5.1.1.1.3. Non-Functional Requirements
The GPIO pins shall change state with a latency of no more than 1 ms when transitioning between high and low states. |
GPIO pins shall trigger interrupts within 5 ms when a state change (e.g., button press) is detected. |
GPIO pins shall operate within a temperature range of -40°C to +85°C. |
New GPIO pins shall support all existing functionalities (input, output, PWM, ADC) without requiring significant changes to the existing software logic. |
The GPIO module shall be compatible with a range of microcontrollers and development platforms, including STM32, Arduino, and ESP32. |
GPIO pins shall support low-power modes during inactive periods, minimizing power consumption in applications such as battery-powered sensor devices. |
The GPIO pins shall function reliably in environments with electromagnetic interference. |
The latency between setting an output signal on a GPIO pin shall not exceed 1 ms. |
