I encountered a data alignement problem when using the 3 ADCs.

ADC_Mode = ADC_TripleMode_RegSimult

ADC_DataAlign = ADC_DataAlign_Right had no effect. Data was allways left-aligned.

The Problem was that I omitted assigning a value to ''ADC_ExternalTrigConv'' as ADC_ExternalTrigConvEdge is set to ADC_ExternalTrigConvEdge_None.

->The solution was therefore to put:

''ADC_InitStructure.ADC_ExternalTrigConv = ADC_ExternalTrigConv_T1_CC1;''

The problem occurs in other ADC modes also. See my post STOne-32 ADC Lib Examples Problem on 24 January in this forum for more information and ST's response.
