The Development of Single-Chip Computer Scale
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>

Single-Chip Coupled Circuit Diagram
As for the single-chip coupled circuit, in some electrical control products, the input circuit part involved coupling-related content. For example, when the various control signals of traditional electrical equipment are converted into digital signals that match the input/output port of the single-chip computer, the control signals input by the user equipment to the single-chip computer (such as the switch output of the limit switch, the operation button, etc.) are converted through the input circuit, where the input circuit has a coupling-related function. There was also the circuit diagram of the optical coupler-driven relay in the circuit of the single-chip drive relay. The optical coupler-driven relay played a role in the circuit, but the specific circuit diagram needed to be consulted in special documents, such as the circuit diagram of the optical coupler-driven relay (optical coupler/UL2803/switch circuit) and other related information. In addition, the document on the design method of the commonly used drive and coupled circuit of the single-chip I/O for the characteristics of electrical control products may have more detailed design content about the single-chip coupled circuit, but it did not directly give a detailed circuit diagram. <a href="/?from=ask_words" style="color:red" target="_blank">Read more exciting novels for free</a>

Motherboard design and single-chip development
The design of a computer motherboard was a complicated process that involved many aspects. In terms of board layer setup, there were signal layers (such as the TOP layer, Inner Layer3, Inner Layer4, Inner Layer5, Bottom layer, etc.), power supply layers (VCs), and GND layers. Different layers had different functions. For example, the signal layer could be used to place components and route wires. The power layer was mainly a power network. During the design, the layout of electronic components had to be considered for power separation. The GND layer was connected through a via. In terms of wires, there were serpentine wires (used to make the length of the parallel data wires consistent), differential wires (requiring the length of the two wires to be the same and the distance to maintain a certain distance), large wires or wide wires (usually power wires), and so on. The component layout was usually done in a module design, where electronic components that achieved the same function were placed together to shorten the length of the wires and facilitate the layout. The development of a single-chip processor was a comprehensive project. First of all, the model and functional requirements of the single-chip computer should be determined according to the actual needs, and then the overall system architecture should be designed. In terms of hardware, it was necessary to draw circuit schematics, make printed circuit boards, and select components.
