@KurtE and @lokki

Found that I had the same issue with my CTH-480 tablet. Think I may have resolved it for both our tablets. I pushed up the changes for touch to the repository so if you want to...

What about touch. The 64 byte message contains the touch data, from your previous post which the update did I believe

and after hacking the digitizer sketch

begin, usage=D0000
type= 2
min= 0
max= 1
reportcount=6
usage count=4
Input, total bits=6
usage = D0042 data = 0

Yep. Hacked up the wacom lib a bit and did manage to get one packet before it stop:

HPID(16): 0A C0 FF 7F 99 49 00 00 00 00 00 00 00 00 00 00
begin, usage=D0000
type= 2
min= 0

I decided to attach a Teensy 3.6 and rerun the DeviceInfo sketch. This time it looks like it picked up both devices but with errors on the tablet:



USB HID Device Info Program

This Sketch...

If I attach the tablet to a RPI4 and run LSUSB -V it does pick it up.

While playing with the new WACOM Library (https://forum.pjrc.com/threads/70824-USB-host-Teensy-4-1-with-Wacom-Intuos5/page2) I plugged in a HUION Inspiroy H640P Graphics Drawing Tablet and ran...

@KurtE
Just gave your updated sketch a try and without turning off debug or changed data"

$HIB:ff0d0000 type:2 min:0 max:255
Digitizer: &usage=100(in:FF000100), usage_page=ff00, value=0(0)...

At @KurtE's suggestion I changed line 234 or so to <10 so it should look like this

void Intuos5Controller::hid_input_end() {
if (debugPrint_) Serial.printf("$HIE\n");
if...

Some of the answers may be found in the original thread started by @ftrias: https://forum.pjrc.com/threads/41504-Teensy-3-x-multithreading-library-first-release. Going through it I did find where he...

Just uploaded your code snippet to the Teensy3.5 and yes I got the same results as you did using "printf" however if you change it to just "print" it works, i.e., continuously prints "Threads...

You sure the problem is not a short on the wires to the oled - not sure how you are powering the OLED. I would start there and do a double check. That is about the only thing I can think of at this...

You can do that but don't put that code snippet in your sketch. The prints are already in the digitizer class so once you turn debug on you are good to go.

Not stupid question - I sometimes forget to explain fully. Unfortunately you can not turn debug on from the sketch. You have to edit USBHost_t36.h which is located in:
...

Might help if you showed how you are connecting the propshield to the LC. Are you sure you are not putting power to ground or something like that. You can get answers if you give us some more...

You might want to turn debug on for testing purposes for the Intuos5 there might be different usage pages involved than the ones with identified in digitizer.cpp. For instance if its turned on:

Just finished downloading RC9.1 and had to give the Compiling progress bar a test. Really liked that they added that feature - makes it easier to see whats going on.

Release of IDE2 has to be...

Just did a quick read through and just a couple of simple comments.

Morning Paul

Just finished updating RPI4 with IDE 2.0 RC9 and installing 1.57. Install went well and was able to upload a simple sketch to the new unlocked T4 with no problem.

Good morning all

IDE2 install went without a problem on the Windows 10 pc. Did see this on the install of IDE2:

Only can answer the SREG issue. I ran into that on another project and it is not supported on the T4.x's. You might want to check this thread...

Morning all.

Just did a install on a Windows10 pc x64. Install for IDE2 went well no issues - just took a while for it to update the boards. Shows as 1.57.0-beta4 in the dropdown. Running RC9...

If you mean just compile with USB Type as Raw Hid and re-run Kurt's test case the answer is Yes, at least for me. I also tried MTP_Disk and Serial_MTP_DISK and it failed as well. EDIT: Maybe a few...

Just did the exact same thing and can confirm it is working!!!! :)

Paul - is that path right or should it be ...\AppData\Local\Arduino15\packages\teensy\tools\teensy-monitor\1.56.53 thats where teensy-monitor is located for me?

I can't be 100% sure but don't think your pins are not aligned correctly between the T4 and the audio shield. See audio shield pinout vs your picture:
28960

Particularly note pins on the audio...

@defragster

Had similar problem when I installed RC8 from the zip (pretty much the same process you did). When I first did installed it and tried to run it did the exact same thing as you...

Ok you all got me curious so decided to run a 3 basic sketches that I pulled off the web. Note: I am running on a T4.0

As @KurtE mentioned you don't mention what fonts you are using. Just a couple of things off the top on my head based on the RA8875 library included in Teensyduino.

First setFontScale() method...

Very good point with the expected acceleration on a rocket vs car/drones etc. Should have registered that since you are using the ADXL375 versus the ADXL345!!! Wondering to self how something like...

Oops thinking about prints. See https://community.platformio.org/t/is-sprintf-thread-safety/10360

Short answer is no. Sprintf goes to serial and as I mentioned should be wrapped in a serial mutex

Glad you got it semi working. Was beginning to dig into the code yesterday but got myself confused with the way its all set up. Is interesting when I was looking at some existing designs it looked...

Yep that was my reaction as well.

Yep just confirmed getting those errors. There were some changes to DMA code after initial testing but never reran the Demosauce was testing with attitude indicator and uncanny eyes

Thanks for posting the code - think it will help us in trying to help you. I haven't done much in model rockets in years so bringing back memories. Only played with Estes/Centurion etc type rockets...

Know you said the code base is large but maybe if you post the code we can see something or suggest some modifications. We are just guessing at this point. At least for me I have put several sensors...

In your description you described that you are reading 2 accel, a gryo and barometer plus doing quaternion math in the same thread. Then in another thread you are doing the datalogging of I am...

It is interesting that @defragster brought up using FRAM instead of FLASH. Right now you can't use a FRAM chip with QSPI as far as I remember only SPI. It is probably a bit slower but you can still...

Sounds like progress and you are having a lot of fun. Going to interesting when you get it completely integrated - then the fun begins to see about using it with MTP :)

You could try the font editor from this post: https://forum.pjrc.com/threads/54345-ILI9341_t3-font-editor?highlight=ili9341+fonts

To use it looks like you have to download the ttf files for...

The answer to that question is it is Teensy Model dependent.

Teensy 4.0, 4.1, Micromod and Teensy 3.6 are not 5v tolerant so you would need a level shifter. For level shifters there are several...

Think the contrast is excellent for such a small display and the off-axis performance good as well - titled it about 80 deg (just a guess) and was still able to see the display clearly.

I pushed your updated version to the repository along with the tft_picture_viewer sketch you updated for the GC9A01 display.

@defragster - sorry just saw the post. Yes @KurtE incorporated those changes into his fork of the SD library. Not sure if its been incorporated into Paul's master SD yet?

Ok finally got a chance and downloaded your latest changes seems to be working as long as the cards are in the Builtin slot on Teensy start up. If its not and you insert a card it does recognize...

@MichaelMeissner

Have no idea to be honest - been so long here as well since I played with those displays. Been busy with other stuff besides Teensy today :)
