Litaelo tsa Tšebeliso ea Sehlahisoa
Tlhaloso ea Mosebetsi:
PmodWiFi e fana ka tšehetso ea IEEE 802.11b/g/n bakeng sa lits'ebetso tse kentsoeng ka litefiso tsa data tsa 1 le 2Mbps. E etselitsoe ho sebelisoa le malapa a microchip microcontroller (PIC18, PIC24, dsPIC33, le PIC32) le Microchip TCP / IP Stack.
1.1 Sehokelo:
Khokahano ea mantlha ea puisano le PmodWiFi ke bese ea SPI. PmodWiFi e boetse e fana ka pin e sebetsang e tlase ea tšitiso (~INT) le phini ea RST bakeng sa ho seta botjha ha hardware.
Pinout ea Sehokelo sa Sehokelo:
| Pin | Letshwao | Tlhaloso |
|---|---|---|
| 1 | ~SS | Khetha Makhoba |
| 2 | MOSI | Master out/Lekhoba ho Lintlha |
| 3 | MISO | Master in/Slave out Data |
| 4 | TS'ELISO | Seriba oache |
| 5 | GND | Sebaka sa Phepelo ea Matla |
| 6 | VCC | Phepelo ea Matla (3.3V) |
| 7 | ~INT | Khatisa Sephetho |
| 8 | ~RST | Hardware Reset |
| 9 | ~WP | Ngola Sireletsa |
| 10 | HIB | Hibernate |
| 11 | GND | Sebaka sa Phepelo ea Matla |
| 12 | VCC | Phepelo ea Matla (3.3V) |
Phepelo ea motlakase:
PmodWiFi e hloka motlakase oa 2.7V-3.6Vtage. Matla a matla a 3.3Vtage e fumaneha libotong tsohle tsa tsamaiso ea Digilent 'me e fanoa e le karolo ea 12-wire Pmod interface standard. Netefatsa hore boto ea sistimi e tlositsoe ho fana ka 3.3V ho module pele o sebelisa matla ho boto.
Ho fumana lintlha tse ling, sheba database ea MRF24WB0MA e fumanehang ho Microchip's websebaka.
Fetileview
PmodWiFi e fana ka phihlello ea Wi-Fi ka module ea transceiver ea radio ea Microchip® MRF24WG0MA Wi-Fi™. Basebelisi ba ka buisana le chip e lumellanang le IEEE 802.11g ka SPI le ho fihlela litefiso tsa data ho fihla ho 54 Mbps.
Likarolo li kenyelletsa:
- IEEE 802.11-e lumellanang le RF transceiver
- Romella lintlha ho 1 le 2 Mbps ho fihla ho 400 m
- E hlophisitsoe ka aterese e ikhethang ea MAC
- Antenna ea PCB e kopantsoeng
- Setifikeiti sa taolo ea seea-le-moea bakeng sa US, Canada, Europe le Japane
- Wi-Fi e netefalitsoe
- PCB e nyane bakeng sa meralo e tenyetsehang 1.7“ × 1.0” (4.3 cm × 2.0 cm)
- Sehokelo sa 12-pin Pmod se nang le sebopeho sa SPI
- E latela Digilent Pmod Interface Specification Type 2A
- Lilaebrari li fumaneha setsing sa lisebelisoa
Tlhaloso ea Ts'ebetso
PmodWiFi e fana ka tšehetso ea IEEE 802.11b/g/n bakeng sa lits'ebetso tse kentsoeng ka litefiso tsa data tsa 1 le 2Mbps. E etselitsoe ho sebelisoa le malapa a microchip microcontroller (PIC18, PIC24, dsPIC33, le PIC32) le Microchip TCP/IP Stack (ho jarolleloa mahala ho li-Libraries tsa kopo ea Microchip ho kenyelletsa le ex.ample lits'ebetso le khoutu ea mohloli). TCP/IP Stack e fumaneha ho www.microchip.com/wireless.
Sehokedi
Khokahano ea mantlha ea puisano le PmodWiFi ke bese ea SPI. Pini ea RST e fa moamoheli sesebelisoa se tlase se sebetsang, se sa ts'oaneng le sa PmodWiFi. PmodWiFi e boetse e fana ka pin e sebetsang e tlase ea tšitiso (~INT), e boleloang e le tlase ke PmodWifi ha data e fumaneha bakeng sa sesebelisoa sa moamoheli. Mohala oa ~INT ha o khothalletsoe holimo ka mor'a hore phetiso ea data e phetheloe. Lebelo la SPI SCK le ka fihla ho 25 MHz.

Tlhaloso ea lets'oao la sehokelo.
Tekanyetso ea sebopeho sa SPI e sebelisa mela e mene ea matšoao. Tsena ke khetho ea makhoba (~SS), master out lekhoba ho (MOSI), master in slave out (MISO), le serial clock (SCK). Matshwao ana a matshwao a matshwao a latelang ho MRF24WB0MA: ~SS e dumellana le letshwao la Chip Select (~CS), MOSI e tsamaisana le Serial Data Input (SDI), MISO e tsamaisana le Serial Data Output (SDO), mme SCK e tsamaisana le Serial Letšoao la oache (SCK).
Phepelo ea motlakase
- PmodWiFi e etselitsoe ho sebetsa le liboto tsa Digilent microcontroller tse nang le likhokahano tsa lihlooho tse 12.
- PmodWiFi e hloka motlakase oa 2.7V-3.6Vtage. Matla a matla a 3.3Vtage e fumaneha libotong tsohle tsa tsamaiso ea Digilent 'me e fanoa e le karolo ea 12-wire Pmod interface standard.
- Liboto tsa tsamaiso ea Digilent tse nang le li-interface tsa Pmod li lumella khetho ea jumper ea matla a phepelo ea matlatage fuoa Pmod. Netefatsa hore boto ea sistimi e tlositsoe ho fana ka 3.3V ho module pele o sebelisa matla ho boto.
- Bakeng sa tlhaiso-leseling e batsi ka MRF24WB0MA, bona database ea MRF24WB0MA e ka fumanehang ho Microchip's. websebaka.
