1. The definition word is determined based on the characteristics of the processor.First, arm is a 32-bit processor, so its word is 32-bit. A half word is naturally 16bit;Bytes are 8bit regardless of the CPU.If on MSP430, because it is a 16-bit processor, its word is 16-bit. Half word = byte = 8bit.
2.One word: How many machines are exactly the number of digits, 32-bit machines -- 32-bit, 16-bit machines -- 16-bit (the CPU processes the data processi

In view of the current situation of GPS system for U.S. military control, the UAV status monitoring system based on "Beidou" Satellite navigation system and wireless digital radio station, which has the ability of regional navigation and positioning in China, is studied. The system takes the MSP430 series processor as the control unit, uses the UM220 "Beidou" navigation receiver to obtain the status information of the UAV, transmits the airborne infor
technologies will further advance wins's larger-scale applications.The TELOSB full name is Rev. Crossbow (KOESBO) Company Telos series node. B. In a wireless sensor network, each entity element is called a sensor node. TELOSB is one of the nodes. As shown in the image on the right, the node size is about the U disk size, above the circuit board, below the battery slot. The specific parameters are as follows:TELOSB

Whether it is MIPS, Nios II, Microblaze, MSP430, 8051, OpenRISC, OpenSPARC, leon2/leon3, etc. soft core processor, When implemented on an FPGA, we typically need a portion of the on-chip RAM storage bootloader, which can be used with GCC objcopy to bootloader text, exception vector, rodata, data or BSS and so on you need to copy out, you can generate binary files through-o binary, you can use-J.

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 microcomputer, the principle of single-chip mi
Someone has asked this question:"With the serial port interrupt reception is better understood, as long as the receiving cache receives the data, the flag bit will be placed, and then enter the interrupt service program to read the data in the receiving cache, but in the sending, should be sent after the data sent out after the flag bit will be set (I am the msp430 microcontroller), So what's the point of breaking into an interrupt when the data is se

What is DMP? DMP refers to the MPU-6050 integrated internal processor, the direct output of four yuan, can reduce the workload of peripheral microprocessors, and avoid the cumbersome filtering and data fusion, DMP official Drive library, is based on MSP430, used to drive DMP. Theoretically, it can be ported seamlessly into the STM32F103 series and STM32F4 series. However, if you are unwilling to transplant yourself, you can draw on the four-axis DMP l
It is not that easy to produce accessories that match the base connector of iOS devices: you need some parts provided by Apple, and you need to spend a lot of money to buy Apple's "made"IPhone license. However, you can use the headphone jack as the entry point for two-way data communication with the iPhone, and use the power of the iPhone to drive small circuit boards.

A program is a sequential sequence of instructions written to allow a computer to perform a task.C language is characterized by: structured, concise language, powerful, good transplant.Because of good transplant, so the majority of single-chip microcomputer such as 51, stm32,msp430, and many other embedded microprocessors are suitable for C language as a development language.The development process of C language is as follows:By: If the program compil
