PSOC™ 6 MCU: XENSIV™ 60 GHz radar presence detection

This code example demonstrates Infineon's radar presence detection sensor solution for human presence sensing within a configurable distance using the XENSIV™ BGT60TR13C and BGT60UTR11AIP 60 GHz radar sensors. This solution provides extremely high accuracy in detecting both micro and macro motions, enabling efficient user interaction with devices.

The code example utilizes a special optimization mechanism to demonstrate the switching between different radar device configurations on the fly. Depending on the application use case, you can switch between two or more radar configurations. For example, you can switch from a radar device configured for presence detection to gesture control based on certain conditions within the user application (e.g., the range bin information of the detected target).

The code example demonstrates how the presence detection application can benefit from using power-saving features enabled through dynamic reconfiguration. The present example takes an advantage of the opportunity to save power by reconfiguring the radar sensor to slow down the frame rate. This is particularly beneficial, especially when running in the MICRO_IF_MACRO mode. This mechanism is detailed in the Optimization mechanism section.

Terminal outputs

The information that is printed out is in the following format:
[INFO] Radar state Range bin Time stamp
Current presence state, Current radar setting, New radar setting

Figure 8. Terminal output choosing different configurations

Table 1. Terminal outputs

Parameters	Event type	Description
Radar state	Macro presence	Presence event detected
Range bin	2	Maximum range bin
Time stamp	'4298'	Relative time in ms
Current presence state	0	0: Macro 1: Micro 2: Absence
Current radar setting	10 Hz	10 Hz: Low frame rate 200 Hz: High frame rate
New radar setting	macro/micro	Depends on the detection

Note: Time Stamp is relative to the boot time, which means that when the application boots up first, the time counting starts from 0 ms.

Conversion of range bin to range in meters can be done by using the following relation:

R (range in meters) = (xensiv_radar_presence_get_bin_length() * config.max_range_bin)

For example: If xensiv_radar_presence_get_bin_length() = 0.325, R = 0.325 * 2 = 0.66 m

Configuration parameters

You can configure the application parameters using the options provided on the terminal as follows:

Press Enter to switch from work to settings mode

Type help and press Enter to see a list of configurable parameters as shown in Figure 9

Figure 9. Configuration mode

The following table lists the configurable parameters with valid values:

Table 6. Presence detection algorithm configuration parameters

Key	Default value	Valid values
set_max_range (m)	2.0	0.66 – 5.0
set_macro_threshold	0.5	0.5 – 2.0
set_micro_threshold	12.5	0.2 – 50.0
set_bandpass_filter	disable	enable/disable
set_decimation_filter	disable	enable/disable
set_mode	micro_if_macro	macro_only/micro_only/micro_if_macro/micro_and_macro

Note the following:

Micro motions: Detecting small movements such as finger gestures or small head movements in a typical smart home environment. These include working on a laptop or keyboard, or normal breathing, and blinking of the eyes in sitting or standing positions (in line of sight)
Macro motions: Detecting major movements into or through the field of view (motion detection)

Note: Macro and micro threshold parameters can be adjusted to achieve different levels of sensitivity. The following table summarizes three different levels. For example, high sensitivity means that the solution is more sensitive to smaller movements. You can set any threshold values based on your use case requirement

Table 7. Sensitivity levels with corresponding threshold setting

Sensitivity	Macro threshold value	Micro threshold value
High	0.5	12.5
Medium	1.0	25
Low	2.0	50

Type the command name with the required value and press Enter

If the parameter update is successful, "ok" is displayed; otherwise "command not recognized" or "invalid value" is printed

For details, see the XENSIV™ Radar Presence API Reference Guide.

Debugging

You can debug the example to step through the code.

In Eclipse IDE

Use the <Application Name> Debug (KitProg3_MiniProg4) configuration in the Quick Panel. For details, see the "Program and debug" section in the Eclipse IDE for ModusToolbox™ user guide.

