Iyo Raspberry Pi Project yakafumura iyo nyowani Raspberry Pi Pico W bhodhi, ichienderera mberi nekuvandudzwa kweiyo miniature Pico bhodhi, yakashongedzerwa ine muridzi weRP2040 microcontroller. Iyo itsva edition inosiyaniswa nekubatanidzwa kweWi-Fi rutsigiro (2.4GHz 802.11n), inoshandiswa pahwaro hweInfineon CYW43439 chip. Iyo CYW43439 chip inotsigirawo Bluetooth Classic uye Bluetooth Low-Energy, asi haisati yabatanidzwa mubhodhi. Mutengo webhodhi idzva imadhora matanhatu, inova madhora maviri kupfuura yekutanga sarudzo. Pakati penzvimbo dzekushandisa, pamusoro pekugovana nemakomputa eRaspberry Pi, kugadzira masisitimu akadzamirwa uye masisitimu ekudzora ezvishandiso zvakasiyana, iyo Wi-Fi sarudzo inomisikidzwa sepuratifomu yekugadzira Internet yezvinhu (Internet yezvinhu) zvishandiso zvinopindirana pamusoro peimwe. network.
Iyo RP2040 chip inosanganisira mbiri-musimboti ARM Cortex-M0+ (133MHz) processor ine 264 KB ye-on-board RAM (SRAM), DMA controller, tembiricha sensor, timer, uye USB 1.1 controller. Bhodhi rine 2 MB yeFlash memory, asi chip chinotsigira kuwedzera kusvika ku16 MB. Kune I / O, GPIO ports inopihwa (mapini makumi matatu, ayo mana akagoverwa kupinza analog), UART, I30C, SPI, USB (mutengi uye anotambira nerutsigiro rwekubhowa kubva kumadhiraivha muUF4 fomati) uye nyanzvi 2 pini PIO ( Programmable I / O mamiriro emuchina) kubatanidza ako eparipherals. Simba rinogona kupihwa mumhando kubva ku2 kusvika ku8 volts, iyo inobvumidza iwe kushandisa akasiyana emagetsi masosi, kusanganisira maviri kana matatu akajairika mabhatiri eAA kana standard lithium-ion mabhatiri.
Zvishandiso zvinogona kugadzirwa uchishandisa C, C++, kana MicroPython. Iyo MicroPython port yeRaspberry Pi Pico yakagadzirirwa pamwe chete nemunyori wepurojekiti uye inotsigira ese maficha eiyo chip, kusanganisira yayo pachayo interface yekubatanidza PIO yekuwedzera. Nekusimudzira iyo RP2040 chip uchishandisa MicroPython, iyo Thonny yakasanganiswa programming nharaunda yakagadziridzwa. Iko kugona kweiyo chip kwakaringana kumhanyisa zvikumbiro zvekugadzirisa matambudziko ekudzidza muchina, kuitira kusimudzira iyo chiteshi cheTensorFlow Lite chimiro chakagadzirirwa. Kuti uwane network, zvinokurudzirwa kushandisa lwIP network stack, iyo inosanganisirwa mushanduro itsva yePico SDK yekugadzira maapplication mumutauro weC, pamwe neiyo nyowani firmware ine MicroPython.
