Ib yam li ntawd, tib neeg nug, dab tsi yog GPIO pins siv rau ntawm Raspberry Pi?
GPIO yog koj tus qauv tus pin uas tau siv tig cov khoom siv rau thiab tawm. Piv txwv li, ib tug LED. I2C (Inter-Integrated Circuit) tus pin tso cai rau koj txuas thiab tham nrog cov khoom siv kho vajtse uas txhawb cov txheej txheem no (I2C Protocol). Cov txheej txheem no feem ntau yuav siv li ob tus pin.
Puas yog GPIO pins analog lossis digital?
Thaum tag nrho GPIO pins muab xwb digital cov tswv yim lossis cov zis, PWM tuaj yeem siv tau (nrog rau cov khoom siv hluav taws xob sab nraud tsawg heev - qhov qis-pass-filter) kom tsawg kawg nkaus analog teeb liab.
