This article from http://blog.csdn.net/hellogv/, reference must indicate the source! Flash-type MSP430 single-chip has information memory segmenga and segmentb, segmenga and segmentb each have 128 characters, segmentb address is: 0x01000h to 0x0000f, Segmenta address is: 0x01080h to 0x010ffh. After the program is written to MSP430, the program can save power-off data through segmenga and segmentb. Note: seg

The program of the MSP430 microcontroller is sometimes prone to fly, resulting in abnormal operation. The common causes are as follows:The dog is not set to stop or be fed in time.The interrupt function is not defined, but the corresponding interrupt is enabled. When the interrupt occurs, the interrupt function entry cannot be found.The power supply voltage is unstable, or the input voltage of the I/O pin is too high, resulting in internal data interf

I found some questions when I read the header file ccw.x613x. h In rf_example_code_v1.0. First, let's take a look at ccw.x613x. h.Three # define examples in: # Define defc (name, address) _ no_init volatile unsigned char name @ address; # Define defw (name, address) _ no_init volatile unsigned short name @ address; # Define defcw (name, address) _ no_init Union { Struct { Volatile unsigned char name ##_ L; Volatile unsigned char name ##_ h; }; Volatile unsigned short name; } @ Address; The previ

Ucos-ii on MSP430 Migration 2--detailed process 1, a new IAR project file, saved in the "E:\430uCOSII\OSTest" folder. Create a new folder SRC, which is used to store the source code. As shown in the following figure. 2, add the source code corresponding folder. (1) Create a new two folders under the SRC folder, "Oskernel" and "Msp430ports" respectively. (2) Decompression micrium-ucos-ii-v286.zip. There are 14 files under Micrium\software\ucos-ii\sou

In a twinkling of an eye, my junior year is coming to an end, and my college life is coming to an end. Because I am interested in software, I may be away from my major (Electronic Information Science and Technology) after graduation; I also participated in electronic design competitions during my college career. During the competition, I was mainly responsible for Single-Chip MicrocomputerProgramTherefore, we are familiar with the MSP430 Series single

Here, let me discuss the problem of using __delay_cycles delay for MSP430 MCU.The IAR for MSP430 compiler provides a compiler inline precision delay function (not a truefunction) to provide the user with a precise delay, the function prototype is:__intrinsic void __delay_cycles (unsigned long __cycles);This intrinsic function implements the delay of __cycles CPU cycles, but for the setting of this parameter

, the information can be transmitted in two directions, but not at the same time two-way transmission is called single-duplex communication, the same two-way transmission is called full-duplex communication.Serial communication can be divided into synchronous communication and asynchronous communication two, asynchronous communication (UART) transceiver does not have the same clock source, and synchronous communication (SPI, I²C) has the same clock source.The USCI has a hardware module that supp

The IAP Upgrade Program tested and written over the past few days is really bad. It can be downloaded but cannot run. After a variety of tests, I finally found the cause of the problem. Now I will summarize the reasons when I write the IAP program. Problems and Solutions. First, we need to implement the IAP Upgrade Program for single-chip microcomputer. We need to know how our IDE can Fix the compilation address of the function or variable of the program, because we need to fix the address of

, the power supply. The original idea was very simple: USB power supply! It's easy, so I didn't hesitate to choose USB to provide the driver power for the system. But at the end of the project, there was no USB interface next to it, so can you still use it, as a result, we have learned that the project we are working on is always user-oriented, and the power supply must be done independently so that it can be called a system. 3. The next step is the software part. We should have no system cont

First, write the program according to the normal use of IAR, and then use IAR to compile and generate the TXT file. to generate such downloadable files, you need to set IAR as follows: Then compile the program to generate a TXT file. NOTE 1: The generated TXT file can be found in the \ debug \ exe directory of the project folder.NOTE 2: If you want to use JTAG fo

the MSP430 contains the adc12 module, which can complete 12-bit analog-to-digital conversion. When the requirements for precision or other indicators are not high, you can use the adc12 In the 430 microcontroller to complete the analog-to-digital conversion. Here we mainly implement a general adc12 module initialization Program . The specific data storage and processing needs to be added in the interrupt processing function. Hardware introduct

Exit the low-power mode as follows:Lpm0_exit; Exit low-Power mode 0 // too easy to have wood thereLpm4_exit; Exit Low Power Mode 4 (exceptLPM4.5 )Summarize the exper

Let's take a look at my wife's views:Icer, SOC design for arm CPUsLet me say a few words, hoping to say a little thinner.First of all, said CPU, central processing unit, the essence is an integrated circuit, the function is to read out from a place (such as ROM) a co

For detailed settings, refer to: MSP430 library In this way, the scanf port of the keyboard is completed. to use it, you only need to include the stdio. h file, and then initialize the keyboard. Example: Here, the example implements simple interaction between the keyboard and the LCD. When the keyboard inputs data, the LCD is displayed normally, just like the keyboard an
