8051 Tutorial

Interrupts are powerful features in microcontrollers that allow them to respond to events efficiently. The 8051 microcontroller supports several types of interrupts, enabling it to handle multiple tasks concurrently. In this tutorial, we’ll explore how to use interrupts in the 8051, including their configuration and usage, complete with an example …

Timers are among the most essential peripherals in any microcontroller, and the 8051 is no exception. With two built-in 16-bit timers (Timer 0 and Timer 1), the 8051 can perform a variety of timing tasks, such as creating delays, measuring time intervals, and generating pulses. In this tutorial, we’ll discuss …

We continue with our series on the 8051 with a tutorial on serial transmission. Data communications via the serial port is an easy way for a microcontroller to ‘talk’ with the outside world. Examples of devices that have serial interfaces are sensors, LCDs, EEPROM, SD cards, and RTCs.

In my previous post, I showed you how to set up an 8051 microcontroller for programming using C. This tutorial will be about how to interface with seven-segment displays.

The 8051 microcontroller is much older than the ones featured here. Yes, even older than the PIC16F84A. However, being flooded by messages from students about this microcontroller tells me that universities still teach it. Hence, in line with our goal to teach microcontrollers to anyone, we decided to add the …
