msp430 i2c

Clock stretching (stretching)Clock stretching pauses a transmission by pulling the SCL line down. The transfer continues until the SCL line is released high. Clock stretching is optional, in fact most slave devices do not include the SCL driver, so

[Tutorial] Linux I2C device driver-Linux general technology-Linux programming and kernel information. The following is a detailed description. My ARM platform is Cortex A9. The MSP430 microcontroller communicates with the ARM-core I2C bus. the ARM runs on a Linux system and the Linux kernel has an I2C bus driver. Ther

I. About I2C The I2C (Inter-Integrated Circuit) bus is a two-line serial bus developed by Philips to connect the microcontroller and its peripheral devices. The main advantage of I2C bus is its simplicity and effectiveness. The simplicity is embodied in the simple wiring. There are only two lines of data cable (SCL) and clock line (SDA), and the control is simpl

I installed the TinyOS in the 64-bit version of Ubuntu 12.04LTS, but the final compilation was successful, but all the Java tools were not available. This time I re-installed a 32-bit Ubuntu system. This is sure to be installed.But I found an error after I finished installing all the tutorials.When make TELOSB,> mkdir-p BUILD/TELOSB > Compiling BLINKAPPC to a TELOSB binary > Ncc-o build/telosb/main.exe-os-o-mdisable- hwmul-fnesc-separator=__ >-wall-wshadow-wnesc-all-target=telosb-fnesc-cfile=bui

For beginners who want to learn MSP430 MCU, or, you are just transferred to the electronic hardware embedded development, if your electronic basic course has been completed, want to master MSP430 microcontroller, and how to break into the MSP430 learning process as soon as possible, Now summarizes some problems that the novice starts to learn

consists of two parts: platform_device and platfrom_driver. The general process for developing the underlying driver through the platform mechanism is: Define platform_device-> Register platform_device-> define platform_driver-> Register platform_driver. The first thing to confirm is the device resource information, such as the device address and interrupt number. In the 2.6 kernel, the platform device is described by the structure platform_device, which is defined in kernel \ include \ Li

Register platform_driver.The first thing to confirm is the device resource information, such as the device address and interrupt number.In the 2.6 kernel, the platform device is described by the structure platform_device, which is defined in kernel/include/Linux/platform_device.h,Struct platform_device {Const char * Name;U32 ID;Struct device dev;U32 num_resources;Struct resource * resource;};An important element of this structure is resource, w

Brief The next content will be the basic functions of MPU9250 detailed introduction, mainly divided into modules for elaboration. Clock MPU9250 has two internal clock sources, as well as a PLL.Internal clock Source: Clock Source Description Internal oscillator Low power consumption, but slightly worse clock accuracy X,y or Z-direction gyro MEMS clock, high power consumption, but clock accuracy (as long as the gyro is enabled, it will use the

　Bus driver4.1 OverviewThe I²C bus driver is the software implementation of the I²C adapter, which provides the ability of the I²C adapter to complete data communication from the device, such as start, stop, response signal and master_xfer implementation function.The I²C bus driver is described by I2c_adapter and I2c_algorithm.Hardware description of the 4.2 S3C2440I2C controllerThe s3c2440 processor incorporates an I²C controller with four registers for control:Iiccon i²c Control RegisterIicsta
