The most recent time is the I2C of stm32. I know that the I2C of stm32 is not easy to use, because I have used analog I2C, and I have also written the AVR I2C, that is, the
compared the linux directory before and after the power plugging, but there was no clue when I looked for it for a long time. Why did I check CPU and memory for commands, check the power supply and there will be no command? Later, I found that this may not exist!
I don't know the driver, I don't know the hardware, and I can't use the scripts written by others. I try to understand it. The following is your understanding. Please refer to Hai Han for errors.
The first thing we can understand is th

As the first part of the oscilloscope structure (red box on the left)The actual output waveform corresponding to the selection of three coupling modes is posted below2, so

The above is the address of the register that needs to write ov9650 sequentially and the written value (transmitted using I2C subsystem)
The I2C subsystem transmission has been analyzed. The platform device resources can be initialized in the Bo
equipment. The basic idea is to implement a parent device for the public part of these functions, in order to share certain system resources and functions, then each child function is implemented as its sub device, so that both resources and code are shared, and a reasonable device hierarchy can be achieved, the main use of the API is: Mfd_add_devices (), Mfd_remove_devices (), mfd_cell_enable (), mfd_cell_disable (), Mfd_clone_cell ().

a series of digital signals accumulated on the oscilloscope , the shape of the image is similar to the eye, it is called eye diagram.When using the afterglow oscilloscope to observe the transmitted data signal, the time signal of the measured system is used to control the scanning of the oscilloscope by external triggering or external synchronization, because th

However, through reverse tracing, the tester clearly sees the test case table affected by the changed code, and through the cumulative coverage technology, this greatly shortens the regression testing time.

built-in metering table was a very good tool, however, when you make movies and TV series that are relatively cautious about program production, the reflection metering table may cause a deviation in the exposure volume. Although Sony's camera has improved, there are different types of sensitive parts in the digital camera, allowing users to select. Users can select a small block in the center of the screen, which can be the lower half, the upper half or the whole screen for measurement and pro

1 Overview
This task is to debug the touch screen driver on the flykar I. mx 6 quqd sabrelite Development Board. The touch screen chip is goodix's gt828 chip and the touch screen interface is I2C.
Operating System: Android 4.0.4
Kernel version: 3.0.15
2 debugging steps 2.1 hardware connection 2.1.1 development board hardware interface
The Development Board has provided independent interfaces for touch screen, which are as follows:
It provides a set
Processing Program and determines that the event type is a data sending event based on the bo Bit, it calls the GPIB data sending program and sends the remaining data in the buffer zone to the GPIB bus in sequence.
3. Running status and Result
The design of the RS232-1 GUI controller in this article has been successfully used in the connection between the computer and the tds210 oscilloscope. Figure 6 shows the display interface of the Computer Super
Write a program, use the I2C interface of S3C2410 to read/write the serial EEPROM 24lc04 (I2C interface), write a set of data, read and display it, and check whether it is correct.
Analysis: the I2C of S3C2410 is the master device, and the I2C of EEPROM is the slave device. The operations are written and read by the m
