Detailed Description

Ultrasonic 3 Click example.

Description

This example demonstrates ranging with Ultrasonic 3 Click (Chirp/TDK time-of-flight). The example periodically triggers a measurement and prints the measured distance to the USB UART.

The demo application is composed of two sections :

Application Init

Initialize the USB UART logger and the Ultrasonic 3 driver, then apply the default configuration to start the sensor and prepare it for continuous single-shot ranging.

Application Task

Triggers a measurement and logs results (distance, sample number, and amplitude) every 100ms.

Note

Make sure to configure falling-edge external interrupt on INT pin in bsp.c for your selected setup. Currently, only 3 interrupts are pre-configured for the following setups:

MCU Card for STM32 STM32F407ZG (MIKROBUS1)
MCU Card for Tiva TM4C129XNCZAD (MIKROBUS1)
MCU Card for PIC32 PIC32MX795F512L (MIKROBUS1)

Note: If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
