一个i2c主设备fx2lp和fx2lp18可以驱动多少个i2c从设备？

它能支持128个奴隶。包含从属地址的字节决定哪个从属，数据指向。
当做，

  It can support upto 128slaves. The byte that contains the address of the slave determines which slave, the data is directed to.

一个主人可以驾驶256个奴隶？实际上是真的吗？



     以下为原文
  A single master can drive 256 slaves?is it true practically?

你好，
对不起，我之前的回答有错误。在寻址的8位中，一位决定I2C传输是读还是写。从理论上讲，它是2 ^ 7＝128奴隶。（我已经编辑了我以前的256到128的回应来避免混淆），但是实际上你不能一次连接128个奴隶，因为负载太多了。所以，如果你有合适的电路，连接128个奴隶是可能的。



     以下为原文
  Hi,
 
Sorry, there is a mistake in my previous response. Out of the 8 bits for addressing, one bit decides whether the i2c transfer is read or write. So it is 2^7 = 128 slaves theoretically. (I have edited my previous response from 256 to 128 to avoid confusion) But you cannot connect 128 slaves at a time practically because the load will be too much. So if you have appropriate circuitry, it is possible to connect 128 slaves.

非常感谢你，
你所说的适当电路是什么意思？
没有合适的电路，我们能连接8个从设备吗？
什么是最大的从属设备可以连接没有任何电路？



     以下为原文
  thank you so much,
what you mean by appropriate circuitry?
without appropriate circuitry,can we connect 8 slave devices?
what is the maximum slave devices can connect without any circuitry?
