Downloaded, and rebuilt MTP picture viewer and it still works :D Note: with current IDE releases, As soon as I close the preferences with the updated boards list, Arduino automatically reloads the board file, and detects that Teensy board can be updated.

Hi @Bill Greiman, looks like you are having fun. So far I have not tried Rust, but have been playing with Zephyr for a while now, including the Arduino boards which builds on top of Zephyr. Currently there is some Zephyr support for Teensy 4.x boards, although mostly barely limping along...

Morning all, I installed it last night and tried my main MTP sketch (picture viewer) and it did not show any of the issues. But again it times out: void setup(void) { // mandatory to begin the MTP session. #ifdef MTP_TEENSY_H MTP.begin(); #endif // Keep the SD card inactive while...

For me, I would probably use it in one of the simple boards @Paul has made in the past, like: Would be great if Sparkfun sold some like these. Especially the later ones that have qwiic connectors. Sorry for the dust in the image

Sorry, wondering if this chip also does Bluetooth? Again it looks similar to the one in the Nicla Vision and probably others: From the earlier schematic: From the Nicla Vision schematic: https://docs.arduino.cc/resources/schematics/ABX00051-schematics.pdf And I see signals setup for example...

How Would I mount this? Above or below the Teensy? Access to the USB Host pins? Other through hole pins on Teensy? SDCard? That is suppose I wish to use this with an Audio board (mostly likely not be) and have USB Host pins as well as access to SD slot

yep, Found it the last place I looked 😉 Looks almost similiar: Although the Nicla Vision has: SS4325012 part and this one has: SS2211007

Thanks, so far I am not seeing it... Will look again later

I am trying to remember which wifi unit that you are using now... Any photos? Sorry been a bit distracted with other things. Might be fun to start testing again. And believe it or not, sometimes my desk/work area is not overly organized :D I now have two Atolla USB 3 hubs 7 switchable USB...

I pulled out the DB5 that has my own shield on it and am running HiLow test on it, and it is seeing other pins. Have not verified all of them, but at least some of the higher ones match... Sorry have not done a lot of testing on it yet, been busy, with trying out the requested changes to the...

:D - It is a pain, but also some interesting stuff as well. Sorry, I am also distracted, as trying to get a Pull Request into Zephyr code base, for changes to the Camera Support. I both appreciate and curse the process of getting stuff in. It requires code reviews from multiple people, Picky...

I have done some random building of some of my old stuff. Not running into too many issues. Although my projects that use my old BioloidSerial library are failing to build. The errors are not caused by the changes to this release, but due to a release or two ago, with some Hacked up code...

Quick update: I know there is about %.01 chance of any of this stuff merging, but I know a few may want to play with it. I could not simply rebase... Could not squash commits... So I created a new branch and cherry picked: https://github.com/KurtE/cores/tree/variants_new Not sure if it works...

Understood - which is one reason why my boards are sitting on the shelf and/or in boxes in cabinet...

I am trying to decide if I have it in me, to update my Branch variants_override PR #750 to be up to date. Looks like the last time I did that was two years ago. My guess is it is still unlikely that any of this stuff would be pulled in to the main branch, but miracles do happen :D EDIT: And...

Note with Zephyr, potentially a lot of this is already done... That is there are already a couple of boards with Zephyr support like: https://github.com/zephyrproject-rtos/zephyr/tree/main/boards/nxp/mimxrt1170_evk...

I have not looked too closely yet, but are these boards offered for sale? price? Arduino support? Zephyr support?

In the Teensy cores, all of the directories, directly under cores with the name USB_ are for Teensy 2.x (maybe 1.x as well) only At times I wish we would split this up into a couple of different installs, like 2.x and 3-4x... But... The USB support for Teensy 3.x is under the directory...

😲 :oops: Sorry my eyes glazed over and the it was setFrameBuffer... A bug, not the error message was not overly helpful, but... Anyway pushed up changes

D:\temp\.arduinoIDE-unsaved202653-12208-3mqc01.sa1k4\doubleBuffer\doubleBuffer.ino:48:22: warning: the address of 'fb1' will never be NULL [-Waddress] 48 | tft.useFrameBuffer(fb1); | ^~~...

pushed up. Which sketch, which board? EDIT: I tried t3.2 looked like similar uninitialized, which was half way correct. That is the first time that function is called, they are but called again right after that when the next call in the init sets those and then recalls... Pushed up.

Where, is this? I did not see it in my build. Which Board? But maybe not calling function you are...

Yep, I believe it is supposed to be: void drawChar(int16_t x, int16_t y, unsigned char c, uint16_t color, uint16_t bg, uint8_t size_x, uint8_t size_y); void inline drawChar(int16_t x, int16_t y, unsigned char c, uint16_t color, uint16_t bg, uint8_t size) { drawChar(x, y, c, color...

Installed on Windows 11, and tried a few programs, so far so good.

I now added whole teensy areas of Arduino15 to the don't scan so now it builds. Not sure if you picked up the flexio changes or not, should probably look.... For those of us who are used to programming c++ back in the stone age, what new things does the updated toolchain provide? Should...

I now excluded the <arduino15>/packages/teensy So now it runs without checking...

