How to upgrade the MSP430 Program Key Laboratory of optoelectronics, Ocean University of China Abstract: This paper introduces how to upgrade the program of the MSP430 Series single-chip microcomputer, and describes in detail how to implement custom firmware upgrade and remote program upgrade. Various strategies and technologies required for firmware upgrade are provided. Keywords:

Generally, flash memory in single chip microcomputer is used for storage.ProgramCodeIs a read-only memory. In the MSP430 microcontroller, you can use the built-in flash controller to erase or rewrite any segment of content. In addition, the MSP430 microcontroller also has a flash area (information memory) for storing d

setting the baud rate, you must first select the appropriate clock source: The usart module can set the clock source uclk pin, aclk, smclk; for lower baud rate (less than 9600 ), the optional aclk is used as the clock source. In lpm3 (Low Power 3) mode, the serial port can still send and receive data normally. In addition, because the serial port receiving process has a three-to-two Decision logic, this requires at least three clock cycles, so the frequency division coefficient must be greater

Recently, I accidentally saw a netizen say that the MSP430 also has the GCC compiler, namely, MSPGCC. I also began to think that it is not far from developing the MSP430 in Linux. Google end time, find the MSPGCC Wiki: http://sourceforge.net/apps/mediawiki/mspgcc/index.php? Title = MSPGCC_Wiki, and a compiled installation package already exists under Ubuntu. Here, I don't really like Recently, I accidentall

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 di

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

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 p

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 i

We learn MCS51 single-chip microcomputer and AVR MCU, or PIC microcontroller, or MSP430 MCU, whether it feels that he can become an engineer? I'm here to say what I think.We learn these single-chip computer, the first study of theoretical knowledge, this is generally the theoretical knowledge of books, such as the introduction of the development of single-chip microcomputer, the application of single-chip m

Keys are one of the most commonly used input devices in the single-chip microcomputer system. A keyboard is required for interactive input. This blog implements a general keyboardProgramAs long as a function is provided to read the key value (the underlying key value), the program will complete some column processing, such as dejittering and saving to the queue. At the same time, this program provides the most commonly used 4*4 matrix keyboard program, and 4 button program. Hardware intr

LCD is one of the most commonly used display devices in single chip microcomputer systems.ProgramThe database is tested on the msp430f169 and msp1430f149 single-chip microcomputer and can be used with confidence. LCD uses the 12864 liquid crystal of the ocmj4x8c model and the control liquid crystal uses the parallel method, the three control ports are p3.0, p3.1, and p3.2, and the data uses the P5 data IO port.

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
