[Nanjing Post and Telecommunications School Competition] Transistor Amplifier Circuit Module

Overview

This design is an amplifier nonlinear distortion research device controlled by STM32F103ZET6 microcontroller. Taking a transistor amplifier circuit as the research object, the transistor amplifier circuit, waveform selection circuit and test circuit are designed and produced. By connecting the microcontroller, use the screen buttons to control the analog switch in the selection circuit to connect different diode circuits or push-pull power amplifier circuits, and connect the oscilloscope to achieve the output of waveforms without obvious distortion and "top distortion", "bottom distortion", " Four distortion waveforms, "bidirectional distortion" and "crossover distortion", are connected to the microcontroller through a test circuit at the same time. An AD analog-to-digital converter is used to sample and measure, and the total harmonic distortion of the five waveforms is calculated and displayed.

I would like to ask how to write a PCI moden card driver. I am stuck at one place. Please help me solve it.
I have seen Wu Anhe's writing of PCI card drivers, and I also know the program flow entry:: If I insert a moden, what should I initialize? com, registers...? Where should I initialize...? Are the read

How to set PIC16F73's PORTA to a digital I/O port after setting it to an analog input port?
PIC16F73's PORTA can be used as an analog input port. Is it an analog port or a digital I/O when the power is first turned on? If ACDON1 is used to set it as an analog input port, how can it be change
Speculation on the Power Supply Topic of the 2007 National Undergraduate Electronic Design Competition
[i=s]This post was last edited by paulhyde on 2014-9-15 08:55[/i] An inverter circuit is very likely. I would like to know what everyone thinks?
Compilation error. This is the first time I have seen this kind of error. What does it mean?
The program uses UART interrupt and 485 to send commands and receive data. Two arrays are defined to store commands and receive data. This is the first time I encounter this error. What does it mean?
Is there any non-library program for connecting C2000 Launchpad to 485 bus host computer that can be shared?
I have never done this myself, and I don't know how to use the ISO35T module on the c2000 launchpad expansion board.
