Re: Is stm32f4 the right chip?

It was also my conclusion at work but the part where you need to tune everything ups takes much more time than what was first planned that I was wondering how much time could have been saved by taking a different avenue... I am still getting over the code for the next months... But my real conversio...

Re: Is stm32f4 the right chip?

Hi, I am looking at some recent post and two issues seems to prevail: i/o and timing. (The two are also a big constraint at work, and i'm actually doing the thinking for both here) Any microcontroller is going to have issue when trying to have absolute timing using interrupt or a really big number o...

Re: analog inputs: op-amp + divider - Russian - LMV324IDT

You could also use an opamp connected to a higher voltage. This would also help with accepting analog signals up to 12V without being clamped in the op amp inputs... I don't recall having seen 12v analog signal, but i did not get in the details of a lot of sensor ( wideband O2 for example). I know o...
