The Shield communicates with a master board via the I2C protocol as a slave. Either an Arduino Uno R3 or the XMC1100 Boot Kit from Infineon can be used as the master. On board the RGB LED Shield is an XMC1202 microcontroller, featuring a dimming control peripheral for LED lighting applications, known as the Brightness and Colour Control Unit (BCCU). It contains 3 independent dimming engines and 9 independent Pulse Density Modulated (PDM) channels. 1 dimming engine and 6 channels are used in this shield. There are 10 basic sets of I2C commands to control the shield from the master board, and so control the connected LED Lamp with various lighting effects. There are 22 user configurable parameters and the freedom to connect different LED Lamps. The RGB LED Lighting Shield can be easily connected to any Arduino board or the XMC1100 boot Kit via headers and DMX512 control is enabled as a mounting option using an interface chip. Figure 1 RGB LED Shield photo 1.1 Key Features The RGB LED Shield has the following features: 2  Behaves as an I C slave. − An Arduino Uno R3, XMC1100 Boot Kit, or similar board connected to the shield can communicate via the SDA and SCL pins as the master.  Drives and dims up to 3 LED strings with constant current.  Able to change the colour of a connected LED lamp(if the strings are of different colours; for example red, green, blue).  High speed flicker-free modulation dimming on each string with Pulse-Density Modulation (PDM).  Very high power density due to high switching frequency, leading to a small area. Board Manual 7 V1.0, 2014-11 RGB LED Lighting Shield with XMC1202 for Arduino Introduction      Up to 48VDC input. − The RGB LED Shield is a DC-DC buck LED driver so the input voltage must be higher than the forward voltage of the LED strings. Configurable current amplitude. Up to 700mA average current on each string. Configurable current ripple. I²C interface with configurable 10-bit slave address (with a default value of 0x15E) to increases the range of devices that can be connected to the bus line.

Free DAVE™ IDP and DAVE Apps (code library) open to 3rd party tools and the wide ARM® ecosystem. 1.3 Getting started The RGB LED Shield uses high frequency peak-current control with fixed off-times to generate DC LED currents. Although this is highly efficient, low cost, and is suitable for high-speed dimming, it results in the output current being dependent on the input and output voltage ratio. The output current can be adjusted by configuring the peak-current reference and off-time parameters. A virgin RGB LED Shield is pre-configured with safe peak-current reference and off-time parameters. With the safe parameters, the LED current will not be ‘too high’ at high input voltages. The safe parameter values have been tested with LED loads that have a forward voltage of 6V at input voltages up to 48V. At this input, the pre-configured average LED current is measured up to 300mA. Note: LED strings that have a forward voltage lower than 6V and current capability lower than 300mA should not be connected without re-configuring the shield first. The safe parameters will however result in a discontinuous current with most LED strings and input voltages. For low-ripple continuous current, the off-time and peak-current reference parameters must be configured by the user once the LED lamp and input voltages have been selected. Generally, the current in any of the strings should never exceed 1A, the peak-current reference parameters should be kept below 0x80, and off-time parameters should be kept above 0x10. Attention: Improper configuration may result in permanent damage.
