Laurent MEUNIER 9895bcf130 STM32 I2C: restore slave address in case of reset 2016-12-12 14:44:37 +01:00
Laurent MEUNIER 29b32b84b3 STM32 I2C - 1MHZ frequency is allowed 
So make the assert to cover all possible values
Also assert applies only for I2C_IP_VERSION_V2.
Also in case of I2C_IP_VERSION_V1, the HAL makes the proper
checks and can dynamically scale the frequency in case of
intermediate value.

Laurent MEUNIER 3fad50287c [STM32] Make most of the I2C code into a common file 
Since most of the code in i2c_api.c is now relying on STM32 HAL, there
is now a possibility to make a common usage of this code accross families.

The IP version definition is introduced per family, to allow a switch of
functionnalities, especially the frequency management which differs.
BTw, we fix the F0 frequency settings at the same time.

F1 is managed for now as an exception as the HAL API for sequential transmit
/receive is not yet available (coming soon)
