  32. This demo is based on the GD32307C-EVAL-V1.1 board, it shows the I2C programming
  33. mode in master receiving mode which the master only want to receive one byte of
  34. data. In this demo,I2C0 is operated as master receiver,and the SCL line and SDA
  35. line of I2C0 interface are controled by the I/O pin PB6 and PB7 respectively.
  36. This demo shows the receiving one byte process of the master. And it will store
  37. the received data in the i2c_receiver array.
  38. This demo doesn't perform the data transfer actually, which is due to no
  39. specific slave.In the specific application, we must send the correct slave
  40. address, and the master and the slave may need to be connected by the jumper
  41. if necessary.
