Using STM32L452CC and STM32CubeProgrammer API v2.12.0 Windows 64-bits.Firstly, I'm setting the readout protection to its middle level (RDP = BB in the programmer) and then program the chip successfully. Then, letting the chip power cycle. Now reading...

Using the IWDG within STM32L452 in its window mode.At some point the application needs to freeze the IWDG module functionality, or as a minimum make it work as in non-window mode.Is this possible? If yes, using which function?Note the I couldn't loca...

I couldn't find within the data sheets whether the chip suffix, 3 or 6, which indicates temperature range, is programmed in the chip. This might help to set temperature alerts at the right level.Does it exist?

I'm using the below to calculate the temperature in STM32L452 CPU:int16_t temperatureC ;// ADC VREF is external 3V3temperature = __HAL_ADC_CALC_TEMPERATURE (3300, ADC_val, ADC_RESOLUTION_12B);For ADC_val = 1360 - then temperatureC is 164 Celsius, whi...

Thanks, Peter,Understood. In these days of chip shortage, R&D are asked to provide alternatives, so that various chips could be used inside the very same product.It would be a production nightmare to program each chip with different firmware.Somethin...

Thanks to all responders, every answer helped to locate the missing bit which was this:LL_ADC_SetCommonPathInternalCh(__LL_ADC_COMMON_INSTANCE(ADC1), ADC_CCR_TSEN | ADC_CCR_VREFEN | ADC_CCR_VBATEN );I still get 41C at room temperature, which seems hi...

Problem found: The macro __LL_ADC_CALC_DATA_TO_VOLTAGE was missing.
