Raspberry Pi Pico: SBC qhov tshiab thiab pheej yig

Txiv Kab Ntxwv Pi Pico

Raspberry Pi Foundation tau tsim cov khoom tshiab. Nws txog qhov Txiv Kab Ntxwv Pi Pico, SBC pheej yig tshiab uas koom nrog cov uas twb muaj lawm. Nrog rau qhov ntawd, qhov kev pom zoo tam sim no yog qhov txhawb nqa, nrog rau Raspberry Pi 4 thiab Pi Zero, lossis Pi 400. Tam sim no, hom ntawv tshiab yog ntawm qhov txo me me, thiab nrog tus nqi tiag tiag: txog $ 4.

Qhov no nws yog a MCU lossis microcontroller, cov kev daws teeb meem yooj yim thiab txo qis los siv rau txhua yam tsim nyog los khiav lub cev sib xyaw thiab siv rau cov phiaj xwm qhov loj thiab kev noj haus tseem ceeb, xws li cov phiaj xwm kho mob, tsheb, kev lag luam, neeg hlau, huab cua, thiab lwm yam.

Tej zaum koj yuav xav tias qhov no tsis yog xov xwm zoo, thiab nws yog qhov tseeb tias cov phiajcim uas zoo sib xws twb muaj lawm. Tab sis zoo xov xwm yog lwm. Tus Raspberry Pi Foundation tau txais kev ceebCov. Thiab nws tshwm sim los ua cov neeg tsim qauv zoo ntawm nws tus kheej chips, xws li SoC tias nws suav nrog hauv Raspberry Pi Pico.

Ib sab SoC tsim los ntawm lawv tus kheej thiab npe tom qab RP2040Cov. Cov cores ua tsis tau tsim los ntawm kos, hloov peb xaiv rau cov ntawv pov thawj cores los ntawm Arm. Tshwj xeeb, ob lub ARM Cortex M0 + cores ntawm 133Mhz tau ua tiav. Nrog lawv, 264 KB ntawm RAM thiab 2MB ntawm flash cia tau siv, ntxiv rau PIO (Programmable I / O) ua haujlwm los cuam tshuam kev cuam tshuam xws li cov ntawm SD card, VGA, thiab lwm yam.

Saib kom paub! Vim tias lawv tsis tau dhau los ua IDM ib hmos, zoo li lwm cov xov xwm muaj npe nrov zoo yuav qhia. Kuv rov hais dua tias nws tsis zoo, lawv tsuas yog txwv lawv tus kheej rau kev tsim, tsis yog kev tsim khoom. Qhov tseeb, Raspberry Pi Pico nti yog tsim hauv TSMC foundry, nrog 40nm ntawm. Thiab peb yuav tau pom tias qhov no yog ib qho kev coj ntawm SoCs yav tom ntej, lossis yog tias nws tsuas yog qee yam tshwj xeeb thiab lawv yuav txuas ntxiv siv Broadcom ...

Los ntawm txoj kev, thev naus laus zis ntawm sau hnub qub lithographYog lawm, tab sis nws tsis xav tau ntau dua yog muab cov yam ntxwv yooj yim ntawm cov nti no. Rau dab tsi nws tau tsim, nws ntau dua li ntsib.

Raws li rau operating system, qhov tseeb yog tias koj yuav tsis tau nruab Linux lossis lwm tus, ib yam li lwm tus ntawm SBCs. Tsis yog, ntawm no koj tuaj yeem ntxig cov program rau nws khiav. Ntawd yog, nyob rau hauv qhov kev txiav txim zoo nws yog qhov zoo sib xws rau Arduino board.

Koj tuaj yeem sau kos duab kos duab hauv hom lus programming nyiam C lossis MicroPython hauv lub PC thiab thauj lawv los ntawm microUSB hauv lub cim xeeb ntawm koj Raspberry Pi Pico. Yog li, microcontroller yuav tuaj yeem ua rau lawv thiab ua haujlwm ntawm GPIO pins.

Qhov tseeb tiag, tsis txhob xav tias yuav muaj txiaj ntsig zoo. Yog ib txwv phaj vim tias nws tau tsom mus rau qee hom kev thov. Ntxiv rau qhov tsis tuaj yeem nruab ib qho OS, koj tseem yuav khiav mus rau qhov tsis txaus ntseeg ntawm kev txuas wireless vim nws qhov me me.


Cov ntsiab lus ntawm tsab xov xwm ua raws li peb cov ntsiab cai ntawm kev tswj hwm kev ncaj nceesCov. Tshaj tawm ib qho yuam kev nyem no.
