I am using the Aardvark I2C/SPI Host Adapter on an I2C device with multiple registers. The address of the device I need to communicate with is 0xA6. On that device, I will be writing to registers 0xC and 0xD with a sequential write in python. The Aardvark Software API has an aa_i2c_write function, but it only takes 4 arguments: handle, device_address, flags, and value. How do I include the register address of the selected device? I tried shifting the device address by 8 bits and using the OR operation on the register address, but that did not work.

In various industries, from automotive to aerospace, reliable data transfer is crucial for the development of cutting-edge technology and life-saving systems. The CAN protocol, introduced in the 1980s, quickly became a popular solution for device communication, enabling real-time data exchange in a compact, physical form. The CAN protocol relies on two elements: the CAN controller and CAN transceiver. Together, they help construct an extremely reliable and efficient means for data transfer and communication within larger systems. Working alongside the microcontroller, CAN transceivers and controllers execute several tasks to manage data and transmit messages throughout the system, ensuring it is functioning optimally. Knowing how these components work individually and together is essential when working with and debugging CAN communication.

I am using a Promira Serial Platform with SPI Active - Level 1 Application and Promira Software API I2C/SPI Active connected to the lab computer via Ethernet connection. I have questions about the queue mechanism - I see it takes about 500uS for the Promira platform to clear a queue, which was confirmed with a logic analyzer.
