I'm using two boards for communication via I2C. I am using the following code to send the values in the TX_Data_Master[10] array to the second board. Below, I will add the code for the second board. In this code, the values from the TX_Data_Master[10] array will be saved to the RX_Data_Slave[10] array. When I send the codes to the boards and run the above code step by step, the program gets stuck at the "while(i2cIsStopDetected(i2cREG1) == 0);" part and doesn't progress. Additionally, the "i2cNotification()" interrupt does not trigger when the "i2cSend()" function is executed. WHAT SHOULD I DO? (I HAVE ALSO ATTACHED THE NECESSARY CODES FOR THE SECOND BOARD BELOW.) .
