Tool/software:

I am testing the i2c command via USB OTG.

But I couldn't communicate directly through the usb otg.

Can I control the i2c command via UART0 instead of USB OTG?

Hello User,

Welcome to the E2E forums and thank you for your interest in DLP Technology. We hope to assist you with your questions.

When you are using the USB OTG can you even connect with the EVM GUI such as below? Did you check your device manager if the USB device pops up?

Can you try using a laptop with just a normal USB cable?

UART is normally for debug purposes and not used as the main form of communication.

Regards,

Alex Chan

I already use the EVM GUI that communicate successfully. But I want to control using our external MCU like arduino directly. Could I use this way using another port on 471TP EVM?

Hello User,

DLPC6540 controller in the DLP471TPEVM inly supports two interfaces for commands i.e USB and IIC.
Please refer to the DLPC6540 programmer's guide available at: https://www.ti.com/lit/pdf/dlpu110
