MCU analog EEPROM basic function If your MCU's flash is large enough. And your MCU provides self-programmed flash instructions. You can simulate an EEPROM area via Flash. Used to store data.This document refers to the St company's AN2594 documentation. Use the examples provided by St. Designed to learn how to simulate a piece of EEPROM using Flash.By the table we get a comparison of erase times. The intern

Other Single-Chip Microcomputer do not reset SM2 because the received address data is different from the preset data, then they will not be able to receive the data sent from the MCU in the next cycle (not the address data) and will continue to wait for the arrival

board power-on experiment" (the program of the current flash microcontroller can be burned more than 1000 times ), such a complete set of experimental equipment (excluding PCs) is only a few hundred yuan, which is sufficient for most people who are already working. Readers with better economic conditions can consider using online simulators (ICE) for experiments, so that they can learn more intuitively. In short, what we talk about here is the author's personal experience. We hope that the most

The newly purchased bc04_ B demonstration board communicates with the mobile phone via serial port Bluetooth, And the sending and receiving are correct. MCU Communication baud rate 9600 Connect the serial port of the single-chip microcomputer to the RS232 serial port of the Bluetooth demonstration board. After Bluetooth is enabled, the Bluetooth connection automatically disconnects the transmission data. Analysis: The study found that the Bluetooth

wrote until the power is down. If the execution of the main function ends, unpredictable results will occur.In actual experiments, the STC microcontroller resets and re-executes the program. It may be a coincidence that this is not explicitly stated in the official chip manual. With a rigorous scientific attitude, we do not use this unofficially confirmed feature to develop our programs. Program reliability is very important, which should be paid attention.Imagine if you use a single-chip micro

Initiated: December 27th, 2012 Preface The single-chip microcomputer, once fascinated for a while in the university era, was dropped after graduation. After many years, the interest in electronic production began to rise again, so the MCU was replayed. It is enough to make use of hundreds of RVs, tiny13, 2313, and ipv8. But with a single-chip microcompu

Among them, P1 ^ 0 and Le are connected, segment selection (determines what the digital display is), and bit selection (which one of the digital tubes is bright) is determined by the 138 decoder. Let's write the program first: # Include // T

After the STM32 MCU is interrupted, the main function is returned instead of being executed, As a company project, a function is implemented by the machine when performing a function (this work lasts a long time). If you want to cancel this job, you can reselect it. After thinking for a long time, my colleague reminded me that an external interrupt can be added to the program and the software can be reset during the interruption. The following two sen

The basic usage is the above procedure. The key is to pay attention to timing issues. Readers can download 1602 LCD data online, and then ponder over this program. Note: write commands can be understood as setting display properties; write data can be understood as the data you want to dis

I have been using a single-chip microcomputer for a while, but I am also familiar with the use of some modules. I am not very familiar with the working principle of the single-chip microcomputer. Therefore, it is difficult to study in depth at last. At best, we are familiar with the programming of C51. To understand the working principle of a MCU, it is necessary to understand assembly. In the programming process, the most important thing is timing! W

, it is not difficult to understand why the program runs and runs data as commands. Iii. Second functional usage of P0 port, P2 port and P3: The second functional usage of P0 port, P2 port, and P3 port is often puzzled at the beginning of school, it is believed that there must be a switching process between the second function and the original function, or an instruction. In fact, the second function of each port is completely automatic, and no command is needed for conversion. For example, P3.6
