The ST7796S is capable of connecting directly to an external microprocessor, and accepts 8-bit/9-bit/16-bit/18-bit parallel interface, SPI, and the ST7796S also provides MIPI interface. Display data can be stored in the on-chip display data RAM of 320x480x18 bits. It can perform ...
Computer Memory Basics If your computer's CPU had to constantly access the hard drive to retrieve every piece of data it needs, it would operate very slowly. When the information is kept in memory, the CPU can access it much more quickly. 5/26/2018 ...
