1. Select the MCU model (such as STC89C52RC)
2. Add the Hex file to be downloaded
3. Select the COM port. You need to find the COM port corresponding to the USB to serial port in the computer's device manager (this advantage can only be displayed after the driver is installed). The rest are left as default.
4. Leave the default as default.
5. Click the download button. Note that you must click the download button first and then power on the MCU to successfully download. Download address of flash magic:
http://www.51hei.com/f/Flash Magic.rar ISP mode:
1. Select COM4 port (same as before), select a lower baud rate, select P89V51RD+ as chip, and the last two items are default.
2. Select the second option: ERASE BLOCKS USED BY HEX FILE
3. Select the HEX file to be downloaded
4. Select the first option: VERIFY AFTER PROGRAMMING
5. Power on the MCU first, click the START button, and reset the MCU after the dialog box appears. To let the MCU run the program, press the reset button again.
ICE mode:
1. In flash magic, click ISP and select ENABLE SOFTICE in the drop-down menu. After the dialog box pops up, reset the MCU, pop it up again, and reset it again.
2. In the keil software, click OPTION FOR Target, select keil monitor 51 under the DEBUG option, select COM4 port in setting, and click OK.
3. Click start debug session, enter the simulation state, click the run button to start the simulation, reset the MCU to stop the simulation, and then click stop debug session to exit the simulation
4. In the lower left box in the third step, click WATCH #1, click F2 to enter the variables to be viewed, and set breakpoints in the program, debug the program step by step, and view the values of each variable.
