/*! \file readme.txt \brief description of the slave transmitter */ /* Copyright (C) 2017 GigaDevice 2014-12-26, V1.0.0, platform GD32F1x0(x=3,5) 2016-01-15, V2.0.0, platform GD32F1x0(x=3,5,7,9) 2016-04-30, V3.0.0, firmware update for GD32F1x0(x=3,5,7,9) 2017-06-19, V3.1.0, firmware update for GD32F1x0(x=3,5,7,9) */ This demo is based on the GD32150R-EVAL/ GD32190R-EVAL board, it shows the I2C programming mode in slave transmitting mode.In this demo,BOARD_I2C is operated as slave transmitter,and the SCL line and SDA line of I2C0 interface are controled by the I/O pin PB10 and PB11(or PB6 and PB7) respectively. This demo shows the sending data process of the slave. And it will send the data in the i2c_transmitter array through the BOARD_I2C. The demo doesn't perform the data transfer actually, which is due to no specific master.In the specific application, we need config the master to start a data transmission.In addition,the master and the slave may need to be connected by the jumper if necessary.When the macro I2C_10BIT_ADDRESS is 1, I2C communicate in 10 bit addressing mode, otherwise, I2C communicate in 7 bit addressing mode.
