Dear All,
Do you find any VSSA (VRef-) pinout on the STM32L432 32QFN ?
The Analog Input never stable !!
when PA_1 NC, PA_0 result:
0V = 7FFH
3.3v = FFFH
when PA_1 to GND, PA_0 result:
0V = 0H
3.3v = FFFH
when PA_1 to 3.3V, PA_0 become floating....
I can not find Vref-, and also guess the Vres- no connect to GND internal.
Any solution ?
Thanks,
