The following is excerpted from the ARM cortex-m3 authoritative guide Overview programming on CM3, you can use both C and assembly. There may be other languages in the compiler, but most people will still be in C and the Assembly of the world cruising. C and the assembly are Chang, cannot replace each other. Use C to develop large programs, while compilations are used to perform special tasks. When do I use the assembly? If the project is relativel

************* ************* I. Role of master and slave: 1. It can be used as a backup method. 2. read/write splitting to relieve the pressure on a database II. Environment: OS CentOS5.5 DB MySQL5.5.3-m3 To install CentOS5.5, see Install MySQL5.5.3-m3. Iii. MySQL master-slave backup Principle Binlog is provided on the master, Slave extracts the binlog from the master through the I/O thread and copies it to

It took a long time to use M4 (NXP), but it was annoying to find that the program crashed and could not judge the location of the crash, previously, I saw an article about how to view the stack content by checking the SP LR and other registers. Also look at the address in memory to find the function address, then look at the assembly code. It is very troublesome. The ARM7 kernel is better to judge. (The M3 kernel is not verified. The same knowledge sh

% RHTemperature: 0001 1000 = 18 h = 24 ℃ Data Sequence diagram: After the user's host (MCU) sends a start signal, the dht11 is switched from the low power mode to the high-speed mode. After the host's start signal ends, the dht11 sends a response signal to send 40-bit data, trigger a message collection. Signal transmission. According to the chip time sequence diagram, we can see that this chip involves microsecond operations, so the M3 system tick re

Tags: embedded CPU Project ManagementIt should be said that the old has been in contact with cortex-M3. I did not expect to be involved in embedded systems before. As a result, I chose project management as a mentor. No nonsense. The matching environment is simple and pure silly. However, I am confused by my own carelessness. I remember that some time ago, I had to stay in the lab all night and I was drunk. The night in the north is extremely cold, no

The new IBM 3650 m3 requires Debian and the latest Debian 507 network installation disk. A file called bnx2-09-4.0.5.fw was missing when scanning the hardware The first time Debian was installed, I found that there were few files. I checked it carefully. It turns out that this no-free file cannot be placed on the installation disk because of copyright issues. Go to the Debian website and find Http://cdimage.debian.org/cdimage/unofficial/non-free/f

For a person who first came into contact with IBM servers, it may be a bit difficult. The previous week, because a hard disk on the IBM server was broken, I found that the problem of converting 5300-to was reported for the X Series servers, you need

Lspci-list all PCI devices Popularization of pci: PCI (Peripheral Component Interconnect) is a bus standard that connects the motherboard of an electronic computer and external devices. Common PCI cards include NICs, sound cards, modem, TV cards, and disk controllers, as well as USB and serial ports. The original video card is usually a PCI device, but soon its bandwidth is insufficient to support the performance of the video card. PCI graphics cards are currently only used when an additional ex

I spent some time at home in the past two days. I picked up Mio that I haven't played with for a long time and searched the internet. I found that many foreign websites and individuals are playing with Mio, and c220 is the lowest level.Many small programs are provided on the Internet and cannot be run on mio, but the program can be run on a PC through the Pocket PC simulator. There are roughly three errors:1. Run the following error: "XXX is not a val
