Nangona kunjalo, iindleko zabo zokugcina zincinci. | Iindleko zokuqala zomcu we-LED onedilesi yeSPI zifanelekile. Basebenzisa abalawuli be-SPI abangabizi kunye ne-microcontrollers, ezifikelelekayo. |
Yeyiphi eNgcono kwiProjekthi yakho: DMX512 Okanye iSPI LED Strips?
Ekukhetheni umcu ofanelekileyo weprojekthi yakho, kufuneka uqwalasele iimfuno zakho kuqala. Ukuba usebenza kwiprojekthi enkulu, DMX512 iintambo ze-LED eziphathwayo lukhetho lwakho olungcono. Zihlala ixesha elide kwaye ziyilelwe ukufakwa kweengcali. Unokuzibekela ukukhanyisa kweqonga, ukwakha, okanye ukukhanyiswa kwesiganeko sangaphandle.
Olunye uncedo lokusebenzisa i-DMX512 iintambo ze-LED ezinokulungiseka kukuba yiprothokholi esemgangathweni yamazwe ngamazwe. Ukusebenzisa umlawuli ofanayo we-DMX512 unokuxhasa iindidi ezahlukeneyo ze-DMX512 ICs. Ke, uya kuba nokuguquguquka ngakumbi xa usebenzisa le micu kwiprojekthi yakho. Nangona kunjalo, zonke ezi ndawo zandisiweyo zenza i-DMX512 imicu ekwaziyo ukujongana nayo ibize kakhulu. Ke, kufuneka ube nohlahlo lwabiwo-mali olufanelekileyo ukufaka ezi zilungiso.
Nangona kunjalo, imichilo ye-LED ekwazi ukujongana ne-SPI ilungile ukuba uye kwimisebenzi ye-DIY okanye nayiphi na iprojekthi encinci ukuya kwephakathi. Ezi zilula ukuzifaka; nawuphi na owaqalayo unokuwabeka ngaphandle kolwazi oluninzi lobugcisa. Nangona kunjalo, i-drawback ebalulekileyo kukuba i-SPI ayisiyoprotocol esemgangathweni. Oku kuthetha ukuba ayingabo bonke abalawuli beSPI abahambelanayo ne-SPI IC nganye. Nangona kunjalo, zizisombululo ezinohlahlo-lwabiwo mali kakhulu xa kuthelekiswa nemicu ye-LED ephathwayo ye-DMX.
Ke, ngokuqwalasela zonke ezi zinto, unokukhawuleza wenze isigqibo ngeyona ilungileyo yeprojekthi yakho. Ukuze ufumane isikhokelo, funda Esona sikhokelo siGqibeleyo sokuDibana ne-LED Strip.
