Cov txheej txheem sau rau hauv cov lus qhia no tuaj yeem siv los ua cov laug cam rau koj li kev xav tau ntawm txoj haujlwm.

Thov Saib Cov Video Kom nkag siab zoo

Muaj peb ntu hauv qhov kev qhia no.

1. Tsim thiab sib sau tag nrho cov Cheebtsam

2. Hlawv Boot-loader mus rau Chip tshiab

3. Uploading Test Code

Kuv Tau Txuas Cov Ntaub Ntawv PCB tom kawg ntawm kab lus no.

Yog li cia peb Pib!

Daim duab kos Circuit Court thiab PCB txheej txheem tau rub los ntawm Arduino Lub Vev Xaib. Tom qab ntawd kuv hloov kho me ntsis raws li txhua yam khoom siv hauv thawj lub rooj tsavxwm tsis muaj nrog kuv. Kuv xaj Circuit Board hauv online.

Thaum tau txais PCB, Kuv tau siv kuv lub tshuab cua tshuab cua tshuab cua sov los txhawm rau txhawm rau txhawm rau cov khoom siv thiab ICs. Cov duab ntawm pawg thawj coj ua tiav tau txuas nrog.

Kuv tsis tau piav qhia cov txheej txheem txheej txheem tam sim no vim nws yog lub ncauj lus ntawm kev nthuav dav rau kev qhia sib txawv. Kuv Thov siv cov tshuaj txhuam lo rau ntawm PCB siv stencil, Muab cov khoom sib txuas, thiab siv cov tshuab cua kub cua tshuab.

Cov Txheej Txheem Txhawm rau hlawv Boot loader tom qab ua qhov sib txuas raug.

1) Txuas Arduino NANO rau USB ntawm koj lub PC

2) Xaiv lub Rooj Tswjhwm Saib tsim nyog thiab Com Port

3) Hauv cov cuab yeej ntawv qhia zaub mov xaiv ARDUINO AS ISP Programmer. Txoj hauv kev: Cov cuab yeej> Programmer> Arduino Raws li ISP

4) Mus rau Cov Cuab Yeej thiab xaiv Hlawv Boot Loader. Txoj hauv kev: Cuab Yeej> Hlawv Boot Loader

5) Qhov no yuav siv sijhawm txog ib pliag thiab cov lus "Ua Tiav Hlawv Boot Loader" yuav tshwm.

Tom qab qhov no koj tuaj yeem tshem tag nrho cov xov txuas thiab txuas thiab koj tus AVR Micro-Controller tshiab tau npaj los siv ua khoom siv ib leeg rau koj cov haujlwm.

*Txhua daim duab yog ua raws li txheej txheem

1) Txheeb xyuas koj cov Circuit sib txuas thiab cov khoom siv (feem ntau yog Crystal) yog tias hlawv Boot loader tsis ua haujlwm.

2) Nco ntsoov tias koj tau hais txog lub rooj tsavxwm raug thiab COM chaw nres nkoj hauv software

3) Txheeb xyuas qhov ua tsis raug USB Cable.

4) Yog tias Micro Controller kub dua thaum siv zog tej zaum koj muaj IC tsis raug.

5) Txheeb xyuas txuas ntxiv hauv PCB thiab cov laug tsis xav tau txuas thaum peb siv SMD Cheebtsam.
