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 ...

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 ...

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 ...

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 ...
