Duk nau'ikan allunan haɓakawa da MCU waɗanda ke goyan bayan hanyar sadarwar UART na iya amfani da wannan ƙirar kai tsaye, kuma babu buƙatar shigar da ƙarin direbobi ko shirye-shiryen API.
Saita Tushen da Na'urori
TTL mai waya ta al'ada shine watsa 1 zuwa 1, tsarin watsawa na RFLINK-UART mara waya ta UART zai goyi bayan nau'in 1-zuwa-yawan, tsoho Tushen tashar (#0) bayan kunna wuta tare da na'urar (#1) an haɗa idan kuna da wani. Na'ura mai lamba (#2~# 4). Kuna iya zaɓar gefen na'ura daban-daban da kuke son haɗawa ta hanyar ID0 da ID1 fil a gefen tushen. Don haɗin ID0/ID1 na zaɓin na'urar, da fatan za a koma teburin da ke ƙasa.
ID0, ID1 fil tsoho HIGH ne, za su kasance LOW ta hanyar haɗi zuwa ƙasa.
Lura: Ya kamata a saita gefen na'ura zuwa lambar na'urar da ake buƙata bisa ga farko, tushen zai zaɓi na'urar da aka yi niyya ta hanyar tebur guda.
Kuna iya zaɓar wata na'ura daban don canja wurin saƙonni ta ID0 da ID1 na tushen, yawanci ɗaure ID0 ko/da ID1 zuwa GND. Fiye da haka, tushen tushen kuma zai iya aika siginar Low / High ta hanyar IO fil don zaɓar na'urar da aka yi niyya akan tashi. Don misaliample, a cikin hoton da ke ƙasa, Arduino Nano ya zaɓi Na'urar don haɗawa ta filayen D4 da D5.
Bayan aika madaidaicin siginar High / Low zuwa ID0 da ID1 fil, Tushen Tushen zai katse watsawa tare da ƙarshen haɗin tsohuwar (wato, dakatar da watsawa da karɓa tare da ƙarshen haɗin haɗin). Kuma jira Ƙaramar sigina daga fil ɗin ID_Lat don canzawa zuwa sabon haɗin.
