5.1.6.1.3. Non-Functional requirements
The GPIO configuration process should complete in less than 10 milliseconds. |
Each GPIO function must use no more than 13KB of available memory to minimize the impact on system resources. |
Error handling should provide specific status codes (e.g., 0x01 for invalid pin, 0x02 for incorrect mode) to facilitate troubleshooting and debugging. |
The configuration functions should be reusable across at least 80% of different projects, with minimal changes required to accommodate different hardware configuration. |
GPIO pins must function correctly under conditions of up to 10 MHz output speed without failures. |
GPIO pins must handle up to 3.3V logic levels without failures. |
All functions should be documented with clear, concise comments, with a goal of reducing time required for developers to understand or modify the code. |
The GPIO configuration code should work on all 16 pins of each available port (GPIOA, GPIOB, etc.) without any need for port-specific adjustments. |
The system should be capable of providing feedback within 1 second for invalid GPIO configurations or other errors, allowing for rapid diagnosis. |
The GPIO configuration should support up to 4 different peripheral mappings (e.g., UART, SPI, I2C, ADC) per pin to maximize flexibility and usage scenarios. |
Alternate functions and modes need to be matched with the peripheral requirements for seamless operation. |
GPIO pins need to be correctly configured to work with peripherals such as ADC, UART, SPI |
