Nyob zoo tav su, cov saib thiab nyeem. Hnub no kuv xav qhia koj ua tiav kev qhia ua ke rau 10 band LED spectrum analyzer.

Kauj Ruam 1: Txheej txheem cej luam ntawm Cov Qauv Tshwj Xeeb ntawm Spectrum Analyzer

1. Qhov nqi nyeem yog nyob ntawm ntau zaus los ntawm peb caug-ib hertz mus rau kaum rau kilohertz.

2. Dimensions ntawm LED matrix: kaum kab ib kaum kab.

3. Muaj peev xwm ua haujlwm hom: teev, teev nrog ncov tuav, kab, kab nrog ncov tuav.

4. Qhov ntsuas ntsuas hluav taws xob tau siv los ntawm kaum ob volt DC fais fab mov.

5. Power noj yog nyob ntawm LEDs siv hauv matrix.

6. Type ntawm cov teeb liab tawm tswv yim: Tawm mono.

Kauj Ruam 2: Txuas mus rau Cheeb Tsam Xov Tooj Cua

Khaws nrog cov ntaub ntawv tsom xam cov ntaub ntawv txuas:

Txoj haujlwm ntawm nplooj ntawv EasyEDA:

Cov khoom siv xov tooj cua:

Microchip Atmega 8:

10 ntu LED module:

Kauj Ruam 3: Tsim Circuit Court

Qhov no 10-qhab LED lub suab ntsuas tshuab ntsuas muaj ob ntu-kev tswj luam tawm Circuit board thiab LED matrix luam tawm Circuit board.

Cov txheej txheem ntawm cov ntsuas hluav taws xob LED muaj xws li chav ua haujlwm ua haujlwm nrov, tswj microcontroller, binary rau decimal decoder, thiab PNP thiab NPN transistor hloov.

LED matrix muaj kaum tus qauv. Txhua tus qauv muaj kaum LEDs ntawm cov xim sib txawv.

Kauj Ruam 4: PCB Txheej Txheem

1. Txhawm rau pib teeb tsa cov ntsuas hluav taws xob LED, koj yuav tsum nrhiav kom paub ntau ntxiv txog kev tswj hwm daim duab qhia chaw thiab daim duab qhia chaw ntawm LED matrix los ntawm kev tso npe rau ntawm EasyEDA lub vev xaib lossis rub tawm cov ntawv khaws cia tom qab txuas hauv kab lus 2.

2. Ntawm EasyEDA lub vev xaib peb tsim cov ntaub ntawv Gerber los ntawm kev hloov pauv luam tawm cov laug cam ntawm cov tshuab ntsuas hluav taws xob rau kev tsim khoom ntxiv ntawm lub hoobkas.

3. Ua ntej yuav mus rau lub vev xaib raug cai ntawm cov chaw tsim khoom lag luam luam tawm, EasyEDA kev txhim kho ib puag ncig qhia peb cov ntaub ntawv luv luv txog cov yam ntxwv ntawm cov ntawv luam tawm Circuit board thiab tus nqi kwv yees li 10 daim.

4. Ntawm lub vev xaib ntawm lub chaw tsim khoom lag luam luam tawm JLCPCB cov ntaub ntawv tuaj yeem rub tawm ncaj qha los ntawm EasyEDA Gerber kev txhim kho ib puag ncig. Koj kuj tseem tuaj yeem siv cov ntaub ntawv Gerber tshwj xeeb los ntawm cov ntawv khaws cia thiab rub tawm lawv tus kheej.

5. Tom qab ntawv tso qhov kev txiav txim ntawm qhov chaw nyob uas raug xaiv thiab xaiv lub sijhawm xa khoom nyiam.

Cov ntawv xov xwm hluav taws xob luam tawm tau xa hauv lub thawv nrog lub npe ntawm lub khw. Sab hauv lub thawv ntawv cov ntawv xov xwm hluav taws xob luam tawm tau muab tais zoo rau hauv lub tshuab ntim khoom.

Kauj Ruam 5: Kev teeb tsa Cov Xov Tooj Cua ntawm Cov Tswj PCB

Cia peb npaj mus rau teeb tsa cov khoom siv xov tooj cua ntawm lub rooj tsav xwm tswj hwm.

Kauj Ruam 6: Kev teeb tsa Cov Xov Tooj Cua ntawm PCB ntawm LED Matrix

Tom ntej no, cia nruab ib lub rooj tsav xwm luam tawm ntawm LED matrix.

Kauj Ruam 7: Software thiab USB AVR Programmer

Cia peb mus txuas ntxiv mus rau software ib feem ntawm cov tshuaj ntsuam spectrum.

Txhawm rau hloov kho lub firmware ntawm Atmega 8 microcontroller peb yuav siv Atmel studio 7.

Koj tuaj yeem rub tawm dawb tag nrho version ntawm Atmel studio 7 los ntawm nom tswv Microchip Technology lub vev xaib.

https://www.microchip.com/mplab/avr-support/atmel-…

Txhawm rau txuas tus microcontroller rau lub khoos phis tawj peb yuav siv Pololu USB AVR Programmer.

