MIKROE-1985 USB I2C Dinani

Zambiri Zamalonda

Kudina kwa USB I2C ndi bolodi yomwe imanyamula chosinthira protocol cha MCP2221 USB-to-UART/I2C. Imalola kulumikizana ndi chowongolera chowongolera kudzera pa mikroBUS™ UART (RX, TX) kapena I2C (SCL, SDA) yolumikizirana. Bungweli lilinso ndi ma GPIO (GP0-GP3) ndi ma I2C owonjezera (SCL, SDA) pamodzi ndi ma VCC ndi GND. Imathandizira onse 3.3V ndi 5V logic levels. Chip pa bolodi chimathandizira USB yothamanga (12 Mb / s), I2C yokhala ndi mawotchi mpaka 400 kHz, ndi mitengo ya UART baud pakati pa 300 ndi 115200. Ili ndi buffer ya 128-byte ya USB data throughput ndipo imathandizira mpaka 65,535-byte kutalika kwa Kuwerenga/Kulemba Ma block a mawonekedwe a I2C. Bungweli limagwirizana ndi makonzedwe a Microchip ndi madalaivala a Linux, Mac, Windows, ndi Android.

Malangizo Ogwiritsira Ntchito Zogulitsa

1. Kugulitsa mitu:
   • Musanagwiritse ntchito bolodi lanu, solder 1 × 8 mitu yamphongo kumanzere ndi kumanja kwa bolodi.
   • Tembenuzirani bolodi mozondoka kuti mbali ya pansi iyang'ane mmwamba.
   • Ikani zikhomo zazifupi za mutu muzitsulo zoyenera zogulitsira.
   • Tembenuzirani bolodi m'mwamba kachiwiri ndikuyanjanitsa mituyo molunjika ku bolodi.
   • Mosamala solder zikhomo.
2. Kulumikiza board mu:
   • Mukagulitsa mitu, bolodi lanu lakonzeka kuyikidwa mu socket yomwe mukufuna ya mikroBUS™.
   • Gwirizanitsani odulidwa kumunsi kumanja kwa bolodi ndi zolembera pa silkscreen pa socket ya mikroBUS™.
   • Ngati mapini onse alumikizidwa bwino, kanikizani bolodi mpaka muzitsulo.
3. Kodi exampzochepa:
   • Mukamaliza kukonzekera kofunikira, tsitsani code examples for mikroC™, mikroBasic™, ndi mikroPascal™ compilers kuchokera ku Libstock webtsamba kuti muyambe kugwiritsa ntchito bolodi lanu lodina.

Mawu Oyamba

Kudina kwa USB I2C kumanyamula chosinthira cha protocol cha MCP2221 USB-to-UART/I2C. Bolodi imalumikizana ndi chowongolera chowongolera kudzera pa mikroBUS™ UART (RX, TX) kapena I2C (SCL, SDA). Kuphatikiza pa mikroBUS™, m'mphepete mwa bolodi mulinso ma GPIO (GP0-GP3) ndi ma I2C (SCL, SDA kuphatikiza VCC ndi GND). Itha kugwira ntchito pamlingo wa 3.3V kapena 5V logic.

Kugulitsa ma headers

Musanagwiritse ntchito dinani board ™, onetsetsani kuti mwagulitsa mitu yachimuna 1 × 8 kumanzere ndi kumanja kwa bolodi. Mitu iwiri yachimuna 1 × 8 ikuphatikizidwa ndi bolodi mu phukusi.

Tembenuzirani bolodi mozondoka kuti mbali ya pansi ikuyang'anireni mmwamba. Ikani zikhomo zazifupi zamutu pazitsulo zoyenera.

Tembenuzirani bolodi m'mwamba kachiwiri. Onetsetsani kuti mwagwirizanitsa mitu kuti ikhale yozungulira pa bolodi, ndiyeno gulitsani zikhomozo mosamala.Kulumikiza board mkati
Mukagulitsa mitu bolodi yanu yakonzeka kuyikidwa mu socket yomwe mukufuna ya mikroBUS™. Onetsetsani kuti mwalumikiza chodulidwa kumunsi chakumanja kwa bolodi ndi zolembera pa silkscreen pa socket ya mikroBUS™. Ngati mapini onse alumikizidwa bwino, kanikizani bolodi mpaka muzitsulo.

Zofunikira

Chip imathandizira USB yothamanga kwambiri (12 Mb/s), I2C yokhala ndi mawotchi ofikira 400 kHz ndi mitengo ya baud ya UART pakati pa 300 ndi 115200. USB ili ndi Buffer ya 128-byte (64-Byte Transmit ndi 64-byte Receive) kuthandizira kutulutsa kwa data pamtundu uliwonse wa baud. Mawonekedwe a I2C amathandizira mpaka 65,535-byte yaitali Kuwerenga/Kulemba Blocks. Bolodiyi imathandizidwanso ndi makonzedwe a Microchip ndi madalaivala a Linux, Mac, Windows ndi Android.

Ma seti awiri a SMD jumpers

GP SEL ndi yofotokoza ngati GPO I/Os ilumikizidwa ku pinout, kapena kugwiritsidwa ntchito popatsa mphamvu ma LED. I/O LEVEL jumpers ndi yosinthira pakati pa 3.3V kapena 5V logic.

Kodi examples

Mukamaliza kukonzekera zonse zofunika, ndi nthawi yoti muyambe kugwira ntchito. Tapereka kaleamples for mikroC™, mikroBasic™, ndi mikroPascal™ compilers pa Libstock yathu webmalo. Basi kukopera iwo ndipo ndinu okonzeka kuyamba.

Thandizo

MicroElektronika imapereka chithandizo chaulere chaukadaulo (www.microe.com/support) mpaka mapeto a moyo wa mankhwala, kotero ngati chinachake chilakwika, ndife okonzeka ndi okonzeka kuthandiza!