Should mention, that Norton is having a fit over this... Should only take a few hours.... Oops meant to put this in: https://forum.pjrc.com/index.php?threads/teensyduino-1-62-beta-1-toolchain-update.77923/

My guess is it has to do with your changes to the library to change: Before when it was true, it did not include a file if no one references it... Now it includes all of them...

Actually your entire Issue was: Sorry, but there simply was not enough information to go on. I have not touched this code for a couple years now, and a lot of it, was done something like 8 years ago. And you are probably right that the mode SPI_MODEx was probably never implemented. The only...

I don't think you can attach two interrupts to the same pin. Probably last one wins. You might register one per pin, with the mode: CHANGE and then detect which edge it is. Edit: option 2 - Register the first one you expect, lets say RISING, and in the RISING function you do an...

Sorry, I don't typically click on things with spoiler and not seeing where it is linked to. Could be spam or malicious or perfectly innocent. Others here may be the same. Suggest that either include them directly or the like.

Which example sketch? LittleFS_Program_Simple_Datalogger-dates ? On What Teensy? Which version of Teensyduino?

On my old and only Mac (Mac Book Pro early2013), there were things that I could not install on it, including Arduino App-lab (Uno Q). Apple dropped support for these on later OS... I am trying to remember what I did, but used a utility to allow me to install Sequoia 15.7.3, So I am now able to...

There is a Serial Emulator USB type that Paul created as part of the Teensy code base, that is used in several of the USB types that do not include Serial. I am not sure if it is documented anywhere, except the code. Earlier I added support into the USBHost_t36 to be able to use it if you...

Quick note on pin IRQs, is sometimes I have played with using pin 34 on T4.1 34 RX8 2:29,3:29 2.29 B1_13 CSI_VSYNC Which is on GPIO 2.29, so I might switch pin 31 back to Normal mode (so GPIO 2, not 7) And use the IRQ: IRQ_GPIO2_16_31 Which pins are fast is setup in startup.c...

I looked in my cabinet in box and found I still had the 3.97" version connected up to T4.1 and so tried running my example sketch Kurts_NT35510_t4x_p_FB_and_clip_test... and it looks like it still works. Could still be some bugs like fillscreen in some cases did not do whole screen or maybe it...

Sorry, I have not looked at this stuff probably going on 2 maybe 1 3/4) years now... Wild guess or what I would maybe try add: lcd.setBusWidth(16); Before lcd.begin()... or Maybe just before your call to setFlxIOPins (which you probably don't need as those are the default)

From this I am assuming you are trying to use an USB C to some form of adapter to the USB Host pins? You might try one of the USBHost Serial examples to see if you get anything...

My quick look and I did not find any HD44780 that are 24x2... so probably not much help Did find some on EBAY that are BOLYMIN BC2402A Not sure if that is similar?

I commented on the FlexIO PR that my quick look, that it looks reasonable, but that @PaulStoffregen probably should also take a look and if it looks fine to him, great will pull it in

The issue with creating several new threads on related issues is that a lot of people may not see what has or has not been suggested on the previous threads and can lead to a lot of duplicated effort. And it looks like the same starting example code. looks like you also have another granular...

Looks like this is a semi-duplicate of the thread ? https://forum.pjrc.com/index.php?threads/may-i-contact-to-bleep-labs.77791/ Although probably a better name for it. Good luck

The first like was the commit that Paul did to his Audio library to add the text of the bleep labs... I was suggesting you might look back to that and see what other Pull Requests Paul did at about that time. I was also sort of suggesting you go look at his web site: bleeplabs.com Which also...

Sorry, I am not an Audio person... But I looked up at the library, and it looked like the comment about "Bleep Labs" was made by Paul like 8 years ago. https://github.com/PaulStoffregen/Audio/commit/f702d20ea591572313dccdc0c8d4add48517eea1 You might look around and see what other commits were...

Sorry I don't use VS Micro... but: I edited the file <Arduino15>\packages\teensy\hardware\avr\1.60.0\cores\teensy4\MPT_Teensy.h I changed the section like: // modify strings if needed (see MTP.cpp how they are used) #define MTP_MANUF "PJRC" #define MTP_MODEL "Kurts_Teensy" #define MTP_VERS...

This depends on ... That is for example with Teensy 3.x boards, display drivers using hardware CS pins for both CS and especially DC can get a very significant speed up. Why? note I am going to use psuedo names for commands. For example drawing a point: the code may output: <SET X> x1 x2...

Actually I may be wrong... I have not played much with the Scrolling stuff, built into the chip itself. That is command 33h Note the description continues for about the next 3 pages in the PDF... And then there is Command 37h Which also continues on the next page: Looking at the sources, I...

It has been awhile since I looked at that sketch. I don't remember if all/most of these displays support the MISO pin, to be able to read the contents of the memory back, to then output... Or if that was required on these chips as there may be some support into them... @mjs513 do you remember

In the ST7789_t3.cpp file you will see the function setRotation void ST7789_t3::setRotation(uint8_t m) { beginSPITransaction(); writecommand(ST7735_MADCTL); rotation = m % 4; // can't be higher than 3 switch (rotation) { case 0: writedata_last(ST77XX_MADCTL_MX | ST77XX_MADCTL_MY...

Sort of interesting that there is a new thread up on the Arduino Forum about what the heck is this Teensy 4 Security stuff... https://forum.arduino.cc/t/teensy-4-security/1435688 Including instructions by PerT on how to remove it if you don't want it...
