此文件是本人在实际项目中使用的文件: 使用方法如下 1、调用:I2C_Init() 初始化AD5612的引脚 2、输出想要的电压时:Write_AD5612IIC_REG(channel,DAC_IIC_0500V); 参数:channel 表示哪个AD芯片输出,因为我项目里有四个 参数:DAC_IIC_0500V 是我定义的表示0.5V电压的宏定义 ,如下 #define DAC_IIC_0500V 171 宏定义计算方法:Vout/3*1024。比如想输出0.6V,那么宏定义=0.6/3*1024=204.8可以取204或者205

Media Gateway 用于监控车载以太网通信,以太网端口测试,CAN/LIN/Flexray与100Base-T1路由测试等;在BMW,AUDI,BOSCH以及国内多公司大量使用; MediaGateway from Technica Engineering is a development tool for testing and analyzing on-board vehicle networks. MediaGateway from Technica Engineering is the most widely used development and testing tool for on-board vehicle networks using 100BASE-T1. It’s in-built automotive switches and 12 x 100BASE-T1 ports enable both capture of traffic between devices while maintaining the normal communication, as well as interaction with such devices via your test set-up. It supports single and double tagging of VLANs, Mirroring, Forwarding and more. MediaGateway is excellently suitable for subsystem testing stations and can also be installed in a test vehicle without complications. It is configured conveniently via a browser through the integrated web server. An additional and optional CAN-Ethernet bi-directional conversion is available, as well as FlexRay logging via Ethernet and one SFP slot. The SFP slot supports commercial-grade SFP modules (e.g. optical or RJ-45) as well as our 100BASE-T1 SFP Module in order to get a 13th Automotive Ethernet Port or our 1000BASE-T1 SFP Module – this makes the MediaGateway ready for Automotive Gigabit Ethernet! 12 Broadcom 100BASE-T1 ports (100 MBit/s full duplex on a single unshielded twisted pair) 3 Gigabit Ethernet ports 1 SFP Gigabit Ethernet port Automotive Tyco MQS connectors for 100BASE-T1 and power supply Web server for easy configuration: Master/Slave, HalfOut/FullOut, Port Forwarding, Port Mirroring, VLAN Tagging WakeUp function by CAN Bus or Wakeline Power output for attached devices: VBAT max. 1 Ampere in total 19 status LEDs Possibility to reset to default settings by pushbutton Robust steel case Power requirement: 8 to 16 V DC, power consumption: 8 Watt Size: 195 x 143 x 33 mm 802.1AS Bridge function

neo4j企业版 5.10.0 windows 版本 neo4j企业版 5.10.10 linux版本,企业版与社区的差别很大,主要有: 1、容量:社区版最多支持 320 亿个节点、320 亿个关系和 640 亿个属性,而企业版没有这个限制; 2、并发:社区版只能部署成单实例,不能做集群。而企业版可以部署成高可用集群或因果集群,从而可以解决高并发量的问题; 3、容灾:由于企业版支持集群,部分实例出故障不会影响整个系统正常运行; 4、热备:社区版只支持冷备份,即需要停止服务后才能进行备份,而企业版支持热备,第一次是全量备份,后续是增量备份; 5、性能:社区版最多用到 4 个内核,而企业能用到全部内核,且对性能做了精心的优化; 6、支持:企业版客户能得到 5X10 电话支持(Neo4j 美国电话、邮件,微云数聚电话、微信、邮件); 6、插件:还有企业版可以使用Bloom、ETL这些工具,社区版不支持
