The 8051 Microcontroller kit is a professional design single board computer. The intention for this design is to make a cheap microcontroller trainer for school students. With the hex monitor program, student will learn how to program the 8051 microcontroller using hex code. Machine code programming is the basic for learning real microcontroller hardware and instruction operation.Here is the example:Address hex code comment
9000 04 INC A increment accumulator register
9001 01 00 AJMP 9000 jump back to 9000We can test this small code by entering hex code 04, 01 and 00 to memory at location 9000, 9001 and 9002.Then test it with key STEP running, we will see the binary counting up at the 8-bit debugging LED. This will teach student binary number counting. They will see the real operation and how computer counts the binary number.
