ShieldPi Pro ha se feela Raspberry Pi EMI shield HAT, empa hape ke mochini o sebetsang hantle oa phepelo ea matla, konopo ea ON/OFF le GPIO extender/multiplier. Ts'ebetso ea taolo e hole ea IR e ka boela ea sebelisoa ha o sebetsa 'moho le MonitorPi.
ShieldPi Pro e loketse lits'ebetso tsohle tsa RespberryPi ho fokotsa lerata la EMI le lerata la phepelo ea motlakase. Ntlafatso e ka etsoa hang-hang ka ho e kenya feela ka har'a sistimi.
B. Likarolo le Lintlha Tse Totobalitsoeng
- Letlapa la thebe le nang le ntlha e le 'ngoe ea Zero hona joale ho felisa lerata la EMI la Raspberry Pi
- Ultra-tlase ESR bophara ba bandwidth 5V marangrang a phepelo ea phepelo ea matla a koahelang lebelo ho fihla ho GHz ESR: 2m@200KHz, 0.3m/@2Mhz, 1m@20MHz, 4m/@200MHz
- Likhoele tse 40 tse felletseng tsa GPIO extender
- Lipini tse felletseng tse 40 tsa GPIO multiplier (AUX GPIO)
- E na le konopo ea Raspberry Pi GPIO ON/OFF le sehokelo sa konopo ea matla a kantle
- E na le matla a boikhethelo a pontšo ea LED le tlhahiso ea lets'oao la ho tima/ho tima
- E ka kenya tšebetsong ts'ebetso ea taolo e hole ea IR ea Raspberry Pi ha e sebetsa le MonitorPi
- Fokotsa ka bobeli lerata la EMI le lerata la phepelo ea motlakase
- Ntlafatsa ts'ebetso ea Raspberry Pi ho ea boemong bo holimo
- DIY e mosa 'me e plug le ho bapala
C. Ponahalo le Boholo (ka limilimithara)
D. Ho qala
- Etsa bonnete ba hore lisebelisoa tsa hau tsa RaspberryPi le software li hlophisitsoe hantle 'me li sebetsa hantle.
- Kenya ShieldPi Pro J3 ho sehokelo sa GPIO sa RaspberryPi. Ka kopo sebelisa li-standoffs tsa 11mm.
- Kenya li-HAT tse ling boema-kepeng ba GPIO J1 ka holim'a ShieldPi Pro.
- Kenya MonitorPi ho AUX GPIO J2 ea ShieldPi Pro (ho ikhethela).
- Matlafatsa sistimi joalo ka tloaelo.
- Natefeloa ke 'mino.
E. Lihokelo le lisebelisoa tse ling
J3: GPIO sokete
J1 e hloka ho kenngoa ho sehokelo sa Raspberry Pi GPIO.
J1: Sehokelo sa GPIO
J2 ke katoloso ea boema-kepe ba RasberryPi GPIO. DAC kapa li-HAT tse ling li hloka ho kengoa sehokelong sena sa GPIO.
J2: Sehokelo sa AUX GPIO
J2 ke boema-kepe ba RasberryPi GPIO bo kopilitsoeng. MonitorPi kapa HAT e 'ngoe e hlokahalang e ka kenngoa sehokelong sena.
S1: Konopo ea ON/OFF
RaspberryPi e ka buloa kapa ea koaloa ka mokhoa o sireletsehileng ka ho tobetsa konopo ena (e ka hloka tšehetso ea software).
J5: Sehokelo sa konopo sa kantle sa ON/OFF
J5 e sebetsa ka ho lekana le S1. Konopo e ka ntle e ka kopanngoa le sehokelo sena ho etsa ts'ebetso e ts'oanang ea taolo ea ON / OFF. J5 ke sehokelo sa 2pin PH2.0mm.
D1: Boemo ba matla ba LED
D1 e etselitsoe ho bonts'a boemo ba ho tima / ho tima. Ts'ebetso ena e tlameha ho etsoa ke software.
J4: Sehokelo sa tlhahiso ea taolo ea ON/OFF
J4 e entsoe e le lets'oao la taolo bakeng sa phepelo ea motlakase ea DAC kapa phepelo e 'ngoe ea molumo. J4 e lumellana ka mokhoa o utloahalang le boemo ba matla ba LED D1. E lokela ho boloka logic e phahame ha matla a le teng. J4 ke sehokelo sa 2pin PH2.0mm.