Note: (Only while debugging) On the CM4 CPU, some code in main() may execute before the debugger halts at the beginning of main(). This means that some code executes twice – once before the debugger stops execution, and again after the debugger resets the program counter to the beginning of main(). See PSOC™ 6 MCU: Code in main() executes before the debugger halts at the first line of main() to learn about this and for the workaround.

In other IDEs

Follow the instructions in your preferred IDE.

Design and implementation

Resources and settings

This application uses a modular approach to build a presence application combining a radar driver and presence algorithm library and the following components:

Figure 10. Application overview

The radar configuration parameters are generated from a PC tool and saved in radar_settings.h file. For more details, see the XENSIV™ BGT60TRxx Radar API Reference Guide.

After initialization, the application runs in an event-driven way. The radar interrupt is used to notify the MCU, which retrieves the raw data into a software buffer and then triggers the main task to normalize and feed the data to the presence library.

Figure 11. Application execution

Optimization mechanism

This code example uses a special optimization mechanism to demonstrate the switching between different radar device configurations:

Low frame rate is sufficient for macro movement detection
High frame rate is required for micro movement detection

Therefore, in the default presence detection mode of MICRO_IF_MACRO, the radar device can be configured with a low frame rate by default and only reconfigured with a high frame rate configuration when it is expected to perform micro detection. By implementing such a mechanism, the application benefits from some power-savings.

In the processing task, the optimization object is initialized with the reconfiguration function pointer. The application then runs the presence algorithm normally. The evaluation for the reconfiguration of the radar device is performed in two cases:

The application receives a request to change the presence detection mode (e.g., from MACRO_ONLY to MICRO_IF_MACRO)
A change in the presence detection state occurs (e.g., from absence to macro detected)

The radar device reconfiguration involves rewriting the radar registers with a new set of values, reconfiguring the radar FIFO limit, and restarting the radar frame

Figure 12. Radar activity

Configuration logic

The following configuration logic (see Figure 12) is deployed in the evaluation process when the application is operating in MICRO_IF_MACRO mode.

If the radar is currently configured with a low frame rate and has detected a macro presence, it can detect a micro presence. Therefore, the radar needs to be reconfigured with a high frame rate
If the radar is currently configured with a high frame rate and has detected a macro presence instead of a micro presence, the radar can be reconfigured with the low frame rate to save power
If the radar is currently configured with a high frame rate and there is no presence detected (absence), the radar can be reconfigured with a low frame rate to detect a macro presence

Table 8. Switching to MICRO_IF_MACRO mode

Radar current state	Last detected state	Radar new mode
Low frame rate	MACRO	High frame rate
High frame rate	MACRO	High frame rate
High frame rate	ABSENCE	Low Frame rate

Adding different configurations

Each radar configuration is a structure containing a pointer to a register list, the number of registers, and the FIFO limit. To use a radar configuration suitable for your application, perform these steps:

In optimization_list.h file, edit or add to the existing configurations (i.e., optimizations_list[] and optimization_type_e) in the code example.
Provide the new configuration register list per the example given in radar_high_framerate_config.h and radar_low_framerate_config.h files. You can use the XENSIV™ BGT60TRxx Radar Sensor to generate the register list.

typedef struct {
    uint32_t *reg_list;
    uint8_t reg_list_size;
    uint32_t fifo_limit;
} optimization_s;

optimization_s optimizations_list[] = {
    {
        register_list_macro_only,
        XENSIV_BGT60TRXX_CONF_NUM_REGS_MACRO,
        NUM_SAMPLES_PER_FRAME * 2
    },
    {
        register_list_micro_only,
        XENSIV_BGT60TRXX_CONF_NUM_REGS_MICRO,
        NUM_SAMPLES_PER_FRAME * 2
    },
    {
        register_list_user_config,
        XENSIV_BGT60TRXX_CONF_NUM_REGS_USER_CONFIG,
        NUM_SAMPLES_PER_FRAME * 2
    }
};

typedef enum {
    CONFIG_LOW_FRAME_RATE_OPT,
    CONFIG_HIGH_FRAME_RATE_OPT,
    CONFIG_USER_CONFIG_OPT,
    CONFIG_UNINITIALIZED = 64
} optimization_type_e;
