What is a programmer?

MCU:
The programmer in Taiwan is called a burner because the semiconductor industry in Taiwan developed early. After arriving in the mainland, customers call it a “programmer” because it is now called programmer in English. This English name is the same name as the general software programmer, so it is called “programmer”. The programmer is actually a tool for writing data on programmable integrated circuits, The programmer is mainly used for the programming (or brush writing) of chips such as single chip microcomputer (including embedded) / memory (including BIOS).
In terms of function, the programmer can be divided into general programmer and special programmer. The price of special programmer is the lowest and there are few types of applicable chips. It is suitable for programming with one or a kind of special chip, for example, it only needs to program pic series. The full-function universal type can generally cover almost (not all) all the chips that need to be programmed at present. Due to the troublesome design and high cost, the sales volume is limited, and the final price is very high. It is suitable for the situation that many kinds of chips need to be programmed.
The basic configuration of using the programmer to copy the data of the memory is: a computer (the programmer does not have high requirements for the computer, generally speaking, as long as it can run the Windows 98 operating system), a programmer and the driver software matched with the programmer. The general operation steps are as follows: ① connect the programmer with the computer. Different programmers are connected to the computer in different ways. Some programmers are connected to the computer parallel port (printer interface), some are connected to the computer serial port (COM1 or com2), and some use USB interface (such as rf910). In terms of speed, USB interface is the fastest and serial port is the slowest. ② Install the driver software matched with the programmer on the computer, and set the programmer as required. ③ Run the programmer driver software. The figure shows the operation interface of rf910 driver software. Select the memory model. Figure operation interface of rf910 driver software ④ operate the programmer driver software to read the required data stored in the computer as the data source. There are two ways to obtain the memory data source: the first is to find a normal display of the same model as the repaired fault machine, remove the memory, insert it into the programmer, read out the data in it and save it in the computer; The second is to directly use the memory data that has been saved in the computer (it can be the data backup you have done before, the data provided by the manufacturer or the data downloaded from the Internet). ⑤ Insert the blank memory (or used memory) into the programmer, operate the programmer drive software, and the programmer writes the normal data into the blank memory. ⑥ Replace the new memory of written data to the faulty machine.
