The output stream should have higher priority than the input stream. (#) Configure the ADC Prescaler, conversion resolution and data alignment using the HAL_ADC_Init() function. (#) Configure the ADC Injected channels group features, use HAL_ADC_Init() and HAL_ADC_ConfigChannel() functions. (#) Three operation modes are available within this driver : *** Polling mode IO operation *** ================================= [..] (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart() (+) Wait for end of conversion using HAL_ADC_PollForConversion(), at this stage user can specify the value of timeout according to his end application (+) To read the ADC converted values, use the HAL_ADCEx_InjectedGetValue() function. (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop() *** Interrupt mode IO operation *** =================================== [..] (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart_IT() (+) Use HAL_ADC_IRQHandler() called under ADC_IRQHandler() Interrupt subroutine (+) At ADC end of conversion HAL_ADCEx_InjectedConvCpltCallback() function is executed and user can add his own code by customization of function pointer HAL_ADCEx_InjectedConvCpltCallback (+) In case of ADC Error, HAL_ADCEx_InjectedErrorCallback() function is executed and user can add his own code by customization of function pointer HAL_ADCEx_InjectedErrorCallback (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop_IT() *** DMA mode IO operation *** ============================== [..] (+) Start the ADC peripheral using HAL_ADCEx_InjectedStart_DMA(), at this stage the user specify the length of data to be transferred at each end of conversion (+) At The end of data transfer ba HAL_ADCEx_InjectedConvCpltCallback() function is executed and user can add his own code by customization of function pointer HAL_ADCEx_InjectedConvCpltCallback (+) In case of transfer Error, HAL_ADCEx_InjectedErrorCallback() function is executed and user can add his own code by customization of function pointer HAL_ADCEx_InjectedErrorCallback (+) Stop the ADC peripheral using HAL_ADCEx_InjectedStop_DMA() *** Multi mode ADCs Regular channels configuration *** ====================================================== [..] (+) Select the Multi mode ADC regular channels features (dual or triple mode) and configure the DMA mode using HAL_ADCEx_MultiModeConfigChannel() functions. (+) Start the ADC peripheral using HAL_ADCEx_MultiModeStart_DMA(), at this stage the user specify the length of data to be transferred at each end of conversion (+) Read the ADCs converted values using the HAL_ADCEx_MultiModeGetValue() function. @endverbatim ****************************************************************************** * @attention * * <h2><center>© COPYRIGHT(c) 2014 STMicroelectronics</center></h2> * * Redistribution and use in source and binary forms, with or without modification, * are permitted provided that the following conditions are met: * 1.
