Introduction
A new LT develop board needs to be programmed before put into operation. Users must first program the
[Bootloder], then the [MCU_Code.bin] to LT develop board, and finally the [UartTFT_Flash.bin] to SPI Flash.
A bootloader is a program used to initialize the peripherals such as SD card, USB disk interface, VCOM,
and Uart port etc, based on the target develop board. A bootloader is usually programmed toLT develop board
before shipment.
MCU_Code.bin is the main program for operating LT develop board; and UartTFT_Flash.bin is the file
with the image data including pictures, animations, fonts etc, usually developed by users..
This manual is to illustrate how users may utilize a VCOM programming tool, namely LT_VCOM_GUI, to
program MCU_Code.bin and UartTFT_Flash.bin to LT develop board.
