Expand description
I2C error kind.
This represents a common set of I2C operation errors. HAL implementations are free to define more specific or additional error types. However, by providing a mapping to these common I2C errors, generic code can still react to them.
Variants (Non-exhaustive)§
This enum is marked as non-exhaustive
Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.
Bus
Bus error occurred. e.g. A START or a STOP condition is detected and is not located after a multiple of 9 SCL clock pulses.
ArbitrationLoss
The arbitration was lost, e.g. electrical problems with the clock signal.
NoAcknowledge(NoAcknowledgeSource)
A bus operation was not acknowledged, e.g. due to the addressed device not being available on the bus or the device not being ready to process requests at the moment.
Overrun
The peripheral receive buffer was overrun.
Other
A different error occurred. The original error may contain more information.
