This demo is based on the GD32W515P-EVAL-V1.0 board, it shows how to use the I2C
interrupt programming mode in master receiving mode or slave transmitting mode.
In this demo, I2C0 is operated as the master receiver and I2C1 as the slave
transmitter. Moreover, the SCL line and SDA line of I2C0 interface are controlled
by the I/O pin PA15 and PB7 respectively. The SCL and SDA of I2C1 are controlled
by the pin PB15 and PA8 respectively.
This demo will send the data of i2c_buffer_transmitter array through I2C1 interface
to the I2C0, and it will store the data received by I2C0 in the i2c_buffer_receiver
array. If transfer is successfully completed, LED1 and LED2 are on.
We should use the jumper to connect the PA15 and PB15. The PB7 and PA8 are
connected as well.
