Разработка на хардуер

Процес на разработка

1. Изяснете общите хардуерни изисквания, като капацитет за обработка на CPU, капацитет за съхранение и скорост, разпределение на I/Port, изисквания за интерфейс, изисквания за ниво и изисквания за специални схеми и др.

2.Developanoverallhardwareplanbasedondemandanalysis,seekforkeycomponentsandtheirtechnicaldata,technicalapproaches,andtechnicalsupport.Itisnecessarytofullyconsidertechnicalpossibilities,reliabilityandcostcontrol,andtodevelopThedebuggingtoolputsforwardclearrequirements,andsamplesofkeycomponentsarerequested.

3.Извършване на подробен дизайн на хардуер, включително чертане на схематични диаграми на хардуер, функционални блокови диаграми и кодиране на една платка, PCB окабеляване и попълване на сметки за разработка на материали, производствени документи (Gerber) и приложения на материали.

4.AfterreceivingthePCBboardandmaterials,arrangetoweld2~4singleboardsforsingleboarddebugging,commissioningeachfunctionintheprincipledesign,modifytheschematicdiagramandrecordifnecessary.
