采用开源工具进行51单片机程序开发和仿真-【1】 - 知乎传统上，51单片机一般用keil c集成环境来进行编译开发，然后直接烧录到芯片上去运行，这有几个缺点： keil C是商业软件，很多人使用并不付钱，而是要么使用盗版（破解版），要么使用它的演化版（evolution version…https://zhuanlan.zhihu.com/p/370590579

51单片机(STC89C52)在Ubuntu下的开发-电子工程世界简介都是8051衍生的8位单片机, STC单片机有89 90 10 11 12 15这几个大系列, 每个系列的特点如下89系列是传统的8051单片机, 烧录方法有区http://news.eeworld.com.cn/mcu/ic618309.html
