Bringing DSPs closer to you! Realizing Digital Filters with the latest low-end RX140 Microcontroller of the Renesas RX Family!
Renesas RX MCU team has been presenting proposals to make the use of DSP easier.
· Implementing DSP at a low cost
· Visualizing DSP operation
· Proposals for the use of DSP with RX MCUs
DSP has been implemented in various fields such as home electric appliances, industry, and health/medical care. In addition, the range of use is getting wider due to ongoing IoT/Cloud.
On the other hand, DSP is often considered difficult and high cost, so people apparently hesitate to start the development of the system using DSP.
Then, as an example of the use of the DSP to be implemented at a low cost, we have released the sample program of the FIR filter using the latest low-end RX140 RX family MCU.
· Inputs analog signals directly to RX140 (Sampling frequency: around 10 kHz)
· Makes a judgment of the frequency band of the input signal by three FIR filters.
· Displays the judgment result with LEDs on the evaluation board.
· Visualizes input/output signals to/from the FIR filter using the waveform display function of Integrated Development Environment e2 studio.
The sample program is designed to leverage the strengths of the RX140.
· Mounts RXv2 core that can perform high-speed DSP operation
· Utilizes DSP Library for RX Family that maximizes the performance of RXv1/v2/v3 CPU
· Realizes the system with a single chip (A/D conversion, DSP, HMI)
By referring to this sample program, you can develop the system with a DSP application in a short period. The sample program is an example of a simple implementation of the FIR filters, and digital filters can be applied for various applications. (Analyzing sensing data, improving voice recognition accuracy, enhancing power supply quality, etc.)
Please consider developing a DSP system application using the latest RX140 MCU.
