The provided information gives a clear
overview of the capabilities and intended usage of the Sitara™ MCU+ and MPU processors in this application note:
- Integrated Flexible ADC
Interface: Sitara™ MCU+ and MPU processors
offer a programmable multi-channel SPI ADC interface via PRU-ICSS, which are
versatile and adaptable in interfacing with external ADCs.
- 4-Channel ADC Sampling: The
application note demonstrates the ability to capture data from four ADC channels
concurrently. This synchronous sampling allows for synchronized acquisition of data
from multiple sources, crucial in various sensor-based applications.
- Edge Processing and FFT:
Following data capture, the processors are programmed to execute edge processing
tasks, which can include data preprocessing or other initial calculations.
Furthermore, the processors are capable of performing Fast Fourier Transform (FFT)
computations on the acquired data. FFT is instrumental in transforming data from the
time domain to the frequency domain, enabling advanced signal analysis and pattern
recognition.
- Data Transmission via MQTT:
The application showcases the capability to transmit the processed data to a gateway
or cloud-based service using the MQTT (Message Queuing Telemetry Transport)
protocol. This allows for efficient and reliable data communication, often employed
in IoT (Internet of Things) and sensor data monitoring applications.
In summary, this example illustrates how
the Sitara™ MCU+ and MPU processors can be employed for
advanced data acquisition, processing, and transmission tasks, making them appropriate
for a wide range of applications requiring real-time data analysis and connectivity with
external systems or the cloud.
