Mouser Electronics White Paper
This implementation is suitable for user interface applications where
periodic position polling is sufficient. Here, polling an input once every
10 milliseconds is usually enough to avoid perceptions of latency.
In motion control applications, real-time accuracy matters more. To
handle this, the CLB can be set up to trigger an interrupt whenever the
encoder's rotation speed surpasses the predefined limit. This allows
the system to respond immediately, which makes it useful in precision
motor control, where tracking position changes in real time is important
for maintaining smooth and accurate motion.
Regardless of the desired approach, engineers can easily create their
designs using the graphical CLB Synthesizer tool. This tool is included
in Microchip's MPLABĀ® Code Configurator and is also available as a
stand-alone online utility (Figure 5). The CLB Synthesizer provides a
user-friendly interface for configuring the CLB, with example projects
and documentation available to help developers get started. And once
they get started, the PIC16F13145 Curiosity Nano Evaluation Kit offers
an integrated debugger to allow for streamlined and hassle-free testing
and development.
Conclusion
The PIC16F13145 family of MCUs from Microchip Technology offers a
convenient solution to the challenges of implementing quadrature en-
coders. Moving decoder logic into configurable hardware eliminates the
need for external components while also offering considerably better
power efficiency than all-software implementations.
The CLB's flexibility supports everything from simple user interface ap-
plications to high-precision motor control systems, allowing developers
to use the technology for various use cases.
Lastly, by using MPLAB's graphical design tools, engineers can more
efficiently configure and implement this solution, which cuts down
development time and system complexity. These advantages make this
MCU a practical and flexible choice for a variety of quadrature encoder
applications.
