* Name: stm32_adc_initialize
|

*
|
||||
* Description:
|
||||
* Initialize the ADC.
|
||||
*
|
||||
* The logic is, save nchannels : # of channels (conversions) in ADC_SQR1_L
|
||||
* Then, take the chanlist array and store it in the SQR Regs,
|
||||
* chanlist[0] -> ADC_SQR3_SQ1
|
||||
* chanlist[1] -> ADC_SQR3_SQ2
|
||||
* ...
|
||||
* chanlist[15]-> ADC_SQR1_SQ16
|
||||
*
|
||||
* up to
|
||||
* chanlist[nchannels]
|
||||
*
|
||||
* Input Parameters:
|
||||
* intf - Could be {1,2,3} for ADC1, ADC2, or ADC3
|
||||
* chanlist - The list of channels
|
||||
* cchannels - Number of channels
|
||||
*
|
||||
* Returned Value:
|
||||
* Valid ADC device structure reference on success; a NULL on failure
