Main Application Software - ST AEKD-AICAR1 User Manual

If you want to read from the log file, use the following instructions:
•
void get_offset_LOG(void)
•
void collect_data_LOG(void)
•
float* get_diff_acceleration_buffer_IMU(void);
4.3.2.2 AI sensing node network middleware
This middleware is responsible for:
• initializing the LSTM neural network: void init_ai_sensing_node_CNN(void)
• returning the LSTM neural network to initial data: void deinit_ai_sensor_node_CNN(void)
• running the LSTM neural network: void run_ai_sensor_node_network(void)
4.3.2.3 LCD display middleware
The LCD display middleware is responsible for the icons and messages to display according to the results of
LSTM neural network. It is responsible also for:
• initializing the LCD display: void infotainment_system_init(void);
• printing a message (with a specific color) and drawing an icon: void display_print(uint8_t msg,
uint16_t color);

Main application software

The AEKD-AICAR1
• Acquisition
• Real-time calculation (default)
• Offline calculation
4.3.3.1 Acquisition
This working mode is used to perform an LSTM neural network training.
If #define ACQUISITION is applied on the head of main application:
• the calculation of the LSTM is deactivated
• the serial protocol is initialized to send three axis acceleration samples with a baud rate of 38400 bps
4.3.3.2 Real-time calculation
This working mode is used when the ECU is installed on a car and the LSTM neural network is already
pretrained. To activate this working mode, comment the #define ACQUISITION.
At power-up, press the SW_1 button on the AEK-MCU-C4MLIT1. If the button is well pressed, then the LED_2
switches off.
4.3.3.3 Offline calculation
This is the default operating mode at power-on.
The LSTM neural network is computed on the log file.
To activate this working mode, comment the #define ACQUISITION.
At power-up, press the SW_1 button on the
UM3053 - Rev 1
application has three operating working modes:
