MIKROE-1985 USB I2C Tobetsa

Tlhahisoleseding ya Sehlahiswa

Tobetsa USB I2C ke boto e nang le MCP2221 USB-to-UART/I2C protocol converter. E lumella puisano le microcontroller e shebiloeng ka li-interface tsa mikroBUS™ UART (RX, TX) kapa I2C (SCL, SDA). Boto e boetse e na le lisebelisoa tse eketsehileng tsa GPIO (GP0-GP3) le I2C (SCL, SDA) hammoho le likhokahano tsa VCC le GND. E ts'ehetsa maemo a logic a 3.3V le 5V. Chip e holim'a boto e ts'ehetsa USB ea lebelo le felletseng (12 Mb/s), I2C e nang le lioache tse fihlang ho 400 kHz, le UART baud rates lipakeng tsa 300 le 115200. E na le buffer ea 128-byte bakeng sa phepelo ea data ea USB mme e ts'ehetsa ho fihla ho 65,535-byte bolelele ba li-Blocks/Writes Blocks bakeng sa I2C interface. Boto e lumellana le lisebelisoa tsa tlhophiso tsa Microchip le likhanni tsa Linux, Mac, Windows le Android.

Litaelo tsa Tšebeliso ea Sehlahisoa

1. Ho kopanya lihlooho:
   • Pele o sebelisa boto ea hau ea ho tobetsa, solder 1 × 8 lihlooho tsa banna ho ea ka lehlakoreng le letšehali le le letona la boto.
   • Fetolela boto e le hore lehlakore le ka tlase le shebe holimo.
   • Beha lithakhisa tse khutšoanyane tsa hlooho ka har'a liphahlo tse loketseng tsa solder.
   • Fetolela boto holimo hape 'me u tsamaise lihlooho ho ea ka boto.
   • Ka hloko solder lithakhisa.
2. Ho hokela boto:
   • Ha u se u rekisitse lihlooho, boto ea hau e se e loketse ho kenngoa ka har'a sokete e lakatsehang ea mikroBUS™.
   • Lokisetsa sehiloeng karolong e ka tlaase-ho le letona ea boto le matšoao a skrineng sa silika soketeng ea mikroBUS™.
   • Haeba lithapo tsohle li hokahane hantle, sutumelletsa boto ho ea fihla soketeng.
3. Khoutu examphanyane:
   • Kamora ho qeta litokisetso tse hlokahalang, download code examples bakeng sa likhokahano tsa mikroC™, mikroBasic™, le mikroPascal™ ho tsoa ho Libstock websaete ea ho qala ho sebelisa boto ea hau ea ho tobetsa.

Selelekela

Tobetsa USB I2C e na le converter ea protocol ea MCP2221 USB-to-UART/I2C. Boto e hokahana le microcontroller e shebiloeng ka li-interface tsa mikroBUS™ UART (RX, TX) kapa I2C (SCL, SDA). Ho phaella ho mikroBUS ™, likarolo tsa boto li na le GPIO e eketsehileng (GP0-GP3) le I2C pins (SCL, SDA plus VCC le GND). E ka sebetsa maemong a logic a 3.3V kapa 5V.

Ho kopanya lihlooho

Pele u sebelisa "click board" ea hau, etsa bonnete ba hore u rekisa lihlooho tsa banna tse 1 × 8 ka lehlakoreng le letšehali le le letona la boto. Lihlooho tse peli tsa banna ba 1 × 8 li kenyelelitsoe le boto ka har'a sephutheloana.

Fetolela boto e le hore lehlakore le ka tlase le shebane le uena holimo. Beha lithakhisa tse khutšoane tsa hlooho ka har'a lipache tse loketseng tsa solder.

Fetolela boto holimo hape. Etsa bonnete ba hore u hokahanya lihlooho e le hore li ka pota-potile boto, ebe u rekisa lithakhisa ka hloko.Ho hokela boto
Hang ha u se u rekisitse lihlooho boto ea hau e se e loketse ho kenngoa ka har'a sokete e lakatsehang ea mikroBUS™. Etsa bonnete ba hore o hokahanya sehiloeng karolong e ka tlaase-ho le letona ea boto le matšoao a skrineng sa silika soketeng ea mikroBUS™. Haeba lithapo tsohle li hokahane hantle, sutumelletsa boto ho ea fihla soketeng.

Likarolo tsa bohlokoa

Chip e ts'ehetsa USB ea lebelo le felletseng (12 Mb/s), I2C e nang le litekanyetso tsa oache tse fihlang ho 400 kHz le UART baud rates lipakeng tsa 300 le 115200. USB e na le 128-byte Buffer (64-Byte Transmit le 64-byte Receive) e tšehetsang phallo ea data ho efe kapa efe ea litefiso tseo tsa baud. Khokahano ea I2C e ts'ehetsa ho fihla ho 65,535-byte nako e telele ea Reads/Writes Blocks. Boto e boetse e tšehetsoa ka lisebelisoa tsa tlhophiso tsa Microchip le li-driver tsa Linux, Mac, Windows le Android.
