I2C (i-square-c) is an acronym for “Inter-Integrated-Circuit” which was originally created by Philips Semiconductors (now NXP) back in 1982. The I2C is a multi-master, multi-slave, synchronous, bidirectional,
Begin a transmission to the I2C slave device with the given address. Subsequently, queue bytes for transmission with thewrite()function and transmit them by callingendTransmission(). Parameters address: the 7-bit address of the device to transmit to Returns None Wire.endTransmission()主机向从机传...
byte : the number of bytes returned from the slave device Wire.beginTransmission(address) 主机向从机传送数据开始 Description Begin a transmission to the I2C slave device with the given address. Subsequently, queue bytes for transmission with the write() function and transmit them by calling endTra...
In this tutorial we will learn how the I2C communication protocol works, as well as, make a practical example of Arduino I2C communication with...
I2C bus Interface Spectral responsibility is approximately human eye response Illuminance to digital converter Range: 1 – 65535 lux Low current by power down function 50Hz / 60Hz Light noise reject-function It is possible to select 2 different I2 C slave-addresses ...
slave through a serial data (SDA) line. The transmission speed can be up to 3.4 Mbps. All devices that want to transfer data via I2C should have a unique address and can operate as either transmitter or receiver depending on the function of the device. For example an OLED display module ...
A software IIC/I2C library aimed at the arduino/atmega platform. Master and multi-slave supported. SoftIIC is a class which enables easy communication to other IIC devices, as a master or slave, or in the presence of other masters. Master mode features: With a 16MHz core clock, 100KHz ...
I notice that the configBlock gets written to the chip every time you want to take a measurement (in the function startMeasurement). The configBlock's first byte is the device address. Is there a nice way to change the device's address t...
@param addr I2C address of corresponding SSD1306 display (or pass 0 to use default of 0x3C for 128x32 display, 0x3D for all others). SPI displays (hardware or software) do not use addresses, but this argument is still required (pass 0 or any value really, it will simply be ignored)...
