What, if any, commands are you sending to the system via Serial (USB)?

Posting some code, and description of your expectations and actual performance will help others to help you.

Might help if we knew where you are located!

Can you post your code, and be more explicit about in which way it "Did not work."

As a simple solution you could use
#define Wire Wire1 at the head of the .cpp files.

Don't forget to measure the 100 Ohm resistor. With tolerance, it will not be 100 Ohms.

Cool Components have T4.1 with pins £28.99

Here I am, back again, a little late I am afraid.

Ok, P at 80 psi, Sensor resistance (Sr) = 25 Ohm
Current (I) flowing = 3.3V/(25 + 100 ) = 0.0264 Amp
V across Sr = I * Sr = 0.0264 * 25 = 0.66V...

I will have a look tomorrow.

Great, I'm glad I was able to help.
I have developed a library for the Nextion if you are interested. Really it's a skeletal library with the intention that the user modifies/expands to suit their...

The equation will be of a different form. With the Sensor at the top there is a positive slope with a negative intercept. With the Sensor at the bottom you have a negative slope and a positive...

Swapping the resistor and the sensor around gives these results for a 100 Ohm resistor.

Fastest is to pack the data into ONE variable.
Something along the lines pd=x1*256*256*256 + y1*256*256 + x2*256 + y2

3.3V will give 1023, therefore 2.52V will give 2.52/3.3*1023. Likewise 0.8327V gives 258.
You could swap the Sensor and 81Ohm resistor around but you would have to re-calculate the Voltage/Count...

Yea, not too difficult.
When you receive the line to be plotted, save the co-ordinates in Nextion Global Variables in Program.s.
I suggest x1,y1,x2,y2. Set these up as some dummy values at the...

I would suggest that you should wire up the pressure sender something like below:
29064
At 0 psi S1 will be 240 Ohms.
Therefore the Current flowing will be (I=V/R) 3.3 / (240 + 81 ) = .01A ( 10mA...

Thanks, it looks like a good read. Just printed it off.

This link does not work.

I have no done anything with Audio yet but could it be a buffer not large enough?

Works ok for me. VM + VS 22

Relatively simple (I think) just create an instance of bmp passing the correct wire to it. See below:-

//Use this
Adafruit_BMP280 bmp(&Wire1); // I2C
//Rather than
Adafruit_BMP280 bmp; //...

I guess you should have it in a week, unless you chose courier delivery.

Where are you located?

Pimoroni have them, see here.

Surely this only remains true if the Sensor current is constant.

As I understand it the Receiving device on USB is a slave. You asked to move data from RPI to T4.1 (Master to Slave).

As a possible alternative solution you could try a hybrid hardware/software solution using an AND gate.
Look at the diagram below:

"input" is the signal you want to mimic / shorten.
When...

I was replying to your quote

Make sure the SD library in the Arduino Libraries directory is deleted. If left in place it can be conflicting with the sd.h in the Teensy Libraries.

I quite often use the full path to library files where possible alternatives exist as in

It should be free for a months trial. Is there anything which says something like "Activate free trial"?
I use the VMicro drop down followed by "Open existing Arduino Project / New Arduino Project"...

Yea, I gather that it sort of sits on top of the Arduino environment. I think this is sort of confirmed by one of it's configuration options to "Re-scan Tool -chains and Libraries".
It just sort of...

I use VisualMicro and Visual Studio. No problem they can sit side by side with the ino on the address bar.

Does it change to false if USB disconnected?

As I said earlier if you use write you are sending 4 BYTES of BINARY data. If you used print that binary data is converted into MANY MORE BYTES is ASCII text.

num =...

Your program writes to the USB Serial port, then you unplug the USB Serial port.
Don't you think that this might have an effect?

We need to see your program.

Try using mySerial.print. This translates the data into ASCII values. .write just sends raw binary data that is why you are seeing "nonsense letters".

Lora is Synonymous with long range. If you only want to send data it should be fine.
I use these which communicate with the Teensy using the Serial interface.
There are other Lora/Uart modules in...

I really don't see your problem. All the data is there to hook up the display(s) and with the software to drive it!

Could it be an un-initialised variable taking a different state on start-up.

Could this go in the WiKi or be included with the example ino?

The t4.x's have components on the underside of the boards. You MUST leave a gap for these components or have your PCB routed to allow for these components.

I would recommend Visual Micro with Visual Studio. It gives the stability/understanding of the Arduino system with the IDE of visual studio and Teensy Debugging.
I use it all the time and would not...
