For advanced geometry, most apps will prefer to load pre-authored
meshes from a file. Fortunately, when using meshes, D3DX does most of
the work for this, parsing a geometry file and creating vertx buffers
for us. This tutorial shows how to use a D3DXMESH
object, including loading it from a file and ...
模拟电子 意法半导体运放稳定性
 
Who has never experienced oscillations issues when using an operational amplifier? Opampsare often used in a simple voltage follower configuration. However, this is not the bestconfiguration in terms of capacitive loading and potential risk of oscillations.Capacitive loads have a big impa ...
单片机编程 Atmel AT89C系列单片机电路板设计指南
Designing Boards with Atmel AT89C51,AT89C52, AT89C1051, and AT89C2051 for Writing Flash at In-Circuit Test.
Recent improvements in chips and testers have made it possible for the tester to begin taking over the role tradi-tionally assigned to the PROM program-mer. Instead of having a PROM pro- g ...
