Hello,
I have a problem with internal reference in STM8L151K6. I run Vrefint channel measurement. I read VREFINT_Factory_CONV from @ 0x4910.
Measurement values:
Vref_measured: 1311
VREF_Factory: 0x600 + 0x7B = 1659
VDD_Factory: 3V -+ 10mV
Why Vdd = ( VREF_Factory/Vref_measured ) * VDD_Factory is 3796 mV ? My real Vdd on board is 3300mV !
What did I do wrong ?

What was your ADC sampling time during VREFINT conversion ?
