Color Control Light

1. Summary

We used to have a reference design about color-control-light which is RD-0098-0401, but it's deprecated now. All the documents about this reference design can't be found on Silicon Labs' official website.

This example is a Zigbee color-control-light example based on Thunder Board Sense 2. It demonstrates controlling RGB color using Zigbee.

Below is the hardware layout of Thunder Board Sense 2:

2. Gecko SDK version

Gecko SDK Suite 2.7.

3. Hardware Required

4. Connections Required

Form a Zigbee network on the light, and then join the switch into the network.

5. Setup

5.1. Setup the Light Project

  1. Create a ZigbeeMinimal project, name it with "Z3ColorLight" and select the "BRD4166A" (the board type for Thunder Board Sense 2) as the board.

  2. In "Zigbee Stack" tab, set the device type to "Coordinator or Router".

  3. In "ZCL Clusters" tab, select endpoint 1, then in "Zigbee device type" field, change it to HA devices-->HA Color Dimmable Light.

  4. In cluster "Color Control", enable the following attributes:

    • remaining time
    • color mode, default value set to 1.

  5. Set the default value, so that the RGB LEDs will be turned on by default.

    • In cluster On/Off, set default value of on/off attribute to 0x01.
    • In cluster Level Control, set default value of current level attribute to 0xC8.

  6. Enable the following plugins:

    • On/Off Server Cluster
    • Level Control Server Cluster
    • Color Control Cluster Server
    • Buld PWM Driver
    • Led Rgb Pwm
    • Network Creator
    • Network Creator Security
    • Source Route Library
    • Identify Cluster
    • Find and Bind Target

  7. In plugin "Serial", in the properties, select USART0, change the Flow control mode to No flow control, then save.

  8. In plugin "Bulb PWN Driver", select BULBPWM_COLOR, check the Enable, and set CC0, CC1, CC2 to true.


    Then select **TIMER0**, disable the timer channel **CC0**, **CC1**, **CC2** as TIMER0 will not be used in this example.

    Select **TIMER1**, configure the pins for **CC0**, **CC1**, **CC2** to **PD11**, **PD12**, **PD13** respectively.

  9. In "Callbacks" tab, enable the following callbacks:

    • emberAfMainInitCallback
    • emberAfStackStatusCallback
    • emberAfPluginNetworkSteeringCompleteCallback
    • emberAfHalButtonIsrCallback

  10. Add two custom event:

    • Event buttonEventControl and its handler buttonEventHandler
    • Event closeNetworkEventControl and its handler closeNetworkEventHandler

  11. Save and generate the project.

  12. We need to modify two source files of the SDK because the the corresponding function is not supported on Thunder Board Sense 2. As this source files are linked into the SDK, there will be a pop-up warning windows like below. If you see it, please always select "Make a Copy".


    A. Modify source file `bulb-pwm-driver/EFR32/bulb-pwm-driver-efr32.c`: 
    026		//#define BULB_PWM_USING_TIMER0 Comment this line as TIMER0 is used by the stack
027
028		#define BULB_PWM_WHITE_TIMER      BSP_BULBPWM_TIMER
029		#define BULB_PWM_WHITE_CHANNEL    0
030		#define BULB_PWM_LOWTEMP_TIMER    BSP_BULBPWM_TIMER
031		#define BULB_PWM_LOWTEMP_CHANNEL  1
032		#define BULB_PWM_STATUS_TIMER     BSP_BULBPWM_TIMER
033		#define BULB_PWM_STATUS_CHANNEL   2

    B. Modify source file led-rgb-pwm/led-rgb-pwm.c:

    224		static void driveWRGB(uint16_t white, uint16_t red, uint16_t green, uint16_t blue)
225		{
226		  //halBulbPwmDriverSetPwmLevel(white, BULB_PWM_WHITE); -- comment this line
227		  halBulbPwmDriverSetPwmLevel(red, BULB_PWM_RED);
228		  halBulbPwmDriverSetPwmLevel(green, BULB_PWM_GREEN);
229		  halBulbPwmDriverSetPwmLevel(blue, BULB_PWM_BLUE);
230		}



630		/** @brief Called during blinking behavior telling the bulb implementation to turn the bulb on.
631		 *
632		 * @appusage Should be implemented by an application layer configuration
633		 * plugin.
634		 *
635		 */
636		void halBulbPwmDriverBlinkOnCallback(void)
637		{
638		  //halBulbPwmDriverSetPwmLevel(halBulbPwmDriverTicksPerPeriod(), BULB_PWM_WHITE); -- comment this line
639		  halBulbPwmDriverSetPwmLevel(halBulbPwmDriverTicksPerPeriod(), BULB_PWM_RED);
640		  halBulbPwmDriverSetPwmLevel(halBulbPwmDriverTicksPerPeriod(), BULB_PWM_GREEN);
641		  halBulbPwmDriverSetPwmLevel(halBulbPwmDriverTicksPerPeriod(), BULB_PWM_BLUE);
642		}
643
644		/** @brief Called during blinking behavior telling the bulb implementation to turn the bulb off.
645		 *
646		 * @appusage Should be implemented by an application layer configuration
647		 * plugin.
648		 *
649		 */
650		void halBulbPwmDriverBlinkOffCallback(void)
651		{
652		  //halBulbPwmDriverSetPwmLevel(OFF_TICKS, BULB_PWM_WHITE); -- comment this line
653		  halBulbPwmDriverSetPwmLevel(OFF_TICKS, BULB_PWM_RED);
654		  halBulbPwmDriverSetPwmLevel(OFF_TICKS, BULB_PWM_GREEN);
655		  halBulbPwmDriverSetPwmLevel(OFF_TICKS, BULB_PWM_BLUE);
656		}

  13. Implement the callback file Z3ColorLight_callbacks.c. Refer to the file in the project.

  14. Save and build.

5.2. Setup the Switch Project

  1. Create a ZigbeeMinimal project, name it with "Z3ColorSwitch" and select the "BRD4166A" (the board type for Thunder Board Sense 2) as the board.
  2. In "ZCL Clusters" tab, select endpoint 1, then in "Zigbee device type" field, change it to HA devices-->HA Color Dimmable Switch.
  3. Enable the following plugins:
    • Find and Bind Initiator
  4. Enable the following callbacks:
    • emberAfStackStatusCallback
    • emberAfPluginNetworkSteeringCompleteCallback
    • emberAfHalButtonIsrCallback
    • emberAfPluginFindAndBindInitiatorCompleteCallback
  5. Add a custom event buttonEventControl and its handler buttonEventHandler.
  6. Save, generate.
  7. Implement the callbacks in the file Z3ColorSwitch_callbacks.c and build. Refer to the file in the exported project.
  8. Save and build.

6. How It Works

  1. Flash the light and switch program into the two boards.
  2. On the console of the Light, press button0 to create a network. When its done, the LED (The LED in the middle of the board, not the RGB LED) will turn orange.
  3. On the switch, press button0 to start joining. This must be done when the LED of the light is orange. If it's red other than orange, press button1 of the light and then press button0 of the switch. If the switch joined successfully, the LED of the switch will turn orange.
  4. Press button1 of the switch to change the color.

7. .sls Projects Used

8. How to Port to Another Part

This example can be used on any parts. Below are the steps of porting it to other part:

  • Import the .sls file into Simplicity Studio
  • Open the .isc file of each project, turn to "General" tab, hit button "Edit Architecture", then select the board and part.
