How should I configure the ADC on my STM32F407VG to properly acquire data from an LM35?
hey guys, I'm initializing the ADC peripheral to read data from the temperature sensor while referencing the STM32F4 reference manual , how should I configure the ADC on my STM32F407VG to properly acquire data from an LM35 temperature sensor? Are there any recommended libraries or code examples available for ADC initialization on the STM32F407VG? the factors to consider include the resolution and sampling rate required for accurate temperature readings. @Middleware & OS

Well, @Dtynin in order to configure the ADC on your STM32F407VG to acquire data from an LM35 temperature sensor, you need to set the ADC resolution to 12 bits for accurate readings and choose an appropriate sampling time.
I believe 15 cycles is more than enough to ensure balance between speed and precision

@Sterling I'll set the ADC resolution to 12 bits and configure the sampling time to 15 cycles for a good balance of speed and accuracy.
I appreciate the tutorial links. I'll review them to better understand ADC initialization on the STM32F407VG. These should give me the libraries and code examples I need.
If I run into any issues or need more help, I'll reach out again. Thanks for the support!
You welcome @Dtynin
