hello,
I saw your lib have a shiftOut function. Is that possible use that function for controlling a 74HC595 ?
I means use a PCF8574 to control a 74HC595

we have
```
// looks like we support PCF8575 i2c I/O expander
m_i2c.read(/*address*/0x20, variant, sizeof(variant));
```
1) what is magic 0x20 where is it mentioned on https://www.ti.com/lit/…

I2CKeyPad version=0.4.0 and PCF8575 version=0.2.3 not working together.
On stm32f411 individually they work well but together on the same bus they conflict.
I change the I2C bus for pcf8575 (use I2…

Hi,
I'm trying to update a library which depends on this crate (ag-lcd) to embedded-hal 1.0.0.
It currently uses version 0.3.1 of port-expander, before the PortDriverTotemPole trait bound was intro…
