Hi
Can we use internal regulator for ref voltage of ADC of STM32L152? if you have experienced it please tel me how to do?
Thanks for reply. I read by this command:
battery_val=ADC_Supply();
which calls
ADC_GetConversionValue(ADC1);
I have not connected VREF+ to any power source in my board is there a way to connect it internally to vref of MCU by software?
Which part exactly are you using? Some devices have +VREF internally bonded to VDDA, and -VREF internally bonded to VSSA. On devices with VREF pins *you* have to connect them to the supplies yourself, in your design. I'm reasonably sure there is not a magic software setting, but try reading the manuals.
Isn't VREFINT on CHANNEL 17?
