Glad you got it to compile. I guess now you know how data and directories are arranged for programs/sketches and libraries. How are you trying to listen to the sounds?

Copy ALL THE FILES, but NOT the audio-guestbook directory and paste them INTO the audio-guestbook directory.

Ok, look to see if the files play_sd_wav.h and play_sd_wav.cpp are in your audio-guestbook directory.

Oh dear, I have just compiled the copy I downloaded to my PC without any error. Do you have this line in your code: #include "play_sd_wav.h" // local copy with fixes? I have just commented it out on my copy and get...

Ok those should be fine.

...as to where to put them... Your programs/sketches (whatever you wish to call them) are stored in the directory C:\Users\iandi\Documents\Arduino\. Libraries, which is what MTP_Teensy is, are stored in a directory...

You can get the MTP files from here. Do you know what version of Teensyduino you are running? The above code needs Teensyduino vs 1.57 or later.

Then what do you mean by the above statement? Are you running some other software to read the SD card?

Yes but my argument is if the adc NEVER sees a request to send data then if(Wire2.available()) will ALWAYS return false.

So have you got the audio guestbook to compile ok?

We have been concentrating on the if (Wire2.available() >= 2) { but of course if the ic does not see a request to send then Wire2.available() will always be false. I see that the adc is addressed relatively early in...

SDA1 and SCL1 are addressed as Wire2. You need to change line 308 :- if (!bmp.begin_I2C()) { to include the Wire2 assignment. So something like if (!bmp.begin(BMP3XX_ADDRESS, &Wire2){. NOTE: I am not sure...

Not that I can put any theory on it, but I keep being drawn to a different current draw, without the chip, affecting those capacitors on the I2C lines. But then again I might be completely wrong. An interesting (not...

You could just stick it down on it's back, like LIDs of old (Leadless Inverted Devices) and solder jump leads down to breakout board.

I think you have things in the wrong directories. Copy all the contents of C:\Users\iandi\Documents\Arduino\audio-guestbook-main\audio-guestbook\ to C:\Users\iandi\Documents\Arduino\audio-guestbook-main\ Then...

Quit out of the Arduino IDE. Go into your Documents folder, then into Arduino (Documents\Arduino) and delete all Audio Guestbook entries. Go to https://github.com/playfultechnology/audio-guestbook and download the...

Get one free from the chip manufacturer. It is possible to get a sample. When I filled out a form on their web site they sent me free samples and a free demo board.

Of course the test just carried out is all about writing to the Wire2 i2c. I have just run a test involving reading from a MCP9808 temperature sensor and that works fine on Teensy41_NE on Wire2. Of course where...

Yes, works just fine.

Yes it does. I just replaced i2c libraries you were using with Wire.h and the rest compiled just fine. EDIT: If you are using that external (to PJRC) library then perhaps it is a question for him.

That is NOT using the wire library supplied by PJRC in Teensyduino. Could you try with the Wire.h library rather than the i2c_driver.h and i2c_driver_wire.h drivers.

USB connector pushed in many times and probably not carefully. That is probably the source of your bad connections. Probably about time to change the connector to a chassis mount one as has been described to you....

You might find one of these with it's protective cap more robust in those sort of environments. That is as long as the cap is replaced each time.

See #4 above.

You can use the Teensy to connect to an ESP32 via Serial. The WebServer will be on ESP32 which communicates with Teensy.

I believe Locked Teensy T4.1s are only available BUILT from PJRC.

Have you had a look at SPI.cpp? This might have the answer to your question/conundrum.

It may be that the Teensy is starting up Too Quickly for the MCP23S17's when you start to initialise them. The chips may simple be not ready to be initialised. This is born out by putting a delay at the head of the...

Can I suggest that when you post code that you enclose it between CODE tags using the # button above. It makes your code so much more readable and therefore easier for others to potentially help you. EDIT: You seem...

Then why is it still included with Teensyduino as an example?

If you examine SPI.h you will find that beginTransaction uses SPISetting(clock, bitOrder, dataMode) to setup the SPI port. If you are not USING SPI transactions then set SPI_HAS_TRANSACTION to 0 on line 30 and use...

