The I2C address is 7-bits long. It is transmitted in the seven most significant bits (MSB). The last (eighth bit) of the I2C address byte is a data direction bit - a 'zero' indicates a transmission (I2C WRITE), a 'one' indicates a request for data (I2C READ). You have to speci...

在I2C协议中,寄存器地址(reg address)是一项重要的概念。寄存器地址用于在I2C设备内部的寄存器中标识特定的功能或数据。本文将逐步介绍I2C中的寄存器地址及其作用,以及在使用I2C通信时如何正确使用寄存器地址。 第一部分:什么是寄存器地址 I2C设备内部是由一系列寄存器组成的,寄存器是一块用于存储数据的特殊内存单元。寄存器...
I2C设备地址 TargetAddress 24LC04 说明 I2C 在总线上支持N-2-N,因此需要用地址来区分设备。 一次完整的传输,总是START起始信号之后紧跟设备地址和读写标志。 设备地址 那么设备地址如何查看和定义的呢? 设备地址对应 第一个BYTE的 BIT7-BIT1, BIT 0对应读写标志 I2C协议规定,除了 0000 XXX和 1111 XXX之外,其...

The original I2C address can be translated to the translated I2C address by subtracting an offset value from (or adding an offset value to) the original I2C address to produce the translated I2C address. Such an offset value can be specified using pin strapping, or by storing the offset ...

Below is an image when trying to address 0x38: Notice the ACK and that the communication continues. Using address = 0x38, I can control the outputs of the IO expander. Turns out that NXP makes an IO expander with the same exact pin out, but with and I2C address of 0x38, the PCF...
