Yes then finally use google. Do you seriously think I'll do it for you? Or anyone else? I don't care what ADC speed the Raspi has, and if it has an ADC at all.
LOL
Not with this chip :)
Have fun and...
1) The titel of this thread said "Oscilloscope".
2) You should explain what you want to do. The answer is in the datasheet of that sensor - whatever you want to do with it (you did not even explain that) Don't expect...
The absolute minimum for sampling a digital signal at 1MHz is 2MHz. Better is 10 or 100 times the rate - depending on the need, (and whether the signal is analog or not).
The Teensy 4.x CPU supports a maximum of...
When it comes to this, and really fast signals, the layout on the board also plays a role. But i'm sure the lcd is well below 100MHz, more likely 30..60MHz max.
Just try to keep the layout of faster signals...
Almost. It is a bit more flexible - 150MHz maximum, and is calculated and set in clockspeed.c.
(I played a bit with overclocking the IPG, but in the end it wasn't really stable, and you should refrain from doing so)
...
Hard to say, since half of it is missing, nobody can try it out and compile it.
Just two general hints: "Register" has been obsolete for decades and is generally not used anymore. Simply because today's compilers...
You already had this information:)
As I wrote in my first answer: Yes, IRQ_SOFTWARE is used by the audio libary.
My (mp3,acc etc) Audio-codecs library uses IRQ_Reserved1 in additon.
It can be any of the interrupts. USB for example also uses interrupts.
You just shouldn't do it in software.
If you really want to do it in software without glitches, you have to disable all interrupts. You will...
The eventresponder is evil. It disables the interrupts (unnecessarily) and makes the timing of the system more unpredictable. Even if you don't use it at all.
Yes, that is the intention of these functions.... however you can't really rely on AudioProcessorUsage() because there are some things that are not taken into account.
But for a rough estimation it is good enough (in...
You can use any.
All are can be used as software interrupt, too. Just make sure they are not used otherwise.
There are some unused.. IRQ_SOFTWARE is used by the audio library (yeah I don't like this name, as it says...
I guess, yes. But I don't think PJRC is going to make this.
They have other small boards like the PT8211 for audio and their SD shield.
If you want to play MP3 only, from the SD only, yes. I doubt you can...
I would simply use Platformio. A ready to use application.
Some buttons (e.g. clean, compile, serial monitor, upload) are at the bottom of the window.
Platformio has a really powerful editor, GIT integration without...
Try warm water and isopropyl. It must be clean.
Don't bee too harsh with the toothbrush. It could easily tear off small SMDs.
Be sure that it is really dry before re-connecting it. Even under the chips, where you do...
Yup, this is due to the way the crash report is implemented. You can see now (again) which option does not work ;)
A fix for the report would need a bit of effort, but is easy.
...and you already have this situation.
There are many problems here in the forum because the oh so fast 4.x is waiting for something. Then you wonder what all the MHz are actually good for, and certain things in the...
In the ESP world, this is usually not a big problem. The libaries take this into account, and have been adapted in the past.
But of course, if you never start, or can't start because there is no PJRC supported RTOS,...
The question remains: Why that teensy addon (which officially never will have multithreading "out of the box" ) to an ESP? There are only some corner cases where a faster CPU without own WiFi is really needed (as...
I just skimmed this thread, but I don't think anyone felt the need to explain things to him.
Tjaekel, I think you just have a basic misunderstanding:
The CPU allows a flexible configuration, i.e. division of...
