Ponena za zigawo za digito zikukhudzidwa, choyamba kudziwa zinthu zitatu mu dongosolo:

1) Tsimikizani kuti mfundo zonse zamagetsi zimakwaniritsa zofunika zapangidwe. Makina ena okhala ndi magetsi angapo angafunikire kutanthauza malamulo enawo ndi kuthamanga kwa magetsi.

2) Tsimikizani kuti zojambula zonse zotchinga zikugwira bwino ntchito moyenera ndipo palibe zovuta zomwe sizikhala zovuta m'mphepete.

3) Tsimikizani ngati chizindikiro chobwezeretsanso chimakwaniritsa zofunikira.

Ngati izi ndizabwinobwino, chip iyenera kutumiza chinsinsi choyamba (kuzungulira) chizindikiro. Kenako, debug malinga ndi mfundo yogwira ntchito ya dongosololi ndi protocol.

2. Pankhani ya kukula kwa madera okhazikika, ngati ntchito zambiri zikufunika kuti zikhale zopangidwa ndi PCB yowonjezerapo, koma nthawi yomweyo, mapangidwewo alibe mafuta ocheperako, koma nthawi yomweyo.

Mukamapanga ma pcbs apamwamba ndi osokoneza bongo, zosokoneza crostalch (Crostalk)) zimafunikira chisamaliro chapadera, chifukwa chimakhudza kwambiri nthawi ndi kusanja kwa nthawi. Nawa mfundo zochepa kuti mudziwe:

1) Sinthani kupitilizabe ndikufananitsa kwa kuwonongeka kwa chiwongola dzanja.

Kukula kwa nthawi yoyambira. Nthawi zambiri zimawoneka kuti nthawi yayitali mzere mzere. Ndikotheka kudziwa chifukwa cha kuchuluka kwa nthawi yoyeserera nthawi ndi siginecha kudzera mu fanizo, ndikupeza malo ochepera olekerera. Zotsatira za zizindikiro zosiyanasiyana zitha kukhala zosiyana.

2) Sankhani njira yoyenera yoyenera.

Pewani zigawo ziwiri zoyandikana ndi njira yolumikizira, ngakhale pakakhala ma wirkengs omwe amadzaza wina ndi mnzake, chifukwa mbewu zamtunduwu ndizokulirapo kuposa zomwe zimayandikana nawo.

Gwiritsani ntchito mitundu yakhungu / yakhungu kuti muwonjezere malo oyendera. Koma mtengo wopanga wa PCB board uge. Ndizovuta kuti mukwaniritse zofananira ndi kutalika kofanana mu kukhazikitsa kwenikweni, koma ndikofunikirabe kutero.

Kuphatikiza apo, kuchepa kosiyanasiyana ndi njira yodziwika bwino imatha kubwezeretsa zomwe zingasokoneze nthawi ndi kusanja.

3. Kusefedwa pa magetsi a Analog nthawi zambiri kumagwiritsa ntchito dera la LC. Koma chifukwa chiyani zosefera za LC zikuipiraipira kuposa RC nthawi zina?

Kuyerekezera kwa LC ndi RC kusokoneza kumayenera kuona ngati gulu la pafupipafupi kuti lisasewere komanso kusankha kusinthika ndikoyenera. Chifukwa chisinthidwe cha intuctor (mobwerezabwereza) chikugwirizana ndi phindu la chizolowezi komanso pafupipafupi. Ngati phokoso lamphamvu la magetsi lili lotsika, ndipo phindu lalikulu silakwela kokwanira, zosefera sizingakhale zabwino ngati RC.

Komabe, mtengo wogwiritsira ntchito RC ndikuti zokuza zomwe zimadya mphamvu ndipo zimagwira bwino ntchito, ndikusamala za mphamvu yomwe munthu wosankhidwa angathe kupirira.
