Design summary based on F2812 and LCD interface circuit 1. Hardware environment: TMS320F2812A, EPM240T100C5, Hansheng LCD12864 (ST7920); TMS320F2812A, EPM240T100C5, Jinpeng Electronic LCD1602OCMJ2X8A. 2. Solution introduction: Since the DSP has a relatively high working speed, the LCD is a relatively low-speed external device. In order to meet the functional requirements without reducing the working efficiency of the DSP, we use Altera\'s MAXⅡ series CPLD chip as the DSP interface control chip.
