We have launched a new serial port screen chip scheme in the charging pile market ：LT776, This product has two-dimensional code function .

Technical communication ：13602504660

LT776 It's an efficient Uart TFT Serial port screen control chip , Support DCMI Camera interface and Can bus , It combines Cortex-M4 MCU And 2D TFT Graphic display Accelerator , The main function is to provide Uart A serial port communication , Let the master control end MCU The information to be displayed can be easily displayed to... Through simple serial port instructions TFT On the screen . In addition to its own high efficiency M4 MCU outside , The internal hardware also provides 2D Graphics acceleration , To be able to improve TFT Show efficiency , And decrease MCU Time spent processing graphic displays ,LT776 The supported display resolutions are 320*240 （QVGA） To 1024*768（XGA）16bits Of RGB Interface display . LT776 Inside M4 The main frequency can reach 500MHz, contain 256Kbytes Flash、128Kbytes SRAM、2D Graphic acceleration display 、128Mb Display memory , The supported serial port screen instructions include picture display 、GIF Animation display 、 Loop picture display 、 The boot screen displays 、 The progress bar shows 、 Text string display 、 QR code generation 、 Audio broadcast , And achieve the effect of touch function in combination with the touch screen 80 Multiple instructions , coordination Lesheng Semiconductor Co., Ltd Serial port screen development software 、 Simulation software can quickly complete small and medium-sized TFT Serial port screen display scheme . Except for the serial port screen Uart communication interface ,LT776 There are also multiple groups of SCI（Uart） Interfaces can be connected to Bluetooth modules 、WiFi Modules and other components , Also provide USB Interface 、SD card , Analog input AIN、PWM And INT Interrupt and other interfaces , These interfaces can also be set to normal IO Interface , Bring your own at the same time RTC The clock .
Due to the high capacity of Flash And SRAM,LT776 It can also be used as a belt TFT The main controller of the controller MCU To use , It is very suitable for use in TFT-LCD On the electronic products of the screen , Such as all kinds of smart appliances 、 Car dashboard 、 Motorcycle panel 、 Multifunctional transaction machine 、 Industrial control 、 Electronic instruments 、 Medical beauty equipment 、 Testing equipment 、 Charging equipment 、 Water and electricity meter 、 Intelligent speaker with screen and other products .
