The oscilloscope is a must-have for each engineer, and it is also a baby studies. It is very wide. Any periodic physical process that can become an electromatal can be observed with an oscilloscope. It converts the electrical signals that are invisible in the naked eye into a visible image, which is convenient for people to study the changes in various circuit phenomena. Share the design works of 9 oscilloscopics on the Circuit City, see if you have all your fantasies!
1, STM32F103 oscilloscope + signal source simulation information
Perfectly ported to the positive atomic development board without modifying the program.
The software is made based on UCOSIII + STEMWIN 5.26. The display uses a positive point atom 2.4 inch LCD screen. Use a touch screen as an interactive mode.
The acquisitionable frequency is not more than 40 kHz, no flashes. The time interval, the amplitude range, and the upper and lower translation can be selected by the touch screen.
Output square waves, sine wave, triangular wave, frequency, amplitude, and duty cycle are adjustable.

2, 1x1 20MSPS oscilloscope based on PIC32MZ
We are designing a PIC32MZ-based oscilloscope, which is only 1 inch × 1 inches, including an OLED screen.
The project is designed around the PIC32MZ EF processor. We use its internal ADC in a staggered mode to get a complete 20MSPS. We found that we can achieve approximately 1 MHz bandwidth in practice.

6, [embedded course design work] mini-palm oscilloscope, STM32 master
Embedded technical works are STM32-based micropal oscilloscopes, and the core technology is the control technology of ARM chip STM32F103C8T6 and the application of the chip resources and 4.2-inch LCD screen. The micropal oscilloscope identifies the voltage of the signal source by using the STM32 chip as the main control chip, by using the STM32 chip, and sampling the voltage data at a certain sampling period, and stores the chip in the queue. The waveform is displayed in real time by a 4.2-inch display. That is, the implementation of the function can be completed.

9, [Graduation Design (Thesis)] Based on SCM STM32 Control, Android Displayed Portable Digital Oscillator Circuit Schematic, Source Code and Graduation Thesis
The portable digital oscilloscope is performed based on the SCM STM32 controlled and displayed on Android. The STM32 single-chip microcomputer is a very cost-effective processor, up to 72m, which can meet the requirements of this design. The use of Android devices as a display platform is a characteristic of this design. The basic idea of this design is that the data sampled by the ADC is processed by the single chip microcomputer, and then the waveform data is sent to the Android device via Bluetooth. At the same time, since the Android device uses a touch screen, the parameters of the oscilloscope can be set through the touch screen. This design uses Android devices to replace the LCD screen and use Bluetooth to perform data transmission, and fully utilize the hardware resources of the Android device.
