I2C Protocol

The Inter-Integrated Circuit (I2C) protocol is widely used for short-distance, intra-board communication. AQPXLIB supports I2C bus emulation, allowing you to create buses, attach targets, and perform controller operations.

Supported Features

• Bus Creation: Initialize I2C buses with configurable SCL/SDA pins.
• Targets: Emulate 32-bit register targets, byte-addressable memory targets, or FIFO targets.
• Electrical Configuration: Adjust voltage, pull-up resistors, and thresholds.

Classes

• PxI2CController: The standard I2C controller interface.
• PxI2C32BitRegisterTarget: A generic I2C target with 32-bit registers.
• PxI2C8BitAddressMemoryTarget: A byte-addressable memory target with 8-bit sub-addressing.
• PxI2CFifoTarget: An I2C target with host-accessible RX/TX FIFOs and packeted bus events.
• PxI2C4KbMemoryTarget: A byte-addressable memory target with 16-bit sub-addressing (4 KB).
