* @brief FMPI2C Extended HAL module driver. | |
* This file provides firmware functions to manage the following | |
* functionalities of FMPI2C Extended peripheral: | |
* + Extended features functions | |
* | |
@verbatim | |
============================================================================== | |
##### 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 wakeup from Stop mode | |
##### How to use this driver ##### | |
============================================================================== | |
[..] This driver provides functions to configure Noise Filter and Wake Up Feature | |
(#) 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 FMPI2C Wake Up Mode using the functions : | |
(++) HAL_FMPI2CEx_EnableWakeUp() | |
(++) HAL_FMPI2CEx_DisableWakeUp() | |
(#) Configure the enable or disable of fast mode plus driving capability using the functions : | |
(++) HAL_FMPI2CEx_EnableFastModePlus() | |
(++) HAL_FMPI2CEx_DisbleFastModePlus() | |
