1. Isingeniso
Le ncwadi inikeza ulwazi olubalulekile lokusetshenziswa, ukufakwa, kanye nokugcinwa okufanele kwe-MICROCHIP MCP2200-I/SO USB to UART Serial Converter. I-MCP2200 iyisekethe ehlanganiswe kakhulu eyenzelwe ukunikeza ikhambi elilula nelingabizi kakhulu lokwengeza ukuxhumana kwe-USB ezinhlelweni ezivame ukusebenzisa ukuxhumana kwe-UART (Universal Asynchronous Receiver/Transmitter).
Izici ezibalulekile zifaka:
- Izinga Ledatha: Kufika ku-12 Mbps (Isivinini Esigcwele se-USB)
- Inani Leziteshi: 8 (izikhonkwane ze-GPIO ezilungisekayo zemisebenzi eyahlukahlukene)
- I-Supply Voltage: 2.7 V kuya ku-5.5 V
- Ibanga Lokushisa Elisebenzayo: -40 ° C kuye ku- + 85 ° C
- Iphakheji: SOIC-20LD (Ubuchwepheshe Bokuthayipha Okuphezulu)
2. Umkhiqizo Uphelileview
I-MCP2200-I/SO iyisekethe ehlanganisiwe ehlanganisiwe, ngokuvamile emnyama ngombala, enezikhonkwane zensimbi ezisuka ezinhlangothini zayo ukuze zifakwe ngaphezulu ebhodini lesekethe eliphrintiwe (i-PCB). Isebenza njengebhuloho, iguqula idatha phakathi kwesixhumi esibonakalayo se-USB kanye nesixhumi esibonakalayo esijwayelekile se-UART.
Umfanekiso 2.1: Isithombe esibonisa umzimba omnyama ongunxande wesekethe ehlanganisiwe ye-MCP2200-I/SO enezikhonkwane zensimbi ezisuka kuzo zombili izinhlangothi ezinde, ezenzelwe ukusetshenziswa kokufakwa kwendawo. Ukufakwa okuncane okuyisiyingi kuphawula iphini 1, okubonisa ukuqondiswa.
3. Ukusetha Nokuhlanganisa
I-MCP2200-I/SO iyisakhi esibekwa phezu kwendawo esidinga ukuhlanganiswa kwisekethe enkulu kagesi. Ukusethwa okufanele kuhilela:
- Umklamo we-PCB: Dala ibhodi lesifunda eliphrintiwe (i-PCB) elihambisana nephakheji ye-SOIC-20LD. Qinisekisa ukuthi amaphini anikezwa ngendlela efanele ye-USB (D+, D-), i-UART (TX, RX), amandla (i-VCC, i-GND), kanye nanoma yikuphi ukusebenza kwe-GPIO okufiswayo. Bheka ishidi ledatha elisemthethweni le-Microchip ukuze uthole amaphini anemininingwane kanye nemidwebo yesifunda enconyiwe.
- Ukunikezwa kwamandla kagesi: Nikeza ugesi ozinzile ngaphakathi kobubanzi obubekiwe obungu-2.7 V kuya ku-5.5 V. Kunconywa ama-capacitor okususa ugesi eduze kwamaphini e-VCC ukuqinisekisa ukusebenza okuzinzile.
- Uxhumano lwe-USB: Xhuma amaphini e-USB D+ kanye ne-D- kusixhumi se-USB esijwayelekile (isb., i-USB Type-B noma i-Micro-USB) ku-PCB yakho. Ama-resistors angaphandle angadingeka kuye ngokucushwa kwe-USB host.
- Uxhumano lwe-UART: Xhuma izikhonkwane ze-UART TX kanye ne-RX esibonakalayo se-UART esihambisanayo se-microcontroller noma idivayisi yakho eqondiwe. Qinisekisa ukuthi i-voltagukuhambisana kwezinga le-e.
