Hi,

I have been working with the STM32L151RC uc and would like to read two of
it's internal ADC channels. The problem is RIOT present implementation por
the ADC only takes into account external ADC lines, witch means it require
a GPIO assignment. What would be the best way of implementing this? a new
function in the adc lib that doesn't need a GPIO assignment or implement
this a a CPU function since these internal ADC channels are used to get
internal voltage references and such. Best regards,

Francisco Molina
