I2C_Select_Speed
Void I2C_Select_Speed (I2C_Speed_Param
Speed_Value, unsigned int I2C_Speed)
Selects the I2C clock speed both in standard and fast
speed modes.
I2C_DEFAULT_PARAM2
Sets standard speed mode
I2C_FASTSPEED
Sets fast speed mode
I2C_Speed
You can select any value from 0 to 400.
Standard speed mode range: 0 to 100 kHz
Fast speed mode range: 101 to 400 kHz

1. I2C_Init must have been called.
2. Fcpu must be defined in ST7lib_config.h.
3. For multimaster I2C configuration the
I2C_MultiMaster_Config function must have been called.
4. If you enter speed ranges from 101 to 400 kHz, the pa-
rameter ‘I2C_FASTSPEED’ must be selected in input pa-
