You may have got confused with naming the Serial Ports.
The Rx/Tx pair on the top left, pins 0 and 1, are Serial1. On the Uno/Mega I suspect that the first Hardware Serial port is Serial2 whilst on Teensy it is...
Might be worth updating the web page.
Are the screws supplied or not? Two pictures show no screws, 1 picture shows screws.
If screws not supplied then thread and minimum thread length should be stated.
It's not good to run time critical systems on Windows since Windows itself does pre-emptive multi-tasking.
I.e. it could be doing other things when you want it to deal with your input signal.
Some many years ago...
In order to load this into excel, copy the text and save it into a text file called excel.txt, for want of a name, anything will do.
Start excel and create a new blank spreadsheet.
Go to Data and select "From...
If you want to remove the Teensy, or the ESP, take a pair of snips and gently cut the headers, pin by pin.
Then when it is away from the PCB de-solder/remove each pin in turn.
Attempting to remove a multipin device...
I suggest you use the Snooze library. Except for the Teensy 4.0 it works quite well.
It does not however support the Teensy 4.1.
You should also bear in mind that the Snooze library KILLS EEPROM access.
This was...
Bear in mind that they are NOT bi-directional, on this chip one out and one back.
That is ideal for what I want for Serial UART.
I have seen circuitry where one chip provides bi-directional data by connecting the...
I haven't got any experience with SPI, but I would use simple UART serial.
It's already done for you and would be so simple to get going.
If you want handshaking then rts/cts is available to you, but I can't...
Just to complicate things further I found this.
Looks good and quite cheap.
No need for pullup/down or any other silly additions. I have ordered 5 from here.
After further searching I found this GitHub entry where someone has successfully used the 8 way device and has published a Kikad PCB design for it. Since you only want 4 ways, you could modify the design by moving the...
I agree, but you said that the TSX0108E worked and the TSB0104 does not.
The LSF010x mentioned above looks good to me. But then I went and bought a TSB0104, so what do I know!!
I've been looking at this problem all afternoon. I will need to do uart 3.3v to 5v and back. I had purchased some TXB1040 and obviously they will not work.
I have just found this LSF010x.
Seems like it might fit the...
If you read the data sheet it does NOT state that pull up resistors are required, but if they are present they should be at least 50k due to the low output drive of the tsdx0104. Ie the device does not have sufficient...
Pictures of the assembled board on Tindy show a different form of potentiometer and judging by the PCB layout it is probably impossible to misalign that sort of pot.
Examination of that type of pot indicates that the...

Why not use a 40 pin IDC cable/socket/plug wired as shown below.
This will result in every other wire being gnd. Also makes it easy making the cable using DIL IDC plugs and sockets.
Oops sorry, I see that Oak Tree LLC is selling through Amazon, but check the prices I think you will see that it is buyer that is being shafted.
Prices for a T3.2 and LC are:-
...
I said UK distributors. Amazon is not a PJRC distributor.
UK distributors are:-
Cool Components, HobbyTronics, Oak Tree LLC, PiHut and Pimoroni.
They are listed here.
Even by using an extended partition which can hold other partitions, I still believe that the total number of partitions on an MBR formatted drive is 4.
A GPT partition can be formatted with up to 128 drives.
If speed is not paramount you could consider a PCF8574 I2C 8 bit expansion chip. The current per pin is 25ma with a total of 100ma for the package.
There are also 16bit versions viz MCP23017. This latter chip being...
Your data on using Serial.begin on this page https://www.pjrc.com/teensy/td_serial.html states that:-
"Serial.begin()
Initialize the Serial object. The baud rate is ignored and communication always occurs at full...
A possible solution could be to enlarge Serial.begin() to Serial.begin(baudRate, timeOut or delay) where Serial.begin(baudRate) /Serial.begin() defaults to a timeout/delay of 2.5 seconds, or whatever is determined to be...
You could consider one of these. It provides 5v (and 3.3v) for the Teensy. It is powered from a usb psu. You could solder a wire to the battery connection and shut down and save data to sd card, or whatever, when...
