Xyoo 2001, tus kws kos duab thiab tus tsim qauv Raphael Abrams tau mus nrhiav qhov nyuaj tshiab. Tom qab qee qhov kev txiav txim siab ntev thiab ceev faj, nws tau los txog lub tswv yim ntawm kev tsim qauv thiab tsim nws tus kheej qhib qhov khoom siv mp3 player. Nws cov txheej txheem? Ua ntej, nws yuav tsum yooj yim los tsim. Qhov thib ob, nws yuav tsum tau qhib cov khoom siv. Thaum kawg, thiab tseem ceeb tshaj, nws yuav tsum yog ntau dua li tsuas yog lub cuab yeej siv tes - nws yuav tsum txuas tau yooj yim rau ntau qhov cuam tshuam, txhua yam los ntawm khawm yooj yim thawb mus rau cov chaw nres nkoj sib luag mus rau cov qauv muaj zog heev. Koj tuaj yeem yuav cov khoom siv los ntawm MAKE khw. Cov lus qhia no dhau los ntawm kev tsim kho thiab teeb tsa software rau kev ua haujlwm yooj yim rau 1.3 version ntawm Daisy cov khoom siv. Koj nyob nraum dawb los ua dab tsi txias koj tuaj yeem xav nrog cov cuab yeej siv tau ntau yam no! Txhawm rau kom nyob nrog lub ntsiab lus qhib, Songbird yuav yog software pob tau piav qhia hauv. Thov tawm tswv yim txog yuav ua li cas Cov Lus Qhia no yuav tsum txhim kho. Cov ntaub ntawv yuav ua li cas yuav sai sai no! Cov lus qhia hu qhov no "yooj yim tsim" ntaus ntawv, thiab thaum nws tsis yog lub hli hli, nws xav tau qee qhov txuj ci (z). Qhov teeb meem tshwj xeeb yog nrog kev teeb tsa saum npoo av. Nws yooj yim yog tias koj ceev faj thiab paub tias koj tab tom ua dab tsi. (Muaj cov kab laug sab nyias nyias thiab xaum zoo li tus xaum tooj dag lub taub hau yeej pab tau ib yam nkaus!) Txhawm rau kawm cov hauv paus ntawm kev siv tshuaj xyuas kos tawm phau ntawv qhia no zoo los ntawm noahw. Tsis tas li, ntawm no yog cov vis dis aus zoo los ntawm MAKE blog. Koj yuav tsum tau nyeem thawj cov lus qhia txog kev txhim kho saum npoo yog tias koj tsis tau ua tiav. Nws tsis yog qhov nyuaj. Hauv lwm lo lus, cov khoom uas tseem tsis tau hais txog yuav tshwm rau ntawm lub rooj tsavxwm. Thaum tso qhov no ua ke Kuv tau ua nws tawm ntawm qhov kev txiav txim zoo tshaj plaws (tsis txhob nug!). Yog li tsuas yog ua raws cov ntawv sau ntawm cov duab thiab koj yuav tsum yog qhov zoo tshaj plaws!