- Ukufakwa komshayeli: Uma ihadiwe isihlanganisiwe futhi ixhunywe kukhompyutha nge-USB, abashayeli abadingekayo be-MCP2200 bazofakwa ngokuzenzakalelayo yizinhlelo zokusebenza zesimanje. Uma kungenjalo, abashayeli bangalandwa ku-Microchip esemthethweni. webindawo.
Qaphela: Le divayisi yenzelwe ukuhlanganiswa onjiniyela be-elekthronikhi abanolwazi. Bheka ishidi ledatha eliphelele ukuthola izici zikagesi ezinemininingwane kanye namanothi okusetshenziswa.
4. Ukusebenza
Uma i-MCP2200-I/SO isihlanganiswe kahle kwisekethe futhi ixhunywe kwikhompyutha ephethe nge-USB, izobalwa njengechweba elijwayelekile le-COM. Lokhu kuvumela izinhlelo zokusebenza zesofthiwe kukhompyutha ephethe ukuthi zixhumane nedivayisi ye-UART exhunywe kumaphini ochungechunge e-MCP2200.
- Ukuxhumana kwe-Serial: Sebenzisa noma yiluphi uhlelo olujwayelekile lwe-serial terminal (isb., i-PuTTY, i-Tera Term, i-Arduino Serial Monitor) noma isofthiwe yangokwezifiso ukuvula i-virtual COM port ehlotshaniswa ne-MCP2200.
- Ukucushwa kwe-Baud Rate: Lungiselela izinga le-baud, ama-data bits, i-parity, kanye nama-stop bits kusofthiwe yakho ukuze ifane nezilungiselelo zedivayisi ye-UART exhunywe ku-MCP2200. I-MCP2200 isekela amazinga avamile e-baud.
- Ukugeleza Kwedatha: Idatha ethunyelwe kusuka kukhompyutha ephethe i-comp iye ku-virtual COM port izoguqulwa yi-MCP2200 bese idluliselwa ngephinikhodi yayo ye-UART TX. Idatha etholwe kuphinikhodi ye-UART RX izoguqulwa bese ithunyelwa emuva kukhompyutha ephethe i-USB.
- Ukulawulwa kwe-GPIO: I-MCP2200 iphinde ibe namaphini angu-8 e-General Purpose Input/Output (GPIO). Lawa angalungiswa futhi alawulwe ngemiyalo ethile ye-USB noma nge-utility enikezelwe yi-Microchip, okuvumela ukulawula okwengeziwe kudivayisi exhunyiwe.
5. Isondlo Nokunakekela
I-MCP2200-I/SO iyisekethe ehlanganisiwe eqinile eyenzelwe ukusebenza isikhathi eside. Kudingeka ukulungiswa okuncane, kodwa ukunamathela eziqondisweni ezilandelayo kuzoqinisekisa ukusebenza kahle kanye nobude besikhathi:
- Izimo Zemvelo: Sebenzisa idivayisi ngaphakathi kwebanga layo lokushisa lokusebenza elibekiwe (-40°C kuya ku-+85°C) futhi ugweme ukuchayeka emswakama owedlulele, uthuli, noma izinto ezibolayo.
- Ukuqina Kokuhlinzeka Ngamandla: Qinisekisa ukuthi ugesi uhlanzekile futhi uzinzile.tagukushintshashintsha noma ukuguquguquka ngokweqiletagkungalimaza ingxenye.
- Ukuphatha ngokomzimba: Phatha i-IC ngokucophelela ngesikhathi sokuhlanganiswa ukuze uvimbele umonakalo kumaphini noma ephaketheni. Sebenzisa izinyathelo zokuphepha ezilwa nokungaguquguquki lapho usebenza ngezingxenye ze-elekthronikhi.
- Ukuhlanza: Uma kudingeka ukuhlanza, sebenzisa ibhulashi elithambile nelomile noma umoya ocindezelwe ukuze ususe uthuli. Gwema izihlanzi zoketshezi ngaphandle uma zenzelwe ngqo izinto zikagesi futhi zisetshenziswa kancane.
