SoftwareIntroduction

Keil C51 is a C language software development platform for 51 series compatible microcontrollers.

The development toolkit provided by Keil includes a C language compiler, macro assembler, linker, library management functions, and a comprehensive simulation debugger, all seamlessly integrated through the uVision IDE.