Yes but will it be included in future Teensyduino?

I have that same erroneous code shown in #10 and I am running Teensyduino 1.58b3. Presumably this code was installed by TeensyDuino. Can it be arranged for the corrected version be installed with Teensyduino?

If you were to examine OctoWS2811.h and OctoWS2811.cpp you would see that the library already uses DMA.

As an aside, why not use something like this. It handles all your keyboard scanning and only requires two pins (3 if you include interrupt).

The Snooze wake up times are rather long for the T4.0. See here.

This post might help you. See post #16 onwards.

See a needed correction to the Snooze Library here.

Yes and deleted all the parameters which you did not require, unfortunately YOU DID NOT delete the digital parameter. As I said I don't know if it will make any difference but without setting up the digital component...

Firstly could you enclose any code posted between CODE tags using the # button as I have done below. #include <Snooze.h> SnoozeDigital digital; SnoozeTimer timer; SnoozeBlock config_teensy40(digital, timer); ...

Any code for the Teensy has to be programmed into the Teensy. You can not just place it onto an SD card. I suggest you read this about getting started with Arduino. Think of the Teensy as a supercharged Arduino. ...

You might find this useful.

Ok, thanks for that. I agree with Patents and Agreements. They are only any good if you have the money and are happy to sue. I used to work for a firm where the Proprietor (before going Public) had an idea and...

The only UK distributor with them in stock is OakTree LLC but they are charging a before tax price of $30.40. I have converted for exchange rate and tax. This is a 28% mark up on retail price! I thought you were...

Could you not use this chip for your keyboard. You could then just use one T4.1 or T4.0?

Did you mean RayMing Pcb Assembly?

Make sure you get a quote for shipping and extra fees before you start, or do a small test run. There are other companies doing the same thing. Of course it would be nice if someone on this board would act as an...

If buying in the US and shipping to the UK you might consider MyUs.com. Register with them and you get a US address. I.e. buy from PJRC giving your US address. Items get shipped to MyUs who then ship them on to you in...

Yes it does say Gold plated on the Male-Male parts. I must say that I had not noticed before. The advantage of the turned pin sockets beside low insertion and extraction forces is the fact that they are very low...

I see. I never use Teensy's soldered in. I use turned pin low profile plugs and sockets like this and this.

I'm confused, I meant use the one that had been using when you experienced problems.

If you wanted to rule out the Teensy, you could put it into your latest PCB and test to see if things are still stable.

Please read the FORUM RULE. Show Source code.

Yes, but you don't have to wait for any reply. Simply flag that a confirmation/reply is expected and pick up that confirmation when appropriate. The confirmation will be waiting in the serial input buffer.

He wants to I don't think your suggestions achieve that.

What makes Paul able to manufacture Teensies without any one copying them?

You could use a Teensy 4.1 which has Ethernet hardware built in. You are going to get some proficiency in coding. Do you have the code (source) for the 3.2 and Arduino?

This is something I found when Googling Haltech Can Protocol.

Usual to put de-coupling Cs as close as possible to each IC across the supply lines.

If it is NOT getting past while (!Serial) it means that the Teensy is NOT seeing the computer USB Serial port. It would be better written as:-Serial.begin; While (!Serial && millis() < 5000){};This will case the...

First of all can you enclose your code between CODE tags. You can insert them into your posts using the # button. It just makes your code easier to read and understand and makes it easier for others to help you....

If you want (true) serial output use Serial1, Serial2 or Serial3. Serial (USB) outputs to USB or Hid.

Or you could consider something like this.Battery based power bank with 5V and 3.3V output and battery charging/management.

Test points as I said. See here.

Test points used during manufacture to test product.

This is the one I have been using and is the one refered to in my post. Obviously you have to be aware of rollover of the millis and micro, especially the latter. Perhaps do some zeroing/resetting each time you take a...

You have the INTerrupt pin on the RV3028. This can be set up for repetitive interrupt. See the RV-3028 Manual.

Yes. Put a BAT54S on the input to the Teensy. Should solve that problem.

Could also check on amount of EEPROM present, if you don't add to the T4.0 board.
