Dear all: Pardon me, it is not well. 1.Use ARM U23 & I2C clock. 2.SGK is set. 3.Like topic:When power is on or the soft is run then How can i let the SCL or SDA set to high?
Thank you very much.
Like what topic? You haven't specified any topic. Your summary does not give a summary of your problem.
And your message doesn't contain a description of your problem.
You haven't even mentioned what processor you are using.
But if you do implement I2C - most ARM processors have sample code for I2C available somewhere out there on the net - then the processor will (if it supports I2C in hardware) handle the I2C signals.
Note that depending on processor, you may need to add external pull-up resistors.
So why did you choose C51 as your toolset/architecture?!
So why did you choose C51 as your toolset/architecture?! this is a recurring problem it would be nice if a change of 'Toolset' in a subsequent post would be reflected in the index.

It's not as simple as that; eg, this is a "Non-Specific (Generic)" comment...
