msp430 microcontroller

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

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

Please note that idloc (x) contains a maximum of two hexadecimal bytes. the excess part will be invalid. For example, if you write 987fe3, E3 will be lost. In addition, let's talk about how the two hexadecimal numbers are stored in the ID area. We already know that idloc (x) can cont

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,

Ucos-ii on MSP430 Migration 2--detailed process 1, a new IAR project file, saved in the "E:\430uCOSII\OSTest" folder. Create a new folder SRC, which is used to store the source code. As shown in the following figure. 2, add the source code corresponding folder. (1) Create a new two folders under the SRC folder, "Oskernel" and "Msp430ports" respectively. (2) Decompression micrium-ucos-ii-v286.zip. There are 14 files under Micrium\software\ucos-ii\sou

Microcontroller Remote Control stepper motor, LED lights and buzzer The stepping motor module, LED lamp and buzzer module of the single-chip microcomputer are controlled by the C # language to enable the stepping motor to perform forward, reverse, and stop and control the speed; the LED lamp module performs selective breathing expression; the start and end of the buzzer module. The host computer controls the stepper motor, LED lamp, and buzzer module

First, prefaceFinally completed the Windows universal application "51 microcontroller assembly", six months ago began to play WindowsPhone development of the first real meaning of the app (also many shortcomings =_=). Development from mid-January to the end of the test to today, during the internship for half a month, play a few days, calculate the basic get 3 weeks. Not much to say, summary summary.Second, the development of data preparationThe main

access is different. Idata is accessed in a pointer-like manner in C. The statements in the assembly are: Mox ACC, @Rx. (Unimportant supplement: C-Idata do a good job of pointer-type access)XData: External extended RAM, generally referred to as external 0x0000-0xffff space, accessed with dptr.pdata: Low 256 bytes of external extended RAM, address reads and writes on A0-A7, with Movx ACC, @Rx Read and write. This is more special, and C51 seems to have a bug, it is recommended to use less. But al

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

few microcontrollers include a DAC. Although you can easily find a inexpensive DAC to control from your microcontroller, you can use, unused peripherals inste Ad of adding parts. Fortunately, you can convert a microcontroller ' s ADC channel along with a GPIO (general-purpose input/output) pin to a D AC. You can make a DAC by charging a capacitor to an analog level by driving it high. You can also discharge

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

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 function implements the delay of __cycles CPU cycles, but for the setting of this parameter
