Technical requirements

For embedded programming in C, we will use Keil MDK, which provides a software development environment for a wide range of ARM Cortex-M-based microcontroller devices. MDK provides the very easy-to-use µVision IDE, an Arm C/C++ compiler, and other libraries. You can download Keil MDK from the following URL: https://www.keil.com/download/. Let's take a look at the following steps:

1. Download the following three executable files. You may not find the files with exactly the same names, but they will be somewhat similar:
   • mdk526.exe: This provides a development environment for ARM devices.
   • c251v560.exe: This provides development tools for all 80251 devices.
   • c51v959.exe: This provides development tools for all 8051 devices.
2. Double-click on these executable files one by one and follow the setup dialog boxes to install these three Keil products.
