FES4335 is a low cost, high efficiencyand smart of TFT-LCD display control module which can provide characters or 2D graphics application within an embedded 768KB of display RAM.
FES4335 offers serial interface (UART-TTL) to establish a hardware communication with an external simple MCU (as like 8051 etc.), and providing the “Commands Table” for graphical effect calling and execution.
According to the “Commands Table” of graphics APIs, the external MCU only need to transmit the corresponding command code with parameters into FES4335 over serial interface. The command decoder inside of FES4335 would go to implement the graphics task by automatically.
