Okwu mmalite nke ILI9341 Controller
The ILI9341 controller supports a maximum resolution of 240*320 and a 172800-byte GRAM. It also supports 8-bit, 9-bit, 16-bit, and 18-bit parallel port data buses. It also supports 3-wire and 4-wire SPI serial ports. Since parallel control requires a large number of IO ports, the most common one is SPI serial port control. The ILI9341 also supports 65K, 262K RGB color display, display color is very rich, while supporting rotating display and scroll display and video playback, display in a variety of ways. The ILI9341 controller uses 16bit (RGB565) to control a pixel display, so it can display up to 65K colors per pixel. The pixel address setting is performed in the order of rows and columns, and the incrementing and decreasing direction is determined by the scanning mode. The ILI9341 display method is performed by setting the address and then setting the color value.
Okwu Mmalite nke Usoro Nkwukọrịta SPI
Egosipụta oge ụdị ederede nke ụgbọ ala SPI 4 4-waya n'ọnụọgụ a:
CSX bụ nhọrọ mgbawa ohu, a ga-emekwa mgbawa ahụ naanị mgbe CSX nọ na ọkwa dị ala. D/CX bụ ntụtụ njikwa data/iwu nke mgbawa. Mgbe DCX na-ede iwu na ọkwa dị ala, edere data na ọkwa dị elu SCL bụ elekere ụgbọ ala SPI, nke ọ bụla na-ebili elu na-ebufe 1 bit nke data; SDA bụ data nke SPI na-ebufe, nke na-ebufe data 8 n'otu oge. E gosipụtara usoro data ahụ na foto a:
Nke mbụ dị elu, bufee mbụ. Maka nzikọrịta ozi SPI, data nwere oge nnyefe, yana nchikota nke oge elekere (CPHA) na polarity elekere (CPOL): Ọkwa CPOL na-ekpebi ọkwa steeti na-abaghị uru nke elekere synchronous serial, yana CPOL=0, na-egosi. ọkwa dị ala. Usoro mgbasa ozi ụzọ abụọ CPOL Mkparịta ụka ahụ enweghị mmetụta dị ukwuu; The elu nke CPHA na-ekpebi ma Oghere Usoro synchronous elekere na-anakọta data na mbụ ma ọ bụ nke abụọ elekere na-awụlikwa elu onu, Mgbe CPHL = 0, rụọ data collection na mbụ mgbanwe ihu; Nchikota nke abụọ a bụ ụzọ nkwurịta okwu SPI anọ, na SPI0 na-ejikarị na China, ebe CPHL=0 na CPOL=0
