MIKROE-1985 USB I2C Cofa

Ulwazi lweMveliso

Ukucofa kwe-USB I2C yibhodi ethwala i-MCP2221 USB-to-UART/I2C isiguquli seprotocol. Ivumela unxibelelwano kunye ne-microcontroller ekujoliswe kuyo ngokusebenzisa i-mikroBUS™ UART (RX, TX) okanye i-I2C (SCL, SDA) ujongano. Ibhodi iphinda ibonise i-GPIO eyongezelelweyo (GP0-GP3) kunye ne-I2C izikhonkwane (i-SCL, i-SDA) kunye ne-VCC kunye ne-GND uxhumano. Ixhasa zombini i-3.3V kunye ne-5V amanqanaba engqiqo. Itshiphu ebhodini ixhasa i-USB egcwele isantya (i-12 Mb/s), i-I2C enamazinga ewotshi ukuya kuthi ga kwi-400 kHz, kunye namazinga e-UART baud phakathi kwe-300 kunye ne-115200. I-128-byte ubude beebhloko eziFundayo/zoBhala kwi-interface ye-I65,535C. Ibhodi iyahambelana nesixhobo soqwalaselo seMicrochip kunye nabaqhubi beLinux, Mac, Windows, kunye ne-Android.

Imiyalelo yokusetyenziswa kwemveliso

1. Ukuthengisa iiheader:
   • Ngaphambi kokusebenzisa ibhodi yakho yokucofa, solder 1 × 8 iiheader zamadoda kumacala omabini asekhohlo nasekunene ebhodi.
   • Jika ibhodi ijonge phantsi ukuze icala elisezantsi lijonge phezulu.
   • Beka izikhonkwane ezimfutshane zentloko kwiipads ezifanelekileyo ze-soldering.
   • Jika ibhodi phezulu kwakhona kwaye ulungelelanise iiheader ngokuthe ngqo ebhodini.
   • Ngononophelo solder izikhonkwane.
2. Ukuplaga ibhodi ngaphakathi:
   • Nje ukuba uthengise iiheader, ibhodi yakho ilungele ukubekwa kwisokethi ye-mikroBUS™ oyifunayo.
   • Lungelelanisa isikiweyo kwindawo esekunene esezantsi yebhodi kunye neempawu kwiscreen sesilika kwisokethi ye-mikroBUS™.
   • Ukuba zonke izikhonkwane zilungelelaniswe ngokuchanekileyo, tyhala ibhodi yonke indlela ukuya kwisokethi.
3. Ikhowudi exampngaphantsi:
   • Emva kokugqiba amalungiselelo ayimfuneko, khuphela ikhowudi exampiiles zemikroC™, mikroBasic™, kunye nabaqokeleli bemikroPascal™ abavela kwiLibstock webindawo ukuqala ukusebenzisa ibhodi yakho yokucofa.

Intshayelelo

Ukucofa i-USB I2C ithwala i-MCP2221 USB-to-UART/I2C iprotocol converter. Ibhodi inxibelelana ne-microcontroller ekujoliswe kuyo ngokusebenzisa i-mikroBUS™ UART (RX, TX) okanye i-I2C (SCL, SDA) ujongano. Ukongeza kwi-mikroBUS™, imiphetho yebhodi ifakwe kwi-GPIO eyongezelelweyo (GP0-GP3) kunye nezikhonkwane ze-I2C (SCL, SDA plus VCC kunye ne-GND). Iyakwazi ukusebenza kumanqanaba logic 3.3V okanye 5V.

Ukuthengisa iiheader

Ngaphambi kokusebenzisa ibhodi yakho yokucofa, qiniseka ukuba uthengisa i-1 × 8 iiheader zamadoda ukuya ngasekhohlo nasekunene kwebhodi. Iintloko ezimbini ze-1 × 8 zamadoda zifakwe kunye nebhodi kwiphakheji.

Jika ibhodi ijonge phantsi ukuze icala elisezantsi lijonge kuwe phezulu. Beka izikhonkwane ezimfutshane zentloko kwiipads ezifanelekileyo ze-soldering.

Yijike ibhodi iye phezulu kwakhona. Qinisekisa ukuba ulungelelanisa iintloko ukwenzela ukuba zihambelane nebhodi, uze uthengise izikhonkwane ngononophelo.Ukuplaga ibhodi
Nje ukuba uthengise iiheader ibhodi yakho ilungele ukubekwa kwisokethi ye-mikroBUS™ oyifunayo. Qinisekisa ukuba ulungelelanisa isisikwa kwindawo esekunene esezantsi yebhodi kunye neempawu kwiscreen sesilika kwisokethi ye-mikroBUS™. Ukuba zonke izikhonkwane zilungelelaniswe ngokuchanekileyo, tyhala ibhodi yonke indlela ukuya kwisokethi.

Iimpawu ezibalulekileyo

I-chip ixhasa i-USB egcwele isantya esiphezulu (i-12 Mb / s), i-I2C ukuya kuthi ga kwi-400 kHz amazinga ewotshi kunye namazinga e-UART baud phakathi kwe-300 kunye ne-115200. I-USB ine-128-byte Buffer (i-64-Byte Transmit kunye ne-64-byte Yamkela) ukuxhasa ugqithiso lwedatha kuyo nayiphi na loo mazinga e-baud. I-interface ye-I2C ixhasa ukuya kuthi ga kwi-65,535-byte ende yokufunda/uBhala iibhloko. Ibhodi ikwaxhaswa kunye ne-Microchip's configuration utility kunye nabaqhubi beLinux, Mac, Windows kunye ne-Android.

Iiseti ezimbini zeejumpi ze-SMD

I-GP SEL yeyokucacisa ukuba ngaba i-GPO I/Os iyakuqhagamshelwa kwipinout, okanye isetyenziswe ukunika amandla umqondiso we-LEDs. Iijumpi ze-I/O LEVEL zezokutshintsha phakathi kwe-3.3V okanye i-5V logic.

Ikhowudi exampLes

Nje ukuba wenze onke amalungiselelo ayimfuneko, lixesha lokufumana ibhodi yakho yokucofa™ kwaye isebenze. Sibonelele exampiiles zemikroC™, mikroBasic™, kunye nabaqokeleli bemikroPascal™ kwiLibstock yethu webindawo. Zikhuphele nje kwaye ulungele ukuqalisa.
