Steps are generally as follows: 1. New, the preparation of the program 2. Connected to the emulator or burner, this step may want to set up the emulator or burner, you can look at them to use the instructions 3. Compile the program, this step will automatically detect your program is not correct, if there is a mistake, it is not possible to go to the next step. If you are using an emulator, this step can be run directly after the success of the compiler for online debugging. 4. If you use a burner, then the burner Each software and debugging method will be a little different, but generally this is the case, some of the debugging tool manuals also have a very detailed description. Parameter measurement technology involves a wide range, especially micro-voltage, micro-current, high voltage and to be measured under the circumstances of the signal strength of the great difference between the weak signal to ensure that the weak signal measurement accuracy and to take into account the measurement range of strong signals, there are certain technical difficulties. The traditional low-cost instrumentation in the measurement of voltage, resistance are used to manually select the gear to convert the range. In use, when forgetting to convert the gear, it will cause the meter to lose measurement accuracy or damage. Modern electronic measurement of the system's accuracy requirements are increasingly high and the degree of intelligence is also increasing. Full-range gearless automatic range conversion voltmeter and resistance meter is to ensure that the measurement accuracy does not decline under the premise of eliminating the manual range conversion work, has been widely used. This paper introduces an intelligent multi-meter based on AT89S52 microcontroller. The meter can complete the measurement of DC voltage, resistance and DC current under the control of MCU. The current measurement part uses a simple I/V conversion circuit to complete the test; the voltage measurement part combines the analog switch CD4051 and operational amplifier OP07 to form a programmable amplifier to realize the automatic range conversion; the resistance measurement part also combines the analog switch CD4051 and operational amplifier OP07 to complete the automatic range conversion under the control of the microcontroller. Current, voltage and resistance of the final measurement signals are under the control of the microcontroller by the 12-bit A/D converter TLC2543 for the acquisition of the collected signals by the microcontroller data processing through the LCD (12864) display, the results of the measurements can also be with a serial EEPROM CPU memory and monitor of the X25045 for multiple data storage.
