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...
That workaround (right click the app, control+click "open") at the first launch does actually apply to almost all apps which aren't distributed through the Apple app store. It's the same with other popular non-app store...
Open the freshly downloaded Teensyduino.dmg with a double click:
It seems that it can't be installed. But it can. Click "OK". Make a right click on it:
Again, as before with Arduino, in the now open context menu...
OK, re-did everything. The struggle is twice in a similar way, once for Arduino, and once for Teensyduino.
After unpacking the downloaded Arduino.zip and moving the App into the Applications folder, you make a first...
I have it running here (Catalina and Arduino 1.8.10 and Teensyduino 1.48) . Install was some days ago. I remember that there was an additional hurdle, but I got over it. Don’t remember details, so will uninstall...
As if this hadn‘t been explained already more than 20 times in these forums... The short answer is no. The long answer is that a kind of programmer IC (the famous MKL02/04) is integrated on each Teensy board. The...
I guess that nobody tried it out up to now. Thus, it is like it‘s your turn to do so and report back here ;)
But be warned, the port might not be trivial since the audio stream object is not in the audio lib but in...
Running already macOS Catalina 15.1 beta here since last night. Fresh install of Arduino 1.8.10, granted rights, the installed Teensyduino 1.48 final release, not beta. Launches, loads sketches, compiles, and uploads...
You shouldn't make general conclusions from your individual problem. Fresh install of Arduino 1.8.10 followed by a Teensyduino 1.4.8 install gives a fully working environment under Catalina 10.15 (build 19A582a) on my...
Received my three 0.8mm breakouts yesterday. Unusable, went directly to trash. The small castellation for the bottom pads 24,26,...,32 simply missing, the big castellation totally misplaced. First time I have such a bad...
The built-in LED is on pin 13 which is a hardware capable PWM pin. So you can easily use the Teensyduino core features like analogWrite(), analogWriteResolution(), analogWriteFrequency() without having a library to...
Perhaps a silly thought from my side: The Teensy 4 has 4 flexpwm modules with 4 independent sub modules which have 3 independent channels, each. That makes already 48 hardware PWM channels. Then, there are 4 universal...
