Ukubala ikhowudi ye-CRC:
1.Irejista ye-16-bit ecwangcisiweyo yi-FFFF kwi-hexadecimal (oko kukuthi, zonke ziyi-1).Tsalela le rejista kwirejista ye-CRC.
2. XOR idatha yokuqala ye-8-bit kunye ne-bit esezantsi ye-16-bit yerejista ye-CRC kwaye ubeke umphumo kwirejista ye-CRC.
3.Shifta imixholo yerejista ngasekunene ngesuntswana elinye (ukubhekisa kwisuntswana elisezantsi), gcwalisa eyona bit iphezulu ngo-0, kwaye ujonge eyona bit iphantsi.
4.Ukuba eyona bit ibalulekileyo ngu-0: phinda inyathelo lesi-3 (shift kwakhona), ukuba eyona bit ibalulekileyo ngu-1: irejista ye-CRC iXORed ngepolynomial A001 (1010 0000 0000 0001).
5. Phinda amanyathelo 3 kunye ne-4 kude kube ngamaxesha angama-8 ukuya ekunene, ukuze yonke idatha ye-8-bit iqhutywe.
6.Phinda amanyathelo 2 ukuya ku-5 kwi-8-bit elandelayo yokucubungula idatha.
7.Irejista ye-CRC ekugqibeleni ifunyenwe yikhowudi ye-CRC.
8. Xa isiphumo se-CRC sifakwe kwisakhelo solwazi, i-bits ephezulu kunye nephantsi iyatshintshwa, kwaye i-bit ephantsi iqala.
Xhuma i-sensor ngokwemiyalelo kwindlela yocingo, emva koko faka izikhonkwane ze-probe zenzwa kumhlaba ukulinganisa ukufuma, kwaye uvule amandla kunye nomqokeleli wokutshintsha ukufumana ubushushu bomhlaba kunye nomswakama kwindawo yokulinganisa.
1. Nceda ujonge ukuba ukupakishwa kusemgangathweni kwaye ujonge ukuba imodeli yemveliso iyahambelana nokukhetha.
2. Musa ukudibanisa ngombane, kwaye emva koko uvule emva kokujonga i-wiring.
3. Musa ukutshintsha izinto okanye iingcingo ezithe zathengiswa xa imveliso iphuma kumzi-mveliso.
4. Uluvo sisixhobo esichanekileyo.Nceda ungayiqhawuli ngokwakho okanye uchukumise umphezulu we-sensor ngezinto ezibukhali okanye ulwelo oludlekayo ukuze uphephe ukonakalisa imveliso.
5.Nceda ugcine isatifikethi sokuqinisekisa kunye nesatifikethi sokuhambelana, kwaye usibuyisele kunye nemveliso xa ulungisa.
1. Xa imveliso ifunyenwe, umboniso ubonisa ukuba ixabiso li-0 okanye lingaphandle koluhlu.Khangela ukuba kukho isithintelo kwizinto zangaphandle.Umqokeleli akanakukwazi ukufumana ulwazi ngokuchanekileyo ngenxa yeengxaki zocingo.Nceda ujonge ukuba i-wiring ichanekile kwaye yomelele;
2. Ukuba ayizizo zizathu zingasentla, nceda uqhagamshelane nomvelisi.
