Rasberi Pi Pico

Rasberi Pi Pico sabon kwamiti ne mai sarrafa microbiorol wanda Raspberry Pi Foundation ya tsara. Wani sabon samfurin cewa shiga data kasance kuma wanne yafi kama Arduino fiye da SBC. Bugu da kari, yana da wani babban abin mamakin da ya ba kowa mamaki, kuma ya wuce karami, girman ingancin makamashi, ko farashinsa dala 4 kawai.

Kuma shine cewa Rasberi Pi Foundation ya canza, aƙalla na ɗan lokaci, izuwa wani baƙon abu, da kera ginshiƙinsa. Game da shi Saukewa: RP2040. Wato, a wannan lokacin, basu yi amfani da kwakwalwan Broadcom kamar yadda yake a cikin sauran allon ba, amma sun tsara shi da kansu.

Saukewa: RP2040

Rasberi Pi Pico RP2040

El RP2040 shine guntu na farko da Raspberry Pi Foundation ya tsara. Wani ƙira da aka kirkira a gida don haɓaka wannan ƙaramin ƙarami da siririn sihiri kuma an tsara shi don ayyukan inda girman da amfani suke da mahimmanci, kamar wasu saka ko aikace-aikacen da aka saka a cikin mutum-mutumi, masana'antu, kera motoci, aikace-aikacen likita, tashoshin yanayi, da dai sauransu.

Duk da abin da wasu kafofin watsa labarai ke faɗi (har ma da waɗansu mahimman bayanai masu martaba), ba guntu ba ce suka ƙera da su, kawai sun tsara ta. SoC wanda aka tsara ta ƙungiyarmu ta musamman ASICs kuma hakan ya haifar da wannan IC.

Wato, ba a canza su zuwa IDM ba, amma kawai baƙon abu ne wanda ya aiko da ƙirar su don ƙera su zuwa tushe TSMC. A cikin waɗannan masana'antar an yi amfani da tsari na 40nm don ƙera su. Kuma haka ne, kumburi ne wanda zai iya zama kamar na da, amma wannan fasahar lithography ta fi isa ga wannan aikin kuma tana yin aikinta sosai.

Komawa zuwa ƙirar rp2040 SoC wanda ke ba da ikon wannan Rasberi Pi Pico, yana da guntu wanda ba a tsara abubuwan da ke ciki daga ɓoye ba, amma sun zaɓi yin amfani da Arm's IP cores. Musamman, ya yi amfani ARM Cortex M0 + biyu yana aiki a 133Mhz. Bugu da kari, an kuma samar mata da RAM 264 KB da kuma flash ta 2MB.

Duk basu dace ba don gudanar da tsarin aiki kamar Linux (ko wasu), kamar yadda yake faruwa a wasu allon SBC, amma Raspberry Pi Pico zai iya gudanar da zane ko shirye-shiryen da aka rubuta cikin yare kamar C / C ++ ko MycroPython. Da zarar ka rubuta su a kwamfutarka, za a iya wuce su zuwa hukumar ta cikin microUSB don sashin MCU, ko microcontroller, ya aiwatar da su.

A ƙarshe, Ba zan so in ajiye shi ba nomenclature anyi amfani dashi, kuma shine sunan RP2040 yana da dalilinta:

  • RP: yana nufin Rasberi Pi
  • 2: lambar tsakiya.
  • 0: nau'in mahimmanci (M0 +).
  • 4: log2 (RAM / 16kB).
  • 0: log2 (wanda ba mai canzawa ba ko walƙiya / 16kB), idan 0 ne to saboda yana kan allo.

Wannan na iya zama wawa, musamman ganin cewa a yanzu akwai SoC guda ɗaya da suka tsara. Amma yana iya nuna cewa Rasberi Pi Foundation zai iya tsara ƙarin SoCs a nan gaba...
