Hi,We have a custom firmware running in an STM32F427, and I'd like to find out what the highest frequency supported on a timer with an external clock source using ETR function.Based on AN4776, I can use a prescaler function (ETR) to read clock freque...

We have several units of LSM6DSL in the field and I was looking that this part has an embedded temperature sensor. I would like to understand better the accuracy of this sensor. The datasheet is not clear, showing only this information. Can I assume ...

Hello, AScha.3.This was my first understanding of the ETR function, but given the limits mentioned on the datasheet and the lack of additional information, I was uncomfortable advancing with experiments without a third opinion from you experts. My fi...

Hi AScha.3,That's where I got confused because the AN4776 gives an example based on what I passed. This causes the IO to exceed the specified limits. See the example:Even if I take the datasheet indication of 1/4 of CK_INT into account, the value rea...
