Lub Cuaj Hli 2020: Qhov Raspberry Pi thib ob nyob hauv tsev rov ua dua lub hom phiaj PC lub zog xa khoom, tau tsim. Qhov no siv lub kiv cua nyob saum toj - thiab kev teeb tsa cov khoom siv sab hauv rooj plaub PC -PSU yog li ntawd txawv. Kev hloov kho (rau 64x48 pixels), Adafruit SSD1306 tus tsav tsheb lossis Luma Oled rau Python yuav siv los tso cov nkauj lossis cov vis dis aus cov ntaub ntawv ntawm lub me me OLED zaub tso rau pem hauv ntej ntawm rooj plaub. Xav paub ntau ntxiv ntawm no Github.

Lub i2s lub kaus mom suab yog Wolfson WM8960 raws li tau tham hauv ob ntawm kuv Github chaw cia khoom. SSD1306 zaub siv i2c rau kev sib txuas lus thiab yog li ntawd plaub-xaim hlua kab txuas tau txaus txuas nws mus rau Raspberry Pi GPIO txuas (Pins SCL, SDA, 3V3 thiab GND).

Hloov kho tus nab npawb tsav rau SSD1306 hauv nws 64x48 pixel version tau siv tom qab hloov kho Adafruit lub tsev qiv ntawv raws li cov lus pom los ntawm Mike Causer thiab Luma Oled tus tsav tsheb cov lus.

Todo: Cov kab thib ob txuas ntxiv ntawm cov zaub yuav raug siv los qhia Raspberry Pi 5 qhov hluav taws xob muab hluav taws xob siv ib qho ATtiny85 li ADC - sib txuas lus ntawm i2c nrog Raspberry Pi, lossis MCP3002 dual channel 10 -ntsis SPI ADC. Raspberry Pi CPU kub thiab cov ntaub ntawv kiv cua RPM yuav pom tas mus li ntawm kab thib peb ntawm cov zaub. Ob txoj kab no yuav nyob rau 1 thib ob ntawm 5 txhawm rau tiv thaiv OLED hlawv-hauv.

Yav dhau los 2018 thiab 2019: Kuv tau nkees nkees ntawm kev txuas txhua qhov khoom siv rau kuv Raspberry Pi 3 lossis 4 txhua lub sijhawm kuv xav siv nws. Kuv txiav txim siab kuv xav tau Raspberry Pi lub khoos phis tawj txuas nrog lub zog txuas, hard disk lossis SSD rau lub hauv paus cov ntaub ntawv kaw lus thiab cov ntaub ntawv, kiv cua loj uas tuaj yeem tig qeeb thiab ntsiag to, thiab saib thiab hais lus.

Ib qho ntxiv nws tsis yog lub tswv yim zoo los khiav Pi rau lub sijhawm txuas ntxiv los ntawm SD Card - cov no muaj qhov txwv tsis pub sau (txog 10, 000 zaug?) Thiab yog li kuv thiaj txiav txim siab tshawb xyuas ob txoj hauv kev rau khau raj Pi.

Cov duab qhia ua tiav Pi cov ntaub ntawv txuas nrog lub ntsuas me me, hais lus tso suab, thiab wireless combo-keyboard trackpad, thiab Hayley Westenra hu nkauj Scarborough Fair siv Rasbian thiab omxplayer cov vis dis aus nrawm.

Tsis ntev los no kuv tau txais Raspberry Pi 4 4GB thiab hloov Raspberry Pi 3 nrog nws hauv tib lub thawv. Yog xav paub ntxiv thov saib Ntu 6.

Kauj Ruam 2: Kev Tsim Kho thiab Kev Sib Txuas

Ib lub khoos phis tawj qub PSU zoo li yog qhov yooj yim rau tsev Pi, nws lub zog siv, thiab tshem tawm sab nraud USB hard disk. Tsis muaj chaw txaus hauv PSU rooj plaub txhawm rau txhawm rau sab nraud hdd nrog nws rooj plaub - Kuv yog li ntawd qhib nws thiab tsuas yog khaws lub rooj sib tham me me txuas rau hdd. Kuv kuj tau ntxiv lub zog hloov pauv ntxiv rau USB qhov nyob rau sab xub ntiag thiab sab nraub qaum, thiab nws muaj qhov chaw rau lub kiv cua loj kom txhua yam txias, thiab kuv tau npaj rau lub kaus mom DAC kom haum kuv yuav tsum tau txais ib qho. Kuv siv 12v 3A AC-DC fais fab mov ua lub hauv paus PSU, thiab ntxiv ob qhov me me kho tau 5v thiab 7v rau kiv cua, DC-DC PSU's.

Daim duab 1 qhia tag nrho cov khoom siv thaum sib sau ua ke hauv PSU rooj plaub. Kuv tau ua plaub kab USB luv los txuas plaub lub Raspberry Pi USB chaw nres nkoj mus rau lub hard disk, thiab pem hauv ntej thiab sab nraum qab vaj huam sib luag usb txuas.

