EdSim51’s Guide to the 8051 is a comprehensive exploration of the core of one of the world’s most popular series of 8-bit microcontrollers. It begins with the very basic operations of any microcontroller, then focuses on the 8051 itself, including the on-chip timers and serial port, interrupts, parallel ports and peripheral interfacing. All are explained in detail, with the use of many examples and diagrams.

Full colour screenshots of the EdSim51 simulator are embedded throughout the text, illuminating the topic under discussion. In this way, the reader gets to see exactly the effects a running assembly program has on the controller’s registers and on the attached peripherals. The reader is encouraged to download (for free) the simulator from www.edsim51.com and try out the book’s many examples.

The penultimate chapter contains many more examples in assembly, designed to exercise the simulator’s peripherals, while the final chapter contains an example written in C. This C program contains a driver for the HD44780 LCD module, designed for writing to the module as interfaced to the simulator.
