The A31 is based on the 51 microcontroller ADC0809 data collector.
Information sent to you: Procedure. **There are two versions of 78 and 8Version 6, the program is a keil version, written in assembly language. WeChat***MCU**.
Hello everyone, today we are using a 51 microcontroller to design an ADC0809 data collector, and its requirements are as follows:
1. Use assembly language for programming.
2. The ADC0809 is required to detect the ADC value corresponding to the potentiometer and display the ADC value through the digital tube. Note that the ADC values shown here are not converted to the corresponding voltage values.
Also open the ** software, double-click the single-chip microcomputer, and load the program from here. A brief introduction to the basic components of a schematic diagram is available. In the middle is the minimum system of the single-chip microcomputer, and on the left is the crystal oscillator circuit and the reset circuit. The default crystal oscillator is 12 megabytes, double click the microcontroller, and you can also change the frequency of the crystal oscillator from here, but the general default is 12 megabytes.
Point on, with a four-position common cathode digital tube on the top right, an ADC0809 on the bottom, and a potentiometer on the left. By detecting the ADC values at different positions of the potentiometer, they are displayed through a digital tube. You can adjust it, and the further you go to the left, the bigger it gets, and the maximum can be adjusted to 255. Because it's an 8-bit ADC, it's down to the right, so you can adjust it at will. The ADC value is displayed, not the voltage value.
That's it for today, thank you.
