GPIO Fundamentals GPIO (General Purpose Input Output) is a common peripheral that can be configured into 8 distinct input/output modes. Pin output voltage ranges from 0V to 3.3V, and pins marked with FT are 5V-tolerant, meaning they accept 5V input while still outputting 3.3V. In output mode, GPIO c...

Cross-File Variable Sharing via UARTTo dynamically control the pulse width of GPIOA, pulse width of GPIOB, and the interval between them via serial commands, declare the configuration variables in the UART source file:int pulseWidthA = 20; int pulseWidthB = 20; int pulseGap = 20;Access these variabl...
