I just got my Teensy's ordered! Was looking at the ref manual and see that at least some of the lp-uarts have the "single-wire mode" that we need for SDI12 communications, so that is a good start. I haven't really dug into the T4's serial code in...

Hi all, yes it's been a little bit. So I guess I lost my Teensy 4's, lol, so I'l order a 4 and 4.1 soon.

You need a buffer big enough for twice the longest interval between yield() calls, plus some margin. It looks as if your code exits loop() often, so if you monitor the loop interval and print the maximum value, that’s going to help a lot. Say...

hi again sir @h4yn0nnym0u5e, I already tested the library, just had some problems installing it earlier but now I have it. Thank you for the modification of the Audio Library. I just had some questions, for the createBuffer(****...

Hi sir @h4yn0nnym0u5e , I will check and try this new library tomorrow and I hope it can solve my problem with audio library. Thank you very much

Hi, I'm trying to use the Audio Library for Teensy 4.1. During testing, my board stacks, and watchdog resets it. Then this is the crash report I'm getting. CrashReport: A problem occurred at (system time) 16:57:36 Code was executing from...

Hi, I'm trying to use my Teensy 4.1 board to output wav files coming from the built-in SD card to a speaker. Upon checking the teensy audio library, Teensy can be connected using I2S to an audio board available for teensy 4x and another...

Hi sir @duff, I'm very happy to hear that from you. I thank you for making this library for SDI-12 communication.

Hmmm, I have been thinking about trying to port this library over to the T4 for a project on monitoring the soil moisture using the a couple of decagon SDI12 soil moisture, EC and temp senors I have. Maybe now is good time to try to do this but I...

Thank you very much for your feedback. Now I don't see any phantom data coming from Serial8, but is it possible to add this line of code after setting the Serial Hardware? Does it clear any data from Serial Hardware during setup()...

okay sir @PaulStoffregen, I think my last option is to port sir @duff's library.

And if I may add, I use 150mhz to reduce the internal temperature. My project is to be installed outside, to monitor the weather condition in our Country (huge project for next year, using Teensy 4.1 if I can port all of my program from Arduino...

Hi sir thank you for your feedback, on my original program, i use Teensy's internal RTC, and every 5seconds, i feed the watchdog. I will try your suggestion and post it here. Thank you very much

My Teensy is connected only to a breadboard, with no wires attached. I'm just trying to test my Teensy board using 150mhz nonstop to monitor the internal temperature but I noticed yesterday it started to reboot non-stop.

I encountered some errors using the hardware serial of Teensy 4.1. When Teensy boot, my code always checks if Serial (in my case, Serial8) is available, but when I'm parsing the received data, it shows no value, and it will stock my Teensy until...

Update, I tried to measure Pin 12 (SDI-12 pin connected to Arduino Mega 2560) using a voltmeter, it measures 1v during idle, and when I hit enter, it registers 2v. Based on SDI12 standard it should be 0v and 5v for mark and space but either way...

Good day sir @PaulStoffregen , I already tried the library but first, I tried to test TXB0108 if it will work with 5v to 3v3 so I tried to test it first with Arduino Mega UART 1. Connected Arduino Mega2560 Serial3 TX RX to TXB0108 2. Connected...

Yes sir @PaulStoffregen , I will use this module from adafruit. I will give you my feedback today. Thank you again sir

Using AVR timer names like TCCR0 won't work. Here's an attempt to port that library using the ARM cycle counter. Rather than try to implement the fudge factor, I just replaced the bitTimes() function with an accurate version using floating...

Thank you very much sir @PaulStoffregen , I will now try to connect a working sensor with Teensy 4.1 and I will feedback you as soon as possible if it works.

Looks like the owner of that library @duff has not logged in here for over two and a half years now, and similarly very little on github during that timeframe as well. It looks like that library is specifically setup for T3.1 and T3.2. although...

Colin's library is the better hardware-based approach, but more difficult to port to new hardware. The software bit bashing library looks pretty simple.

hi sir @PaulStoffregen sorry for the other thread. That thread is for the same application but a different library. Either way, can I ask how to use the timer control register of Teensy 4.1? #if defined(__AVR_ATmega168__) ||...

Thank you very much for the help sir @KurtE , I will try to add check which library is better for Teensy 4.1, this library which uses softwareserial , or sir @duff's library which uses Hardware serial. This is the last library that hinders me...

Hi, I'm trying to add support for Teensy 4x with this library, but I'm not good at tweaking libraries. I'd notice that it uses timer control registers and pre-scalers to define the board. #if defined(__AVR_ATmega168__) ||...

Hi, i have a simple question regarding the do whle loop using teensy board. int x; void setup() { // put your setup code here, to run once: Serial.begin(9600); do { Serial.println(x); x++; delay(1000); } while (x < 5); }...

Hi, I'm trying to port this library SDI-12 for Teensy 3 to Teensy 4.1. My problem is almost all of the components are from Kinetis.h of Teensy 3, while Teensy 4 is using imxrt.h. One component of the library from kinetis.h is IRQ_UART0_STATUS to...
