Hi,
Is it possible to drive the PCF8575 pin as output LOW or HIGH.
I have schematic like below I want to control the charge enable and disable function.
> i2cset 0 0x24 0x80 0x00 // command to configure as output
How to drive this output high? The moment i execute above command I get high pulse then back to zero(may be because of 1K pulldown resistor). I want to drive this port pin as output high or low based on application. Default power up state of IO should be zero to keep my battery charger in charging mode when system load(lcd + processor + digital section) in off.
Rgds
