-chip microcomputer outputs high and low levels by the I/O port P1.6 at intervals, controls the D1 to emit infrared rays and stops the emission to detect smoke. Sensors work intermittently to reduce power consumption. The power supply of the integrated op amp is provided by the MCU P1.5. Similarly, only when the sensor is working, the op-amp scales up the received signal to avoid continuous operation to reduce power consumption. After the signal is am

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

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

Overview I think this is meaningless. The biggest feature of an embedded system is "embedding". That is to say, your control system is embedded in your control object, so the first thing is to obey the needs and features of objects. What is the basis for separation from object null? Each MCU has its own value, and each user's choice has its own rationale. Starting from aVR, It is a selling point of a single clock period command, compared with the cla

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 com

Contact SCM has a few years of time, has been focused on how to write some applications on a single chip microcomputer, how to start the knowledge of little, ashamed ashamed ... Today, I have to tidy up a bit, deepen the understanding of the SCM, such as why the definition of the data area of the variable restart the initial value of 0. When the MCU is powered on, it will execute startup. The instructions for the A51 file, I analyzed the instructions

First, the chip is divided into chip-level and system-level Chip level is, just a chip, such as 51 single-chip microcomputer, you can write a program, download and follow the program to run, before and after the program System level is, can run operating system, such as ARM,SOC, have RAM and ROM Cpu: Computers should understand that the central processing Unit, computer computing core and control core, all of the following chips contain CPU, chip-level MPU: microprocessor, including CPU on

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 data that needs to be permanently stored after power loss. The Flash Controller of 430 can

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 f

The ad7708 is a 16-bit Σ-△type adconverter chip. in low-frequency applications, the ad7708 can be used as the complete front end of a single power supply. The ad7708 contains a PGA (Programmable Gain Amplifier) to enlarge the signal. The PGA range is 20-28, which is programmable, when the reference voltage is V, the voltage from 20mv to 2.56v can be measured. The ad7708 and ad7718 pin functions exactly the same, but the number of digits ad7718 is 24 bits. If you use 7718, you only need to change

The msp430f149 supports serial asynchronous and synchronous communication, each with a separate frame format and independent control registers.Usart Asynchronous communicationThe

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:

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
