单片机编程 PCA9671 Remote 16-bit IO expan
The PCA9671 provides general purpose remote I/O expansion for most microcontrollerfamilies via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plus(Fm+) family.The PCA9671 is a drop in upgrade for the PCF8575 providing higher I2C-bus speeds(1 MHz versus 400 kHz) so that the o ...
单片机编程 PCA9672 Remote 8-bit IO expand
The PCA9672 provides general purpose remote I/O expansion for most microcontrollerfamilies via the two-line bidirectional bus (I2C-bus) and is a part of the Fast-mode Plusfamily.The PCA9672 is a drop-in upgrade for the PCF8574 providing higher Fast-mode Plus(Fm+) I2C-bus speeds (1 MHz versus 400 kHz ...

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 ...

技术资料 基于MSP430单片机及FPGA的简易数字示波器
数字示波器功能强大,使用方便,但是价格相对昂贵。本文以Ti的MSP430F5529为主控器,以Altera公司的EP2C5T144C8 FPGA器件为逻辑控制部件设计数字示波器。模拟信号经程控放大、整形电路后形成方波信号送至FPGA测频,根据频率值选择采用片上及片外高速AD分段采样。FPGA控制片外AD采样并将数据输入到FIFO模块中缓存,由单片机进行频 ...
