@mjs513 this may be due to the poor quality GY521.

@kd5rxt-mark yes, this script works for me // I2Cdev and MPU6050 must be installed as libraries //#include "I2Cdev.h" //#include "MPU6050_6Axis_MotionApps612.h" #include "MPU6050.h" // Arduino Wire library is required if I2Cdev I2CDEV_ARDUINO_WIRE implementation // is used in I2Cdev.h #if...

@kd5rxt-mark Just to be sure that I'm correctly interpreting what you are saying, your T4.0 LOCK, when running the I2C scanner sketch, does detect the MPU6050 successfully ??=> YES @defragster before doing that try changing the commented out i2c clock speed in the sketch: I don't know if there...

@marque kd5rxt @mjs513 H Yes, the scanner works well and I have the address displayed in the 0x68 console. No problem on Teensy 4.0 Only on Teensy 4.0 LOCK ( but only the calibration part doesn't work) I get around the problem for the moment by running calibration on the Teensy 4.0 and then...

Hello everyone, I'm trying to run the basic GY521 calibration script on the Teensy 4.0 LOCK, but every time I get the error “MPU6050 connection failed”. The sensor works well because when I run my final script, it reacts well even if the zeros are not good. The same calibration program on the...

@jmarsh thank you for your answer, in this case, I can load a table which contains an image in hex and read it, is that right?

Hello, can anyone explain it to me simply? tutorials, videos, websites?

Hello everyone, my research is really struggling to progress due to lack of skills on my part! (I read a lot on this forum and on Google) I still managed to connect a W25Q64JVSSIM flash chip to my Teensy 4.0 board. I will order a W25N01GVSFIG to have more space. But I've been stuck on my...

Hello, after updating the Arduino 2.3.2 IDE as well as Tennsyduino 1.59.0, test the MTP_Tennsy library with the Example_1_MTP_Little.ino script, my Tennsy4.0 card is clearly visible and I now see the Progdisk and the sflash ( for mine 8MB). now I have to compile my code (6MB)! I don't really...

Good morning, I saw this post talking about it, https://forum.pjrc.com/index.php?threads/how-to-put-a-file-to-extern-flash.74183/#post-336346 but it's not very clear for my skill level

Hello everyone, after a number of tests, thanks to your help I managed to connect my flash chip. now, could you tell me the methodology of what I can do to load a HEX array into my chip? Tennsy 4.0 flash: W25Q64JVSSIM TR (mouser) thank you all for the time you give me.

Good evening Mark J Culross, unfortunately, this does not change my problem, the image is not displayed.

Good morning, I thought about my file size problem. If instead of putting a file in hex in PROGMEM, can you put it in Byte? style: const uint16_t image[ ] PROGMEM = { B11111111, B11011000, B11111111, ..........} ; The same file would be much smaller in storage space. But above all how to...

Good morning jrraines, in my case, with a Tennsy4.0, for my image which is in PROGEM, is it your opinion to do the same?

Good morning, I have made a sketch for you of what I would like to do in order to make myself better understood. Thank you for your help

Good morning PaulStoffregen , I am with Tennsy 4.0

Hello KurtE , the goal is to simulate a kind of GPS (random animation of movement) so a large image where I just take the part which is in the area of the size of the screen. the image format is obviously not recognized as compliant. (it could be that a parameter is not correct. I tried on an SD...

Good morning KurtE, I'm on Tennsy 4.0, I tried on an SD card (on the screen) but the image is too big and the test script doesn't work, the card is recognized but not the photo, the script I use to test it is that of ILI9341_t3 spitftbitmap

Hello everyone, I use a Tennsy4.0 card and a 320*480 TFT screen, everything works well thanks to your help. what I would like to know if by adding W25Q64 to my montage I can put a photo of 2000*2000 pixels (the photo is 3MB), the script that I currently made works well with a photo in the...

