In this tutorial, we will discuss TM4C123 Timer interrupt programming ARM Cortex M4 microcontrollers. Firstly, we will discuss applications of timer interrupt with one example. We will use a TM4C123 Tiva C launchpad for demonstration purposes. It comes with a TM4C123GH6PM microcontroller. The general purpose timer module TimerA module will be configured and initialized to … Read more
Interrupt processing in ARM Cortex-M microcontrollers is a critical aspect of how these devices manage real-time tasks efficiently. In this tutorial, we will discuss the sequences of steps that are performed by ARM Cortex M processor during interrupt processing. In other words, how ARM Cortex-M microcontroller handles interrupt or exceptions. Recommended Components The following components … Read more
In the last tutorial, we learned to use UART communication modules of TM4C123G Tiva C Launchpad. We have seen a demo to transmit and receive data between the computer and TM4C123G Tiva C on UART5 port using a busy-wait or polling method. In this tutorial, we will see how to make the UART receiver port … Read more
NVIC is an on-chip controller that provides fast and low latency response to interrupt-driven events in ARM Cortex-M MCUs. In this tutorial, We will explain the role of the nested vectored interrupt controller (NVIC) in interrupt handling requests of ARM Cortex-M microcontrollers. At the start, we will explain the exception and interrupt concepts that are … Read more
In this tutorial, we will talk about the interrupt vector table. Firstly, we will define the interrupt vector table (IVT). Secondly, we will see the role of IVT for interrupts and exceptions processing in microcontrollers or microprocessors. After that, we will see the interrupt vector table of TM4C123G ARM Cortex M4 microcontroller. Almost all modern … Read more

In this tutorial, we will learn to use binary semaphores in FreeRTOS using Arduino. First, we will see the introduction of binary semaphore and a few applications. After that, we will discuss FreeRTOS API functions that are used to create and manage binary semaphore with tasks and interrupt service routine. In the end, we will … Read more
In this tutorial, we will go through an analog to digital converter or ADC module of pic microcontrollers. Almost all pic microcontroller series such as PIC10F, PIC12F, PIC16F, PIC18F, and PIC32 controllers have built ADC Modules. But its size depends on the device from which category/ series, you are using. In this tutorial, we will … Read more
