What's the purpose of this project?
In this section, we are going to launch the BU27006MUCZ sensor using ARM microcontroller, STM32F series. In order to use more conveniently and optimally in this project, we use two ready modules GB615EN and GebraBit STM32F303. These two modules contain the minimum necessary elements of the BU27006MUCZ sensor and the STM32F microcontroller, which are provided by the GebraBit team to facilitate the work.
What are we going to learn in this tutorial?
In this tutorial, in addition to setting up and using the BU27006MUCZ sensor, you will get to know all the BU27006MUCZ sensor registers, how to set the various parts of the STM32 microcontroller to set up this sensor using the I2C protocol, how to use the GB615EN module specific library and driver file. You will also learn how to declare functions and finally receive sensor data in the Keil compiler.
What do we need to start this project?
As you probably know, we need some hardware and software to do this project. The titles of these hardware and software are provided to you in the table below and you can prepare/download by clicking on each of them and get ready to start.

First as shown in the image below, we connect the GebraBit BU27006MUCZ module to the GebraBit STM32F303 module as follows:
Note: Considering that the PA14 pin of the GebraBit STM32F303 microcontroller module is used to program the microcontroller, the I2C setting on the PA14 and PA15 pins is not possible in this version, so the GebraBit BU27006MUCZ module cannot be placed as a pin to pin on the GebraBit STM32F303 microcontroller module.
Finally, we will see the values of RED, Blue, Green, IR and Flicker in Real Time in the “Watch1” window of the Keil compiler in the “Debug Session” mode.
STM32CubeMX settings
In the following, we review the settings related to each of the “I2C”, “RCC”, “Debug”, and “Clock” sections in the STM32F303 microcontroller to develop the GebraBit BU27006MUCZ module.
RCC settings
Due to the presence of “8Mhz” crystal in the GebraBit STM32F303 module, we select the “external clock” in the “RCC” section:
Debug & Programming settings
Regarding the access to “SWCLK” and “SWDIO” pins in the GebraBit STM32F303 module, to reduce the number of pins during “Debug & Programming”, in the “SYS” block, we select the “Serial Wire” option in the “Debug” section:
I2C settings
To communicate with the GebraBit STM32F303 module through I2C, select the Standard Mode with a speed of 100khz and select PB8 and PB9 pins as SCL and SDA:
According to the sensor data sheet, the settings of the I2C parameters in the “Parameter Settings” section will be set as shown in the above image.
Clock settings
The “clock” settings for each part of the STM32F303 microcontroller in this code, are as follows:
Project Manager settings
“Project Manager” settings are as follows, here we have used “MDK-ARM” version “5.32” compiler:
After completing all the above settings, we can develop our code easily just by one click on “GENERATE CODE” and adding the BU27006MUCZ library and driver (provided by GebraBit).
You can download the “STM32Cube MX”, “library”, “driver” and KEIL project at the end of this tutorial.
BU27006MUCZ library and driver
In addition to the modular design of various sensors and ICs, GebraBit tries to provide variety of structured and hardware-independent libraries in C language for the ease of users in setting up and developing software.
For this purpose, after preparing each GebraBit module, the users can refer to the “tutorial” section of the desired module and download the dedicated library, which contains the “ .h” and “ .c” file (Header and Source) and a sample training program under “GebraBit STM32F303”, “GebraBit ATMEGA32A” or “Arduino” development boards.
All the defined functions and structures in the library are commented in full detail and all the received parameters in the arguments of the functions and their return values, are briefly explained. Since the libraries are hardware independed, the user can easily add the library in any of their favorite compilers and develop it by desired microcontroller and development board.
GebraBit_BU27006MUCZ.h header file
In this file, based on the datasheet of the sensor or IC, all address registers, the values of each register are defined in the form of “Enumeration”. Also, the casing of the BU27006MUCZ sensor and the configurations related to each of the BU27006MUCZ sensor internal blocks are defined in the form of a “STRUCT” with the name GebraBit_BU27006MUCZ Finally, in the Debug Session environment, all the configurations related to each block can be seen in real time.

GebraBit_BU27006MUCZ.c source file
In this file, which is written in C language, all the functions are commented in full detail, and all the parameters received in the arguments of the functions and their return values are clearly explained so we confine to these explanations and invite users to check this file directly for more information.
Sample program in Keil
After making the Keil project by STM32CubeMX and adding the “GebraBit_BU27006MUCZ.c” library provided by GebraBit, we will examine the “main .c” file of the sample tutorial and view the output of the GebraBit_BU27006MUCZ module in the “watch” part in the Keil compiler “Debugging” environment.
Description of “main.c” file
Enums and functions required by GebraBit BU27006MUCZ module have been added to the structures. In the next part, a variable named BU27006MUCZ_Module of the GebraBit_BU27006MUCZ structure type (this structure is in the GebraBit_BU27006MUCZ header and is explained in the GebraBit_BU27006MUCZ library description section) is defined for the configuration of the GebraBit BU27006MUCZ module:
/* Private typedef -----------------------------------------------------------*/
/* USER CODE BEGIN PTD */
GebraBit_BU27006MUCZ BU27006MUCZ_Module;
/* USER CODE END PTD */
In the next part of the written code, using the GB_BU27006MUCZ_initialize (&BU27006MUCZ_Module) and GB_BU27006MUCZ_Configuration (&BU27006MUCZ_Module) functions, we set the GebraBit BU27006MUCZ module and finally, in the while part of the program, the data is read from the sensor and the RED, BLUE, GREEN, IR and Flicker values are continuously received:
1. /* USER CODE BEGIN 2 */
2. GB_BU27006MUCZ_initialize(&BU27006MUCZ_Module);
3. GB_BU27006MUCZ_Configuration(&BU27006MUCZ_Module);
4. /* USER CODE END 2 */

Program output
After generating the Keil project using STM32CubeMX and adding the library, we connect the STLINK V2 programmer to the GebraBit STM32F303 using the STLINKV2 adapter:
STLINKV2 adapter
By connecting the STLINK V2 programmer to the GebraBit STM32F303, there is no need to apply power to the GebraBit STM32F303 and GebraBit BU2700MUCZ modules, because they receive their supply voltage directly from the STLINK V2 programmer.
Finally, enter the “Debug” mode and by adding the “BU2700MUCZ_Module” to the “watch” window and running the program, we can see the changes in the RED, BLUE, GREEN, IR and Flicker values of the GebraBit BU2700MUCZ module:

In the following, you can download the “GebraBit BU2700MUCZ module setup project” using the GebraBit STM32F303 module in the Keil environment, the “STM32CubeMX file”, the schematic of the modules and the “BU2700MUCZ datasheet”.
