The intel 8051 series 8bit microcontroller, originally introduced in 1980, remains popular and has had perhaps the longest product life of all such devices. It has become the industry standard for ...

This project contains assembly code (lab2.asm) for interfacing a keypad with an 8051 microcontroller, using the 8255 PPI (Programmable Peripheral Interface). The code handles reading inputs from the ...

As a result, this project is set up as a how-to for others looking to dive further into the world of microcontrollers that don’t have the same hand-holding setup as the Arduino. To take care of the ...

We live in a world surrounded by electronic devices, and microcontrollers are the brains of these devices. Microcontroller programming is an essential skill in the era of the Internet of Things (IoT), ...

FlashRunner™ In-System Programmer (ISP) line from SMH Technologies supports 8051s from CAST; Live 8051 programming demo running in CAST’s DAC booth Woodcliff Lake, NJ, USA and Villotta di Chions, ...

A while back, [Matt] bought a few 8051 MCUs and tucked them away for a future project. He just found these fabulous little chips in a component drawer and decided it was time to figure these guys out.
