我想知道何时有人打电话,从电话中收到的信号会是什么样?
我正在学习将集成在开发SIM模块(例如SIM800C)中的微控制器的代码重写,以便能够控制设备而无需使用其他MCU。如果我们可以做到这一点,我们只需要添加1个晶体管即可控制一个和关闭的继电器。 我知道,在SIM模块(例如SIM800C)内的MCU(例如STM32F ...)的输出中,将有一个函数可以接收和读取存储在SIM卡中的个人信息,并解码从移动基础站发出的信号:例如,当呼叫进来时,它将生成序列: 戒指 +剪辑:“ 01203360211”,161,“”,0,“”,0 ... 那么谁能帮助我知道MCU何时输出像上面的字符串,其输入11110000是什么?还是某种形式的特殊内容?我真的很困惑。谢谢大家!
I am learning to rewrite the code for the microcontroller integrated in the development Sim modules (such as Sim800C) to be able to control switching a device without having to use another MCU. If we can do that, we only need to add 1 transistor to be able to control a relay on and off.
I know at the output of the MCU (eg STM32F...) inside the sim module (eg sim800C) there will be a function to receive and read personal information stored in the sim card and decode the signal emitted from the Mobile base station: For example, when a call comes in, it will generate the sequence:
RING
+CLIP: "01203360211",161,"",0,"",0
....
So can anyone help me to know when the MCU outputs a string like the above, what will be its input 11110000,...? or something special in some form? I'm really confused. Thanks everyone!
