Operation example

Take the serial communication experiment on the ME500B microcontroller development system as an example:
Write the program to AT89S51 or AT89S52. The usage routine is a serial communication program on the ME500 CD, located on the CD: ME500B Experimental Routine 51 Series 1. Basic Exercise Part 1.7 The serial communication digital tube displays two programs, ASM and C51, either one is acceptable.

After the program is written, switch the SW2 switch on the ME500B to the simulation position, click the "Serial TT" icon on the toolbar, the serial TT software will pop up, and set the correct port and baud rate as shown below.

Right-click on the information receiving box and press the settings as shown below

Enter "123456" in the sending box as shown below, and press the manual sending button. The computer sends 123456 to the microcontroller. After receiving the data, the microcontroller sends WILLAR to the computer.
