In this tutorial, we will study the programming method of MSP430 MCU Gpio. This article also applies to the MSP430X2XX devices used on the Launchpad Development Board, such as msp430g2553, msp430g2231, etc. Most pins on the MSP430 microcontroller are grouped into up to 8 ports, P1 to P8. Each port is 8-bit wide and has 8 related I/O pins. These pins are mapped directly to the appropriate port registers, so

The recent Android project encountered a memory-crushing problem, by analyzing the log to find the memory is trampled on the address, but can not find who stepped down. Generally the problem of stepping on memory, you can use the hardware data breakpoints to find the perpetrators. But in this project, stepping on the memory is in the Android boot process occurs, too late on Jtag, the other is the RAM is dynamically allocated, each boot is different (b

I have been studying and using MSP430 for a few months. I even saw a note on the micro-control forum, which is well recorded. Now I have reposted it to my blog for memo. Preliminary hardwareI am only learning about the 16-bit ultra-Power Single-Chip MSP430 produced by TI. I hope to learn from other friends. If not, please advise me more.Next, we will start our 430 journey.There are also a lot of books to ex

Direct Memory Access (dmadirect Memory Access) uses hardware to directly transmit high-speed data between memory and memory or between memory and I \ O devices without CPU intervention. This method is usually used to transmit data blocks. The msp430f16x series single-chip microcomputer contains a DMA module, and almost all internal Peripherals can trigger DMA to start data access. This module is implemented hereProgramCommon function libraries for ease of use. Hardware introduction:

Timers are commonly used by single-chip microcomputer. They are used to generate precise timing or other functions. MSP430 timers can not only complete precise timing, but also generate PWM waveform output, and capture time value (when the rising or falling edge arrives ). A general PWM waveform is generated here.Program. Hardware introduction: The timera of MSP430 Series Single-Chip Microcomputer

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

Recently, we are working on a project using the lpc1765,ProgramIt consists of two parts: bootloader, which completes the system configuration, and the work app, which runs when the system configuration is complete or no configuration is required to control the related logic. When JTAG is configured, erase sector is not checked, which leads to a successful download, but an error occurred in online debugging. The error description is as follows: Conte

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

At the beginning of September, I received an email from Ti about the promotion of the MSP430 Launchpad Development Board. I couldn't help but hook up with my students to apply for a free Ti sample, and join the group to sign up for the memories of the c2000 and MCU Innovation Design Competition (just a soy sauce ......), go to Texas Instruments online technical supportCommunityThe Forum circled. Surprise found Ti is holding a "easy Show,

, 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

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
