I-MIKROE-1985 USB I2C Chofoza
Ulwazi Lomkhiqizo
Ukuchofoza kwe-USB I2C ibhodi eliphethe i-MCP2221 USB-to-UART/I2C isiguquli sephrothokholi. Ivumela ukuxhumana ne-microcontroller eqondiwe ngokusebenzisa i-mikroBUS™ UART (RX, TX) noma i-I2C (SCL, SDA) interface. Ibhodi liphinde libe nezikhonkwane ezengeziwe ze-GPIO (GP0-GP3) kanye ne-I2C (SCL, SDA) kanye nokuxhumana kwe-VCC ne-GND. Isekela womabili amazinga e-logic ye-3.3V kanye ne-5V. I-chip ebhodini isekela i-USB enesivinini esigcwele (12 Mb/s), i-I2C enamazinga wewashi afika ku-400 kHz, kanye nezilinganiso ze-UART baud phakathi kuka-300 no-115200. Inebhayithi yebhayithi engu-128 yokuphuma kwedatha ye-USB futhi isekela kufika I-65,535-byte ubude Amabhulokhi Okufunda/Wokubhala okusetshenziswa kubonwa kwe-I2C. Ibhodi lihambisana nokucushwa kwe-Microchips kanye nezishayeli ze-Linux, Mac, Windows, ne-Android.
Imiyalo yokusetshenziswa komkhiqizo
- Ukuhlanganisa izihloko:
- Ngaphambi kokusebenzisa ibhodi lakho lokuchofoza, solder izihloko zabesilisa ezingu-1x8 kuzo zombili izinhlangothi zebhodi kwesokunxele nakwesokudla.
- Phendula ibhodi ulibhekise phansi ukuze uhlangothi olungezansi lubheke phezulu.
- Beka izikhonkwane ezimfushane zesihloko kumaphedi afanele.
- Phendula ibhodi phezulu futhi futhi uqondanise izihloko perpendicularly ebhodini.
- Solder ngokucophelela izikhonkwane.
- Ukuxhuma ibhodi:
- Uma usuwadayisile izihloko, ibhodi lakho selilungele ukufakwa kusokhethi oyifunayo ye-mikroBUS™.
- Qondanisa ukusika engxenyeni engezansi kwesokudla yebhodi kanye nezimpawu kusikrini sikasilika kusokhethi ye-mikroBUS™.
- Uma zonke izikhonkwane ziqondaniswe ngendlela efanele, phusha ibhodi lingene kusokhethi.
- Ikhodi exampkancane:
- Ngemva kokuqeda amalungiselelo adingekayo, landa ikhodi exampama-les we-mikroC™, mikroBasic™, kanye nama-mikroPascal™ compilers avela ku-Libstock webisayithi ukuze uqale ukusebenzisa ibhodi lakho lokuchofoza.
Isingeniso
Ukuchofoza kwe-USB I2C kuphethe isiguquli sephrothokholi ye-MCP2221 USB-to-UART/I2C. Ibhodi lixhumana nesilawuli esincane esiqondiwe ngokusebenzisa i-mikroBUS™ UART (RX, TX) noma i-I2C (SCL, SDA) yokuxhumana. Ngokungeziwe ku-mikroBUS™, imiphetho yebhodi ifakwe i-GPIO eyengeziwe (GP0-GP3) nezikhonkwane ze-I2C (SCL, SDA plus VCC kanye ne-GND). Ingasebenza kumazinga anengqondo angu-3.3V noma angu-5V.
Ukuhlanganisa izihloko
Ngaphambi kokusebenzisa ibhodi lokuchofoza™, qiniseka ukuthi uthengisa izihloko zabesilisa ezi-1x8 kuzo zombili izinhlangothi zebhodi kwesokunxele nakwesokudla. Izihloko ezimbili zabesilisa eziyi-1 × 8 zifakwe nebhodi ephaketheni.
Phendula ibhodi ulibhekise phansi ukuze uhlangothi olungezansi lubheke phezulu. Faka izikhonkwane ezimfushane zesihloko kumaphedi asodayo afanelekile.
Phendukisa ibhodi phezulu futhi. Qinisekisa ukuthi uqondanisa izihloko ukuze zibe perpendicular ebhodini, bese uthengisa izikhonkwane ngokucophelela.
Ixhuma ibhodi
Uma usuwadayisile izihloko ibhodi lakho selilungele ukufakwa kusokhethi osifunayo se-mikroBUS™. Qiniseka ukuthi uqondanisa ukusikwa engxenyeni engezansi kwesokudla yebhodi kanye nezimpawu kusikrini sikasilika kusokhethi ye-mikroBUS™. Uma zonke izikhonkwane ziqondaniswe ngendlela efanele, phusha ibhodi lingene kusokhethi.
Izici ezibalulekile
I-chip isekela i-USB enesivinini esigcwele (12 Mb/s), i-I2C ngezinga lewashi elingafika ku-400 kHz kanye namazinga e-UART baud aphakathi kuka-300 no-115200. I-USB ine-128-byte Buffer (64-Byte Transmit kanye ne-64-byte Receive) isekela ukuphuma kwedatha kunoma yimaphi lawo mazinga e-baud. I-interface ye-I2C isekela ama-Blocks afinyelela ku-65,535-byte amade Okufunda/Ukubhala. Ibhodi liphinde lisekelwe nezinsiza zokucushwa ze-Microchip nezishayeli ze-Linux, Mac, Windows ne-Android.
