TLA2024: Read TLA2024 with USB

Part Number: TLA2024
Other Parts Discussed in Thread: , ADS1115

Hi Experts,

Our customer would like to ask if it would be possible to communicate with TLA2024 via I2C-to-USB adapters like https://www.adafruit.com/product/4471 for debug purposes using your web software or it only supports your EVB?

The question was how to not use EVB and still use web-based software to read the IC.

We hope to receive your advise. Thank you.

Best regards,
Gerald

    Hi Gerald,

    The TLA2024EVM-PDK is using a USB interface for communication but the protocol uses CDC (virtual COM port) which is not a direct I2C interface.  The I2C communication is from the MSP432E to the TLA2024 and then the data is rerouted to the USB interface using CDC.  So the EVM GUI software is not using I2C for the communication to the PC and the GUI cannot be used with other devices or interfaces.

    If there is other GUI software that may come with the I2C-to-USB interface, the EVM could be connected to the I2C tool.  In the past I have used the Aardvark tool which has terminal type GUI interface where the device can be programmed and conversion data read.

    As a programming tool aid, there is example 'C' code that can be useful.  The code is primarily based on the ADS1115 which is the superset device and very similar to the TLA2024.

    Best regards,
