xav tias lub sensor siv 16-ntsis tus lej lossis koj xav tsim tus lej uas ib txwm yog 16-ntsis. Qhov ntawd yog thaum siv "int16_t". Nws yog ib txwm 16 khoom ntawm txhua lub Arduino boards.
int16_t yog dab tsi?
int16_t is a 16bit integer. uint16_t yog unsigned 16-ntsis integer. Tib yam siv rau 8-ntsis, 32-ntsis thiab 64-ntsis hloov pauv. Nws feem ntau yog siv los ua cov kev pab cuam hla platform. Piv txwv li, Arduino integers (int) yog 2 byte, tab sis hauv cov computers hauv tsev tus lej yog 32 ntsis.
Kuv yuav tsum siv int lossis int16_t?
int tuaj yeem yog nyob ntawm cov khoom siv kho vajtse thiab feem ntau yog 16 lossis 32 ntsis. Txawm li cas los xij, an int16_t yog ib txwm 16 me ntsis, tsis hais txog kev kho vajtse. Nws yuav mus tsis ncaj ncees lawm thaum koj muaj 32 ntsis architecture (rau ib qho int), thiab koj yuav nrum nws mus rau ib qho int16_t, dua li koj plam MSB 16 ntsis.
Dab tsi yog int16_t hauv C?
Piv txwv li, lub npe int16_t qhia a 16-ntsis kos npe tus lej hom thiab lub npe uint32_t qhia 32-ntsis tsis tau kos npe tus lej. Txhawm rau ua kom cov npe no muaj rau ib qho kev pab cuam, suav nrog cov inttypes. h header ntaub ntawv. … Cov kev xaiv tshiab no hu ua hom dav dav.
uint32_t txhais li cas?
uint32_t is a tus lej uas lav 32 khoom . Tus nqi yog unsigned, txhais tau hais tias qhov ntau ntawm qhov tseem ceeb mus ntawm 0 mus rau 232 - 1. uint32_t ptr; tshaj tawm tus pointer ntawm hom uint32_t, tab sis tus pointer yog uninitialized,uas yog, tus pointer tsis taw tes rau qhov twg tshwj xeeb.
