Tutorial Overview

We offer two methods for updating the UI program for all HMI products: one is via SD card, and the other is through the UART port. The method of updating using an SD card varies depending on the MCU.

For HMI Displays equipped with the LT7689 MCU, simply insert the SD card directly into the module's SD card slot. After inserting the SD card, powering on the HMI Display will automatically initiate the update process.

On the other hand, if the HMI Display utilizes the LT168A MCU, it first needs to be connected to a debugging board. Once powered on, insert the SD card into the slot on the debugging board to complete the update.

To update via the UART port, you will require the LT_Uart_GUI software and a debugging board. Both the software and accessories can be downloaded from our official website or purchased accordingly.
