i2c oscilloscope

Use MRTG to monitor CPU temperature-Linux Enterprise Application-Linux server application information. The following is a detailed description. It's time to roll again in summer ~ I believe many people are concerned about whether their CPU will go on strike due to overheating? Is there any software under Linux that can monitor the temperature? That is lm-sensor. How can I install it? If your core version is 2.2.X Download the i2c and lm-sensor kits.

Article Summary: At present, the major motherboard vendors use overclocking software is based on the frequency generator This hardware implementation, and most of the frequency generator is a I2C bus equipment, this article introduces the basic principles of I2C equipment and overclocking the fundamental methods and principles. Key words: I2C, frequency generat

that FT5X06 can work in both the SPI interface mode and I2C interface mode, whether working in SPI or I2C, in terms of the hardware interface design, the following control ports need to be connected. As shown in: 1): The INT pin, which is a mid-range signal. It is used to notify the HOST terminal that FT5X06 is ready for reading. 2): WAKE pin: this function is mainly used to convert FT5X06 from sleep to w

Abstract:A high-resolution digital camera based on USB2.0 protocol is introduced. The basic hardware circuit and software design method of high-resolution digital camera are presented by using CMOS image sensor ob9620 and USB controller CY7C68013. Keywords: USB2.0; I2C; camera; ov9620 1 Overview Currently, both bus interfaces (USB and IEEE 1394 interfaces) that can transmit high-quality video signals support plug-and-play, and are easy to expand and
