In most cases, yes. However, you should consider that last year 2 8051-compatible devices were added each week of the year (100 per year). It takes about 1 month to add complete peripheral simulation support for a new device. If a totally unique device is created, it requires a minimum...
8051的时钟有两种方式,一种是片内时钟震荡方式,需在这两个引脚之间接石英晶体和震荡电容(一般取10p~30p),一种是外部时钟方式,即将XTAL1接地,外部时钟信号从XTAL2脚引入。 (外接晶体震荡电路) 2.单片机内部组成(STC宏晶科技 嵌入式单片机系统架构图片 寄存器 标识符 宏定义 转载 技术极先锋 2023-11-07 05:...
