integrated environment and infrared to digital converter with a built-in infrared LED driver and I2C interface (compatible with SMBus ). The device provides ambient light sensing to achieve stable backlight/display brightness control. Infrared sensing with interrupt function can achieve close estimation. (Proximity sensing is an important feature. More details will be discussed below) For ambient light sen

. Similarly, the "set" in the open set circuit refers to the collector of the transistor. An on-line leakage circuit refers to a circuit with extremely high output of the MOs. In general, the pull-up resistance is added to the circuit with an external leakage pole. The complete open-leakage circuit should be composed of an Open-leakage device and an open-leakage pull-up resistor. 1: Circuit components have the following characteristics:1. Use the drive capability of the external circuit to re

Article Title: Use lm_sensors to view the motherboard and CPU temperature. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. In Linux, you can use the lm_sensors software to view the temperature of the motherboard and CPU, which is very convenient. You can find lm_sensors in yum and install it: [Leconte @ web ~] $ Yum search sensors Loaded plugins: fastestmirro

The I²c (intel-integrated circuit) bus is a two-wire serial bus developed by Phliphs Corporation to connect peripherals and microcontrollers. The application is very extensive, can use in the connection E2rom to save the various interface card, the monitor ROM information, may also use in the BMC to connect various temperature, the voltage, the current and so on the sensor, may also use to connect the memory stripe DIMM, uses to obtain the memory bar the information.

).The library functions are used to transmit and receive data between the two i²c analog devices using STM32 and to view data exchange through the serial port. Direct Operation Register First need to configure the I²c interface clock, the relevant registers are as follows: I2C_CR2 register low five-bit: NBSP;NBSP;NBSP;NBSP;FREQ[5:0]:I2C module clock frequency, The correct input clock frequency must be set to produce the correct timing, allowing the

1. StartI want to drive the OLED screen on the lychee pie, but the write driver in the kernel is definitely a hassle for me, so I'm going to go back to the second, I want to operate the generic I²c interface in the application layer to implement the OLED driver.I bought the OLED is the classic model, four-pin IIC interface OLED. First I refer to Nanopi's Matrix Library, referring to his IIC application layer function. I found out he included a i2c-dev

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
