SC18IS606 - how to read and write in Python

[johnpeter]

Hello, 

We are using SC18IS606 to read PT1000 temperature sensor through MAX31865 having SPI interface. We need to connect SC18IS606 to I2C master MCP2221. Do we have Python libraries for SC18IS606 and Python example how to read and write to SC18IS606 ?

Hello,

We do not provide an official Python library specifically for SC18IS606, but the device uses a very simple command‑based protocol, so it is pretty straightforward to access using any standard Python I²C package.

To understand how to send commands to the SC18IS606, I recommend to look at:

Chapter 8 – “I²C‑bus to SPI communications example” in the SC18IS606 datasheet which shows complete I²C command sequences for SPI reads/writes.

UM11666 – SC18IS606-EVB board examples (section 4.4) contains sequences for configuring SPI, reading device ID, EEPROM read/write etc.

BRs, Tomas
