21 Years Experience With Keil Compilers In The United Kingdom

Hitex has extensive experience with using Keil compilers and have distributed them in the UK since 1989. We have published many application notes on using Keil C51 and C166, which are elsewhere on this website. The famous "C51 Primer" book was written by our Mike Beach and it is available for download below. This technical guide to what really counts in C51 programming is used by many universities around the world for undergraduate training.

For the C166, you can download our "Introduction To The C Language On The C166"

Our technical expertise with Keil compilers stems from the fact that we have used them in real embedded projects from engine management systems through data acquisition systems to three phase motor drives. Some of these applications are available for download from this websit

• Expert technical support from professional engineers who have actually used the compilers and that are based in the UK, not overseas..
• A free copy of the Motor Industry Software Reliability Association's "Guidelines For The Use Of C In Vehicle Systems" (worth £25!)
