Tool/software:
Hi Team
I Have configure I2C3 in slave mode with receiving interrupt using AM263x LP kit. But i am not able to call my callback function. can you please check once and let me know still what i am missing.
also can you please guide me how i can configure I2C in slave mode with receiving interrupt.
Another Point I have configure two I2C in this kit for just reduce hw connection. but I am able to put and get data in both resistor I2C_ICDXR & I2C_ICDRR resistor but its not storing in the variable can you please let me know why its happing.
please collect attached main.c file and syscfg file. and some uart log also.
