Hello,
I have been dealing with a PCA9665 controller for i2c. During
interactions with some hardware, it is common for the bus to get into a
unusable state (in this case, SCL is pulled low by a slave). But, even
after disconnecting all the slaves, I am not able to get the bus working
again.
Reading the algo code, I see there are reset features for both chips
supported by the driver, so I wonder if there is some way or tool to
trigger this reset on request (that is, after I have disconnected all
the slaves).
