Hey everyone. I am using a STM32F4 - Discovery board to read an analog value from a pressure sensor to convert it into depth. My problem is that the sensor that I need works with 0-5V and my STM32F4 works only with 3.3V. Is there any way to make the analog read module's reference an external 5V that I provide?

Hello,
You are facing an issue that is more related to the discovery kit capabilities. If possible, I recommend you to post your question to the microcontroller forum. And especially in the STM32 evaluation tools category. Here is a shortlink :https://my.st.com/public/STe2ecommunities/mcu/Lists/STM32Discovery
If you need op-amps or comparators in your designs, in addition to STM32 you can also think to the wide ST analog portfolio. Thanks and regards, Sylvain2014-04-07 01:51 AM