Hello, with the ILI9488_t3 library and a 3.5 320X480 pixel screen, is it possible to refresh part of the screen normally and another part with buffering in order to have a faster display Do you also have any commented code examples so I can understand the working principle

Thank you for this additional information

hello, I don't know why but it works now, I had to plug in several pines but not include them in the script.... I will be able to move forward with my project thank you all I connected RST 9 DC 8 CS10 MOSI 11 MISO 12 SCK 13 and in the test script I have RST 9 DC 8 CS10

Hello everyone, I have been trying for several days to get this screen to work with the Tennsy 4.0 but nothing works. I probably have to get mixed up in the connections, could you help me? https://www.amazon.fr/dp/B08CNFWHRN?psc=1&ref=ppx_yo2ov_dt_b_product_details

I should have looked twice when I was testing it separately and it worked. but I questioned my work first rather than the material. ;) Again thank you to all of you.

Hello, thank you all for your help, I found why it was working badly, the signal connection was faulty on the breadboard. once connected with a good connection, my problem had disappeared. I've been looking for three days..... Thank you RCARR I preferred to modify my code inspired by your...

thank you rcarr for your answer, actually I did not think of 3.3V ... I am in 6.4V I tested like this but it stops the console. attachInterrupt(digitalPinToInterrupt(15), test, CHANGE); } void test(){ if(micros()-presmillis >=intervale){ cont++; presmillis=micros(); } }

hello BriComp, thank you for your answer, I don't know DigReadFast, I'll see if I find examples to see if it can help me find a working solution.

Hello, sorry for my english,:rolleyes: I use a teensy 4.0 the outputs numbered 2 to 10 are used to control leds with a PWM symbol. Each led and controlled by a "state machine" with millis functions (9 millis defined randomly by state machine) triggering conditions such as on off long stop short...

Hi sutaburosu, thank you for your help yes indeed, it works better in degrees rather when radian, that's already a good thing:rolleyes: Mais je suis encore loin du resultat rechercher, il y a encore du boulot mais peut de temps de libre en ce moment.

Hello, here is my little help function of the web but I have two problems. 1 / I have the impression that it does not turn degree by degree. 2 / how should I proceed to read the image I have in the program? void rotation_image(){ int largeur = 720 / 2; //taille de limage et centre int...

Hello MarkT , thank you for this information, I did not know, I will watch it with passion this weekend, moreover, with this method, we must be able to keep a certain fluidity.

hello grease_lighting, yes it can do a lot of calculation ... probably for this reason nobody does it but I told myself to see the speed of this library and the asynchronous mode ... why not. Actually I have an image of 720X866 pixels which moves without any problem, see even too fast

sorry for english translation online I'm currently having fun playing with ILI9341_t3n on a 240 x 320px screen, I shift an image of width X and height Y from left to right and from top to bottom see diagonally. I would like to make rotations with the axis of rotation positioned on the screen so...

Hello and thank you for your answers. Indeed the goal is to protect the code even with a chip desoldering, my products are not revolutionary but I would not like to see myself copied, I am rather in a small product niche. Paul, do you have a link and an availability date for your tennsy4.XXX...

Hello everyone, and is it possible to protect a teensy 4.0 in read / write if so how to do it or how do you do it? Merci Jean.:rolleyes:

Hello, after a lot of testing, I understood the error, the mpu was sending wrong information. So I did a comparison with the accelerometer and delete the values that displayed anything. all are working fine now.:D

I spent a good part of Saturday figuring out how to put DAM in my code but I didn't get any conclusive results (I'm not at your level). I even watched the entire video post. I wonder if this solution and the best. in addition to my 2 main functions, which processes the data from the GY521...

Hello Defragster, sorry for the #code .... thanks for the example, i looked, i don't understand how i can do it, i watch this afternoon in more detail. with this way of proceeding, is it possible to refresh just part of the screen?

what I wanted to say, I do not understand how to integrate the DMA of this library in my code // # include <Adafruit_ILI9341.h> #include <ILI9341_t3n.h> // Adafruit_ILI9341 display = Adafruit_ILI9341 (TFT_CS, TFT_DC, TFT_MOSI, TFT_CLK, TFT_RST, TFT_MISO); ILI9341_t3n display = ILI9341_t3n...

Good-morning Paul,;) thank you for your answer, I understand the waiting time for SPI communications, I use the following libraries. #include <SPI.h> #include "I2Cdev.h" #include "MPU6050_6Axis_MotionApps20.h" #include <Adafruit_GFX.h> #include <Adafruit_ILI9341.h> I looked at the ILI9341_t3n...
