The communication is a configured on 7bit addressing mode with a clock speed set to 200KHz. After enabling the two I2C peripherals and the two event and buffer interrupts, the transfer in 7-bit addressing mode starts after the I2C1 start condition is generated. Each time an event occurs on the master or the slave, it is managed in the I2C1 or I2C2 interrupt routine, respectively. In this application, I2C1 Tx_Buffer is transmitted from the master (I2C1) to the slave (I2C2) and stored into I2C2 Rx_Buffer. At the end of the transfer, the PEC is transmitted from master to slave. It is then saved in the PEC_Value variable. All transmitted and received buffers are compared to check that all data have been correctly transferred.
