Hi Guys,
Want to ask for a quick bit of advice please.
I have a STM32F407 running on a board that has been configured to count frequency (number of pulses per second - period and duty cycle are va...

OK this is weird...
I have access to the same frequency input signal via both pin PD2 and PE0. PD2 can route to timer 3 ETR and PE0 can route to timer 4 ETR.
I set up timer 3 as below:
GPIO...
Posted on June 10, 2016 at 13:44Got a frequency simulator and plugged it in for testing. Using external interrupt counting I simulated a 9600Hz signal and measured exactly 9600Hz as the output from software. Using a very, very old frequency counter ...

I will look into getting a source for a fixed frequency input as then I will know which version of the code is ''correct''.
Currently I am using the same frequency input source (minor variations are possi...
