Proces vývoje
1. Ujasněte si celkové hardwarové požadavky, jako je kapacita zpracování CPU, kapacita úložiště a rychlost, umístění I/Oportálu, požadavky na rozhraní, požadavky na úroveň a požadavky na speciální obvody atd.
2.Developanoverallhardwareplanbasedondemandanalysis,seekforkeycomponentsandtheirtechnicaldata,technicalapproaches,andtechnicalsupport.Itisnecessarytofullyconsidertechnicalpossibilities,reliabilityandcostcontrol,andtodevelopThedebuggingtoolputsforwardclearrequirements,andsamplesofkeycomponentsarerequested.
3.Proveďte podrobný návrh hardwaru, včetně kreslení hardwarových schémat, jednodeskových funkčních blokových diagramů a kódování, zapojení PCB a dokončení vývojových účtů materiálů, výrobních dokumentů (Gerber) a aplikací materiálů.
4.AfterreceivingthePCBboardandmaterials,arrangetoweld2~4singleboardsforsingleboarddebugging,commissioningeachfunctionintheprincipledesign,modifytheschematicdiagramandrecordifnecessary.
