Eben Upton, Raspberry Pi Muvambi, nguva pfupi yadarika yakazivisa iyo nyowani "Raspberry Pi Pico W" ine yakavakirwa-mukati Wi-Fi. Iyo Raspberry Pi Pico W ishanduro yakavandudzwa zvishoma yegore rapfuura $4 Raspberry Pi Pico.
Izvo zvinofanirwa kucherechedzwa kuti sezvizvi hazvigone kushandiswa sekombuta; pachinzvimbo, inoshanda senge microcontroller board yeDIY zvemagetsi mapurojekiti. Kufanana nePi Pico yepakutanga, ine RP2040 microcontroller ine maviri ARM Cortex-M0+ cores uye 264kB yeSRAM.
Kune avo vasati vaziva nezve Raspberry Pi, vanofanirwa kuziva kuti ndizvo an ARM-based single board nanocomputer Saizi yekadhi rechikwereti rakagadzirwa nemapurofesa kubva kuDhipatimendi reComputer Science paYunivhesiti yeCambridge sechikamu cheRaspberry Pi Foundation.
Yakagadzirwa kuti iite democratize komputa, kuwana makomputa uye kugadzira dhijitari. Iyo Raspberry Pi inotsigira kuurayiwa kwezvakasiyana zvakasiyana zveGNU/Linux, kunyanya Debian, uye software inoenderana. Inoshanda zvakare neMicrosoft Windows inoshanda sisitimu: Windows 10 IoT Core6, Windows 10 paARM, Google Android Pi7 uye kunyange vhezheni yeIBM's OS/MVT inoperekedzwa neAPL\3602 system.
"Muna Ndira wegore rapfuura, takaparura $4 Raspberry Pi Pico, yedu yekutanga silicon-yakavakirwa chigadzirwa chakagadzirwa pano paRaspberry Pi. Mwoyo wayo iRP2040 microcontroller, yakavakirwa paTSMC yakaderera-simba 40nm maitiro uye ichibatanidza maviri 133MHz Arm Cortex-M0+ cores, 264KB ye-on-chip SRAM, uye yedu yakasarudzika programmable I/O subsystem, "akadaro. Eben Upton.
Nezve Raspberry Pi Pico W
Iyo Raspberry Pi Foundation yakaburitsa nhengo nhatu nyowani dzemhuri yePico. Iyo Raspberry Pi Pico W ($ 6) inounza 802.11n isina waya network kuPico papuratifomu, ichiramba ichienderana kuzere nemukoma wayo. Pico H ($5) uye Pico WH ($7) vanowedzera misoro yakarongedzerwa uye yedu itsva 3-pini debug yekubatanidza kuPico nePico W zvichiteerana. Pico H uye Pico W zviripo nhasi; Peak WH ichatevera muna Nyamavhuvhu.
Iyo huru yekusimudzira nePico W ndiyo yakasanganiswa 2,4 GHz Wi-Fi module, inova yekuwedzera inobatsira kune chero munhu ari kuedza kuzvivakira ega ega ega ega madhizaini epamba kana mamwe mapurojekiti akadaro. ace.
Kubva payakatangwa, makadhi ePico anoda kusvika mamirioni maviri akatengeswa uye iyo RP2040 yawana nzira yayo muhuwandu hwezvigadzirwa zvechitatu. Iyo RP2040 yakanakira kushambadzira uye maindasitiri kunyorera, uye kushomeka kwepasi rose kwema semiconductors kwakawedzera zvakanyanya kutorwa kwayo.
Iine ndangariro hombe uye inochinjika interface, iyo RP2040 inokodzera Internet yezvinhu (IoT) application. Nekudaro, Pico pachayo ine chiri pachena chisipo cheIoT: nzira yekubatanidza kunetiweki, asi mamiriro aya akatariswa uye timu pa. Raspberry yakashanda neInfineon kuwedzera yavo CYW43439 isina waya chip kuPico W. Iyo redhiyo redhiyo yakavharirwa mune yesimbi kesi, ichidzikisa kuteedzera mutengo kune vatengi vanoda kuibatanidza muzvigadzirwa zvavo.
Chinhu chinonakidza pazviri ndechekuti CYW43439 inotsigira Bluetooth Classic uye Bluetooth Yakaderera-Energy, kunyangwe zvakakodzera kutaura kuti timu yekuvandudza Raspberry haina kugonesa Bluetooth pakuvhurwa paPico W.
Mukuwedzera kune izvozvo zvakare SDK yakaburitswa inosanganisira tsigiro yekubatanidza isina waya, iyo networking stack yakavakirwa kutenderedza lwIP uye inoshandisa Damien George's libcyw43 (anozivikanwa nebasa rake paMicroPython) kutaurirana newireless chip.
Nekumisikidza, libcyw43 inopihwa rezinesi rekushandisa kusiri-kutengesa, asi vashandisi vePico W uye chero munhu ari kuvandudza chigadzirwa chavo akatenderedza RP2040 uye CYW43439 vanowana rezinesi remahara rekushandisa kutengesa.
The users of micropython Zvinonzi vanogona dhawunirodha mufananidzo weUF2 wakagadziridzwa nerutsigiro rwetiweki yePico W.
Kutanga madhairekitori eC uye MicroPython, pamwe nezvinongedzo kune API level zvinyorwa, zve kuva online, anowanikwa mu microcontroller chikamu.
Chekupedzisira, kana iwe uchifarira kuziva zvakawanda nezvazvo, unogona kutarisa ruzivo Mune inotevera chinongedzo.
