Library Documentation

---

MD_MAX72xx_DaftPunk
Uses the library to display a Daft Punk LED Helmet animation.
The display can be set to change animation through a switch or just cycle through all the animations.

---

MD_MAX72xx_Dynamic_HW
Use the library to display text on the display while cycling through the library supported hardware types. It prints out the module type - the one that is legible on the display is the type of hardware being used.

This is an easy way to determine what type of hardware is being used as an alternative to the HW_Mapper sketch. Recommended that at least three modules are used.

---

MD_MAX72xx_Eyes
Uses the graphics functions to animate a pair of eyes on two matrix modules. Eyes are coordinated to work together and are created to fill all available modules.

---

MD_MAX72xx_Hourglass
Uses the graphics functions to animate an hourglass on two matrix modules. The matrices are placed diagonally touching at one point.

---

MD_MAX72xx_HW_Mapper
Test software to map display hardware rows and columns. Uses a generic SPI interface and only one MAX72xx/8x8 LED module is required. This code does not use any libraries as the code is used to directly map the display orientation.

The user needs to observe the display and relate it to the MAX7219 hardware being exercised through instructions and output on the serial monitor. The outcome is a recommendation used to set the hardware type for the library.

---

MD_MAX72XX_Message_ESP32
Use the MD_MAX72XX library to scroll text on the display received through the ESP32 WiFi interface. Text is sent from a web page served by the application and displayed as a scrolling message on the display. The IP address for the ESP32 is displayed on the scrolling display after startup initialization and WiFi is connected.

---

MD_MAX72xx_Message_SD
Demonstrates the use of the callback function to control what is scrolled on the display. Text to be displayed is stored on a SD card file. Each line from the text file is scrolled continuously on the display and run off before the next one is shown. At end of file the display loops back to the first line. The speed for the display is controlled by a pot on an analog input.

---

MD_MAX72xx_Message_Serial
Demonstrates the use of the callback function to control what is scrolled on the display text. Text typed on the serial monitor and will display as a scrolling message on the display. The speed for the display is controlled by a pot on an analog input.

---

MD_MAX72xx_Pacman Use the MD_MAX72XX library to display a Pacman animation. Because we can!

---

MD_MAX72xx_PrintText Demonstrates the use of the library to print text. Text typed on the serial monitor and this will display as a message on the display.

---

MD_MAX72xx_PrintText_ML
Demonstrates the use of the library to print text on multiple lines by using separate matrix displays (no zones). The DAT and CLK lines are shared with one LD/CS per string of matrix devices. The user can enter text on the serial monitor and this will display as a message on the display.

---

MD_MAX72xx_PushWheel Use library to create an mechanical pushwheel type display. When numbers change they are scrolled up or down as if on a cylinder.

---

MD_MAX72xx_RobotEyes
Uses a sequence of bitmaps defined as a font to display animations of eyes trying to convey emotion. Eyes are coordinated to work together.

---

MD_MAX72xx_RPS_Game
Simple implementation of the Rock/Paper/Scissors game using switches and LED modules. Play against another player or against the Arduino.

---

MD_MAX72xx_ScrollChart
Implements a scroll chart across the display using random numbers. Display style can be changed from line to bar chart, triggered by a switch.

---

MD_MAX72xx_Shift
Tests the library shift and transform functions.

---

MD_MAX72xx_SimplePong
Use the library to play Pong using just one 8x8 LED matrix. The bat is controlled by 2 switches for left and right movement. Optionally use a pot on analog input to set the speed.

---

MD_MAX72xx_SimpleSlots
Implements a slot machine type display with scrolling symbols and simple sound effects. Control is through a digital switch and sound uses the Arduino tone() facility.

---

MD_MAX72xx_Test
The main testing sketch for the library. This also demonstrates almost all the functions of the library.

---

MD_MAX72xx_Zones
Implements the 'zones' concept from MD_Parola without the Parola library. The display is divided into separate sub-displays and managed independently.