Kauj Ruam 1: Yam Koj Tau Txais thiab Yam Koj Xav Tau

Nrog rau cov khoom siv no koj yuav tau txais raws nraim 10, 000 ntu, uas muaj npe hauv qab no. Hmoov zoo, txawm li cas los xij, koj tsis tas yuav yuav ntau yam kom nws ua haujlwm. Lub cim xeeb flash Daisy siv yog Securedigital (SD) lossis MMC (Multimedia card (??)). Ib qhov zoo yog tias cov khoom siv no los nrog phau ntawv qhia, uas muaj cov duab zoo nkauj thiab piav qhia txog cov khoom. Koj tuaj yeem tau txais qhov kev daws teeb meem siab PDF ntawm no. Koj tau txais dab tsi: Bent tus pin tuav - yob loj lojVS1011 tus lej txiav txim siab - me me ic40 tus pin DIP qhov ntsaws - rau qhov loj ICSD/MMC Qhov (socket) 1 100 microF qis ESP capacitor - "c6" 2 100 microF capacitor - "c_l thiab c_r" 1 10 microF low ESP capacitor - "c4" 1 PCB1 lub mloog pob ntseg nkaus 12.1 microF capacitors - "c1, c2, c3, c5, c7, c8, c10, c11, c12, c13, c14, c15" (Tsis yog C4) 4 22 pF capacitors - "c3A, c3B, C4a, c4B" 1 swb hloov 1 LED1 PIC18F45j10 IC3 10K resistor tes hauj lwm - "RN1, RN2, RN3" 2 cov nplais cim 24.576 (cim cim) thiab 10.02 1K resistors - "r1, r2 "(xim av, dub, liab, kub) 1 1M resistor -" r3 "(xim av, dub, ntsuab, kub) 2 15ohm resistor -" r8, r9 "(xim av, ntsuab, dub, kub) 3 10K resistor -" r4, r6, r7 "(xim av, dub, txiv kab ntxwv, kub) 1 22K resistors -" r5 "(liab, liab, txiv kab ntxwv, kub) 1 teeb ntawm tus pin ncaj headers1 3.3 volt regulator 4 diodes -" D1 -D4 "" Dab tsi qhov koj xav tau: 3 AAA roj teeb muaj peev xwm SD lossis MMC flash nco Lub computer nrog SD nyeem ntawv ntawm qee yam esWhat cov cuab yeej koj xav tau: SolderSoldering ironWire clippersTable vicePliers (yeem, tab sis lawv zoo nkauj heev)

Kauj ruam 2: Nto Mounting Shock

Ua tus IC me dua, CS1011, ua ntej, vim nws nyuaj tshaj plaws. Taw qhia nws kom raug los ntawm tus teev nyob rau hauv lub ces kaum (saib cov duab kom ntxaws).

Nov yog cov lus piav qhia yooj yim ntawm kev teeb tsa saum npoo: yam tsis tau muab ib yam dab tsi tso rau ntawm lub rooj tsavxwm, ua kom sov cov neeg sib cuag nrog cov hlau txuas thiab muab me me los txhuam rau ntawm lawv. Thaum koj tau ua tiav tso cov khoom tiv toj rau ntawm kev sib cuag thiab ib ntawm ib qho, ua kom sov txhua qhov kev sib cuag nrog koj cov hlau txhawm rau txhawm rau txhawm rau txhawm rau txhawm rau tiv thaiv. Ua qhov no ua tib zoo siv koj lub sijhawm kom tsis txhob lo rau ntawm nws tus kheej. Tej zaum nws yog lub tswv yim zoo los ua txhua qhov saum npoo av ua ntej lwm yam khoom siv. Ua MMC/SD lub qhov (socket) thiab lub tso suab tso suab.

Kauj Ruam 3: Capacitors

Raws li cov lus qhia hauv phau ntawv qhia, ua cov capacitors tam sim no. Cov ntawd yog lub tsho daj, lub tsho xiav tsaus, thiab cov khoom loj. NCO TSEG: C4 tsis yog lub capacitor daj. Tsis txhob nce ib qho hauv C4, lossis nws yuav ua rau koj mob taub hau. C4 yog 10 uF capacitor. Koj yuav tsum tau khoov tus pin ib txoj hauv kev kom nws nce nrog qhov tsis zoo xaus rau sab xis. (Cov kab txaij dawb ntawm nws lub cev ntsej muag). Saib cov duab kom paub meej.

Kauj ruam 4: Resistors + Resistor Networks

Tom ntej no yog cov resistors thiab resistor tes hauj lwm, cov loj daj yam.

Qhov no yog txhua yam ncaj ncaj rau pem hauv ntej, tab sis ceev faj kom ntxig cov tes hauj lwm kom raug. Muaj qhov me me luam tawm ntawm txhua lub network, uas yuav tsum ua kom haum cov ntawv qhia ntawm PCB. Siv cov lus piv txwv hauv phau ntawv qhia kom paub tseeb tias koj tsis tau ua yuam kev.

