according to wikipedia to programm this 8051 microcontroller the most common language used is C and assembly. Other high level languages such as Forth, BASIC, PASCAL, PL/M and Modula 2 are also available for the 8051.

For me those languages are too low level and I dont really know any of them. I am more into OO programming languages such as java, c# etc.

Sorry I cannot help you with this topic.
