MIKROE-1985 USB I2C Nyem

Cov ntaub ntawv khoom

USB I2C nyem yog lub rooj tsavxwm uas nqa MCP2221 USB-to-UART/I2C raws tu qauv converter. Nws tso cai rau kev sib txuas lus nrog lub hom phiaj microcontroller los ntawm mikroBUS ™ UART (RX, TX) lossis I2C (SCL, SDA) interfaces. Lub Rooj Tswjhwm Saib kuj tseem muaj ntxiv GPIO (GP0-GP3) thiab I2C pins (SCL, SDA) nrog rau kev sib txuas VCC thiab GND. Nws txhawb nqa 3.3V thiab 5V logic theem. Lub nti ntawm lub rooj tsavxwm txhawb nqa tag nrho-ceev USB (12 Mb / s), I2C nrog moos tus nqi mus txog 400 kHz, thiab UART baud tus nqi ntawm 300 thiab 115200. Nws muaj 128-byte tsis rau USB cov ntaub ntawv throughput thiab txhawb nqa mus txog rau 65,535-byte ntev Nyeem / Sau Blocks rau I2C interface. Lub Rooj Tswjhwm Saib tau sib xws nrog Microchip qhov kev teeb tsa kev siv hluav taws xob thiab cov tsav tsheb rau Linux, Mac, Windows, thiab Android.

Cov lus qhia siv khoom

1. Soldering cov headers:
   • Ua ntej siv koj lub rooj tsavxwm nyem, solder 1 × 8 txiv neej headers rau ob sab laug thiab sab xis ntawm lub rooj tsavxwm.
   • Tig lub board upside down kom lub sab hauv qab yog tig upwards.
   • Muab cov pins luv ntawm lub taub hau rau hauv cov ntaub so ntswg uas tsim nyog.
   • Tig lub rooj tsavxwm rov qab thiab kho cov headers perpendicularly rau lub rooj tsavxwm.
   • Ua tib zoo solder cov pins.
2. Txuas lub board rau hauv:
   • Thaum koj tau soldered lub headers, koj lub rooj tsavxwm npaj tau muab tso rau hauv lub qhov xav tau mikroBUS ™.
   • Teem qhov kev txiav nyob rau hauv qis-txoj cai ntawm lub rooj tsavxwm nrog cov cim ntawm lub silkscreen ntawm mikroBUS ™ socket.
   • Yog hais tias tag nrho cov pins raug ua kom raug, thawb lub rooj tsavxwm mus rau hauv lub qhov (socket).
3. Code examples:
   • Tom qab ua tiav cov kev npaj tsim nyog, rub tawm code examples rau mikroC™, mikroBasic™, thiab mikroPascal™ compilers los ntawm Libstock website pib siv koj nias board.

Taw qhia

USB I2C nyem yog ib qho MCP2221 USB-to-UART/I2C raws tu qauv converter. Lub rooj sib tham nrog lub hom phiaj microcontroller los ntawm mikroBUS ™ UART (RX, TX) lossis I2C (SCL, SDA) interfaces. Ntxiv rau mikroBUS ™, cov npoo ntawm lub rooj tsavxwm yog lined nrog ntxiv GPIO (GP0-GP3) thiab I2C pins (SCL, SDA ntxiv rau VCC thiab GND). Nws tuaj yeem ua haujlwm ntawm 3.3V lossis 5V logic theem.

Soldering cov headers

Ua ntej siv koj lub rooj tsavxwm nyem ™, nco ntsoov solder 1 × 8 txiv neej headers rau ob sab laug thiab sab xis ntawm lub rooj tsavxwm. Ob 1 × 8 txiv neej headers suav nrog lub rooj tsavxwm hauv pob.

Tig lub rooj tsavxwm upside down kom lub sab hauv qab yog tig koj upwards. Muab cov pins luv ntawm lub taub hau rau hauv cov ntaub so ntswg uas tsim nyog.

Tig lub rooj tsavxwm dua. Nco ntsoov kho cov headers kom lawv nyob rau ntawm lub rooj tsavxwm, ces solder cov pins kom zoo zoo.Plug lub rooj tsavxwm
Thaum koj tau soldered lub headers koj lub rooj tsavxwm yog npaj rau muab tso rau hauv lub siab xav mikroBUS ™ socket. Nco ntsoov ua kom cov kev txiav nyob rau hauv qis-txoj cai ntawm lub rooj tsavxwm nrog cov cim ntawm lub silkscreen ntawm lub qhov (socket) mikroBUS™. Yog hais tias tag nrho cov pins raug ua kom raug, thawb lub rooj tsavxwm mus rau hauv lub qhov (socket).

Cov yam ntxwv tseem ceeb

Lub nti txhawb nqa tag nrho-ceev USB (12 Mb / s), I2C nrog mus txog 400 kHz moos tus nqi thiab UART baud tus nqi ntawm 300 thiab 115200. Lub USB muaj 128-byte Buffer (64-Byte Transmit thiab 64-byte Txais) txhawb cov ntaub ntawv throughput ntawm ib qho ntawm cov baud tus nqi. I2C interface txhawb nqa txog 65,535-byte ntev nyeem / Sau Blocks. Lub Rooj Tswjhwm Saib kuj tau txais kev txhawb nqa nrog Microchip cov khoom siv hluav taws xob thiab cov tsav tsheb rau Linux, Mac, Windows thiab Android.
