? What is the final positioning of your product?If the product has a large profit margin and the cost of MCU is limited, you may wish to upgrade the product to a higher level, which is also a promotional material and leave room for subsequent upgrades.If the product needs to be carefully calculated and the number of products is huge, saving 1 cent can bring huge profits, then MCU is enough. Even if development is inconvenient, it is only a single expense, moreover, Chinese engineers are not expe

MCS-51 Microcontroller in the physical structure has four storage space: 1. In-chip program memory2. Off-chip program memory3. In-chip data storage4. Off-chip data storage But logically, from the user's point of view, 8051 Single-Chip Microcomputer has three storage spaces: 1. 64 K program memory address space (movc)2. Address Space of the On-chip data storage of 256b (mov)3. and 64 K off-chip data storage address space (movx)When you access three dif

There was a difference in the early 15, and now I'm back in the garden ... The work is busy on the one hand, another really long time did not engage these things.Originally wanted to make a time-sharing operating system on the 8051 microcontroller, so read the next 8051 assembly under the Code, the summary record is as follows:LJMP c:0149//long jump to 0x0149 address start execution command, this command is

As the functionality of the project continues to increase, the program code size is constantly rising, and when more than 64KB, consider introducing the bank into the system.Before you tell me how to add a bank function to an existing project, let's talk about the background of its existence.8051 is based on the Harvard architecture. Code memory is 16-bit addressing, and data memory is 8-bit addressing. This separate addressing feature is suitable for

Putchar in Keil C, take 8051 as an instance, putcharkeilIn Keil C, it is necessary to implement char putchar (char c), or the powerful function printf wocould not work.We shoshould notice in here: new line command for serial output be "\ r \ n" (line feed: LF, 0x0a + carriage return: CR, 0x0d ), not only "\ n" in Keil C.I do not want to write too much tedious word in here, below is my putchar code for 8051,

Contact SCM has a few years of time, has been focused on how to write some applications on a single chip microcomputer, how to start the knowledge of little, ashamed ashamed ... Today, I have to tidy up a bit, deepen the understanding of the SCM, such as why the definition of the data area of the variable restart the initial value of 0. When the MCU is powered on, it will execute startup. The instructions for the A51 file, I analyzed the instructions in this file in a project where I did the fol
