Tiva C GPIOs

fetured

GPIOs are the basic interfaces of any microcontroller. Without GPIOs we won’t have any other way to use a micro and it will be nothing more different than a chunk of well-fabricated silicon. Through them we can interface both transducers or sensors and actuators. We can also connect other devices like a display, external devices and so on. As with any ARM microcontroller, the GPIOs of TM4C12x Tiva C ARM microcontrollers are very elaborate, having many options that are usually unavailable in common 8-bit microcontrollers. The one we are interested in – the TM4C123GH6PMI – is a 64-pin micro with more than 40 usable GPIO pins. Here in this post we will explore the GPIOs of TIVA C micros.

Tiva C Clock System

Tiva C Launchpad External Clocks

The clock system of a microcontroller is a fundamental element. Clock system provides the heart-beat needed to keep applications running in a synchronous manner. In the case of Tiva C micros the clock system is as much as sophisticated and elaborate as with any other ARM micros. In this post we will explore this basic block of Tiva C micros. We will see that the clock system is a network of different clock sources and internal units that are intertwined in a complex but easy manner.
