和单片机的TTL电平不一致,因此单片机和PC机之间的串口通讯必须要有一个RS232/TTL电平转换电路。通常这个电路都选择专用的RS232接口电平转换集成电路进行设计,如MAX232、HIN232等 奇迹物联2020-02-24 14:37:23 简单的RS232C/TTL电平转换和串口取电,RS232C--TTLconverter ...
This RS232 to TTL converter lets you connect devices that use RS232 serial ports to devices that only communicate using transistor-transistor logic (TTL) signals. It’s a convenient and cost-effective solution to convert RS232 into TTL, so you can connect equipment together based on your devic...
图三是另一种RS232/TTL电平转换电路,对于接收电路,它是和图一的电路是一样的。该电路用2个NPN小功率晶体管,转送电路不需要从RS232C的TxD引用负的电压,而这样做的话,当单片机TxD为高电平时RS232C的RxD为0V(不是如图一的-9V左右),为低电平时RS232C的RxD为+5V,显然这和RS232C的标准不同,但多数PC机串口可...
