Using Different I2C Address - Raspberry Pi PiCoolFAN4 User Manual

PiCoolFAN4
Using Different I
As mentioned before the PiCoolFAN4 can be used with different addresses other than 0x60. This is
because some HATs are using different addresses and there is a possibility to have a conflict between
them and PiCoolFAN4.
The available addresses are the 0x30, 0x40, and 0x50.
All handling of the PiCoolFAN4 is identical, the only changes are needed are to bootload new firmware
addressed to selected new address.
Due to ultra-small memory footprint on the used micro controller (due to price reasons) in the
PiCoolFAN4, there is no space to implement I
of the PiCoolFAN4 firmware is released for all available address separately. When doing boot loading user
need to know that some functionalities (factory setup) cannot run as they are referred to different
addresses. Similar with Daemon and status monitoring python script. These programs are provided in a
single package together with firmware(s).
As using of the different addresses is advanced usage user need to be first familiar with the product before
start experimenting with different I