Cov duab 2 thiab 4 qhia qhov ua tiav Pi cov ntaub ntawv txuas nrog lub ntsuas me me, hais lus tso suab, thiab wireless combo keyboard track pad.

Cov duab 5 txog 10 qhia txog cov ntaub ntawv ua tiav los ntawm ntau lub kaum ntse ntse.

Yog tias koj saib Daim Duab 10 ua tib zoo koj tuaj yeem pom tias kuv tau txuas ob lub xov hlau (xim av thiab dawb) ncaj qha rau raspberry Pi GPIO pins. Hauv qhov no Pi 3 tau siv ncaj qha los ntawm nws GPIO pins 2 lossis 4 yog +5v, tus pin 6 (thiab lwm tus) rau hauv av - tab sis nco ntsoov tias koj yuav tsum tau tshuaj xyuas peb zaug tias koj tab tom muab tsis pub ntau tshaj li 5.2 volt rau cov pins raws li los ntawm kev ua qhov no koj tab tom hla kev tiv thaiv poly-fuse. Kuv siv Pins 2 rau +5v thiab tus pin nyob ib sab ntawm nws rau hauv av. Raws li kuv tab tom muab Pi los ntawm ob txoj cai tswj hwm cov khoom siv - thawj 12v thiab tom qab ntawd 5.1v, Kuv txaus siab nrog cov khoom siv ncaj qha txuas.

Kuv tau txhawj xeeb tias rooj plaub hlau yuav thaiv Raspberry Pi 3 lub peev xwm los txuas rau kuv li Wi -nkaus router - thaum kawg kuv ua ob qhov 2 cm qhov nyob rau ntawm lub vaj huam sib luag sab tom ntej ntawm Pi board nrog qhov tshwm sim uas muaj tus lej tuav ntawm qhov ntsuas Wi-nkaus ntawm Raspbian nyob zoo ib yam txawm hais tias rooj plaub raug kaw lossis qhib.

Cov Lus Qhia Txog Kev Sib Txuas:

Txuas lub zog AC mus rau 12v 3A AC-DC Module los ntawm Lub Hwj Chim Hloov. Txuas 12v cov zis ntawm cov qauv no mus rau DC-DC 5v 3A module uas yuav ua rau lub zog Raspberry Pi (yog kho tau teeb tsa thawj zaug txog 5.1 volt-ntsuas nws) thiab rau qhov me me DC-DC kho qhov kho qhov muag uas yuav ua rau lub zog ntxuam. Txuas 5v cov zis ntawm 5v DC-DC module rau Rapsberry Pi GPIO Pins 4 (+5v) thiab Pin 6 (Hauv av). Txuas lub ouput ntawm qhov me me DC-DC module rau 12v kiv cua thiab kho nws cov zis kom lub kiv cua tig ntsiag to. Txuas hauv av ntawm 5v 3A DC-DC module rau PC PSU rooj plaub. Txuas hauv av thiab 5v ntawm 5v DC-DC module mus rau 3 tus lej voltmeter zaub ntawm lub vaj huam sib luag pem hauv ntej.

Txuas ob ntawm Raspberry PI USB chaw nres nkoj mus rau sab nraub qaum USB siv ob tus txiv neej USB ntsaws, 4 tus xov tooj txuas thiab ob lub USB Poj niam ntsaws rau sab nraub qaum. Txuas ib qho ntawm Raspberry PI USB chaw nres nkoj mus rau pem hauv ntej USB ntsaws siv tus txiv neej USB ntsaws, 4 tus xov tooj txuas thiab ib qho USB Poj niam lub qhov (socket) tau teeb rau ntawm xub ntiag.

Txuas lub hard disk mus rau ib qho ntawm Raspberry PI USB chaw nres nkoj ntawm tus txiv neej USB ntxiv rau thiab lwm lub mini USB txiv neej ntsaws.

Kauj Ruam 3: Teeb Hard Boot Boot Setup

Nws tsis yog lub tswv yim zoo los khiav Pi rau lub sijhawm txuas ntxiv los ntawm SD Card - cov no muaj cov ntawv sau txwv (txog 10, 000 zaug?) Thiab kuv thiaj li txiav txim siab tshawb nrhiav ob txoj hauv kev rau khau raj Pi:

(1) Muab lub khau raj thiab hauv paus ntxiv rau cov neeg siv muab faib rau ntawm hard-disk

(2) Tawm me me 50 MB Dos khau raj muab faib rau ntawm daim npav SD (nws nyeem-tsuas yog thaum khau raj), thiab txav lub hauv paus cov ntaub ntawv kaw lus thiab cov neeg siv cov ntaub ntawv mus rau lub hard disk.

