CORTEX-M3 has universal register R0-R15 and some special function registers. R0-r12 is the most "common purpose", the vast majority of 16-bit instructions can only use R0-R7, while the 32-bit Thumb-2 instruction has access to all the universal registers. Special function registers must be accessed through a dedicated instruction.Universal Purpose Register R0-R7R0-R7 is called a low group register. All instructions are accessible, R8-r12 called High gr

At present, the most common embedded operating system on the CORTEX-M3 platform is ucosii, in addition to support the mainstream embedded operating system is difficult to see, this is because CORTEX-M3 frequency is low (common 72M), does not support MMU, In-chip flash and in-chip ram are relatively small and so on, these limitations, such as wince system, embedded Linux, such as the need for MMU support sys

First, background:Recently, a project has been taken over, the core chip is both the LPC17XX series MCU, core arm of the COTEX-M3 core.If you want to play with an MCU, you have to take care of its clock!The clock is to the MCU, like the human heart. It gives the AHB, APB Bus The blood (clock frequency), and the devices that hang on the AHB (Advance High bus) bus are like our various organs, the peripherals that hang on the APB (Adance peripheral bus)

Comparison of CORTEX-M3 and ARM7In March 2005, ARM announced the latest ARMV7 architecture and defined three major series:the "A" series is designed for cutting-edge virtual memory-based operating systems and user applications. Mainly for the growing running of consumer electronics and wireless products including Linux, Windows CE and Symbian;The "R" series is for real-time systems. Mainly for systems that need to run real-time operating systems for c

In the next line of the first function systeminit (), there will be another common function.Nvic_prioritygroupconfig (nvic_prioritygroup_x)(X indicates numbers 1, 2, 3 ...). This function is related to the interrupt configuration. It configures the interrupt priority, including the preemption priority and subpriority.

The underlying application of Ti cortex m3 serial port to Ethernet routine is LWIP and the version is v1.3.2. For LWIP, a stranger can check it online. It is an open-source TCP/IP protocol written by Adam in Switzerland. Since the serial port to Ethernet routine is based on LWIP, let's see how LWIP is transplanted to TI's cortex m3 hardware. This is the split line ------- For the porting overview, refer to

Dual Stack mechanism of Cortex-M3 The CM3 stack is divided into two types: the master stack and the process stack. So, under what circumstances are these two stacks used? At this time, let's take a look at the CONTROL register (CONTROL) of CM3: the CONTROL register is used to define the privileged level and to select the stack pointer currently used. CONTROL [1] In handler mode of Cortex-M3, CONTROL

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

the following figure. The CPU is in thread state, working with the PSP stack, and the PSP points to the TASK1 stack. Each register in the CPU is the register value of the Task1 current task. The TASK2 is in a suspended state, and the TASK2 stack pointer is saved by the TCB2 SP variable. At the bottom of the Task2 stack, two pieces of data are saved, part of the register variable (including XPSR,PC,LR,R12,R0~R3) that is automatically saved to the stack when the CPU breaks, and the other is Ucos
