国产以太网控制器CH390h试用体验----替代W5500
前言W5500是一款集成了TCP/IP协议栈的以太网控制器，广泛用于嵌入式系统中，以实现网络通信功能。它通过SPI接口与微控制器（如STM32）进行通信，支持TCP、UDP、ICMP、IPv4、ARP、IGMP和PPPoE等多种网络协议。在使用的过程中，发现W5500发热量很大，价格也不便宜，封装尺寸也比较大。由于网络上并没有太多相关替代产品的信息，个人在购买了DM9051和CH390h的模块并测试后，发现CH390h应该是更好的国产替代产品。一、实际产品对比照片...

STM32操作MAX197总结！
本帖最后由youki12345于2015-1-1020:15编辑 最近要做个AD采集的项目，AD输入为-5~+5v，采集的方法有很多种，比如说利用STM32自带的AD来做，但这样有个问题，负电压必须通过移位和衰减变成正的的才能符合STM32AD的量程范围，如果测量的过程中有一点偏差或者外围电路有一点小的问题造成AD获取的数据不准的话那最终反算出来的实际电压就会偏差比较大。所以在这次项目中我们考虑了MAX197。它的优点很多：1.单电源5V供电的...

【藏书阁】89S5X 并口下载线的制作
网友聂忠强写的89S5X下载线软件EasyPlay，其并口下载线的制作简单使用方便，下载的速度也很快，其稳定性也很不错。下面我把自已的制作经验用图解的形式和大家分享，同时感谢聂忠强网友无私的奉献。ISP(InSystemProgramming)技术即系统编程技术是指在用户设计的目标系统中或印刷电路板上，为重新配置逻辑或实现新的功能，而对器件进行编程或反复编程的能力。ISP技术无需编程器和较高的编程电压，打破了先编程后装配的惯例，形成产品后还可以在系统内反复编程，使具有MTP-ROM可多...

汽车电子行业杂谈
今天前同事请吃饭，一起很好的兄弟，一个学校，一个学院的校友，08年一起进的公司，刚跳槽去了整车厂，工资涨了不少，工作也算轻松。晚上见到了几个前同事，感叹一桌子人，半年前还都在一个公司，半年后一半都已经各奔东西了。09年初，是汽车产业最黑暗的时候，当时风声鹤唳，裁员的风声很紧，大半都是不续约走人的。当时走了不少兄弟姐妹，有转行的，有去别的类型公司的。稍微统计了一下，有三个兄弟姐妹去了整车厂，有五个人去了国有的零部件公司，有两人去了外资的零部件公司，一人去了私营的零配件公司，有三人转出了行业。0...

罗德与施瓦茨与三星世界上首个LTE-Advanced上行载波聚合的验证
罗德与施瓦茨公司的R&SCMW500测试仪又一次向世人展示了其不凡的无线测试能力。日前，罗德与施瓦茨公司和三星公司通过在真实样机上成功验证载波聚合特性。据悉，用于测试的三星DUT是一部6.3英寸的真实样机，DUT采用搭载三星SHANNON300modem芯片的测试终端；测试仪表采用罗德与施瓦茨公司的CMW500宽带无线通信测试仪，此次罗德与施瓦茨和三星的共同努力也使SHANNON300成为世界上第一颗成功验证LT...
