stm32f07+touch

Question asked by roozitalab.alireza on Apr 9, 2015
hello every one
i want to connect touch panel to the adc of stm32f0 directly
so i use
 PA3->X+
PA4 ->Y+
PA5->X-
PA6->Y-
pa5,pa6 just use as gpio and pa3,pa4 use as gpio and adc both
i config the adc first and defult channel is channel_3
and during the code just changing channel and dont config adc or ... any more
if i read just chanel_3 the adc worked correctly and i have x value correctly but if i changing channel(to Channel) the values of channel_3 and channel_4 are wrongs


best regards
