##### FMPI2C peripheral Extended features #####
|
||
|
|
==============================================================================
|
||
|
|
|
||
|
|
[..] Comparing to other previous devices, the FMPI2C interface for STM32F4xx
|
||
|
|
devices contains the following additional features
|
||
|
|
|
||
|
|
(+) Possibility to disable or enable Analog Noise Filter
|
||
|
|
(+) Use of a configured Digital Noise Filter
|
||
|
|
(+) Disable or enable Fast Mode Plus
|
||
|
|
|
||
|
|
##### How to use this driver #####
|
||
|
|
==============================================================================
|
||
|
|
[..] This driver provides functions to:
|
||
|
|
(#) Configure FMPI2C Analog noise filter using the function HAL_FMPI2CEx_ConfigAnalogFilter()
|
||
|
|
(#) Configure FMPI2C Digital noise filter using the function HAL_FMPI2CEx_ConfigDigitalFilter()
|
||
|
|
(#) Configure the enable or disable of fast mode plus driving capability using the functions :
|
||
|
|
(++) HAL_FMPI2CEx_EnableFastModePlus()
|
||
|
|
(++) HAL_FMPI2CEx_DisableFastModePlus()
