on the display.
Speed for the display is controlled by a pot on an analog input. Digital switches used for control of text scroll direction and invert mode.
Parola_Scrolling_ESP8266
Demonstrates receiving and displaying text received from a web interface.
The user can enter text through a web page server by the application
and this will display as a scrolling message on the display. Some display
parameters for the text can also be controlled from the web page.
The IP address for the ESP8266 is displayed on the scrolling display after startup initialization and connection to the WiFi network.
Parola_Scrolling_Menu
Demonstrates the use of the scrolling function to display text received
from the serial interface and shared with a menu to change the
parameters for the scrolling display and save them to EEPROM.
User can enter text on the serial monitor and this will display as a scrolling message on the display. Speed, scroll direction, brightness and invert are controlled from the menu.
The interface for menu control can be either 3 momentary on (tact) switches or a rotary encoder with integrated switch.
Parola_Scrolling_ML
Demonstrates the use of the scrolling function to display text received
from the serial interface on multiple lines of matrix displays. User can
enter text on the serial monitor and this will display as a scrolling
message on the display. The message should be prefixed with the line
number on which it should be displayed.
Speed for the display is controlled by a pot on an analog input. Digital switches used for control of text scroll direction and invert mode.
Parola_Scrolling_Spacing
Demonstrates the use of the scrolling function to display text received
from the serial interface and how to adjust the spacing between the end
of one message at the start of the following one. User can enter text on
the serial monitor and this will display as a scrolling message on the
display.
Speed for the display is controlled by a pot on an analog input. Digital switches used for control of text scroll direction and invert mode.
Parola_Scrolling_Vertical
Demonstrates the use of the scrolling function to display text received
from the serial interface in a vertical display. User can enter text
on the serial monitor and this will display as a scrolling message on
the display.
Speed for the display is controlled by a pot on an analog input. Digital switches used for control of text scroll direction and invert mode.
Parola_Sprites_Library
Demonstrates how to set up and use the user defined sprites for
text animations.
Speed for the display is controlled by a pot on an analog input. Digital switches used for control of text justification and invert mode.
Parola_Sprites_Simple
Demonstrates minimum required for sprite animated text.
Parola_Test
Demonstrates most of the functions of the Parola library.
All animations are be run and tested under user control.
Speed for the display is controlled by a pot on an analog input. Digital switches used for control of Justification, Effect progression, Pause between animations, LED intensity, Display flip, and invert mode.
Parola_TG_Combo
Demonstrates the use of Parola to combine text and graphics in one combined
display.
Parola_TG_Coord
Demonstrates using Parola to display text and graphics in the same zone
at different times (coordinated).
Parola_TG_Zones
Demonstrates using Parola to display text and graphics in different zones
simultaneously.
Parola_UFT-8_Display
Demonstrates how UTF-8 multi-byte characters can be mapped to
Extended ASCII characters that can be displayed with a suitable
font file.
Parola_Zone_Display
For every string defined in the sketch iterate through all
combinations of entry and exit effects in each zone independently.
Requires at least 9 modules for 3 zones.
Animation speed can be controlled using a pot on an analog input.
Parola_Zone_Dynamic
Program to demonstrate using dynamic (changing) zones with the
library. Zones are changed by 2 modules for each iteration and
a simple string is displayed in the zone.
Parola_Zone_Mesg
Display messages in the zones. Wait for each zone to finish displaying
before continuing. Animation speed can be controlled using a pot on
an analog pin.
Parola_Zone_Mirror
Iterate through all combinations of entry and exit effects
in 2 zones - one in normal mode and the second in inverted
mirrored mode.