Pololu USB yog ib qho kev cog lus me me thiab pheej yig hauv kev tsim hluav taws xob rau AVR-raws cov tswj hwm. Tus programmer ua raws STK500 los ntawm qhov chaw nres nkoj virtual, uas ua rau nws sib xws nrog cov software txheem xws li Atmel studio thiab AVR DUDE.

Tus khoos phis tawj tau txuas nrog lub hom phiaj siv siv 6-pin ISP cable. Tus programmer txuas nrog lub USB chaw nres nkoj ntawm USB Hom A rau Mini B cable, uas tseem suav nrog hauv cov khoom siv.

Txhawm rau ua haujlwm tag nrho ntawm tus programmer rub tus tsav tsheb los ntawm Pololu lub vev xaib raug cai.

https://www.pololu.com/product/1300/resources

Ntawm Pololu lub vev xaib mus rau Cov Chaw Pabcuam thiab xaiv cov ntaub ntawv tsim nyog nrog kev teeb tsa tsav tsheb thiab software rau lub Windows operating system.

Kauj Ruam 8: Microcontroller Programming

1. Tom ntej no, txuas ISP cable ntawm tus programmer thiab 5-tus pin txuas nrog cov xov hlau txuas nrog lub microcontroller ntawm daim ntawv luam tawm Circuit Board, thiab tom qab ntawd txuas tus programmer mus rau USB chaw nres nkoj ntawm koj lub computer.

2. Txhua ua ntej mus rau Start menu, xaiv lub tswj vaj huam sib luag, thiab tom qab ntawd xaiv tus thawj tswj ntaus ntawv hauv lub qhov rai uas tshwm.

3. Hauv tus thawj tswj hwm lub cuab yeej xaiv qhov Chaw Nkag tab. Ntawm no koj yuav tsum tau saib qhov chaw nres nkoj virtual uas tus programmer txuas nrog. Hauv kuv qhov xwm txheej, qhov no yog virtual COM chaw nres nkoj 3.

4. Tom ntej no, rov qab mus rau Start menu thiab xaiv cov programmer teeb tsa kev siv hluav taws xob.

5. Hauv lub qhov rai uas tshwm tuaj koj yuav tsum hloov lub moos zaus ntawm lub cuab yeej phiaj xwm. ISP zaus yuav tsum tsawg dua li peb lub hlis ntawm lub moos zaus ntawm lub hom phiaj AVR microcontroller.

6. Ntxiv mus, mus rau Cov Cuab Yeej tab thiab nyem 'Ntxiv lub hom phiaj'. Hauv lub qhov rai uas tshwm xaiv xaiv 'STK500' thiab 'virtual COM chaw nres nkoj 3'.

7. Tom qab ntawd mus rau Cov Cuab Yeej tab dua thiab nias 'Programming lub cuab yeej'.

8 Hauv lub qhov rai uas tshwm, qhov twg yog cov cuab yeej, xaiv 'STK500 COM chaw nres nkoj 3'. Ua ib lub cuab yeej rau kev ua haujlwm, xaiv Atmega 8 microcontroller. Tom ntej no, qhia ISP lub interface kev sib tham.

Qhov ISP zaus kuj tseem tuaj yeem teeb tsa hauv Atmel studio, tab sis cov zaus uas tau teev tseg hauv Atmel studio cov neeg siv sib cuam tshuam tsis sib xws nrog qhov tseeb zaus ntawm tus programmer siv.

9. Nyeem qhov hluav taws xob thiab kos npe ntawm lub cuab yeej phiaj xwm, tom qab uas mus rau Fuse-khoom tab thiab nyem rau ntawm lub npov raws li qhia hauv video. Sau cov txheej fuse-khoom hauv microcontroller lub cim xeeb.

10. Tom ntej no, qhib lub cim xeeb tab thiab xaiv HEX cov ntaub ntawv khaws cia hauv computer thiab tseem kaw nws hauv microcontroller lub cim xeeb.

Kauj Ruam 9: Txuas PCB ntawm LED Matrix thiab Tswj PCB

Tom qab tsim lub microcontroller thiab siv tag nrho cov khoom siv hauv xov tooj cua, cia peb txuas cov ntawv luam tawm Circuit Board ntawm LED matrix thiab tswj lub rooj tsav xwm.

Kauj Ruam 10: Kev Ua Haujlwm ntawm 10 Band Coj Spectrum Analyzer

Kauj Ruam 11: Xaus Kev Qhia

Ua tsaug rau txhua tus saib cov vis dis aus thiab nyeem kab lus. Tsis txhob hnov qab nyiam nws thiab sau npe mus rau "Hobby Home Electronics" channel. Qhia rau phooj ywg. Ntxiv mus yuav muaj cov kab lus thiab cov vis dis aus txaus nyiam dua.
