Port 2　　　　Lpc_gpio2->fiopin = ~ (13); // bit 3 Output 0 for Port 23, port bit with outputRefer to the fifth chapter of the cortex-m3 authoritative guide, the 5th section with the Operation (page 87 ~92).To simplify the bit-band operation, you can define some macros. For example, we can create a macro that converts a "bit with address + bit number" to an alias address, and then creates a macro that translates the alias address into a pointer type.// 1

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

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

Background: RAID is a Redundant Array composed of multiple low-cost disks. It appears as an independent large storage device in the operating system. RAID can give full play to the advantages of multiple hard disks, increase the speed of the hard disk, increase the capacity, and provide Fault Tolerance functions to ensure data security. In the case of any disk failure, you can continue to work, the disk will not be damaged. RAID can be divided into soft raid and hard raid. Generally, medium and

Cortex-M3 learning and debugging of stm32f10x UART In the process of learning the stm32f10x Development Board, the first learning routine is the UART Printing program. Due to the previous experience of single-chip microcomputer, UART programming is not unfamiliar, however, in order to lay a solid foundation for programming, the routine should be analyzed and introduced in detail, hoping to discuss with those who share common interests.1. stm32f10x UAR

It uses lwip1.3.2 as the TCP/IP protocol stack. TI's serial port to Ethernet module can quickly convert serial transmission to Ethernet transmission. The module includes a microcontroller based on ARM cortex m3, a pai

byte in length, many other commands are 2 or 3 bytes in length. This is usually the case for a 16-bit architecture, where some commands may occupy 6 bytes or more memory.ARM Cortex-M3 and Cortex-M0 processor leverages ARM Thumb-2 technology that provides excellent code density. With Thumb-2 technology, the Cortex-M processor can support the fundamental foundation of 16-bit Thumb commands that have been extended to include more powerful 32-bit command

I am using NXP cortex-m3 chip LPC1768 as the master chip, after repeated research and experiments, modify startup. the size of stack_size and heap_size in s Code does not help. However, there is a strange phenomenon, that is, the single-step debugging can only be executed once, and the results obtained this time are correct, then there will be a hardware error immediately and an endless loop of hardware errors will be entered into the assembly languag

The stm32-M3 has a system time base timer, which is a 24-bit descending counter. After the system time base timer is set and enabled, the counter is reduced by one every time the system goes through a clock cycle. When the counter is reduced to 0, the base timer automatically loads the initial value, continue to count down, and the internal COUNTFLAG flag will be set to trigger the interruption. The system time base timer function is simple, and only

This version of MySQL continues to improve the InnoDB Storage engine, mainly including: The InnoDB Storage engine is upgraded to version 1.1.1, which is also the latest development version. InnoDB uses a hash table to store redo logs during restoration. In 64-bit systems, the hash table size is 1/8 of the buffer pool size. To reduce memory usage, the size of the buffer pool for the hash table is adjusted to 1/64. If it is a 32-bit system, it is 1/128. In the slow query log, the Rows_examine

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

There is no doubt that this is the best story I've read about Amazon in the past year--and we can almost say it's the third-star technology industry after Apple and Google, though it's still a distant third. Very interesting, it is good because it did not get the official Amazon interview. This forced the author to conduct a full-scale survey, which presents a dangerous relationship between

sell hundreds of thousands of dollars of big-ticket goods, He took the money and fled. What's more, they also register ebay stores at other people's addresses, and they find their personal information and home addresses abused by criminal gangs when the FBI finds the confused residents on ebay's address. These problems have seriously affected the reputation of many businesses on ebay and on ebay, making it hard for many customers to buy even if they feel the price of a commodity on ebay is chea
