SMC532 wani tsarin NFC ne wanda kamfanin SeabreezeRFID ya tsara，Abu ne mai sauki ka cimma NFC mai karatu / kwaikwayi / sa'a zuwa sahun(p2p) ayyuka ta hanyar aika commandsan umarni，umarni daya don cimma hanyar P2P tare da waya, babu buƙatar kulawa da rikice-rikicen hulɗa a cikin NFC Stack, da kuma bada fifiko akan kantattun hanyoyin yarjejeniya na app kamar LLCP / SNEP / NDEF da sauransu,duk mun yi muku duka a cikin MCU, bututu mai amfani ne ga mai amfani, aika da samun bayanai daga gareta amma ba cikakken bayani game da NFC, Samuwa SMC532, NFC abu ne mai sauqi!!!

NFC ba da gaskiya, ginanniyar kayan aikin NFC, tallafi don tashar jiragen ruwa ta UART don karantawa da rubutu kai tsaye, don ikon sarrafawa na iya dacewa da wayoyin hannu da katunan don buɗe ƙofa, amma kuma don samun maɓalli mai ƙarfi, karanta bayanan NFC ta kayan kai tsaye, tashar jiragen ruwa zata iya bunkasa NFC , Ba kwa buƙatar yin nazarin LLCP / NDEF da sauran makarancin yarjejeniya. Aika da misalai da yawa na lambar tushe, wayar ta dace da lambar tushen tsarin gwajin, customizable ci gaba, SeabreezeRFID keɓaɓɓen watsa bayanan P2P.

Sayarwa: don cimma nasarar watsa NFC, ginanniyar kayan aikin NFC, goyan bayan UART tashar jiragen ruwa kai tsaye karanta da rubutu, don ikon sarrafawa na iya dacewa da wayoyin hannu da katunan don buɗe ƙofa, amma kuma don samun maɓalli mai ƙarfi, karanta NFC bayanan tashar tashar jiragen ruwa, Kirkirar NFC baya buƙatar bincike kan dunƙule kamar LLCP / NDEF.
