Hello,
I' using CCS C example of code for UART communication between one Master and one Slave. It's work well.
However, i'm trying now with two Slaves, One Master and i have problem. 2 slave data transmission on the master was wrong
I do not know how to address the slave, Who has successfully share information
code master
Slave 1:
slave 2:
