4. Tsanangudzo dzePin uye Hardware Interface
Module yeE32-900T20D ine musoro wepin wakajairika wekubatanidza. Kuti uwane ruzivo rwakadzama nezvepinout, kusanganisira mabasa chaiwo eVCC, GND, TX, RX, AUX, M0, uye M1 pins, ndapota tarisa kune datasheet repamutemo reEBYTE E32-900T20D rinowanikwa pamugadziri. webNzvimbo yacho. Kubatanidza mapini aya zvakanaka kune microcontroller yako kana mudziyo wehost kwakakosha kuti ushande nemazvo.
- VCC: Kuiswa kwemagetsi.
- GND: Ground connection.
- TX: Tumira data rinobuda (rinobatanidza neRX yemubati).
- RX: Gamuchira data input (inobatanidza neTX yehost).
- AUX: Pini yekubatsira, inowanzo shandiswa kuratidza mamiriro (semuenzaniso, data ragadzirira).
- M0, M1: Mapini ekusarudza modhi, anoshandiswa kugadzirisa modhi yekushandisa.
5. Setup uye Connection
- Magetsi: Batanidza pini yeVCC kune simba rakagadzikana riri mukati mevhoriyamu yakatarwa yemoduletage range. Batanidza GND pasi pesystem.
- Kukurukurirana kweSeri: Batanidza TX pin yemodule neRX pin ye microcontroller yako kana host device, uye RX pin yemodule neTX pin ye host device yako. Iva nechokwadi chekuti zvishandiso zvese zvine nzvimbo yazvinowirirana.
- Antenna Connection: Batanidza antenna inoenderana ne868MHz kana 915MHz zvakachengeteka kune chinongedzo cheantenna yemodule. Antenna isina kubatana zvakanaka kana kuti isipo inogona kukuvadza module.
- Sarudzo yeModhi: Shandisa mapini eM0 neM1 kuti ugadzire modhi yekushanda yaunoda. Tarisa padatasheet kuti uwane magadzirirwo chaiwo emapini emodhi yega yega.
- Software Configuration: Gadzirisa marongero eUART emudziyo wako wehost (baud rate, parity, stop bits) kuti aenderane nemarongero emodule kana configured. Module inogona kugadzikiswa kuburikidza nemirairo yeAT kuburikidza ne serial interface.
6. Maitiro Okushandisa
Module yeE32-900T20D inotsigira nzira ina dzakasiyana dzekushanda, imwe neimwe yakagadzirirwa zvinodiwa zvakasiyana zvekushandisa:
- Transmission Mode: Iyi ndiyo nzira yekutumira data yakajairika inoonekera, inowanzoshandiswa pakuchinjana data nguva dzose.
- Maitiro Ekumuka: Yakagadzirirwa maapplication ane simba shoma, iyi modhi inobvumira chinotumira kumutsa chinogamuchira nekuwedzera otomatiki kodhi yekumutsa data risati ratumirwa.
- Simba Kuchengetedza Mamiriro: Munzira iyi yekugamuchira chete, module inoshandisa simba shoma. Inogona kugamuchira data asi haigone kutanga kutumira.
- Deep Sleep Mode: Nzira yekushandisa simba shoma, uko kushandiswa kwesimba kwemodule kwakaderera zvakanyanya (semuenzaniso, kusvika ku2uA), yakakodzera midziyo inoshandisa bhatiri inoda basa shoma.
