Isekhethi

3.1. Uhlelo
I-WizFi360 inomjikelezo olula kakhulu. Ungakwazi ukuxhuma amandla ku-WizFi360 futhi uthumele futhi wamukele idatha nge-UART1. Futhi kufanele unake izikhonkwane ezine.

I-WIZnet WizFi360 Hardware Design - Ireferensi SchematicUmfanekiso 6. I-Reference Schematic

  • Setha kabusha
    Setha kabusha ukunikezwa kwesekethe ukuklama ngesekethe ye-RC. I-WizFi360 isetha kabusha ngokuzenzakalelayo ngamandla aphansi. Uma iphinikhodi ye-RESET ilawulwa isekethe yangaphandle, i-WizFi360 izosetha kabusha lapho ileveli ingaphansi kuka-2.0V.
    Izinga eliphansi lidinga ukuhlala ngaphezu kuka-100µs.
  • PA0
    Isekethe ye-PA0 inikeza ukuklama ukudonsa okungu-10k. I-PA0 isetshenziswa njengephinikhodi yokuqalisa, kodwa cishe akunakwenzeka kubasebenzisi abavamile. Leli phini lisetshenziswa efektritage. (Ukukhiqizwa kwemojuli)
  • PA1
    Isekethe ye-PA1 inikeza ukuklama ukudonsa okungu-10k. Uma i-PA1 Iphansi imizuzwana engu-3, ​​ipharamitha yamanje ye-UART1 ishintsha ibe yinani elimisiwe (sicela ubhekisele kumyalo we-AT+UART_CUR kumanuwali womyalo we-WizFi360 AT).
  • WP
    Isifunda se-WP sinikeza ukuklama ukucushwa komsebenzisi. Kufanele ulawule le phinikhodi uma usebenzisa imodi yokulinda. Uma le phinikhodi iphezulu kumodi yokulinda, i-WizFi360 isethwa kabusha kumodi yokusebenza evamile.

3.2. Amandla
I-WizFi360 idinga ukusetshenziswa kwamandla kagesi akwazi ukuhlinzeka ngo-3.0V kuya ku-3.6V nangaphezulu kuka-500mA. Ngenxa yokuthi i-WizFi360 isebenza ngokujwayelekile ukusuka ku-3.0V ukuya ku-3.6V, idla kufika ku-230mA wamanje osheshayo. Ububanzi bezintambo akufanele bube ngaphansi kuka-30mil.
I-capacitor yokuqinisa amandla (100nF) kufanele ibekwe eduze nephinikhodi ye-VCC.
3.3. UART

I-WIZnet WizFi360 Hardware Design - UARTUmfanekiso 7. UART

  • UART1
    I-UART1 iyi-UART yokuxhumana eyinhloko. Ukuxhumana komyalo we-AT kungenzeka nge-UART1 futhi ukuxhumana kwedatha kungenzeka.
  • UART0
    I-UART0 ayitholakali kubasebenzisi abajwayelekile. Le UART isetshenziswa efekthritage (Ukukhiqizwa kwemojula) futhi kuhloselwe abathuthukisi be-firmware bangaphakathi be-WizFi360.

3.4. SPI
I-WizFi360 isekela imodi yokuxhumana ye-SPI. Uma amandla avuliwe noma asethwa kabusha, Uma iphinikhodi ye-PB13(SPI_EN) ihlala iphansi, isebenza ngemodi yokuxhumana ye-SPI.

3.5. ETC
Le seshini iyigayidi yesekethe eyengeziwe yokusebenzisa i-WizFi360. Akumele ugcine lesi sikhathi. Kodwa uma uyidinga, uyayiklama.

  • I-UART Flow Control
    Uma ufuna ukusebenzisa i-UART Flow Control, udinga ukudizayina isekethe njengoba kukhonjisiwe kuMfanekiso 3. I-PB9 yi-CTS1, i-PB10 iyi-RTS1.I-WIZnet WizFi360 I-Hardware Design - Ukulawula Ukugeleza kwe-UARTUmfanekiso 9. I-UART Flow Control
  • UART Level Shifter
    I-UART voltagI-e ku-WizFi360 ingu-3.3V. Nokho, i-MCU yakho ingase ingabi nayo ivolumutagkwe 3.3v. Uma kunjalo udinga i-Level Shifter ukuze uxhume i-WizFi360 ku-MCU yakho. Ungadizayina isekethe ye-Level Shifter ngokubhekisela kuMfanekiso 4. Xhuma ivolumu ye-UART ye-MCU yakhotage ku-VCCIO ku-Figure 4.

Isakhiwo se-PCB

  • Ububanzi bezintambo zamandla akufanele bube ngaphansi kuka-30mil.
  • Ngaphandle kwengxenye ye-antenna ye-WizFi360, ungqimba olungezansi lwesihlangu kufanele lube nendiza ye-GND.I-WIZnet WizFi360 Hardware Design - GNDUmfanekiso 12. GND
  • Amanani. 6 kanye nezibalo. 7 kukhona ukubekwa kwezimpondo ezi-2 okungasebenza kahle kakhulu uthi. Siphakamisa ukuthi amakhasimende akhethe eyodwa yalezi zindlela ezi-2 ukuze adizayine ukubekwa. Ngemodi yesibili yokubeka, uthi lwe-PCB kufanele okungenani lube ngu-5.0mm ukusuka ezinhlangothini zombili zebhodi elingezansi.
