Unfortunately, I’m of no help with the Touch Bar. My 13” MacBook Pro from 2018 is the version without. I never saw a reason for spending additional money at gimmicks like this.
Works as expected, congratulations!
Asks because downloaded from the internet which is ok:
Asks for permission to access the Documents folder which is ok:
Asks for allowing incoming network connexions which...
There is a Kinetis application note about the ADCs on the NXP website. These Delta-Sigma ADCs do NOT have a constant input impedance since each conversion cycle starts with loading an internal capacitor (low impedance,...
I fear that you'd have to try it out. Some DACs have an internal digital FIR filter which blocks DC. Even if not, you'd have to check out the useful (linear) DC range which can be obtained. IMNSHFO, a "normal" I2C or...
It's just that the limits for Vref are 1.25V to 3.3V (c.f. data sheet). Within these boundaries, the ADC is definitively ratiometric. That's why many users use the 3.3V Vdd reference when reading potentiometers whose...
All USB modes should be supported on the T4, soon. Paul told that he was working on this but that's not his only high priority, there are a lot of things still to do until the T4 will "turn round". So, please be patient...
Just a few thoughts:
1.) A theremin is characterized (see original US patents by inventor Leon Theremin himself) by sound generation through 2 directly heterodyning RF oscillators. From that point of view, the device...
A quick look into the source code of the I2S objects of the audio lib will tell you that one frame contains two 32bit words (one per channel). The audio lib does use 16bit audio which means that the least significant...
You can’t eat the cow and her butter, as we say in France. There are reasons why in high end audio devices, there are separate power supplies, separate grounds and separate shielded sections for the analog and digital...
Since PlatformIO uses its own build system, I’d rather open the issue with them. Be sure to add your full code base and the reported memory sizes after compiling with the old and with the new build system, so that Mr...
The Teensy 4.0 has already something like that integrated. The internal SAI3 can be combined with a so-called Medium Quality Audio Output which works based on PWM/PDM with internal oversampling and filtering.
The Teensy has 2 internal ADCs. A very sophisticated internal multiplexer allows to route several pins and signals to either the first ADC, or to the second, or (for some pins and signals) even both. And there comes the...
