msp430 uart

The serial communication interface is one of the most common methods for data communication between a processor and other devices. MyProgramThe library is for the msp430f14 series and msp430f16 series. I usually use the single-chip microcomputer: msp430f149 and msp430f169. Both single-chip microcomputer have two Enhanced serial communication interfaces, both of which can be synchronous or asynchronous communication. Even the 169 module usart0 can perform I2C communication. Here, we will only dis

MSP430Modulus conversion module-adc12The adc12 module of MSP430 is a 12-bit precision A/D conversion module, which features high speed and versatility. Most of them have built-in ADC modules, while some films without ADC modules can also achieve AD conversion by using the built-in analog comparator. In the product series, we can simply understand their ADC functions through the following list.Series of ADC functions to achieve conversion AccuracyMsp43

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

Reset UART has two methods: UART reset. Write 0 to the UART reset bit (urst) of the power and emulation control register, urpecr. This operation resets the UART state machine without affecting the UART registers. DSP reset. Reduce the reset # pin of the DSP. The entire

I had some problems when I studied Nios's UART and did some sharing.Nios II You can use the round-the-clock method to read information in two ways.Pre-Test:1. Add a UART to the Qsys and add the new UART Rx, TX pair in the Quartus.Question one: Use the round-of-the-way reader programWhen I use the following code to go to the wheel, it is time to wait until the 62n

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

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:

, 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 so

Optimization Design of smoke alarm based on MSP430 [Date: 2008-10-22] Source: World Electronic Components by Li Peng Wang Ting Wu yanwen, Huazhong Normal University [Font:Large Medium Small] 　 Introduction Traditional smoke alarms are generally composed of Smoke sensors and smoke detection chips. The detection chips receive and process sensor signals to determine whether a fire has occurred. This smoke detector has simple structu

This article from http://blog.csdn.net/hellogv/, reference must indicate the source! I recently want to develop on the MSP430, and I/O simulation on the first hand will be difficult. Fortunately, there are already many examples of the implementation of the soft serial port of the MSP430 on the Internet. Most of the Code in this article is referred> Logging .... It took a week to debug the I/O simulation

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

when we use the MSP430 MCU for project development, we will encounter the output format of the two image files (as shown): Legacy COFF and Eabi (ELF), this article launches from this topic, leads to COFF Abi and Eabi two application binary interface, Enables developers to low-level from theMSP430 has a new understanding. 1. image file output formatthe MSP430 compiler can output image files in two formats:A

for AVR and arm, I decided to study it well. Here, I will give an advertisement for GCC by the way, we can also see that the best way to use the C language is to directly use the English language. The GCC compiler is obviously the best choice.Arm vs MSP430 The MSP430 will be dedicated, low-voltage, and low-power. More models should appear for measurement in different scenarios. The 430 programming method

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
