I am starting to use the Komodo CAN Duo Interface with the loopback test that was provided with the Komodo Software API. I have tried many times, but I cannot get the test to run, and it’s not consistent: sometimes port A or port B will not enable; sometimes the write command fails.  Am I missing something? What do I need to get this function to work?

If you're an embedded systems engineer, you may want to build a product that either takes input from a human operator or delivers outputs to an operator through a human-readable interface. When such functions are to be implemented, it is common for engineers to use a special type of communication protocol known as the Human Interface Device (HID) protocol.

I am looking at the Beagle USB 5000 v2 SuperSpeed Protocol Analyzer - Standard Edition, which supports both USB 2.0 and USB 3.0 at a reasonable cost. For some cases, I need to store large amounts of data; some tests run for days. How can I store data that exceeds the size of the internal memory buffer?

USB classes can be defined as groups of similar devices, such as Audio, Human Interface Devices (HID), and Mass Storage, that use a standard set of commands which allow them to share a common USB class driver.

I am using a Komodo CAN Duo Interface with the Komodo Software API. I am trying to control the GPIO pins for output signals. I think I have done everything necessary, but the GPIO pins are not responding as expected. With my program, pin 4 stays low like this:

The USB protocol was introduced in 1996 as a way to institutionalize a more widespread, uniform cable and connector that could be used across a multitude of different devices. The idea was to simplify the connection of devices to and from a host computer. The protocol is currently maintained and regulated by the USB Implementors Forum or better know as USB-IF. This group sets standards that all USB devices must follow in order to be compliant with the technology and work properly across all USB compatible devices.

I am using the Aardvark I2C/SPI Host Adapter and Aardvark Software API to program and read an I2C EEPROM device, the AT24C32. This I2C device has a 2-byte address and uses 2-byte data. Is there a way to use your API functions for that? Your API functions are designed for 8-bit data, but this device has a  16-bit address. The programming language I am using is C.

The I2C serial communication protocol was first invented by the Philips Semiconductor company, now known as NXP Semiconductors, in 1982. Now approaching its 40th anniversary, the protocol offers an effective means of short-distance intra-board communication that is ideal for embedded systems and micro-computing applications where the primary design concerns are simplicity and low manufacturing cost.
