Posted on March 02, 2014 at 15:36i wnat to have one slave i2c that receive data that transmit by master.
i wrote the master side, but in the receiver slave i dont know what should i do to get that data in i2c .
if anybody knows how should i do ,
you know, is think this procedure is true :''
The master is initially in master transmit mode by sending a
http://en.wikipedia.org/wiki/Start_bit
followed by the 7-bit address of the slave it wishes to communicate with, which is finally followed by a single bit representing whether it wishes to write(0) to or read(1) from the slave.
If the slave exists on the bus then it will respond with an
http://en.wikipedia.org/wiki/Acknowledgement_%28data_networks%29
bit (active low for acknowledged) for that address. The master then continues in either transmit or receive mode (according to the read/write bit it sent), and the slave continues in its complementary mode (receive or transmit, respectively).''
i don't know how to implement this in stm32f4.
at least i don't know in slave receiver side. please help me
