| Abstract: | The hardware resource and corresponding peripherals of TMS320F2812 DSP are introduced, the interface circuits as well as the control system and press-key structure of the 19264 LCD device are discussed. Based on these factors, the GPIO ports on TMS320F2812 are used to design press-key and LCD interface circuits. Testing and simulation show that this design is workable. |
