Thank you, I had seen it before but it is not clear to me which pin I cannot use when I read the frequency. Greetings

Hi everyone, Many years ago I had done a project where I used tennsy3.2 with the freqmeasuremulti library. Today I would like to update that project by putting teensy4.0, but I don't understand if the library is compatible and which pins I can't use. I have to read 6 frequencies ranging from 0...

Hello, I have to do an hour counter in a project and I wanted to use the teensy 3.2 which is on board. my problem is how many times can I write the eprom? if I skid the hours and lack the power supply what happens? thanks

Hello, Teensyduino work on arduino ide pro? Thanks

hello, you do not already have a code where I change only id and date?

Hello to all, I have to simulate a def level of which I am attaching the datasheet. Reading the signal with a P-canview I have the following data: id: 18FD9BA3 dlc: 8 data: 51 FB FF FF FF FF FF FF Id: 18FE56A3 dlc: 8 data: FB 51 00 FB FF FF FF FF Repeat 1000ms I have a...

Can anyone help me!!

hi, I have a problem with teensy 3.2, after about 2 minutes of activity the loop stops I don't run the program. I am attaching the listing, I am at the first schedules, any advice to improve the code is welcome. #include <Chrono.h> #include <LightChrono.h> #include <i2c_t3.h> #include <ADC.h>...

Hi, the problem is that to put the sd I have to disassemble the display due to the limited space. However I make a connector and I carry the wires of the serial to a diverter where I decide whether to program I have normal use. Hello and thanks

I do not know

Hello, What program can I use to do text conversion?

Hello, I have a teensy 3.2, can I make them say sentences with the dac? Can you give me some examples? I don't want to use sd cart. thank you

Hello, I use a teensy 3.2 and a uart nextion display, now to update the display I have to connect it with a ttl usb converter. I have two possibilities N1) that the teensy acts as usb ttl when I have to program the dislpay N2) I have to put some diodes on the rx and tx line so that when I have...

Hi, I use a teensy 3.2 can I put pullup resistors at 5v? What value do you recommend?

hi, I use a teensy 3.2 with an eprom i2c M24256, but I can't write an integer, I get up to the byte (256). is there any library that lets me write and read an integer? did anyone do that? can you send me a working piece of code? thank you all.

however removing all delays I have the problem that when the frequency is 0 I have to wait 5 seconds before the teensy gives 0. There must be some error on my code. I'm not a programmer and I still have a lot to learn.

but I do not blame the library, looking for someone who gives me a straight

Now how is it? #include <Chrono.h> #include <LightChrono.h> #include <i2c_t3.h> #include <ADC.h> #include <FreqMeasureMulti.h> /*Pin 0 Rx Nextion -- Al display 1 Tx Nextion -- Al display 2 In1 -- E-Stop 3 In2 -- ScuotitoriON 4 In3 -- AspiratoriON 5 Freq1...

The problem is when I remove the frequency and the pin remains high by numbers for about 5 seconds?

Hello, Use teensy3.2 with freqmeasuremulti library, but the system is too slow. What can I do to improve response speed? Greetings Vito

Hi, to read adc do you recommend the library or a normal analogread?

Hello, teensy use 3.2, what is important is that I can give 5v to the adc without burning. I do not use A10-11-12-13-14, but all others.

Help please!!!

Hi everyone, Isn't one thing clear to me, all analog pins support 5V? Thank you

hi, ok change the resistance with 150 ohms, but what do you give me to protect the 12 volt circuit?

Can anyone help me?

Hi everyone, I have a problem with adc of teensy3.2, I have to read the voltage but I have problems. What I realized was that I put protection resistors from a 1k and 3v3 zener diodes and when it's reading there are voltage drops. How can I solve the problem? how do I protect against adc from...

theoretically there is no need, teensy 3.2 is 5v tolerant.

Hello Teensy 3.2 can you duplicate without having the source?

Hi, try putting two pullup resistors 4k7 on sda and scl https://www.pjrc.com/teensy/td_libs_Wire.html

Hello, I accept the advice and start hacking. Instead to read 4-20ma sensors that you recommend?

But if the micro sd change the hours change? with the eprom it is more difficult !!

Hello, Thanks for the reply. I have to make a controller for a grape harvester, and I need the eprom to count the hours of operation and I write it every minute, the internal one does not destroy it doing it? I use M24256

Hi everyone, I'm doing a project with teensy3.2 and I wanted to know the maximum input voltage of ADC. After there is a library for eprom in i2c? Thank you all

OK thanks, the frequencies I read are maximum 600hz, so I think I have no problems. Quite right?

Hello, I have a problem with teensy3.2, if I use freqmeasure for 8 frequencies at the same time I can use i2c library and metro library? Thank you

good evening, I have to do an hour meter with teensy 3.2, I had intension to use the internal RTC and an external eeprom in i2c, but I arose a problem the eprom will be destroyed by writing and reading it often. Does anyone have any solution?:confused: Thank you

Hi everyone, I have to do a project that reads 8 frequencies, 8 digital inputs, 7 analog inputs and 6 digital outputs. If I use the FreqMeasureMulti library, can I do the pwm in digital cameras? Thank you?

Which library should I use?

Goodmorning everyone, I have to do a project that has 25 digital inputs and outputs these 25 outputs. The problem lies in the fact that I have to use two teensy with canbus master and slave communication. The two modules are placed 5 meters from each other. Can anyone help me?:confused:
