This translator will only com-municate with CPUs that support PECI 1. A bus means specification for the connections, protocol, formats, addresses and procedures that define the rules on the bus. Leens, February 2009. 25°C over the sensor's -40°C to +125°C range and precision of +0. All I2C master and slave devices are connected with only those two wires. Using Feature Set of I2C Master on TM4C129x Microcontrollers AmitAshara ABSTRACT The inter-integrated circuit (I2C) is a multi-master, multi-slave, single-ended bus that is typically used for attaching lower speed peripheral ICs to processors and microcontrollers. This protocol is patented by NXP(formerly Phillips), to save licensing cost, Atmel using the word TWI(2-wire interface) which exactly same as I2C, so any AVR device will not have I2C but it will have TWI. I2C protocol Vcc, GND and variable end is connected to VEE can I2C stands for Inter-Integrated circuit is a be used to adjust contrast. I2C interface functionality can be realized via software programming, the clock frequency reaches 100 kHz at a maximum. It uses Power Relays to create this output. Fundamentally, there are just two: Start and Stop. Symbol Description EFM32G230F128G-E-QFN64Description: 32-bit ARM Cortex-M3 microcontroller, 128 kB flash, 16 kB x 8 RAM, Silicon Labs - Gecko, QFN-64Keys: MC. The functional simulation of the bus is also carried under different test cases. The logic levels are defined by the power supply +VCC of the devices connected to the bus and their technology; in our case the power supply is close to 3. To use the I2C protocol with an LCD display and Arduino, there is a special library to be downloaded and included in the code. PMBus™ Commands. Patel, Janakkumar; Gupta, Neeraj: Publication: International. The most used communication protocols are USART, IIC, SPI and CAN.
