I2c Bus clear when no acknowledgment

emerging — Thu, 14 Nov 2024 10:02:32 GMT

Hello Team,

As per our requirement when there is no acknowledgment from I2c slave we have to wait 1 sec and then call I2C bus clear command.

Could someone please assist with how to check the acknowledgment and how to clear the bus and what functions i can use for this.

It will be helpful if anyone can provide an example too.

Thanks and regards,

There is one thread discussing the NACK Detect Flag: S32K144 IIC communication question - NXP Community.

You can implement in application to check this flag and clear the bus. There is also an example at the end of the thread.

Best regards,
Julián
