Design of 12V numerical control power supply for single-chip computer

When the power supply of the single-chip computer board was short-circuited, it might burn the single-chip computer. If 3.3V and gnd were short-circuited, the tester would detect a buzzing sound. This did not necessarily mean a short-circuit, but it was possible. There were many condensers, microcontrollers, and possible interface chips between 3.3V and gnd. Any short circuit would cause a short circuit between 3.3V and gnd. During the inspection, the 3.3V related to the chip can be removed and measured again to see if the chip is short-circuited. If it is short-circuited, the chip can be disassembled to measure the resistance between the chip's 3.3V and the ground. You can also measure the voltage of the microchip by welding one of the feet of the microchip's voltage. If the voltage is still connected to the voltage, the microchip may be damaged. In this case, the microchip may need to be replaced. If you are using the smallest system board such as the K60, you can change your own single-chip computer or send it back to the manufacturer for replacement. In addition, pay attention to static electricity protection during welding, otherwise static electricity may break through the chip and cause damage. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

For a 24V motor with a high current, it could generally be controlled by a MOS tube or an IGBT. Relatively speaking, an mos was a more economical and practical choice. You can use a single-chip computer to build an H-bridge drive circuit to drive a 24V brush motor. First, draw the H-bridge drive circuit. In the protues, you can use a high-voltage driver chip like the ICR2101 (24V is considered low voltage compared to the voltage it can drive) to build the circuit. At the same time, you need to consider the addition of some other circuit components, such as the addition of a circuit. Because there was an interelectrode capacity (between the G and S poles) inside the MOS tube, the resistance coming out of the G pole and the interelectrode capacity of the GS formed an RC-charge and discharge circuit. By adjusting this resistance, the rise time of the MOS output from the low level to the high level of the dimming pulse could be adjusted. A parallel connection of the G-pole resistance with a second voltage could make the discharge time of the dimming pulse from the high level to the low level faster, thus affecting the fall time. In addition, when it came to the single-chip processor receiving the signal from the 24V passive switch, the 24V high frequency needed to be reduced to the single-chip processor pin frequency. In the motor control, by controlling the operation of turning on and off the MOS tube in the H-bridge circuit, the motor was controlled and started. For example, through the electromagnetic coil of the contactors in the control circuit, the power supply of the main circuit of the motor was switched on and off to start the motor. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

These simple experiments helped to understand the basic operation of the single-chip computer. To light up the LED lights as an example, you need to understand the settings of the general input and output port (CPU) of the single-chip computer. You need to control the level state of the pins through programming to achieve the lighting or extinguishing of the LED. - When writing code, you must follow the programming specifications and grammar requirements of the selected single-chip computer. For example, in the C language, one had to correctly define variable types, functions, etc. 3. ** Advanced experimental programming ** - As his understanding of the single-chip computer deepened, he tried more complicated experimental programming, such as using ADC (Analogy to Digital Conversion) modules to read the simulated signal, using Pulse width Modulation (Pulse width Modulation) to control the motor speed, and so on.

The following are the general steps and key points of the development of the single-chip electronic scale: ** 1. Hardwares ** 1. ** Main control chip selection ** - He could choose a more common chip like the 8051 single-chip computer. It had 4KB of internal program memory (Scalable), 128-Byte internal data memory (Scalable), multiple bi-directional parallel input/output ports, and other resources to meet the basic control and data processing needs of the electronic scale. - It also has the advantages of low working voltage, low power consumption, strong driving ability, etc. For example, its I/O port is bi-directional and the output circuit is a complementary push-pull output circuit. The external circuit is simple in driving the digital tube display, and its A/D is 10 bits to meet certain precision requirements. 2. ** Sensing and signal processing ** - The sensor was used to obtain physical quantities such as weight. For example, using a pressure sensor to detect the weight of an object usually required a special signal processing chip, such as the HX711 for processing pressure signals (range 0 - 5kg, accuracy 0.1 g). 3. ** display module ** - The 1602 LCD module was used to display the date, time, weight and other information. It was necessary to connect the single-chip computer to the 1602 liquid crystal, including the connection of the data port and the control port. The software programming was also used to initiate and write data into the 1602 liquid crystal. 4. ** Clock module (option)** - If you need to record time-related information, you can use the DS1302 clock chip. It could provide accurate date and time information for the electronic scale. The microchip needed to communicate with it through the corresponding interface circuit to read and set the time. 5. ** Communication module (option)** - If you want to upload the data to the PC display, you can use the 232 serial communication. The single-chip computer had to set up the serial port, including the configuration of baudrate, data bit, stop bit, and other parameters to achieve stable data transmission with the PC. 6. ** Power Circuit ** - It provided a stable power source for the entire system. It was necessary to design a suitable power supply circuit according to the voltage requirements of the selected chip and other electronic components. For example, a voltage stabilizing chip was used to convert the input voltage to a stable 5V or 3.3V voltage to meet the power supply requirements of the single-chip computer, sensor, display module, etc. ** 2. Software ** 1. ** Selection of programming language ** - If you use the 8051 single-chip computer, you can generally use assembly language or C language for programming. For beginners, C language was relatively easier to understand and write complex program logic. - For the PIC-based single-chip computer, you can also use the C language or its specific programming language, but you should pay attention to the differences between the 8051 single-chip computer and the 8051 single-chip computer in terms of instruction set and register usage. 2. ** Program Function Realization ** - ** Initialize settings **: Initialize the ports, timers, and interrupt of the single-chip computer. For example, set the port connected to the sensor to the input mode and the port connected to the display module to the output mode; Initialize the timer to meet the timing requirements (if there is a timing function requirement); Configure the interrupt (if the interrupt is needed to process the sensor data collection or other events). - ** Data Collection **: Obtain weight and other data from the sensor through programming. If the HX711 was used to process the pressure signal, it was necessary to read the processed pressure data (weight data) from the HX711 according to the communication protocol of the HX711 and convert it into an actual weight value. - ** Data processing **: To process the collected data, such as filtering to reduce errors caused by sensor noise. Simple arithmetic average filtering or other filtering algorithms can be used. - ** Show Function **: Show the processed weight, date, time and other data on the 1602 LCD. This required writing the corresponding display function according to the display specifications of the 1602 liquid crystal, converting the data into a format suitable for display and sending it to the liquid crystal display module. - ** Communication function (option)**: If there is a serial communication function, write a serial communication program to send the data to the PC in the agreed format. This included the packaging and verification of the serial port data to ensure the accuracy of the data transmission. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>
