Imiyalo yokusetshenziswa komkhiqizo
Incazelo Yokusebenza:
I-PmodWiFi inikeza usekelo lwe-IEEE 802.11b/g/n lwezinhlelo zokusebenza ezishumekiwe ngamanani edatha angu-1 no-2Mbps. Iklanyelwe ukusetshenziswa nemindeni ye-Microchip microcontroller (PIC18, PIC24, dsPIC33, ne-PIC32) kanye ne-Microchip TCP/IP Stack.
1.1 Isixhumi esibonakalayo:
Isixhumanisi esiyinhloko sokuxhumana ne-PmodWiFi ibhasi le-SPI. I-PmodWiFi iphinde inikeze iphinikhodi esebenzayo yokuphazamiseka okuphansi (~INT) kanye nephinikhodi ye-RST yokusetha kabusha izingxenyekazi zekhompuyutha.

Ukunikezwa kwamandla kagesi:
I-PmodWiFi idinga i-voltage engu-2.7V-3.6Vtage. Amandla kagesi angu-3.3VtagI-e itholakala kuwo wonke amabhodi esistimu ye-Digilent futhi inikezwa njengengxenye yezinga lokusebenzisana le-Pmod elinezintambo ezingu-12. Qinisekisa ukuthi ibhodi lesistimu liyagxuma ukuze linikeze i-3.3V kumojula ngaphambi kokufaka amandla ebhodini.
Ukuze uthole ulwazi olwengeziwe, bheka imininingwane ye-MRF24WB0MA etholakala kwaMicrochip's webindawo.
Kuphelileview
I-PmodWiFi inikeza ukufinyelela kwe-Wi-Fi ngemojula ye-transceiver yomsakazo we-Microchip® MRF24WG0MA Wi-Fi™. Abasebenzisi bangaxhumana nechip ethobela i-IEEE 802.11g nge-SPI futhi bathole amanani edatha afika ku-54 Mbps.
Izici zifaka:
- I-IEEE 802.11-i-transceiver ye-RF ehambisanayo
- Thumela idatha koku-1 no-2 Mbps kufika ku-400 m
- I-serialized MAC ikheli eliyingqayizivele
- I-antenna ye-PCB ehlanganisiwe
- Isitifiketi sokulawulwa komsakazo e-US, Canada, Europe naseJapan
- I-Wi-Fi iqinisekisiwe
- Usayizi omncane we-PCB wemiklamo evumelana nezimo 1.7“ × 1.0” (4.3 cm × 2.0 cm)
- Isixhumi se-Pmod esinamaphini angu-12 esisebenzisana ne-SPI
- Ilandela I-Digilent Pmod Interface Specification Type 2A
- Imitapo yolwazi itholakala esikhungweni sezinsiza
Incazelo Esebenzayo
I-PmodWiFi inikeza usekelo lwe-IEEE 802.11b/g/n lwezinhlelo zokusebenza ezishumekiwe ngamanani edatha angu-1 no-2Mbps. Idizayinelwe ukusetshenziswa nemindeni ye-Microchip microcontroller (PIC18, PIC24, dsPIC33, nePIC32) kanye ne-Microchip TCP/IP Stack (ukulandwa kwamahhala kweLabhulali Yesicelo se-Microchip okuhlanganisa ne-ex.ample izicelo kanye nekhodi yomthombo). I-TCP/IP Stack iyatholakala ku- www.microchip.com/wireless.
Isixhumi esibonakalayo
Isixhumanisi esiyinhloko sokuxhumana ne-PmodWiFi ibhasi le-SPI. Iphinikhodi ye-RST ihlinzeka umsingathi ngokusethwa kabusha kwezingxenyekazi zekhompuyutha ezisebenzayo eziphansi ezisebenzayo ze-PmodWiFi. I-PmodWiFi futhi ihlinzeka ngephinikhodi esebenzayo yokuphazamiseka okuphansi (~INT), okuthiwa iphansi yi-PmodWifi uma idatha itholakala kudivayisi yomsingathi. Ulayini we-~INT akushiwo ukuthi uphakeme ngemva kokuqedwa kokudluliswa kwedatha. Isivinini se-SPI SCK singafika ku-25 MHz.

Incazelo yesignali yesixhumi esibonakalayo.
Izinga lesixhumi esibonakalayo se-SPI lisebenzisa imigqa yesignali emine. Lawa ukukhetha kwesigqila (~SS), master out slave in (MOSI), master in slave out (MISO), kanye newashi le-serial (SCK). Lawa masignali afaka imephu kumasiginali alandelayo ku-MRF24WB0MA: ~SS ihambisana nesiginali yokukhetha i-Chip (~CS), i-MOSI ihambisana nokufaka kwe-serial Data (SDI), i-MISO ihambisana nokuphuma kwedatha ye-serial (SDO), futhi i-SCK ihambisana ne-Serial Isignali yewashi (SCK).
Ukunikezwa kwamandla kagesi
- I-PmodWiFi yakhelwe ukuthi isebenze namabhodi e-Digilent microcontroller anezixhumi zezihloko ezingu-12.
- I-PmodWiFi idinga i-voltage engu-2.7V-3.6Vtage. Amandla kagesi angu-3.3VtagI-e itholakala kuwo wonke amabhodi esistimu ye-Digilent futhi inikezwa njengengxenye yezinga lokusebenzisana le-Pmod elinezintambo ezingu-12.
- Amabhodi esistimu e-Digilent anezixhumi zokuxhumanisa ze-Pmod avumela ukukhethwa kwe-jumper yevolthi yokunikezwa kwamandlatage inikezwa i-Pmod. Qinisekisa ukuthi ibhodi lesistimu liyagxuma ukuze linikeze i-3.3V kumojula ngaphambi kokufaka amandla ebhodini.
- Ukuze uthole ukwaziswa okwengeziwe nge-MRF24WB0MA, bheka imininingwane ye-MRF24WB0MA engafinyelelwa ku-Microchip's. webindawo.
