Suab paj nruag Synthesizer

Tus tsim cov nkauj no yooj yim heev: koj tsuas yog yuav tsum tshuab, hu nkauj, lossis txawm tias ua suab paj nruag nyob rau pem hauv ntej ntawm lub microphone, thiab lub suab yuav raug hloov pauv thiab xa los ntawm tus hais lus. Nws cov specctrum kuj tseem yuav tshwm ntawm lub vijtsam LCD. Qhov Suab Nkauj Synthesizer muaj nyob hauv ob qho qauv: koj tuaj yeem xaiv siv nws ntawm PCB, lossis yog tias koj ua tsis tau, Breadboard yooj yim yuav ua.

Kauj Ruam 1: Cov Khoom Xav Tau thiab Cov Lus Qhia

Thov nco ntsoov tias koj yuav xav tau cov khoom siv ntau dua li qhov xav tau.

Peb kuj pom zoo kom muaj kev paub pib hauv hluav taws xob thiab SoC tsim ua ntej pib qhov haujlwm no

Kauj Ruam 2: Tau Txais Pawg Thawj Coj

Tam sim no koj tau txais txhua yam koj xav tau, cia pib los ntawm kev ua lub rooj tsav khoom. Lub microphone sau cov suab nyob ze, tom qab ntawd lub teeb liab tau lim los ntawm cov lim qis kom thiaj ua piv txwv nws (thiab yog li hwm Shannon theorem) ua ntej nws nthuav dav thiab thaum kawg kaw los ntawm DE0.

Yog tias koj paub nrog Altium Tsim Software thiab nkag tau rau PCB tus kws kos duab, koj tsuas yog yuav tsum tsim cov txheej txheem uas tau qhia hauv daim duab saum toj no, thiab tso cov khoom sib xws raws li peb tau ua hauv daim duab thib ob. Txwv tsis pub, koj tsuas tuaj yeem rov tsim lub voj voog no ntawm lub khob cij.

Hauv ob qho tib si, qhov tseem ceeb ntawm cov resistors, pom tseeb muab hauv Ohms, thiab qhov tseem ceeb ntawm cov capacitors, muab hauv Farads, yog raws li hauv qab no:

• R4: 2,2 ib
• 5: 10k wb
• R6 thiab R7: 100
• 3: 470 ib
• R1 thiab R2: 18 (cov resistors no tau siv los kho qhov hluav taws xob tso tawm uas yuav tsum yog 2V yog li cov txiaj ntsig no yuav txawv me ntsis rau koj)
• R8: 1.8k ib
• R9: 1 mav
• R10: 150
• R11, R12, R14 thiab R15: 1.5k
• Kaum Ob Hlis 1: 2.2µ
• Kaum Ob Hlis 2: 100µ
• Hnub 3: 100n
• Hnub 4: 1µ
• Dec 5, Dec6, Dec7, Dec8, Dec9, Dec 10, Dec 11, Dec 12, Dec 13, Dec14: 1µ
• Dec 15: +1000µ (4400 piv txwv)
• C1: 10 hli
• C2: 1 ua
• C3 thiab C4: 100n
• C5: 1 ua

Peb tau ua tiav nrog pawg tswj hwm kev yuav khoom!

Kauj Ruam 3: Lub Rooj Tswjhwm Saib Cov Suab

Muaj peev xwm sau cov suab yog qhov zoo, tab sis muaj peev xwm rov tsim dua lawv txawm tias zoo dua! Yog li, koj yuav xav tau lub suab tso tawm suab, tsuas yog suav nrog cov hloov pauv digital/analog, lim dej kom huv, lub zog tso zis thiab tus hais lus.

Tau kawg, koj tseem tuaj yeem tsim cov Circuit Court ntawm PCB (thiab tso cov khoom sib xws raws li qhia hauv daim duab thib ob) lossis ntawm lub khob cij. Hauv ob qho tib si, ntawm no yog qhov txiaj ntsig rau ob lub capacitors thiab resistors:

• R1 thiab R2: 100
• R3 thiab R4: xov hlau
• R5: 10 ib
• C1: 1 µ
• C2, C3, C5, C6, C7, C9: 100µ (polarized)
• C4 thiab C8: 100n
• C10: 0.05 hli
• C11: 250 hli

Peb tau ua tiav nrog lub suab tso tawm, yog li cia peb txav mus rau software!

Kauj Ruam 4: Txoj Haujlwm Quartus

Txhawm rau ua tej yam yooj yim, peb txiav txim siab pib los ntawm "kuv thawj-hps-fpga" txoj haujlwm muab hauv CD-ROM suav nrog DE0-Nano-SoC. Txhua yam koj yuav tsum ua yog qhib txoj haujlwm no thiab pib "Platform Designer" lossis "Qsys" los ntawm cov cuab yeej bar, thiab rov tsim dua txoj haujlwm saum toj no. Tom qab ntawd, tsim cov qauv tsim thiab suav nrog Qsys (saib qhov ua qauv qhia kom paub ntau ntxiv).

Kauj ruam 5: Txaus siab rau

Tam sim no tias cov ntaub ntawv HDL tau tsim, koj tsuas yog xav tau los tsim qhov haujlwm Quartus. Fort lub hom phiaj ntawd, ntsaws lub USB cable rau hauv USB txuas (JTAG) ntawm DE0-Nano-Soc. Tom qab ntawd, xaiv Cov Cuab Yeej> Programming ntawm Quartus. Nyem rau Auto Detect, tom qab ntawd xaiv qhov kev xaiv thib ob. Tom qab ntawv, nyem FPGA ntaus ntawv (qhov thib ob), tom qab ntawd "Hloov cov ntaub ntawv" thiab xaiv cov ntaub ntawv.sof yav tas los tsim tawm. Thaum kawg, nyem "Program/Configure" check board thiab nyem "Start" khawm kom qhib cov ntaub ntawv.

Thaum kawg, xa cov lej C hauv qab no rau hauv DE0 nco. Rau lub hom phiaj ntawd, teeb tsa Putty ntawm lub PC (Linux), txuas lub rooj tsavxwm rau nws los ntawm kev txuas Ethernet thiab los ntawm ntsaws lub USB cable rau hauv USB txuas (UART) ntawm DE0. Tua tawm thiab teeb tsa Putty nrog tus nqi baud ntawm 115200, tsis muaj kev ncaj ncees, ib qho nres me ntsis thiab tsis muaj chaw tswj kev ntws. Tom qab ntawd, yuam tus IPv4 chaw nyob ruaj ntseg rau koj lub PC Ethernet chaw nres nkoj, nkag mus "hauv paus" ntawm Putty plhaub, tom qab ntawd "ifconfig eth0 192.168. XXX. XXX" thiab "tus lej" ua raws tus lej nkag. Qhib lub plhaub ntawm koj lub PC, mus rau qhov project repository, thiab sau "scp myfirsthpsfpga [email protected]. XXX. XXX: ~/". Thaum kawg, ntawm lub plhaub Putty, sau "./myfirsthpsfpga". Txaus siab rau!
