Gbaa mbọ hụ na ahaziri ngwaike sistemụ RaspberryPi gị na ngwanrọ nke ọma ma na-arụ ọrụ nke ọma.
Wụnye ShieldPi Pro J3 n'ime njikọ GPIO nke RaspberryPi. Biko jiri ihe mgbochi 11mm.

Wụnye okpu ndị ọzọ na ọdụ ụgbọ mmiri GPIO J1 n'elu ShieldPi Pro.
Wụnye MonitorPi n'ime AUX GPIO J2 nke ShieldPi Pro (nhọrọ).

Kwado usoro ahụ dị ka ọ dị na mbụ.
Nwee egwu egwu.

E. Njikọ na ihe ndị ọzọ

J3: oghere GPIO
Ekwesịrị itinye J1 n'ime njikọ Raspberry Pi GPIO.

J1: GPIO njikọ
J2 bụ ndọtị nke ọdụ ụgbọ mmiri RasberryPi GPIO. Ekwesịrị itinye DAC ma ọ bụ okpu ndị ọzọ na njikọ GPIO a.

J2: AUX GPIO njikọ
J2 bụ ọdụ ụgbọ mmiri RasberryPi GPIO oyiri. Enwere ike itinye MonitorPi ma ọ bụ okpu ọzọ achọrọ n'ime njikọ a.

S1: bọtịnụ gbanye / gbanyụọ
Enwere ike ịgbanwuo ma ọ bụ mechie RaspberryPi site na ịpị bọtịnụ a (nwere ike ịchọ nkwado ngwanrọ).

J5: Njikọ bọtịnụ Mpụga/ Gbanyụọ
J5 dabara na S1. Enwere ike ijikọ bọtịnụ mpụga na njikọ a iji rụọ otu ọrụ njikwa ON/ Gbanyụọ. J5 bụ 2pin PH2.0mm njikọ.

D1: Ọkwa ike LED
Emebere D1 iji gosi ọkwa ngbanwu/ gbanyụọ. Ngwanrọ kwesịrị ịgbanye ọrụ a.

J4: Njikọ nke mmepụta njikwa ike ON/OFF
A haziri J4 ka ọ bụrụ akara njikwa maka ọkụ DAC ma ọ bụ ike ọdịyo ọzọ. J4 bụ ihe ezi uche dị na ya na ọkwa ike LED D1. O kwesiri iburu n'uche elu mgbe ike na-agbanye. J4 bụ 2pin PH2.0mm njikọ.

F. Ụkpụrụ ọrụ

Emebere ShieldPi Pro na PCB n'akụkụ abụọ.

N'elu akụkụ, ma ọ bụ anyị na-akpọ ya audio n'akụkụ bụ a dị ọcha ọta oyi akwa. Igwe oyi akwa a bụ efere ọla kọpa nwere ntụ ntụ zuru oke. N'ihi na ọ nweghị ihe ọ bụla ugbu a na-aga site na oyi akwa ọta a, a ga-egbochi mkpọtụ EMI sitere na Raspberry Pi na-ewebataghị n'ime okpu ọdịyo site na oghere dị n'etiti.

N'akụkụ ala, ma ọ bụ anyị na-akpọ ya akụkụ Pi bụ obosara bandwidth ike ọkọnọ netwọk nzacha iji melite Raspberry Pi ike ọkọnọ nzaghachi ike na-ebelata mkpọtụ. Netwọk nzacha a na-eji nchikota nke polymer, na NP0 capacitor otu iji nweta arụmọrụ ESR dị ala karịa ogologo oge gbatịrị GHz.

Site na ShiledPi Pro arụnyere na sistemụ, ma mkpọtụ EMI na mkpọtụ ọkọnọ ike ga-ebelata. Ya mere, enwere ike ịtụ anya nkwalite.

Iji rụọ ọrụ nchekwa ma gbanyụọ ọrụ, ShiledPi Pro jikọtara ya na bọtịnụ mgbana/ gbanyụọ Raspberry Pi GPIO yana LED ọkwa ike. Ejikọrọ ike dị na waya njikwa na GPIO3 (ma ọ bụ PIN5, ike ndabara Raspberry Pi na pin GPIO), ebe njikwa ọkụ na-ejikọta na GPIO4 (PIN7). Ihe ngosi ike LED D1 jikọọ na GPIO17 (PIN11)

Enwere ike mejuputa ọrụ njikwa IR-Remote RaspberryPi ma ọ bụrụ na etinyere MonitorPi n'ime njikọ AUX GPIO J2. A ga-ejikọta akara nnata IR na GPIO25 (PIN22).

G. Otu esi eme ka bọtịnụ mgbanyụ/ gbanyụọ GPIO

Agbanyere ike GPIO dị na ndabara. Enwere ike ịgbanwuo RaspberryPi mgbe pịa bọtịnụ S1 ka emechiri ya na ngwanrọ.

Otú ọ dị, a ghaghị ịgbanye ọrụ bọtịnụ S1 dị mma na ngwanrọ. Were example, ọ bụrụ na anyị na-eji Volumio, anyị nwere ike ime ya n'ụzọ dị otú a:

Wụnye ngwa mgbakwunye bọtịnụ GPIO.
Hazie ntọala ngwa mgbakwunye a dị ka n'okpuru.

Biko rụba ama:

Biko jiri ụdị RaspberryPi kachasị ọhụrụ nwere bootloader emelitere iji hụ na ọrụ a dị.

Ntọala nke ngwa ngwa ndị ọzọ nwere ike ịdị iche. Biko jụọ onye na-eweta ngwanrọ ma ọ bụrụ na ịchọrọ enyemaka.
Igwe ọkụ na-acha akwụkwọ ndụ na RaspberryPi ga-amalite ịgba ọkụ mgbe pịa bọtịnụ ka ịgbanwuo, ọ ga-anọkwa n'anya mgbe emechara nchekwa.

H. Otu esi eme ka ọnọdụ ọkụ ọkụ ọkụ

Ekwesịrị ịgbanye ọkwa ike LED D1 na ngwanrọ. Were example, ọ bụrụ na anyị na-eji Volumio, anyị nwere ike ime ya n'ụzọ dị otú a:

Wụnye ngwa mgbakwunye njikwa GPIO.
Hazie ntọala ngwa mgbakwunye a dị ka n'okpuru.

I. Otu esi eme ka ọrụ njikwa IR-remote

Wụnye MonitorPi n'ime njikọ AUX GPIO J2
Ọ bụrụ na-eji ngwanrọ Volumio, anyị kwesịrị ịwụnye ngwa mgbakwunye IR Remote Controller.

Hazie ntọala ngwa mgbakwunye a dị ka n'okpuru.

Biko mara, njikwa IR-remote agaghị arụ ọrụ ma ọ bụrụ na pro na-ezighi ezifile ahọpụtara. Maka Apple aluminum remote controller, anyị kwesịrị ịhọrọ A1156 Nhọrọ. Maka njikwa ime anya ndị ọzọ, anyị kwesịrị ịhọrọ profile ya mere. Ị nwekwara ike ịnwale pro dị iche ichefiles ruo mgbe remote controller na-arụ ọrụ.
