Peripheral I2C[edit | edit source]
I2C is a two-wire, bidirectional serial bus that provides a simple, efficient method of data exchange, minimizing the interconnection between devices.
This bus is suitable for applications requiring occasional communications over a short distance between many devices.
Description[edit | edit source]
The I2C interface available on ETRA SoM is based on TSM32MP1 SoC.
The I2C port supports the following standards and features:
- slave and master modes
- multimaster capability
- standard-mode (up to 100 kHz), fast-mode (up to 400 kHz) and fast-mode Plus (up to 1 MHz)
- 7-bit and 10-bit addressing mode
- programmable setup and hold times
- 1-byte buffer with DMA capability
- programmable analog and digital noise filters
Pin mapping[edit | edit source]
The Pin mapping is described in the Pinout table section
