Operating Procedur of 233 chips
233 chip is a low-cost single-chip microcontroller. Its main features are as follows:
1. The operating voltage range is 2.0-5.5V, and the single-chip microcontroller can work properly within this voltage range.
2. The frequency of the controller can reach 8MHz and can be flexibly adjusted by selecting different oscillator frequency.
3.The clock of the controller is built in, and the working frequency of the program can be accurately calculated by the clock.
4. All I / O ports are TTL / CMOS-level compatible, providing 14 input / output ports, each of which can perform multi-channel control and also be used for interrupt functions.
5. The memory is also built in, with a total of 8K (max) of Flash ROM and 8K (max) of RAM, which can store data and program code.
6. Internal has various control and serial bus interfaces, such as UART, IIC, SPI and so on.
7. Equipped with two 16-bit counters/timers and one PWM generator, it can be used to generate interrupt signals and output specific voltage pulses.
The following is the usage description of 233 chip:
1. Debugging. Debug the circuit, set parameters, and the parameters set for each function block and port correspond to the instructions of the program writing.
2. Setting parameters. Pay attention to setting each parameter correctly. If it is not correct, the controller may not work properly or cause damage to the chip.
3. Program writing. The program must be constructed step by step, from the subdivision of the process to the overall programming. The structural part of the program must be presupposed when writing, and all condition judgments must be programmed.
4.In addition, the chip should be protected from static electricity. The static electricity destroyed by human body may make the chip unworkable, do not touch the pin of the chip at will, and handle it carefully. Before powering on, it is necessary to pay attention to whether all components and wiring are correct.
5. At the same time, it is also necessary to ensure that the power supply voltage is within the range that the chip can withstand, otherwise, it may lead to malfunction or damage of the chip.
In short, operating 233 chips requires a comprehensive process including debugging, setting parameters, programming and protection. Pay attention to the details in the whole process and make the controller work better.
