The TIDA-00403 reference design uses off-the-shelf EVMs for ultrasonic distance measurement solutions using algorithms within the TLV320AIC3268 miniDSP. In conjunction with TI’s PurePath Studio design suite, a robust and user configurable ultrasonic distance measurement system can be designed with the click of a mouse. The ultrasonic burst generation characteristics as well as detection algorithms can be user modified to fit specific use cases in industrial and measurement applications allowing users to overcome the limitations of other fixed function sensors while simultaneously increasing reliability of the measurements. Two GPIOs on the TLV320AIC3268 are automatically triggered indicating a transmitted and received ultrasonic burst. With a host MCU monitoring these GPIOs, the time of flight can be extracted.

Light Detection and Ranging (LIDAR) systems use the time taken by the light to fly back and forth to an object in an effort to measure the distance to this target. The TIDA-00663 reference design shows how to design the time measurement back-end for LIDAR based on Time to Digital Converter (TDC) as well as associated front-end. The LIDAR pulsed time of flight reference design can be used in all those applications where measuring distance to the target by establishing a physical contact is not possible. Typical examples include measuring presence of objects on a conveyor belt in logistic centers, ensuring safety distances around moving robot arms among many others.
Возможности:

LIDAR pulsed time of flight measurement Distance resolution at system level <1cm TDC resolution of 1.65cm and a white noise of 1.05cm RMS TX energy: 70W peak over 40ns

The TIDA-00666 TI Design enables Bluetooth Low Energy (BLE) communication powered from a 2-wire 4- to 20-mA loop. For industrial process control instruments, analog 4- to 20-mA current loops are commonly used for analog signaling, with 4 mA representing the lowest end of the range and 20 mA the highest. The TIDA-00666 reference design measures humidity and temperature and it is broadcasting the measured values with Bluetooth Low Energy. The TIDA-00666 design is loop powered and the current value on the loop is changed according to the humidity value (0% is 4mA and 100% is 20mA).
