As 32-bit microcontrollers become more complex, the degree of configurability for each general purpose input/output (GPIO) pin and peripheral increases significantly. A highly configurable GPIO and peripheral set should give you additional design flexibility instead of adding design hurdles. Having access to an easy-to-use configuration interface paired with software tools that graphically configure a device’s pin-out and peripherals enables you to quickly determine an application’s pin-out and generate code. This paper takes a closer look at how an MCU configuration utility with an intelligent GUI can ease the application development process and ultimately accelerate time-to-market.
