Question
Hard fault when accessing STM32L0 calibration values
Posted on January 27, 2017 at 11:39
Hi,
When accessing some calibration registers, I get a hard fault. It might be due to unaligned access.
Is the '
stm32l0xx_ll_adc.h,
V1.7.0' correct?The 'VREFINT_CAL_ADDR' works correctly.
'TEMPSENSOR_CAL1_ADDR' and 'TEMPSENSOR_CAL2_ADDR' do not...
/* ADC internal channels related definitions */
/* Internal voltage reference VrefInt */
