Selelekela ho ST7789H2 Controller
Selaoli sa ST7789H2 se tšehetsa qeto e phahameng ea 240 * 320 'me se na le GRAM ea 172800 byte ka boholo. Ka nako e le 'ngoe e ts'ehetsa 8-bit, 9-bit, 16-bit, le 18-bit parallel port data libese, hammoho le 3-wire le 4-wire SPI serial port. Ka lebaka la palo e kholo ea likou tsa IO tse hlokahalang bakeng sa taolo e ts'oanang, taolo ea boema-kepe ea SPI ke eona e sebelisoang haholo. ST7789H2 e boetse e ts'ehetsa ponts'o ea mebala ea 65K le 262K RGB, e nang le mebala e metle ea ponts'o. E boetse e ts'ehetsa ponts'o ea ho potoloha le ho tsamaisa, hammoho le ho bapala video, ka mekhoa e fapaneng ea ponts'o.
The ST7789H2 controller uses 16bit (RGB565) to control the display of one pixel, so each pixel can be displayed display up to 65K colors. The pixel address is set in the order of rows and columns, with the increasing le decreasing direction determined by the scanning method fixed. The ST7789H2 display method follows the process of setting the address first and then setting the color value.