Kauj Ruam 5: IC Qhov (Socket) thiab Lwm Yam

Cov kauj ruam no yuav ntev, vim nws yog qhov khoom kawg. Tam sim no muab tso rau ntawm IC qhov (socket), muaju, tswj qhov hluav taws xob, hloov, diodes thiab LEDs. Thiab lub jumper (saib hauv qab). Txhua yam muaju: Muaj ob, thiab ib qho muaj tus cim rau ntawm nws. Qhov ntawd yog 24Mhz siv lead ua thiab lwm qhov yog 10 Mhz siv lead ua. Txog diodes: Lawv yuav tsum tau taw qhia raws li cov cim ntawm PCB. Muaj kab tsaus nti ntawm txhua tus, uas yog qhov tsis zoo xaus. Khoov cov xov hlau kom nws haum, tab sis ua raws li kev taw qhia. (Saib daim duab). Hais txog LEDs: LEDs yog polarized, yog li cov lus qhia tseem ceeb. Luckily PCB tau muaj cov lus qhia nkag rau. LEDs tsis zoo tag nrho, muaj ib feem ncaj, uas yog qhov tsis zoo kawg. Sib phim qhov ntug ncaj rau daim duab ntawm lub rooj tsavxwm. (Saib daim duab) Jumper: Tej zaum koj tau pom SJ1 kev sib cuag ntawm lub rooj tsavxwm. Koj yuav tsum txiav me ntsis xaim ntev txaus kom haum rau ob qho tib si los ntawm ib qho ntawm cov khoom siv. Nto Mount cov hlau kom SJ1 txuas. Qhov no tau ua haujlwm sib txawv hauv cov ntawv dhau los ntawm pawg thawj coj.

Kauj Ruam 6: Header Pins & Ua tiav

Daisy MP3 player yuav tsum tau ua tiav tam sim no.

Muaj cov jumper pins koj xav tau tso rau. (Saib daim duab) Tsuas yog lo lawv nrog tus pin ntev dua. Thiab ham li qub. Koj yuav tsum muab tshuaj txhuam rau ntawm lwm lub taub hau yog tias koj xav siv lawv rau qee yam. 3 koj yuav xav tau lub hwj chim yog nyob ntawm yeem, nws tiag tiag nyob qhov twg koj xav tso cov khoom no. Qhov ntev header pin array yog rau kev tswj hwm lub suab paj nruag (nres, ntim khoom, thiab lwm yam). Txhua yam khoom ntawd tau piav qhia meej hauv phau ntawv qhia. Txhawm rau ntsuas nws tawm txuas hauv av (BLACK) mus rau GND lub davhlau ya nyob twg, thiab RED rau +5. LEDs yuav mus.

Kauj Ruam 7: Software thiab SD/MMC

VS1011 nti yuav lis txhua hom mp3 cov ntaub ntawv. Txheeb phau ntawv qhia kom ntxaws txog txhua qhov ntawd. Yeej, koj tso qee cov ntaub ntawv ntawm SD daim npav, thiab cov neeg ua si yuav ua lawv. Koj tuaj yeem hloov tus dhia (ZYXW) kom tau txais kev ua haujlwm sib txawv. Nco ntsoov tias koj xav tau daim npav SD, tab sis micro SD nrog lub adapter ua haujlwm tau zoo. Ua haujlwm no nrog OpenSource player zoo li Songbird yog qhov yooj yim, thiab koj tseem tuaj yeem hnov qee lub suab nkauj txias tshiab. Tau txais qhov tseeb Songbird los ntawm nws lub xaib. Songbird zoo ib yam li iTunes, tab sis nws lub webbrowser txhais tau tias nrhiav txhua hom nkauj. Thiab thaum nws pom cov nkauj nws suav nrog txoj cai rau hauv cov neeg ua si. Txhua lub suab paj nruag koj rub, tsuas yog luam nws mus rau koj daim npav SD/MMC. Muab lo rau hauv tus neeg ua si thiab koj tau teeb tsa!
