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

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

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 dif

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

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 f

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

MSP430 microcontroller adconverter 20:14:05 | classification: MSP430 microcontroller | report | font size subscription I. Brief Introduction: The adc12 module consists of the following parts: the input 16 analog switches (eight external channels, four internal channels), the ADC internal voltage reference source, the adc12 kernel, and the ADC clock source, collection and holding/trigger source, ADC data out

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

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

Only in this way can scanf be used to input data, in this case, when the input data is incorrect, you can modify the backspace and press a backspace key.

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
