Yeah i got that too. And they linked to this discussion for the spec's on the new board. I thought that was kind of crappy.

charnjit what is the full path for the location that you found it?

Can someone guide me in setting up PIO? I tried installing visual code an the install hangs. Is there another UI, I have visual studio? Also how do I set up PIO? Everything I have read seems confusing??

Gabriel M, could you tell me the Name and where you got your 4" display and what drivers? I'm looking for one to connect to a Teensy 4.1 Thanks!

Thank you for your answers. Pretty much the only one I have found is the adafruit https://www.adafruit.com/product/5794 display. I guess i will have to use the ESP32 as a man in the middle, seems there is no other options.

@JimSoft, did you ever get this working?

Can anyone recommend a teensy 4.1 compatible 4inch x 4inch TFT LCD touch screen? I'm wanting to add one to my new project. Thanks

@mjs513 Can you tell me how you send a reset command?

Oh, yeah. Thanks

I asked ChatGPT and it seems that this works - SD.sdfs.ls(&Serial1, "/", LS_R); Is there a reference to MTP somewhere that has this kind of info?

Thanks Joe! What is the MTP function to list files to my serial output? I previously used Serial1.println(F("\nList of files on the SD.")); sd.ls(&Serial1, "/", LS_R); Serial1.println(F("")); But that doesn't work any longer with Paul's version I guess?

I the documentation I've read it said it needs to be run when there is a change to the file or when the file is closed? Is this wrong? And what does it do anyway?

????

It was a monitor that had usb and card reader capability.

Well I don't know how, I certainly didn't mean too. Also it's just a single drive I. H was another device. It also shows up when i use a MTP example program. I think it has something to do with the Serial + MTP Disk (Experimental) setting

Question, when should i use MPT.reset()? Is it needed?

I know this is an old thread but maybe someone can explain why when i use MTP, the teensy shows up under this pc but also two additional drives show up in my drive list, I and H? When i click on either one windows says please insert disk. It's not an big issue but can anyone explain why and if...

follow-up: ok reloaded teensyduino and reset (agin) and it's working now. Strange

After trying to load the above code i get this error again Unable to open COM3 for reboot request Windows Error Info: Access is denied. more ideas... https://forum.pjrc.com/threads/40632?p=126667&viewfull=1#post126667 Teensy did not respond to a USB-based request to enter program mode...

ok got it back after several resets... Can someone look over my example program and see if there is anything that could have screwed it up?

I tested with a new teensy by plugging it into the usb and it behaves as it should but i have not attempted to program it as i don't need it broken too

I was messing around with MTP and made the above changes to MTP_Teensy.h with one of the example programs and now the teensy 4.1 won't show up as a usb device in Arduino. The comm port (com4) shows but not the HID. I can't program it any longer. Did i break something? Error is Teensy should...

FYI - I'm using Pauls version. Can you tell me where i can find that file?

I think my question has already been answered but I can't find it, how can i change the name MTP shows from teensy?

I resolved the issue by doing this... static void Bypass() { Serial.println("in bypass function"); //while(digitalRead(bypasspin) == HIGH) for (; ; ) { if (Serial1.available()) { // If anything comes in Serial1, Serial2.write(Serial1.read()); // read it...

@defragster, I replaced the while(digitalRead(bypasspin) == HIGH) with with while(true) or for( ; ; ) it is working as expected in my expanded code with either! It seems to be failing in the digitalRead(bypasspin). So now, how can break out of the endless loop with the pin going low and what...

Connection are as follows, serial1 is connected to comm 1 on a computer through a rs232 ic. Serial2 is connected to a secind computer serial port the same way. I am using a switch to bring pin 3 high. Debounce should not be required. As the idea is to leave the main loop to loop in characters...

I fixed that,that was a stupid mistake. so I fixed that and it works. I expanded the code to what i need it to do and it still doesn't work. Can you see a reason why this would not work? It jumps in when the pin is high from this call in the loop(): if (digitalRead(bypasspin) == HIGH) {...

Passing serial data from serial1 to serial2 in an loop endlessly works fine like this; / the setup function runs once when you press reset or power the board void setup() { Serial.begin(9600); while(!Serial); //wait until serial is opened to run Serial1.begin(9600)...

thanks Paul!

is there another method to capture a momentary button press?

I plan on using it to send a zero totalizer command via modbus to a flow meter using a momentary button switch. Do you have another suggestion to do this on a button press?

In the following program const int buttonPin = 2; // Pin for button void buttonISR() { Serial.println("Button Pressed! Sending message..."); delay(1500); } void setup() { Serial.begin(9600); // Initialize USB serial for debugging pinMode(buttonPin,INPUT); // Set pin as...

Needed the ads1118.begin() in setup. I looks like it is in the library and I assumed it would be called when a read ADC read function was called but it isn't.

Nevermind, after further work I found the problem.

I have two programs, one for a modbus master and the other to read the TI ADS1118 ADC each one works as expected. I combined the programs together into a single program and the ADC part seems to fail on SPI but, again independently they both work fine. I added debugging serial prints and it...

Does this library include CRC check calculation? And what about Endian (big or little)?

Nevermind, changed the sample rate and that made it a lot faster! Thanks Paul!

Ok i changed the buffer size and the prints are quite fast but the program is slow in the ADC function i guess... Can you see anything that would be slowing it down to about 1 second for the function to run? // Function to read pressures and temperature from the ADS1118 void...

I'm doing a lot of serial writes to USB and three other real ports and it seem to slug down my program. What are good settings for buffer, size? What are the min and max?

Is there a method to send the same data out to three serial ports simultaneously?

this program compiled and ran just fine and now it won't and is giving these errors: D:\ChuckW\Arduino\Projects\Ads1118\Ads1118.ino:19:19: error: no matching function for call to 'ADS1118::ADS1118(int)' 19 | ADS1118 ads1118(CS); | ^ In file included from...

ok, thanks. I had to uninstall and reinstall it to be able to compile, it was stuck and lost all of the boards in the manager. Thanks for all of the help!

What do you use to develop?

Now Arduino is stuck and says downloading index: package_0.60.3_index.json. I rebooted my computer and am getting the same message.

ok thanks i'll do that. So i shut down arduino and restarted it. Did a reload and it said it was compiling and uploading in the message line but there were no compiler messages and it acted like it was hung. I did a user abort, shut down arduino again, restarted and it worked this time and now...

Aw damm, somehow the board got changed to Arduino SAM under tools/board. I never work with that or any arduino board (only teensy 3.2 or 4.1) and it always is set to Teensy 4.1. I'm starting to think 2.3.3 is still buggy. Sometimes the settings change and i have to look over settings i would...

Yeah something is wrong, it's not reading the hardware correctly, no matter what the input voltage i get maxed out readings i.e. 32768 bits

Thanks Joe! yeah I saw that, I am using teensy. So just now I added #define CORE_TEENSY in the ADS1118.h to see what happens and now it compiles again. Is the SAMD reference a problem? Like I said, nothing changed that i know of in the lib? Baffling. Now i guess i need to see if the hardware...
