This demo is based on the GD32W515P-EVAL-V1.0 board, it shows the I2C programming mode in master
transmitter mode and slave receiving mode. In this demo, I2C0 is operated as master transmitter
,I2C1 is operated as slave receiver and the SCL line and SDA line of I2C interface are controlled
by the I/O pin PA15 and PB7(or PB15 and PA8) respectively.
This demo shows the sending data process of the master and the receiving data process of the slave.
If transfer is successfully completed, LED1 and LED3 is light.
We should use the jumper to connect the PA15 and PB15. The PB7 and PA8 are connected as well.
