  • 安森美车规级1080P图像传感器AR0231手册

    AR0231AT7C00XUEA0-DRBR(RGB滤光)安森美半导体推出采用突破性减少LED闪烁 (LFM)技术的新的230万像素CMOS图像传感器样品AR0231AT,为汽车先进驾驶辅助系统(ADAS)应用确立了一个新基准。新器件能捕获1080p高动态范围(HDR)视频,还具备支持汽车安全完整性等级B(ASIL B)的特性。LFM技术(专利申请中)消除交通信号灯和汽车LED照明的高频LED闪烁,令交通信号阅读算法能于所有光照条件下工作。AR0231AT具有1/2.7英寸(6.82 mm)光学格式和1928(水平) x 1208(垂直)有源像素阵列。它采用最新的3.0微米背照式(BSI)像素及安森美半导体的DR-Pix™技术,提供双转换增益以在所有光照条件下提升性能。它以线性、HDR或LFM模式捕获图像,并提供模式间的帧到帧情境切换。 AR0231AT提供达4重曝光的HDR,以出色的噪声性能捕获超过120dB的动态范围。AR0231AT能同步支持多个摄相机,以易于在汽车应用中实现多个传感器节点,和通过一个简单的双线串行接口实现用户可编程性。它还有多个数据接口,包括MIPI(移动产业处理器接口)、并行和HiSPi(高速串行像素接口)。其它关键特性还包括可选自动化或用户控制的黑电平控制,支持扩频时钟输入和提供多色滤波阵列选择。封装和现状:AR0231AT采用11 mm x 10 mm iBGA-121封装,现提供工程样品。工作温度范围为-40℃至105℃(环境温度),将完全通过AEC-Q100认证。

  • 基于单片机的数字化B超键盘设计

    针对目前使用的RS232接口数字化B超键盘存在PC主机启动时不能设置BIOS,提出一种PS2键盘的设计方法。基于W78E052D单片机,采用8通道串行A/D转换器设计了8个TGC电位器信息采集电路,电位器位置信息以键盘扫描码序列形式发送,正交编码器信号通过XC9536XL转换为单片机可接收的中断信号,软件接收到中断信息后等效处理成按键。结果表明,在满足开机可设置BIOS同时,又可实现超声特有功能,不需要专门设计驱动程序,接口简单,成本低。 Abstract:  Aiming at the problem of the digital ultrasonic diagnostic imaging system keyboard with RS232 interface currently used couldn?蒺t set the BIOS when the PC boot, this paper proposed a design method of PS2 keyboards. Based on W78E052D microcontroller,designed eight TGC potentiometers information acquisition circuit with 8-channel serial A/D converter, potentiometer position information sent out with keyboard scan code sequentially.The control circuit based on XC9536 CPLD is used for converting the mechanical actions of the encoders into the signals that can be identified by the MCU, software received interrupt information and equivalently treatmented as key. The results show that the BIOS can be set to meet the boot, ultrasound specific functionality can be achieved at the same time, it does not require specially designed driver,the interface is simple and low cost.

  • design LP,HP,B S digital Butterworth and Chebyshev filter. All array has been specified internally

    design LP,HP,B S digital Butterworth and Chebyshev filter. All array has been specified internally,so user only need to input f1,f2,f3,f4,fs(in hz), alpha1,alpha2(in db) and iband (to specify the type of to design). This program output hk(z)=bk(z)/ak(z),k=1,2,..., ksection and the freq.
