Demodulation Circuit In my design, the demodulation end uses the MSP430 single-chip microcomputer, because the power consumption of Ti series single-chip microcomputer is very low, in sleep state, the current can reach UA level, under normal operation, the current can also be kept at several Ma levels. Connect the right channel of the m

The diagram is as follows: From the diagram above, we can see that in Android, sensor is divided into four layers: Driver layer (sensor driver), Hardware Abstraction Layer (native), middle layer (framework), and application layer (Java ). The hardware abstraction layer and the intermediate layer can be combi

This article from http://blog.csdn.net/hellogv/, reference must indicate the source! I recently want to develop on the MSP430, and I/O simulation on the first hand will be difficult. Fortunately, there are already many examples of the implementation of the soft serial port of the MSP430 on the Internet. Most of the Code in this article is referred> Logging .... It took a week to debug the I/O simulation UAR

Steps:(1) first, mem3280 is an I2C device, so the first step is to check the chip spec and determine its I2C address (0x30)(2) After the address is determined, add I2C device information in the kernel/ARCH/ARM/mach-vc0882/board-vortex.c file:1212 static struct i2c_board_info i2c_devs1 [] = {1213 # ifdef config_sensor_ssz03041214 {i2c_board_info ("ssz0304-sensor",

. Under the shift pulse of the main device, the data is transmitted by bit, with the highest position in front and the lowest position in the back, full Duplex Communication.If you use a general IO port to simulate the SPI bus, you must have an output port (SDO), one input port (SDI), and the other port depends on the type of the implemented device, if you want to implement a Master/Slave Device, You need to input the output port. If you want to implement only the master device, you need to outp

Summary of debugging process and method of camera driver Based on the previous debugging of the camera driver, I have summarized some minor experiences: 1. Check whether the camera circuit connection is correct based on the circuit diagram; 2. Use A multimeter to measure the power supply pin of camera and check whether the power supply of camera is normal.ProgramFor power control; 3. Check the spec document of camera and check whether the pin triggering of pwdn and reset is normal and whet

After understanding the datasheet, don't rush to write code, you should first do is to give you will write the driver design a framework. So what should the framework be based on? Concrete how to build it. General, from USB drive to I2C Drive, from SPI Drive to serial drive, from PCI driver to DMA driver, and so on, no matter what type of driver, it always has one or several basic fixed routines for you to choose from. If you're going to write a touch

Analyze this error. The error code indicates that when uboot is started, 6 bytes (MAC address) at 0x7f00 In the eeprom are read through i2c. After the failure, "EEPROM @ 0x50 read FAILED !!

In fact, some symbols have long been introduced in my logs. For details, see the second log "What do some symbols in the. Bat configuration file mean?". I did not learn it very well at that time. Today, my sister-in-law asked me to sort out a log to facilitate later students to learn. In fact, these files are all batch files. For specific commands, refer to Windows shell programming commands. The symbols in the title of the article are not common punctuation marks we often see. Do not think abou

relationship is formed by means of an up-pull resistor without adding any device. This is also the principle that I2C, SMBus, and other bus determine the bus occupation status. Supplement: What is "line and "? : On a single node (line), connect an upstream resistor to the Collector C or drain D of the power supply VCC or VDD and N or NMOS transistors, the emission pole E or source Pole s of these transistors are connected to the ground line.
