I believe on of the main system clocks maxes at 150MHz (w/o overclocking), so multiples of that are used (the large datasheet has details of all the PLLs and clock domain/trees and if you have the patience that may...

Forum rule? We can't help without seeing what you did...

One way is to take pull request from the Teensy audio library repo and add your object - if its worth having it might be considered for incorporation.

You are measuring the performance of the oscilloscope's front end I suspect - scopes like that one are 8 bit - some can be configured for ~11 bits effective, but the front end analog stage is not very linear anyway (it...

Timbre varies with frequency even for identical harmonic profiles I fear. Human hearing is very adapt at perceiving the filter envelope separate from the excitation note(s) as this is the basis of vowel recognition...

Hi. These are typically Hall sensor (actually Hall switch) outputs used for commutating a BLDC. Some have 120 degree spacing, some have 60 degree spacing, so you'd need to have the option of configuring for either...

The way to sort this problem out is a forensic investigation of failed boards to see what's actually happening with the solder balls. There could be many potential causes I fear, such as not being able to handle...

One of the issues of using a logic analyzer is they give no information on signal integrity, whereas a reasonably capable 'scope with x10 probe may instantly diagnose issues like this. Perhaps crosstalk, ground-bounce,...

That really is a thing... Batteries have internal resistance (which changes with state of charge, temperature, battery age) - but often it is in the range of milliohms, so you can often ignore it, but you'll see it in...

Table lookup is one approach, combine the inputs into a single int and do the lookup, then expand for the outputs - the advantage is each logic function just needs a different table, not more coding, the disavantage is...

In CMOS chips pullups and pulldowns are implemented as weedy little MOSFETs with a long narrow channel, giving resistances in the 10's of kohm range (and I repeat nothing to do with drive strength at all). Drive...

Microcontrollers are much less complex that computer CPU's, they benchmark much more consistently - being tied to hardware (hard real-time constraints) means adaptive clock speed is more problem-shaped than...

In general its wise to only turn interrupts off for timescales of microseconds, typically as a "critical section" (small amount of code bracketed by cli/sei). You never just turn them off and leave them off as many...
