4. Ngā Whakamāramatanga Pin me te Atanga Pūmārō

Kei roto i te waeine E32-900T20D he pane pine paerewa mō te whakaurunga. Mō ngā mōhiohio taipitopito mō te pinout, tae atu ki ngā mahi motuhake mō ngā pine VCC, GND, TX, RX, AUX, M0, me M1, tirohia te pepa raraunga EBYTE E32-900T20D mana kei runga i te paetukutuku a te kaihanga. webpae. He mea nui te hononga tika o ēnei pine ki tō pūmana iti, ki tō pūrere manaaki rānei mō te mahi tika.

• VCC: Whakauru hiko.
• GND: Hononga whenua.
• TX: Tukuna te putanga raraunga (hono atu ki te RX o te kaihautū).
• RX: Whiwhi raraunga whakauru (hono atu ki te TX o te kaihautū).
• AUX: He pine āwhina, e whakamahia ana mō te tohu tūnga (hei tauira, kua rite ngā raraunga).
• M0, M1: Ngā pine kōwhiringa aratau, e whakamahia ana hei whirihora i te aratau whakahaere o te kōwae.

5. Tatūnga me te Hononga

1. Tuku Hiko: Honoa te pine VCC ki tētahi pūtake hiko pumau i roto i te rōrahi kua tohua e te kōwae.tagawhe e. Honoa te GND ki te whenua pūnaha.
2. Whakawhitiwhiti Rangatū: Honoa te pine TX o te kōwae ki te pine RX o tō pūmana iti, o tō pūrere manaaki rānei, me te pine RX o te kōwae ki te pine TX o tō pūrere manaaki. Me whakarite kei te whai hononga ngā pūrere e rua.
3. Hononga Antenna: Āpitihia he pūihi hototahi 868MHz, 915MHz rānei ki te hononga pūihi o te kōwae. Mēnā kāore i te hono tika, ka ngaro rānei te pūihi, ka kino pea te kōwae.
4. Kōwhiringa Aratau: Whakamahia ngā pine M0 me M1 hei whakarite i te aratau whakahaere e hiahiatia ana. Tirohia te pepa raraunga mō ngā whirihoranga pine motuhake mō ia aratau.
5. Whirihoranga Pūmanawa: Whirihorahia ngā tautuhinga UART o tō pūrere manaaki (reiti baud, ōritetanga, ngā moka mutu) kia ōrite ki ngā tautuhinga taunoa, ngā tautuhinga whirihora rānei o te kōwae. He maha ngā wā ka taea te whirihora i te kōwae mā ngā whakahau AT mā te atanga raupapa.

6. Aratau Mahi

E tautoko ana te kōwae E32-900T20D i ngā momo whakahaere motuhake e whā, ia momo i arotauhia mō ngā whakaritenga tono rerekē:

• Aratau Whakawhiti: Koinei te aratau tuku mārama paerewa, e whakamahia whānuitia ana mō te whakawhiti raraunga tonu.
• Aratau Whakaara: He mea hanga mō ngā tono iti-mana, ka taea e tēnei aratau te whakaoho i te kaiwhiwhi mā te tāpiri aunoa i tētahi waehere whakaoho i mua i te tuku raraunga.
• Aratau Tiaki Mana: I tēnei aratau kaiwhiwhi-anake, he iti ake te hiko e pau ana i te kōwae. Ka taea e ia te whiwhi raraunga engari kāore e taea te tīmata i ngā tuku.
• Aratau Moe Hohonu: Ko te aratau iti rawa te whakamahinga hiko, ka tino whakaitihia te whakamahinga hiko katoa o te kōwae (hei tauira, ki te 2uA), he mea tino pai mō ngā taputapu pākahiko e hiahia ana kia iti noa te mahi.
