Serial Peripheral Interface ko SPI ya ci gaskiya na aikin wataƙe daga system na embedded don kula processors da device mai baya mai tsaye, kamara, da displays. Kamara SPI suna iya yi aikin wannan standard don rubutu data na image.

Daga cikin dunia na system na embedded da device na elektronik, kamara SPI (Serial Peripheral Interface) suka yi addin rubutun da yanzu tare da yin aiki sauran .

Gudanarwa Na SPI Communication

Don hanyar bukatar kuma kaiƙaɗa details naSPI cams, marasuka samfuna masana'annan na SPI communication. SPI ya ci gaskiya na aikin serial communication don kula devices suna iya kula a matsayin distance. Taimakon, ya ne babban device (masan, microcontroller) da biyu amma abubuwa slave devices (masan, sensors ko peripherals).

Kununkwana SPI ya gaskiya ne suna da biyu amfani da shirin tsarin:

• SCK (Serial Clock): Tsari na yanzu ya kuma yi a cikin mai gudanarwa, ya kamata ne daga mai gudanarwa da aka sami masu hanyar clock don bayyana.
• MOSI (Master Out Slave In): Mai gudanarwa ya buƙatar data don mai ƙasa a cikin tsari na yanzu.
• MISO (Master In Slave Out): Mai ƙasa ya buƙatar data don mai gudanarwa a cikin tsari na yanzu.
• SS (Slave Select): Tsari na yanzu ya kamata ne don samun mai ƙasa mai gudanarwa an yi amfani da.

Fahimtsa Kamera SPI

A nan da aka fahimta da kununkwana SPI an yi amfani da, ake son bincika wannan labarar da kamera SPI. Kamera SPI ya gabatar da sensor tsohuwar, lens, da serial-cluster interface (SPI) daga cikin wani rubutu compact. Kamar so, kamar SPI ya kamata ne don sake tambaya wani hannun tsohuwar ko sake record video, da aka buƙatar data don processor ko microcontroller don amfani da.

Kamara SPI ya yi aikin daidai ke daga cewa ya kuma yana iya gudanarwa don hanyar da aka sami:

• Intigirashin Da Fadawa: Kamarar SPI ya ci gaba rubutuwa na komunikashi a ce wonan ne shi ne a cikin hannun wirin - sashe (SCLK), labarar mai tsarin labari (MOSI), labarar mai alama labari (MISO), da labarar binciken (SS). An yi amfani da wannan, ya yi amfani da wirin daidai da kawai rubutu. Don gaskiya, shi ya kamata an yi taimakon zuwa sistemar wanda ya kasance.
• Sabon Alama: Kamarar SPI ya saboda wannan, ya saboda wannan a cikin hannun wirin da aka sami daidai compared to USB or GigE Vision cameras. Wannan ya saukar masu rabin gida. Don gaskiya, ya kamata an yi taimakon zuwa hakuri na jihar, IoT (Internet of Things) hakuri, robotics, da sistemar wanda ya saboda.
• Tare da Tsallakin Littafin: Kamarar SPI ya fiye aiki da tsallaki littafi. Wannan ya kamata an yi taimakon zuwa hakuri na battari ko aikin wanda ya kawo fadi da tsallaki.
• Kayan Fasalin Ruwa: Kamera SPI yana soya shafi ko gaskiya a cikin fasalin ruwa, kuma yanzu yana iya aikatawa daga cikin wannan fasalin da ke nuna dattaka a cikin wani hanyar. Daga cikin wannan, ya kamata amfani da systema ne suna kasance, rubutuwa masu riga, samun abubuwan object.
• Taimakon Da Kayan Fasalin: Don kamera SPI na manyan, paramita mutum mai tsaye ake sosai maya ne resolution, frame rate, expose, da gain options. Wannan taimako ne an yi amfani da aka gabatar da kwalite ta fasalin da aka sami a cikin wasu takardunna.

Babban da wannan, kamera SPI suna suna hanyar teknikai:

• An ci gudanarwa don labararwa, da data an yi amfani da aka samun nan a cikin rising/falling edges of a clock signal an yi amfani da master processor.
• SPI an sanya wasu slaves don SS lines, an yi amfani da aka samun nan a cikin wasu kamera/peripherals idan yake mutane master.
• Speeds na transfer suna zage da hundreds of Kbps to tens of Mbps depending on clock speed - fast enough for many vision applications.
• Kamara SPI ya dafa karamin chip na biyu mai tsaye da ke USB/Ethernet, a cikin yadda ya yi amfani da tsohon gaba, na cost lowa, an yi shi a kan latsa da wata kasance.

Taimakon da Software Support

Support software mai saiti ne daya da ke daga wannan taimakoSPI kamara.

Binciken SPI kamarar da libraries ko APIs (Application Programming Interfaces) mai aiki da commands da functions a ce cin lokacin operation kamara, capture image, da adjustment settings. Libraries haka ne da aka yi amfani da microcontroller systems na system development tools, ya karatun taimakon da software integration procedure easy.

Kadai, ba za'a iya samun baƙoyar image processing functions a cikin Camera Module , ya kawo masu rikicen system a cikin CPU ko host microcontroller. A matsayin, kamarar haka suna iya samun functions mai amfani da image compression, color adjustment, ko anaɓɓuwa image analysis algorithms.

Kamara SPI ya biyu aiki da wani aiki na dadi da kuma jihar mutane a cikin wannan suna daidai a cikin rubutun shi. A matsayin haka, suka ne da tsohon labarantawa da idan yanzu da aka fiye aiki na tsarin rayuwa, suka ne daidai da aka samfira a cikin aikin gudanarwa. Daga wannan kasancewa ta faruwar rubutun surveillance ta kula aikin vision masanaiki ko projekta IoT, kamara SPI ya ne wani aiki na kewaye da kuma mafi gyara da aka samfira wannan masalaci. Idan yana aiki na fitacce da support softwareSPI camcorders, sabon mahauta na samun fayil da analizewa a cikin system vision kaɗai ne gabatar da kyau.

Sinoseen ya zo da abubuwan bayanin daidai a cikin design da production na kamara, da aka zama aiki na professional da support, a matsayin haka, a samfira need za'a amfani ba, ya ci gaba solution na vision embedded don ka. Idan ka nufi, shigar da kasa daidai Kunna Mana .
