Thus, the SMBus has a minimum-clock-speed specification. By comparison, the I²C bus can go static indefinitely. In the I²C bus, either a master or a slave can hold the clock low as long as necessary to process data.

WebbAt first, when I hooked up the STM32 the Linux I2C bus would basically halt (timeout on every read). I hooked up the scope and found that the STM32 is pulling the clock line … Webb4 maj 2024 · If they are it is assumed there is an I2C device present at that address. While that is fine in theory, should work according to I2C specifications, I have found that in some cases it doesn't because not all I2C devices are as spec compliant as they should be. Some may end up waiting for write data even though they should have aborted that write. javascript programiz online

Webb9 feb. 2024 · I2C Protocol Working Principle. The working of the I2C communication protocol happens through open drain lines which are Serial Data (SDA) and SCL (Serial Clock). Initially, both the SDA and SCL lines are pulled high and the bus mainly functions in two modes which are Master and Slave. Message Format in I2C.
