He aha te pūwetetā DMX512-SPI?

Ko te taputapu e huri ana i ngā tohu whakahaere DMX512 ki ngā tohu SPI (Serial Peripheral Interface) e mōhiotia ana ko te DMX512-SPI decoder. Ko te whakahaere i ngā rama atamira me ētahi atu taputapu whakangahau e whakamahi ana i te kawa paerewa DMX512. Ko te atanga raupapa tukutahi, SPI rānei, he atanga rongonui mō ngā taputapu matihiko pēnei i ngā microcontroller. Hei whakahaere i ngā taputapu SPI, pēnei i ngā rama pika LED,ngā rīpene LED mamati, ka taea te whakamāori i ngā tohu whakahaere DMX ki ngā tohu SPI mā te whakamahi i tētahi pūwetewete DMX512-SPI. Mā tēnei ka taea te whakahaere rama me te uaua ake, me te auaha ake i ngā wā o ngā whakaaturanga me ngā huihuinga.

Ka hiahiatia ēnei mea hei hono i tētahi rīpene LED ki tētahi pūwetewete DMX512-SPI:

Rīpene rama: Me whakarite kei te whakamahi tō rīpene rama i te whakawhitiwhiti SPI me te mana whakahaere DMX. Ko ēnei momo rīpene rama he maha ngā ara iahiko whakauru (IC) kua hangaia hei whakahaere i ia pika.

Ka hurihia ngā tohu whakahaere DMX hei tohu SPI ka taea e te rīpene LED te whakamaori e te pūwetetā DMX512-SPI. Me whakarite kia taea e te pūwetetā te whakauru i te nui o ngā pika e hiahiatia ana, ā, kia hototahi hoki ki tō rīpene LED.

Kaiwhakahaere DMX: Hei tuku i ngā tohu whakahaere ki te pūwetewete DMX512-SPI, me whai kaiwhakahaere DMX koe. Ka taea e ngā kaiwhakahaere DMX te whakamahi i ngā papatohu taputapu, i ngā kaiwhakahaere pūmanawa, i ngā taupānga pūkoro rānei.

Ko ngā tukanga hononga mō te pūwetetā DMX512-SPI me te rīpene LED e whai ake nei:

Me whakarite kua tatū te pūwetetā DMX512-SPI, ā, kua whirihorahia kia taea ai te whakamahi me tō pūmana DMX.

Whakamahia he taura DMX noa hei hono i te putanga DMX o te kaiwhakahaere DMX ki te tāuru DMX o te pūwetetā DMX512-SPI.

Honoa te putanga SPI o te pūwhakamātautau DMX512-SPI ki te tāuru SPI o te rīpene LED. Tērā pea ka hiahiatia he hononga rerekē mō ngā waea karaka (CLK), raraunga (RARAUnga), me te whenua (GND) mō te pūwhakamātautau me te rīpene LED motuhake.

Honoa te pūwhakamātautau DMX512-SPI, te rīpene LED, me te pūtake hiko. Me whakarite kei te whiwhi ngā taputapu e rua i te ngaohiko me te iahiko tika mai i te pūtake hiko. Mō te hononga hiko, me whai i ngā taunakitanga a te kaihanga.

Ko te tuku i ngā tohu whakahaere DMX mai i te kaiwhakahaere ki te pūwhakamātautau te taahiraa whakamutunga o te whakamātautau i te tatūnga. Ka hurihia e te pūwhakamātautau ngā tohu DMX ki ngā tohu SPI ka whakamahia hei whakahaere i ngā pika rīpene LED takitahi.

He mea nui kia maumahara ka rerekē pea ngā tikanga me ngā hononga motuhake i runga i te momo me te waitohu o tō pūwhakamātautau DMX512-SPI me te rīpene LED. Mō ngā tohutohu tika, tirohia tonu te aratohu kaiwhakamahi me ētahi atu rauemi i tukuna mai e ngā kaihanga.

Kei te Mingxue LED he COB/CSP, he rīpene Neon, he ngaohiko teitei me te horoi pakitara.whakapā maiā, ka taea e mātou te tuku atu i ētahi atu kōrero mō ngā rama rīpene LED.
