The USBee Test Pods are a product invented in 1998 and was sold until the end of 2015. Due to very successful clones being developed that utilize our USBee software, we had to close the business.

Check http://www.usbee.com/usbeeqxarinc429module-1-1.aspx

Maybe this is the answer to the clones… When there is a lot of cheap hardware clones, try to sell the software for this instead of your own expensive hardware…

I am not using LA as master to control I2C bus.

I monitored the I2C write operation using LA and it is working fine.
But when monitoring the I2C read operation using LA it is not working properly.
In normal I2C read first we send the slave address, ack, register address and then ack and start and read value.
when writing slave address, register address it is working properly.
but when reading value it is always showing 1. Is that due to pull up to keep the pins up when not connected anywhere.

Thanks.

You can’t use it as a master that control I2C bus (send requests etc..).
You should be able to use it to monitor I2C data generated by some other devices..

There is modification idea to add output to this device, take a look at
