Bar-Light-Control

Arduino Project for controlling LEDs build into my bar using TLC5940 drivers and Touchscreen Interface

• The Bar has 41 beer mugs with each containing 6 RGB-LEDs (controlled by 3 channels). Therefore the colour of each mug can be controlled individually.
• Light-scenes are stored on a SD-Card and are simple textfiles that can be written on a computer.
• A big part of the project is a filebrowser API that is use by the GUI library to graphically choose a Light-scene from the SD-Card.

* In the Main Window the Lights can be controlled, like Fading, Music Control, Brightness and Speed.

## Important Info Project is based on an ATmega2560 MCU (Arduino Mega) and will not run easily on any smaller MCU (Maybe with Resistive Touch screen be cause the touch control driver needs lots of memory). At this stage the project is very specific for my hardware setup therefore won't run easily on different setup. However some parts can be adapted for different projects (e.g. the GUI file explorer).

Getting Started

Hardware Setup

This project need a special hardware setup to work:

1. The display used is a 5" TFT with 480x272 pixels using a SSD1963 controller. Generally any display compatible with the UTFT library can be used --> If a different display resolution is used the ledTFT-Library must be modified to fit the screen size
2. A Capacitive touch panel with a GLS1680 controller. If a resistive touch panel is used (recommended! The GLS1680 touch controller makes lot of problems) you can add e.g. the URTouch library. Again the ledTFT-Library.
3. A SD-Card containing the Folder Light-Scenes is connected to the Arduino via SPI.
4. 8 TLC5940 controllers daisy-chained connected to the Arduino according to the setup found on the library GH-Page.

Software Setup

To make this project work the software has to be adapted to the used hardware:

1. Using a different screen resolution: Most of the ledTFT-Library must be modified to fit the screen size
2. Using a different touch panel the updateDisplay Function must be modified in ledTFT.c to read the coordinates.
3. Add the Folder Light-Scenes to a SD-Card (Formatted in FAT or FAT32 system). Change the SPI-ChipSelect PIN in ledTFT.h for your used CS-Pin
4. Modify the number of used TLC controllers in the tlc_config.h. To use a different LED-setup the code in the LEDControl-Library msut be hugly modified.
