Brief description:

       As the serial port touch screen is developing from the original industrial application to the consumer world, many devices needing human-machine interfaces have to upgrade from the original monochrome dot matrix screen to the TFT color screen. The TFT color screen makes the pictures more colorful and vivid and interactions more effective, greatly improving the general competitiveness of a product.

     The serial port touch screen necessitates the support of the effect of quick screen response while requiring the MCU to store certain amounts of picture modules inside. The GD32 MCU is the No. 1 option for this application solution. With the dominant frequency of the GD32 MCU 10X up to 108MHz, it has the EXCM bus, which helps to achieve high-speed driving of low-/mid-end TFT screens. Besides, the GD32 MCU 20X series has a dominant frequency up to 120MHz and a built-in hardware drive unit for the TFT screen. The internal flash capacity is up to 3Mb.
