// The trace device is an independent output channel, intended for debug
|

// purposes.
|

//
|
|

// The API is simple, and mimics the standard output calls:
|
|
||||||
// - trace_printf()
|
|
||||||
// - trace_puts()
|
|
||||||
// - trace_putchar();
|
|
||||||
//
|
|
||||||
// The implementation is done in
|
|
||||||
// - trace_write()
|
|
||||||
//
|
|
||||||
// Trace support is enabled by adding the TRACE definition.
|
|
||||||
// By default the trace messages are forwarded to the ITM output,
|
|
||||||
// but can be rerouted via any device or completely suppressed by
|
|
||||||
// changing the definitions required in system/src/diag/trace_impl.c
|
|
||||||
// (currently OS_USE_TRACE_ITM, OS_USE_TRACE_SEMIHOSTING_DEBUG/_STDOUT).
|
|
||||||
//
|
|
||||||
// When TRACE is not defined, all functions are inlined to empty bodies.
|

##### I2C peripheral Extended features #####
|
|
||||||
==============================================================================
|
|
||||||
|
|
||||||
[..] Comparing to other previous devices, the I2C interface for STM32F0xx
|
|
||||||
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(s)
|
|
||||||
(+) Disable or enable Fast Mode Plus
|
|
||||||
|
|
||||||
##### How to use this driver #####
|
|
||||||
==============================================================================
|
|
||||||
[..] This driver provides functions to configure Noise Filter and Wake Up Feature
|
|
||||||
(#) Configure I2C Analog noise filter using the function HAL_I2CEx_ConfigAnalogFilter()
|
|
||||||
(#) Configure I2C Digital noise filter using the function HAL_I2CEx_ConfigDigitalFilter()
|
|
||||||
(#) Configure the enable or disable of I2C Wake Up Mode using the functions :
|
|
||||||
(++) HAL_I2CEx_EnableWakeUp()
|
|
||||||
(++) HAL_I2CEx_DisableWakeUp()
|
|
||||||
(#) Configure the enable or disable of fast mode plus driving capability using the functions :
|
|
||||||
(++) HAL_I2CEx_EnableFastModePlus()
|
|
||||||
(++) HAL_I2CEx_DisableFastModePlus()
