For small and medium power motor applications, the EPSH-MPC development platform provides current sampling of the isolated analog-to-digital converter AD7403. The external current loop is converted into a corresponding shunt voltage through a shunt resistor and input to the voltage test terminal of the AD7403. The AD7403 outputs according to the clock signal given by CM408F. ADC bit stream, CM408F enables the built-in SINC filter on the input bit stream to calculate the corresponding 16-bit ADC value, and stores the data into the corresponding ring queue through DMA. The host computer software can use the UART-USB port Or obtain the display of data samples through the RS485 port, you can intuitively see the acquisition effect of AD7403, and the collected data can be stored in an excel table to facilitate corresponding analysis of the data.
TOF (Time of Flight) is a key technology in the field of 3D depth detection. The AFE (analog front-end chip) drives the infrared laser to emit modulated light pulses to the detection target, and then uses the image sensor to receive the light reflected from the object, and calculates the distance between the target and the camera by calculating the round-trip flight time of the light. TOF technology can be divided into CMOS TOF and CCD TOF according to the type of image sensor.
The ADI TOF system uses CCD as the image sensor, and can be matched with light sources of different intensities for applications in different distance modes. In addition, ADI TOF is based on a pulse-based test method, which can make long-distance detection easier.
"Electronic dog" is a vehicle-mounted device, also known as "safety warning device". Its function is to remind the car owner in advance of the existence of electronic eyes or speed radar. It allows drivers to increase their driving attention in advance where there are safety hazards, and also prevents drivers from speeding or speeding. Fines and points will be deducted for violations.
Nuvoton has designed many highly integrated single-chip solutions that can be used as integrated parts for future automobiles. Although the cost of ISD15D00 / ISD15C00 is low, it is the best audio quality recording and playback device in its class, allowing everyday low-end cars to have audio-level sounds or voice prompts. By providing smooth communication to the SPI port of the automotive network system, system integration becomes extremely simple. ISD15D00 uses external SPI flash memory audio with built-in regulator PWM speaker driver, analog digital input and output, suitable for multi-language storage devices and audio playback of up to 64 minutes. The ISD15D00 voice macro is designed for situations where, for example, the language of the external flash memory changes but the application software does not.
Voice prompt warnings are components used in today's high-end luxury cars. Whether they are dashboard warnings, such as speeding, oil, water level gauges, temperature/heat, tire pressure warnings or pedestrian warning sounds for electric vehicles, they all use shared sound chips.
