This is the 7thtutorial in theAVR seriesusing the xplained mini development board, and today we will continue with the I2C Master series. In this series, we will developing the code for the I2c master across few tutorials, covering the Write and Read operations to the slave device. We have...

+ IMX_I2C_I2CR);DR中的(残留)数据就立即被送上I2C总线,无视之前或之后对DR的写入值.这与设计预期不符，这里该如何控制？我们预期是设置i2c为TX模式，写入I2DR寄存器后，数据才可以被送到I2C上。另外，当iMX6SDLRM的I2C控制器被设成Slave Mode,连接在I2C总线上,请问,你们有没有在Master Read会话...

Hi all, I'm using i2C port0 in a multi-master environment. Here's my situation: after I have received a byte from another master, I need to become master and
I based on freertos_i2c sample code in lpcxpresso66s28 SDK to develop my i2c slave program. However, I found if I don't add a delay between write and read commands, the master side will get wrong data from the slave side. The root cause is the slave side cannot...
I2c.read(address, numberBytes) Description: Initiate a read operation from the current position of slave register pointer. The bytes will be stored in an internal buffer and will have the 32 byte size restriction. Data can be read out of the buffer using I2c.receive(). Parameters: address ...
