NRF24L01+ Wireless module Mphamvu yowonjezera SI24R1 2.4G yopanda zingwe yolandirira gawo

Zambiri zamalonda

Mafotokozedwe Akatundu
Tsegulani ma frequency band a ISM, Z yayikulu 0dBm kutumizira mphamvu, kugwiritsa ntchito kwaulere.
Imathandizira njira zisanu ndi imodzi zolandirira deta
1. Kutsika kwamagetsi ogwiritsira ntchito: 1.9 ~ 3.6V Opaleshoni yotsika yamagetsi
2. Kuthamanga kwakukulu: 2Mbps, chifukwa cha nthawi yochepa yotumizira mpweya, imachepetsa kwambiri kugunda kwazomwe zimachitika pamagetsi opanda zingwe (mapulogalamu a 1 Mbps kapena 2Mbps mpweya wotumizira mpweya)
3. Multi-frequency: 125 ma frequency point kuti akwaniritse zosowa za kulumikizana kwamitundu yambiri komanso kulumikizana pafupipafupi
4 Yaing'ono kwambiri: mlongoti womangidwa mu 24GHz, kukula kochepa, 15x29mm (kuphatikiza mlongoti)
5 Kugwiritsa ntchito mphamvu zochepa: Pamene mukugwira ntchito poyankhira njira yoyankhira, kutumiza mpweya wothamanga ndi nthawi yoyambira kumachepetsa kwambiri kugwiritsa ntchito panopa.
6. Mtengo wotsika mtengo: NRF24L01 imagwirizanitsa mbali zonse zothamanga kwambiri zowonetsera zizindikiro zokhudzana ndi RF protocol, monga: kubwezeretsanso kwapaketi ya data yotayika ndi kubadwa kwa zizindikiro zoyankhira, etc. Mawonekedwe a SPI a NRF24L01 akhoza kugwirizanitsidwa ndi hardware SPI doko la kachipangizo kakang'ono kakang'ono kamene kalikonse kapena kufaniziridwa ndi doko la I/O la chip microcomputer imodzi. FIFO yamkati imatha kulumikizana ndi ma microprocessors osiyanasiyana apamwamba komanso otsika. Yosavuta kugwiritsa ntchito yotsika mtengo ya single chip microcomputer.
7 Yosavuta kupanga: chifukwa ulalo wosanjikiza watha. Zophatikizidwa pa module, zosavuta kupanga. Makina otumiziranso ntchito, kuzindikira zodziwikiratu komanso kutumizanso mapaketi a data omwe adatayika, nthawi yotumiziranso nthawi komanso nthawi yotumizira imatha kuwongoleredwa ndi mapulogalamu kuti asungire mapaketi a data omwe sanalandire chizindikiro choyankhira chodziwikiratu, atalandira deta yolondola, gawoli limatumiza chizindikiro choyankhira, palibe chifukwa chokonzekera chonyamulira chodziwikiratu - mawonekedwe osasunthika omwe adamangidwa mu hardware CRC kuzindikira zolakwika ndi point-to-multipoint communication adilesi control packet transmission error counter ndi ntchito yozindikira chonyamulira ingagwiritsidwe ntchito pa frequency hop Kukhazikitsa kumatha kukhazikitsa maadiresi asanu ndi limodzi olandila nthawi imodzi, kutha kutsegula njira yolandirira pini ya Dip2.54MM, Yosavuta pamapulogalamu ophatikizidwa.
