Detailed Description

I2C peripheral handle.

Represents an I2C configuration as resolved from hardware manifests. Includes peripheral number, pin mappings, and bus speed.

Examples:

STM32H7 I2C1 on PB8/PB9: I2cHandle{1, 1, 8, 4, 1, 9, 4, 100000}
STM32H7 I2C2 on PB10/PB11: I2cHandle{2, 1, 10, 4, 1, 11, 4, 400000}
