Te kaupapa mahi

Introduction to ITI9488 Controller

Ko te kaiwhakahaere ITI488 e tautoko ana i te taumira teitei o te 320*480 me te 345600-byte GRAM. E tautoko ana hoki i te 8-bit, 9-bit, 16-bit, 18-bit me te 24-bit nga pahi raraunga tauranga whakarara. Kei te tautoko hoki i nga tauranga rangatū 3-waea me te 4-waea SPI. I te mea he nui te taumira tautoko me te nui o nga raraunga ka tukuna, ka tangohia te tuku tauranga whakarara, ka tere te tuku. Kei te tautoko hoki a ITI9488 i te 65K, 262K me te 16.7M RGB whakaatu tae, he tino taonga te tae whakaatu, i te tautoko i te whakaaturanga hurihuri me te whakaatu panuku me te purei ataata, whakaatu i roto i nga momo huarahi.
The ITI9488 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 ITI9488 display method is performed by setting the address and then setting the color value.

He kupu whakataki ki te whakawhitiwhiti tauranga whakarara

Ko te wa aratau tuhi korero tauranga whakarara e whakaatuhia ana i raro nei:Ko te wa o te aratau panui korero tauranga whakarara e whakaatuhia ana i te ahua i raro nei:Ko te CSX he tohu tohu maramara mo te whakaahei me te whakakore i nga korero tauranga whakarara, he iti te kaha
Ko te RESX he tohu tautuhi o waho, he iti te kaha
Ko D/CX te raraunga, tohu tohu whakahau ranei, 1-tuhi raraunga, tawhā whakahau ranei, 0-tuhi whakahau
Ko te WRX he tohu whakahaere raraunga tuhi