Nws yog qhov yooj yim heev kom tau Pi rau khau raj los ntawm lub hard disk - Kuv tau theej tshiab Raspian Stretch rau SD daim npav siv Win32DiskImager cov khoom siv. Kuv kuj siv nws zaum thib ob los theej cov duab tib yam rau 1 GB Toshiba 2.5 phau ntawv tsav tsheb, tom qab ntawd kuv teeb Pi lub khau raj fuse raws li tau piav qhia hauv kab ntawv txuas ntawm qhov kawg (koj ntxiv kab program_usb_boot_mode = 1 rau /boot / config.txt, thiab rov pib dua Pi), tshem daim npav SD, thiab Pi tom qab ntawd pib los ntawm lub hard disk thiab txuas ntxiv los hloov nws cov ntawv faib.

Txhawm rau pab kom USB boot hom ua cov hauv qab no:

ncha program_usb_boot_mode = 1 | sudo tee -a /boot/config.txt

Qhov no ntxiv program_usb_boot_mode = 1 mus rau qhov kawg ntawm /boot/config.txt. Reboot Raspberry Pi. Txheeb xyuas tias OTP tau ua haujlwm nrog:

vcgencmd otp_dump | pib 17:.

Xyuas kom cov zis 17: 0x3020000a tau qhia uas txhais tau tias OTP fuse tau ua tiav txoj haujlwm.

Koj tseem tuaj yeem ntxiv kab program_usb_boot_mode kab los ntawm config.txt tus nano editor siv cov lus txib sudo nano /boot/config.txt.

Txawm li cas los xij muaj teeb meem thaum hloov pauv ua li no, vim tias kuv yuav tsum tau muab lub zog ntxiv rau lub hard disk ntawm lub txuas USB thib ob, lub disk khaws cia ntawm kev ua haujlwm tom qab Pi tau tua thiab kuv thiaj li yuav tsum tau hloov lub zog disk los ntawm kev tawm ntawm lub zog hloov pauv ntawm lub vaj huam sib luag pem hauv ntej. Qhov kuv xav tau yog rau Pi rau "nres" lub hard disk thaum hloov pauv. Yog tias kuv tshem tawm qhov txuas hluav taws xob txuas txuas Pi tsis kam khau raj los ntawm hard disk.

Muaj ob daim ntawv teeb tsa cov ntaub ntawv (teeb tsa. Txt thiab cmdline.txt), hauv cov ntawv tais ceev tseg ntawm Dos khau raj muab faib uas ib tus tuaj yeem hloov kho hauv kev sim muab lub zog ntxiv rau lub hard disk thaum khau raj, lossis tos ntev dua rau disk kom pib tig.

Ntxiv: rootdelay = 5, thiab program_usb_timeout = 1 thiab max_usb_current = 1 rau cov npe ntev hauv /boot/config.txt file. (Qhov kev xaiv rootdelay yuav raug txiav tawm).

Ntxiv: boot_delay = 32 thiab ntxiv rootdelay = 5 rau kab hauv /boot/cmdline.txt yuav tsum ua rau lub ntsiav tos rau lub hauv paus ntaus ntawv ua ntej txuas ntxiv ua ntu zus. (Ntxiv rootwait hloov chaw rootdelay yuav txhais tau tias nws yuav tos tas mus li.)

Tom qab sim ua txhua yam sib xyaw ua ke ntawm SD daim npav thiab hard disk partitions Kuv tau txiav txim siab kom ua qhov faib me me rau ntawm SD Card thiab txav cov hauv paus thiab cov neeg siv cov ntaub ntawv mus rau hard disk. Cov txheej txheem los ua qhov no yog qhov ntev thiab yog raws li tau piav qhia hauv qhov txuas ntawm qhov kawg.

Duab 11 yog screendump ntawm qhov tshwm sim ntawm df -h ntawm kuv Pi, thiab qhia tau tias /dev /sda1 yog lub hauv paus cov ntaub ntawv kaw lus, /dev /sda2 muaj kuv cov neeg siv cov ntaub ntawv, thiab cov khau raj muab faib tseem nyob ntawm SD Card.

Kuv hais qhia tias koj yuav tsum xub sim ua kom khau raj txhua yam los ntawm lub hard disk vim qhov no tsuas yog koom nrog ua ob daim duab - ib qho ntawm SD Card, ib qho ntawm lub hard disk, thiab tom qab teeb tsa Pi lub khau raj xaiv fuse. Nco ntsoov tias Pi tseem yuav tuaj yeem khau raj ntawm SD daim npav yog tias lub fuse tau teeb tsa - qhov sib txawv tsuas yog tias tam sim no nws tau xub sim khau raj los ntawm USB disk tsav. Yog tias koj tsis tuaj yeem khau raj thaum xub thawj los ntawm hdd ces khau raj los ntawm SD daim npav thiab txuas thiab txuas lub hdd, tom qab ntawd kho ob daim ntawv teeb tsa raws li tau piav qhia yav dhau los ntawm hdd boot partition thiab sim rov pib dua.
