WebbIf the data line (SDA) is stuck LOW, the master should send nine clock pulses. The device that held the bus LOW should release it sometime within those nine clocks. If not, then use the HW reset or cycle power to clear the bus. The master I2C must be able to generate this “bus clear” sequence.

The problem was that the resistors I was using as pull-up resistors were in fact 1k not 2k. I changed them for 2k resistors and the problem disappeared.

Webb4 aug. 2024 · If you read the I2C specification thoroughly, you'll notice that the SDA hold time refers to the falling SCL edge. An essential rule is that SDA must be stable during SCL high state. From the pic of Andre_teprom it can be seen that the data is changing during the SCL high time. - - - Updated - - - andre_teprom said: WebbFör 1 dag sedan · Hold time on the other hand is defined as the time interval after sampling has been initiated.

Webb19 nov. 2024 · SDA must be stable for the entire HIGH period of SCL. SDA must be held for 300ns while SCL goes low. Saying "while" here seems a bit strange, but it's to emphasize the 0 + 300ns minimum needed for SCL transition back to low. Typically I believe the hold time will be (1/2*SCL period) + 300ns. Webb4 mars 2024 · tHD;STA hold time (repeated) START condition: Minimum time the data should be low before SCL is in low state at (repeated) START condition. It is measured as time taken from 30% of the amplitude of SDA at high to low transition to 70% of the amplitude at high to low transition of SCL Signal.

WebbThe I2C bus consists of two lines: serial data line (SDA) and serial clock (SCL). Both lines require pull-up resistors.
