Solemn statement: This is an open source product and can only be used for learning and communication. Commercial use is strictly prohibited, otherwise we will pursue legal liability. Your use of our source code indicates your acceptance of this statement. Qdso is a well-designed pocket oscilloscope with 40M bandwidth, 200M sampling rate and 3.5-inch TFT color screen. The overall design controller uses nios ii soft core; AD9288-100 cross sampling rate reaches 200M real-time sampling, and the display part uses RA8872 that supports double buffering and 2D drawing acceleration to achieve high-speed waveform drawing and display. And we will make the source code and detailed tutorials public for everyone to DIY and learn from.
This design mainly uses AT89C51 as the control core, which is composed of Hall sensor, LED digital picture tube, HIN232CPE level conversion, and RS232. The measurement speed system of the microcontroller and the serial communication between the PC and the microcontroller are introduced in detail. Give full play to the performance of the microcontroller. The focus of this article is to measure the speed and display it on the 5-digit LED digital tube.
Stepper motor control based on 51 microcontroller
The microcontroller uses MCS-51 series 89C51 (one piece), 74LS244 and 74LS373 (one piece each), inverting driver ULN2803A (one piece), and operational amplifier LM324 (one piece)
Digital voltmeter based on microcontroller (circuit diagram)
The MSP430 microcontroller is used as the detection and control core of the car; a photoelectric sensor is used to detect the black belt on the road, and the feedback signal is sent to the MSP430 microcontroller, so that the MPS430 microcontroller controls the car to drive at a predetermined speed in each area according to the predetermined working mode, and The MSP430 microcontroller can control driving in different directions depending on the working mode selected; the Hall element A44E is used to detect the driving speed of the car; the 1602LCD is used to display the driving time of the car in real time. After the car stops driving, the driving time, driving distance and each speed zone of the car are displayed in turn. Travel time. This design has a simple structure and is relatively easy to implement, but it is highly intelligent and humane, and reflects intelligence to a certain extent.
