The HELLO program is a very simple program that prints "Hello World" to the serial port of the 8051. When you can successfully build and run this program, you have used the entire toolset including: The uVision integrated development environment The C51 compiler The BL51 linker and the dScope simulator/debugger. The HELLO project is available in two versions: HELLO.PRJ uses the dScope Simulator for testing MHELLO.PRJ uses a Monitor-51 based environment for testing and runs on a target board like the MCB517 board
