The 8051 was an 8-bit Harvard-architecture microcontroller first put out by Intel in 1980.  They’ve since discontinued that ...

Some people think that programs for microcontrollers like the 8051 that have limited program memory must be written in assembly language rather than a high-level language like C. The executable code ...

Although 8051-compatible microcontrollers with SPI ports are available, a lower-cost device with an SPI port bit-banged through GPIO pins often suffices. The code shown here takes advantage of ...

Despite being 40 years old, 8051 microcontrollers can still serve useful roles in modern systems. But integrating 8051s in today's systems with their de facto standard AMBA® buses, wider datapaths, ...

Microcontrollers continue to improve their networking capabilities. CMX's DHCP Client, one of these improvements, eliminates the need to use fixed IP addresses on a range of 8- and 16-bit ...
