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 ...

Suppose for a moment that you're an engineer designing a new 8051-based product. Not unexpectedly, the application's code size will greatly exceed the 64KB architectural limit of the 8051's program ...

The 8051 8-bit microcontroller just keeps plugging away, adding new peripherals, speed grades, and packaging. Among the latest advances is Dallas Semiconductor's 8051 implementation that delivers a ...

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 ...

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 ...
