Review Comment:
Hi @xiaoxiang781216,
In our case, this SSD1306 display is pulling power from the I2C lines
because the supply voltage of the display is not active yet.
This causes the I2C transactions to look OK, but in fact it is not being
configured correctly.
I've checked, but there is no way to read out this display if it went OK.
We thought of a better solution and opened an other PR, see closing comment.
