Webb23 jan. 2024 · I2C Bus Locked Condition. The bus lock condition occurs when the allowed timeout period has been exceeded. In summary: transmitting an I2C packet is in progress, and the timing from when the last event was executed or received on the bus exceeds the allowed “wait” time. This wait time occurs when the SCL (serial clock) line of the bus … Webb11 okt. 2024 · Look closer: SDA is low.. This is the "arbitration lost" case, where the master wants to put a "1" on the bus but reads back a zero. In I²C terms, this would mean there is another master on the bus, an thus the original master ceases toggeling the SCL line.. Now you will have to look at why the ADC (or something else in on your I²C bus) exibits …
