Joe, sorry for the delay, I didn't have access to my Teensy and computer during the weekend. I was not able to reproduce the error mentioned by you when we check for stack corruption. I tried to comment out many...
Arduino/Teensy code is compiled using a GCC C++ compiler, so you can just consult the C++ documentation: https://en.cppreference.com/w/cpp/header/cmath#Functions
Dear Paul,
thank you for your answer, I was on a busniess trip and no way to test it. I did the reset and worked again, now I see the arduino code is ok, as it is working with CAN analyzer, so I need to figure out...
I've made the buffer size configurable at run-time, per object. The code reads half of the buffer at a time, when there's space available, and I'd strongly recommend making the buffer a multiple of 1024 bytes, so a half...
Update,
I have used a Teensy 3.6 at various speeds and overclocks.
Freezes at PDB0_MOD = 1023
When run at overclock, the PDB0_MOD starts at higher values and freezes at the same 1023.
OK, if I can get 10-20 24 kHz voices directly of an SD card, then I won't use spi flash at all.
What blocksize do you read from the SD card? How much buffering is needed? It would be nice if I could run it out of the...
I’m currently working on streaming off the T4.1 SD card, using internal heap or PSRAM as a buffer. So far I’m comfortably achieving 16 channels at 16-bit 44kHz from standard mono WAV files, off pretty much any card I...
Hi,
I'd like to know where the math functions are documented.
I found a list here: https://www.arduino.cc/reference/en/
But this list is incomplete. For example atan(), atan2(), log(), asin(), acos() are missing in...
I'd like to use a T4.1 with a 32/64/128 mbyte spi flash for polyphonic audio playback (10+ streams possible?)
The streams are mono 16-bit 24kHz (or similar mid-quality). Processing will probably be limited to gain...
Hello,
I am using a Teensy 4.0 from SKPANG with LIN and CAN support. I would like to simulate a LIN slave that can read headers from the master and respond back. Would this library support something like this, and if...
The screen clearing is an artifact of the SerMon tool in use.
TyCommander does not do that (except on upload if chosen) - though it does drop the Teensy after some 10 seconds of it going offline. But it caches all...
Here is the code, though it is pretty much the stock example code minus some misc stuff that wasn't being used in my particular application. I started to pull stuff out after running into the issue to try to make the...
I should mention a simpler approach is to use something like the dfplayer that has a SD card and can emit audio directly. There you only send it commands from the Teensy, and you don't have to have two things that both...
I had done it in the days when I was using the Teensy 3.2/3.5/3.6 on the 128x128 TFT displays (in 2018) with the prop shield using the built-in DAC for the sound and encoding the sounds as RAW files built-into the...
The problem is a different one.
The code I posted was an extract from a large code. I missed to copy some lines with watchdog statements. Sorry for that.

If you just wanted the value as a sequence of bits, the C/C++ method is to do shifting and masking. There are two ways to number the bits. The first method is big endian where bit #0 is the sign bit, and in a 32-bit...

@Rezo - looks good.
My guess is that if you were not trying to write it to two places, you would not need the Stream stuff, but simply print the CrashReport to the SD file.

I'm not sure I understand you correctly since an integer is stored binary into memory.
But perhaps you mean that you want to store "10000000001000" as a character string?
You can use the itoa function.

Hi All,
I'm looking for a simple way to convert an integer to a binary number and store it in 1's and 0's. The code below does exactly what I need... it converts 8200 to 10000000001000, but doesn't store it. How can...
If I read the datasheets correctly, both the TLV75733P and NCV8186 are short-circuit protected and therefor unlikely to fail.
If you don't see a short from 3V3 to GND, you could power the Teensy from 3V3 only and see...

Thank you very much @defragster for responding.
So in the code above, feedTheDog() is called by the loop every 5500 ms. If 30 seconds go by and the automated interrupt callback had not been called, the Teensy will...
Two numbers control the function.
That third 5500 is just to limit the repeat calls to wdt.feed() to no more often than 5.5 seconds

Yes, it just allows indexing each byte of the 2 byte number. So code should just suppl it with the desired 16 bit value and it deals with the transfer.
Thanks for the reply.
I tried commenting out the private; line so everything was public. I still get the same error. The _pin variable is private and doesn't cause any errors.

I'm trying to port my application from a teensy 3.2 to teensy 4.0. I used the built-in DAC in the 3.2 so I will need to use an external one with the 4.0. I found a library for the MAX5443 in an old github project. It...

Thanks for the clarification. I mistook it for being involved with the voltage regulation.
Done, no short.

I've played briefly with S/PDIF on a Teensy 4.1. I received audio generated by a Teensy 3.2, connected electrically (3.2 pin 22 to 4.1 pin 15); and output from pin 14, via a TOSLINK transmitter, to a cheap S/PDIF to...
Thanks a ton for the quick reply and confirmation. That makes a lot of sense.
I actually am planning on using 1/8" TRS plugs/sockets. Any idea what should be added where to the circuit to protect it better?
The possible problem I can foresee is that LoRa is very low level transmission data and I will have multiple sensors sending data to a GUI and App on Android. Can anyone give me any information on this aspect.

I merged in your PR.
Have not looked at the LEDs yet. But I would probably look in wacom_sys.c for references to the word INTUOS5.
Like in wacom_initialize_leds()
And then look at functions like...
Probably you have seen this thread?
This board does SPDIF output for Teensy 4.1 as well.
According to the Audio System Design Tool, Teensy 4.x outputs on pin 7 instead of pin 22 for Teensy 3.x.

Nope, the third pin is the gate of the FET connected to GND. See schematic.
You may want to check whether the output of U4 TLV75733P voltage regulator] is shorted to GND somehow.
