No More Debug GPIOs! – Streamlining Data Measurement with EVRICA

EVRICA is a data monitoring tool that enables fast, real-time visualization of memory variables and parameters (previously viewed using methods like printf). It continuously acquires and displays data, such as motor rotation control parameters, as waveforms or numerical values—all without stopping the user system or modifying the program.

Previous methods for data measurement
Measurements with oscilloscope or logic analyzer using free GPIO pins.
However, the number of available pins is limited, requiring repeated cycles of source code modification, build, download, and measurement.

The EVRICA Method: A Novel Approach to Data Measurement
EVRICA directly refers to variables and can measure up to 1,024 points without modifying the sources.