F. Molao-motheo oa ts'ebetso
ShieldPi Pro e entsoe ka mahlakoreng a mabeli a holimo a PCB.
Lehlakore le ka holimo, kapa re le bitsa lehlakore la molumo ke lera le hloekileng la thebe. Lera lena ke sekotoana se felletseng sa poleiti ea koporo e theotsoeng ka ntlha e le 'ngoe. Ka lebaka la hore ha ho na leha e le efe ea hona joale e fetang lera lena la thebe, lerata la EMI le tsoang ho Raspberry Pi le tla thibeloa ntle le ho kenya li-HAT tsa molumo ka sebaka se pakeng.
Lehlakore le ka tlase, kapa re le bitsa lehlakore la Pi ke marang-rang a pharalletseng a phepelo ea motlakase ho ntlafatsa karabelo e matla ea phepelo ea matla a Raspberry Pi le ho theola lerata. Marang-rang ana a sefang a sebelisa motsoako oa polymer, le lihlopha tsa NP0 capacitor ho fihlela ts'ebetso ea ESR e tlase haholo ho feta maqhubu a pharalletseng a GHz.
Ka ShiledPi Pro e kentsoeng tsamaisong, lerata la EMI le lerata la phepelo ea motlakase li tla fokotseha. Ka hona, ho ka lebelloa ntlafatso.
Ho etsa ts'ebetso e sireletsehileng ea matla le ho koala ts'ebetso, ShiledPi Pro e kopantsoe le konopo ea matla ea ho tima / ho tima ea Raspberry Pi GPIO le boemo ba matla ba LED. Matla a terateng ea taolo a hoketsoe ho GPIO3 (kapa PIN5, matla a kamehla a Raspberry Pi ho GPIO pin), ha terata e timang e hoketsoe ho GPIO4 (PIN7). Letšoao la matla la LED D1 le hoketsoe ho GPIO17 (PIN11)
Ts'ebetso ea taolo e hole ea RaspberryPi IR e ka sebelisoa hape haeba MonitorPi e kentsoe sehokelong sa AUX GPIO J2. Letšoao le amohelang IR le tla hokeloa ho GPIO25 (PIN22).
Matla a GPIO a sebetsang a lumelloa ka mokhoa oa kamehla. RaspberryPi e ka buloa ha o tobetsa konopo S1 ka mor'a hore e koaloe ka har'a software.
Leha ho le joalo, ts'ebetso ea konopo ea S1 e koaletsoeng ka mokhoa o sireletsehileng e tlameha ho kengoa ho software. Nka example, haeba re sebelisa Volumio, re ka e etsa ka tsela ena:
- Kenya li-buttons tsa GPIO plugin.
- Lokisa litlhophiso tsa plugin ena joalo ka tlase.
Lemoha ka kopo:
- Ka kopo sebelisa mofuta oa morao-rao oa RaspberryPi o nang le bootloader e ntlafalitsoeng ka ho fetesisa ho netefatsa ts'ebetso ena.
- Litlhophiso tsa software ea libapali tse ling li ka fapana. Ka kopo botsa morekisi oa software haeba o hloka thuso.
- LED e tala ho RaspberryPi e tla qala ho bonesa ha o tobetsa konopo ho bulela, 'me e tla lula e tima ka mor'a ho koala ka mokhoa o sireletsehileng.
H. Mokhoa oa ho nolofalletsa boemo ba matla ba LED
Boemo ba matla ba LED D1 bo tlameha ho kenngoa ho software. Nka example, haeba re sebelisa Volumio, re ka e etsa ka tsela ena:
- Kenya GPIO control plugin.
- Lokisa litlhophiso tsa plugin ena joalo ka tlase.
I. Mokhoa oa ho nolofalletsa IR-remote controller mosebetsi
- Kenya MonitorPi ho sehokelo sa AUX GPIO J2
- Haeba u sebelisa software ea Volumio, re hloka ho kenya plugin ea IR Remote Controller.
- Lokisa litlhophiso tsa plugin ena joalo ka tlase.
Ka kopo hlokomela, IR-remote controller e ke ke ea sebetsa haeba pro e fosahetsefile e khethiloe. Bakeng sa taolo e hole ea aluminium ea Apple, re hloka ho khetha A1156 E 'ngoe. Bakeng sa taolo e 'ngoe e hole, re hloka ho khetha profile ka nepo. U ka boela ua leka mekhoa e fapaneng ea profiles ho fihlela remote controller e sebetsa.
