Hello,

I have a question how do we work with this I2C to SPI bridge. We have the board I understand the hardware connections.

The hardware we have has only I2C interface with the following SPI bridge.

I am looking for python script that can send read and write commands to the device connected to this SPI bridge.

There is RTD to digital MAX31865 on the board connected to the SPI bridge.

Any idea how can I find the python scrip to read the temperature data from the microcontroller with I2C lines to the board.

 

Check out the Rasdpberry Pi forum, there may be some thing there.

 

There is no official Python library from NXP for the SC18IS606. You can use smbus or smbus2 python libraries.
