In this tutorial, we will discuss how to use GPIO interrupts which are also known as external interrupts of 8051 microcontroller. We will learn to configure GPIO interrupts as edge-triggered such as positive or negative edge or level triggered such as active high or active low level triggered. Before reading this article, you should know … Read more
In this tutorial, we will learn how to use timers on the 8051 microcontroller to generate a delay. The 8051 microcontroller has two 16-bit built-in timers. We can program each timer individually and configure them as either timers (to generate time delays) or counters (to count events occurring outside the microcontroller). The 8051 timer has … Read more
In this tutorial, we will learn how to use the input and output ports of the 8051 microcontroller. The 8051 microcontroller has 40 pins, comprising four I/O ports. The microcontroller uses 8 pins for specific purposes, while 32 pins are configurable as input and output pins to connect the microcontroller with peripheral devices. Each port … Read more
In this article, we will explore the concept of a watchdog timer and its application in the context of PIC microcontrollers. A watchdog timer is an essential component that ensures the stability and reliability of a microcontroller system. By continually monitoring the system’s operation and taking necessary actions, such as resetting the microcontroller when needed, … Read more
