Principle of Work
The Teensy 4.0 operates by executing code stored in its flash memory using the ARM Cortex M7 processor. When powered on, the program is loaded into RAM and executed at high speed. The processor communicates with onboard peripherals such as digital and analog pins, timers, communication interfaces, and memory to perform tasks defined by the user code. High clock speed and advanced architecture allow complex calculations, real time signal processing, and fast communication with external devices.
