Kuv (Somanshu Choudhary) sawv cev ntawm Dcube thev naus laus zis kev lag luam mus rau kev tswj hwm ntawm I2C raws tu qauv siv Arduino nano thiab MCP23008.

Kauj ruam 1: Txheej txheem cej luam

Txheej txheem cej luam
Txheej txheem cej luam
  • Cov cuab yeej MCP23X08 muab 8-ntsis, lub hom phiaj dav, nthuav dav I/O nthuav dav rau I2C tsheb npav lossis daim ntawv thov SPI.
  • MCP23X08 muaj ntau yam 8-ntsis teeb tsa cov npe rau kev tawm tswv yim, tso tawm thiab xaiv polarity. Tus txheej txheem txheej txheem tuaj yeem ua haujlwm rau I/Os li kev nkag los lossis tawm los ntawm kev sau I/O teeb tsa me ntsis. Cov ntaub ntawv rau txhua qhov kev tawm tswv yim lossis tso tawm raug khaws cia hauv qhov sib nkag tau nkag los lossis tso tawm npe. Lub polarity ntawm Kev Nkag Mus Nkag Chaw Nkag tuaj yeem hloov pauv nrog Polarity Inversion register. Txhua qhov sau npe tuaj yeem nyeem los ntawm tus txheej txheem.
