Raspberry Pi Peak iri idzva microcontroller bhodhi rakagadzirwa neRaspberry Pi Foundation. Chigadzirwa chitsva icho ajoina zviripo uye ndeipi yakafanana Arduino kupfuura SBC. Pamusoro pezvo, ine chimwezve chakashamisa chakashamisa munhu wese, uye chinoenda kupfuura saizi yayo diki, kugona simba kwesimba, kana mutengo wayo we $ 4 chete.
Uye ndeyekuti iyo Raspberry Pi Foundation yakashandura, zvirinani kwechinguva, kuita isina shangu, ichigadzira yayo yega chip. Zvayo ndezve RP2040 SoC. Ndokunge, kwenguva ino, ivo havana kushandisa Broadcom machipisi semamwe mabhodhi, asi vakazvigadzira ivo pachavo. Tichaona kana mune ramangwana vanotevedzera maitiro akafanana mune mamwe mahwendefa kana kana chave chiri chinhu chakatarwa ...
RP2040 SoC
El RP2040 ndiyo yekutanga chip yakagadzirirwa neRaspberry Pi Foundation. Dhizaini yakagadzirirwa pamba kusimudzira ino diki-diki uye yakasviba-yakatetepa bhodhi uye yakagadzirirwa mapurojekiti uko saizi nekushandisa zvakakosha, senge mamwe akasimbwa kana akaisirwa mukati marobhoti, indasitiri, mota, zvinoshandiswa pakurapa, zviteshi zvemamiriro ekunze, nezvimwe.
Kunyangwe zvinotaurwa nevamwe vezvenhau (kunyangwe zvimwe zvakakosha uye zvine mbiri), hachisi chip chakagadzirwa navo, chakangogadzirwa naivo. SoC yakave yakagadzirirwa neyedu timu yakanangana ne ASIC uye izvo zvakakonzera iyi IC.
Ndokunge, ivo havana kushandurwa kuita IDM, asi ingori ngano dzakatumira dhizaini yavo kuti igadziriswe kune yekutanga TSMC. Mune mafekitori aya 40nm maitiro ave achishandiswa pakugadzira kwavo. Uye hongu, iyo node inogona kuratidzika kunge yechinyakare, asi iyo lithography tekinoroji inopfuura yakaringana chirongwa ichi uye inoita basa rayo chaizvo.
Kudzokera kune dhizaini yeiyo rp2040 SoC iyo inopa simba iyi Raspberry Pi Pico, iri chip umo mairi macres asina kugadzirwa kubva pakutanga, asi asi ivo vakasarudza kushandisa Arm's IP cores. Kunyanya, yakashandisa maviri ARM Cortex M0 + kushanda pa133Mhz. Uye zvakare, yakave yakagadzirirwawo 264 KB ye RAM, uye 2MB ye flash.
Zvese zvisina kunangana kumhanyisa sisitimu inoshanda seLinux (kana vamwe), sezvazvinoitika mune mamwe mabhodhi eSBC, asi Raspberry Pi Pico inogona kungoita sketches kana zvirongwa zvakanyorwa mumitauro senge C / C ++ kana MycroPython. Paunongonyora paPC yako, dzinogona kupfuudzwa kubhodhi kuburikidza neiyo microUSB kuitira kuti iyo MCU unit, kana microcontroller, ivaitise.
Chekupedzisira, ini handidi kuisa parutivi zita remazita rinoshandiswa, uye nderekuti zita RP2040 rine chikonzero charo:
- RP: inomirira Raspberry Pi
- 2: nhamba yemakorari.
- 0: yakakosha mhando (M0 +).
- 4: log2 (RAM / 16kB).
- 0: log2 (isina kugadzikana kana kupenya / 16kB), kana iri 0 iri nekuti iri mubhodhi.
Izvi zvingaite kunge zvakapusa, kunyanya tichifunga kuti parizvino kune imwechete chete SoC yakagadzirirwa navo. Asi zvinogona kuratidza kuti Raspberry Pi Foundation inogona Dhizaina mamwe maSoC mune ramangwana...
Mamwe mashoko - Nhoroondo ye RP2040
Nezve iyo Raspberry Pi Pico bhodhi
Ndiro nyowani Raspberry Pi Peak inochengetedza kushamisika kunofadza, kunyangwe iri diki saizi. Uye chete pamutengo wemadhora mana, izvo zvinoita kuti ive imwe yemabhodhi ekudzivirira macrocontroller pamusika.
Buda-kunze
Kana ari hwokugadzira maitiro uye kutaurwa, heino zvese zvese zveplate:
- SoC: RP2040 yakagadzirirwa muUK neASIC dhizaini rinoshanda rinoshanda reRaspberry Pi Foundation.
- DualCore ARM Cortex-M0 + ine simba rewachi frequency kusvika ku133Mhz.
- 264 kB ye SRAM ndangariro
- 2MB ye pa-bhodhi flash memory.
- Iine yakaderera kwazvo yekushandisa uye isina kurara uye yekurara nzira.
- Kubatana: microUSB ine rutsigiro rweUSB 1.1 Host
- Kuronga: Dhonza uye udonhedze uchishandisa mitauro senge C / C ++ uye MicroPython.
- GPIO: 26-pini yakawanda
- Mamwe mapini: 2x SPI, 2x I2C, 2x UART, 3x 12-bit ADC, 16x chiteshi PWM.
- Zvokudya: 3.3 V
- zvimwe: tembiricha yekushisa, maraibhurari ekukurumidza akayangarara muROM, uye 8x PIO (Inogadziriswa I / O) kuti ikwanise kuchinjisa bhodhi kutsigira zvigadzirwa, nezvimwe. Semuenzaniso, nePIO inogona kugadzirirwa kutevedzera VGA, kurira, SD kadhi kuverenga, nezvimwe.
- Size: 51x21mm
- Mutengo: 4 $ (buy)
Ungatanga sei kuronga
Iyo nyowani Raspberry Pi Pico yakarongedzwa uchishandisa iyo C / C ++ SDK kana yepamutemo MicroPython chiteshi, zvinoenderana nekuti unosarudza kushandisa mumwe mutauro kana mumwe kune ako mapurojekiti. Uye zvakare, chirongwa ichi chinotakurika nyore:
- Zvakare nekubatisisa pasi bhatani reBOOTSEL pabhodhi
- Kubatanidza iyo microUSB tambo kuPc (Linux, Windows, kana macOS, uye iwe unogona kunyange kuronga kubva kuRaspberry Pi 4)
- Ipapo bhatani reBOOTSEL rinoburitswa uye iyo PC inokwidza iyo nyowani unit inonzi RPI-RP2 sekunge yaive pendrive.
- Iye zvino, iwe unongofanirwa kudhonza iyo UF2 kodhi faira kune yeyuniti yeyiti uye inozotakura.
- Iyo Raspberry Pi Pico ichaitazve uye kutanga kumhanyisa chirongwa.
Uye zvakare, iwe zvakare une faira INDEX.HTM mukati meyuniti uye izvo zvinokuratidza iwo epamutemo zvinyorwa pane iyo Raspberry Pi webhusaiti. Imwe INFO_U2F.TXT faira rine ruzivo nezve bhodhi, senge bootloader vhezheni.
