ahh okay sorry Teensy 3.x doesn't use setClock, 4.x only.
you need to put that msg.flags.extended with your message you wanna send. put it under your msg.id = 0x108180fe;
msg.flags.extended = 1;
this must be set BEFORE writing, or else your extended ID will truncate to a standard ID and it will not be the one you wanted for your device
also try adding in setup:

Hello Guys,
I have a problem with my current project reproducing the IMU Headtracker vom Gregory Pauls Hackaday Site (https://hackaday.io/project/8952/instructions)
Problem is, the MiniIMU board from Pololu...
it looks like you are flooding the bus with writes, are you sure the device can process the data that fast? usually on cars we need to space the transmissions to a device at like 10ms, but your loop is constantly...
Hi,
please, tell me, what am I doing wrong?
when the temperature of the external device rises, the power supply R4850 must reduce the output voltage,
the code works, but when switching the voltage there is a delay of...
Thanks Frank! Wish I had seen this thread earlier :) Last week, I was experiencing similar issues inside a loop that "normally" took around 22ms for ~500 iterations, experiencing "freezes" every 50 or 60th iteration for...
1) You may need a particular connector for the sensor. Check the sensor data sheet.
2) The Teensy 4.1 has 8 hardware serial ports.
3) You will probably need to build your own filter. So far, you have not provided...
would rather use this with millis.
I’ll stick with that, I have a few function calls with SPI, currentsense encoder and TFTScreen in the background.
I think this is a better start. For the INA pin. I’ll leave INB...
Thanks for checking - have to retest.

Yep - VID only works in DMA mode as it did before but 'F' and 'f' works with FlexIO as before.

I guess I have another problem now, the esc shuts down sometimes at full throttle. I've been doing some research and while it could be several other things, one person had the issue and solved it this way;

Yep 'f' - single shot, 'F'-continuous (still not working if in DMA_8BIT mode but it does give you what you describe - what about 'V' ideo ? That's the one I am curious about.

Thanks would appreciate - all else seems to be working with DMA though. Already created WIP branch on github: https://github.com/mjs513/TMM-HB01B0...ree/API-Rework

Just a quick update. Been trying to figure it out most of the day. Found a couple errors but still no luck with video mode. So I bypassed my readframe's etc and used direct calls but no luck. Not sure if its...
Thanks for the reply.
I still do not understand, the pin configuration of a ICS52000 is shown in the figure
which shows SD, WS, SCK, not the MCLK, BLCK, LRCLK.

now its my turn, i didnt understand a thing you just told me, no offense.
never worked with ISR, had it in my studies but never worked with it.
no clue what speeling is.

Keep in mind this code was originally written in 2014 for Teensy 3.0 and 3.1. When talking of how to "achieve acceptable performance", remember it is also meant for a those older boards which don't have a FPU.

I'll give a few basic answers and maybe one of the experts can fill in the details.
This code uses a wavetable (AudioWaveformSine). Is this absolutely necessary to achieve acceptable performance on...
It can help to write out a statement of expected behavior in text. Without that even looking into the behavior of 'close' code won't help because what is wrong won't be obvious not knowing what it should be doing ......
Thank you. I tried this but every time I recorded samples, The number of samples is different. Is there a way I can get a constant number of samples for a specific time duration like 10 seconds?
CLK and DATA are normal names for encoder signals. If you read DATA on the rising edge of CLK, it tells you whether you turned one detent left or right. CLK and DATA match up exactly with a flip-flop, or other digital...
Are you using an encoder with detents?
The detents are often set at a particular point in the quadrature cycle, so if you disable interrupts and happen to only poll read() when the encoder is at detents, the state...

Forgot about the table you have in the FlexIO library - was actually looking to create one - sort of.
Right now the way it looks is the DMA is used for both for DMA mode and FlexIO mode (works better). The...
I tried this code. This is really good. I have a question if anyone would like to answer; Could I go to StopLogging(void) using pre-defined time instead of using q or p?

You probably need to show your full code. There is no explanation of "nexSerial".

Now for instance. For DMA I see that the function:

i thought combining the two independent millis into one would be proof much usefuller, why is it only reacting to the first If statement in the void loop?
why cant i control the OnTimePulseClock and OffTimePulseClock?...
As far as I can understand MPE uses standard MIDI transport, but assigns a dedicated channel to every playing note. So USB MIDI should work, but user code has to adapt.
Hi, I am trying to read SBUS with Teensy 4.0, the code has been working fine on teensy 3.2. There could be something else wrong also, but should Teensy 4.0 support Serial3.begin(100000, SERIAL_8E1_RXINV_TXINV); ?

Yes, always best to avoid delay() unless it is short and time critical as that stops other normal loop() code.
Seems like that gives the needed tools now to work it out.
It could be done other ways as well,...

ok thanks. that seams pretty conclusively that it is a thing with the library. maybe there is a keep alive message that it is not sending that i need to look into.

I am having the same issue with sleep disconnecting the USB-MIDI and also have a device (Arduino Leonardo) that does not have this issue. id you ever find a fix?
Exactly the same issue here. I'm trying to use with Teensy 4.1.
I believe from another thread that the TLC5940 uses MCU specific code for speed.
Fingers crossed Teensy 4.x is added!
