Ok, cool ! Thank you:) So the links present in the forum of the previous versions are no longer good :/ .

Hi, I have a big problem with the SDfat library and USBHost. I have a project that needs to use the USB host port for a keyboard and mouse and write to the SD port to integrate the Teensy micormod card. With version 1.55 everything was fine, but since version 1.57 or 1.58B2 I have a strange...

You can by it, but with an HDMI adapter that adds 5V. Afterwards it's like for the rest of the arduino shilds, it doesn't necessarily work as we want. It should be noted that the gameduino offers very impressive capacities for arduino. But yes the gameduino 3X Dazzler has design flaws, and...

I don't know why but from teeny micormod to teensy micromod your program works Frank B :) ! I don't know why it doesn't work with a teensy 4.1 in master. Thank you so much ! I just modified "case 0x26: filename =" TEENSY40.HEX "; return true;" in "case 0x26: filename =" TEENSYMM.HEX "; return...

Thanks everyone for taking the time to try to resolve my problem. My final goal is to use one micromod teensy to program another micromod teensy. I have no choice, I cannot use another teensy model on my project for other reasons. I have just finished building a prototype which will end me...

Hi, I have uncommented the line #define USBHOST_PRINT_DEBUG in the library USBhost_t36.h From what I understood, void USBHost :: enumeration (const Transfer_t * transfer) is not calling With a Micromod teensy in programming mode, and I don't know why. On the other hand, this function is called...

If there is a problem that does not come from this part of the code, but I can't figure out where exactly this problem is coming from. I don't know where the "device" variable is changed. I'm afraid that the problem comes directly from the library "USBHost_t36.h". As I have the same diagnosis...

Thanks for your help, but the detection of the model is not the problem, Here is the code to detect the model while (timeout < 2000) { uint8_t id = bootloader.id(); Serial.print("bootloader.id = "); Serial.println(id); switch (id) { case 0x00: break; case 0x1B...

I continue the tests and investigations because I really really really need this program. I diagnosed something strange. Here is what is happening with the USB_Tester and/or HIDDDevicesinfo programs with a teensy 4.1 as main board. teensy 4.0 on run mod plug on 4.1 -> Device detect teensy 4.0...

For the detection problem it was due to the USBSerial_BigBuffer. now the teensy 4.1 detect the teensy micromod well in the test USBHost_t36> Serial. Now i work on USB Tester program.

Ok, My first problem is when I plug a teensy 4.0 to a 4.1 I see the 4.0 in the test USBHost_t36> Serial, but I don't see the micor mod, even when I press the reprog button. And in the USB Tester program, it doesn't see any device. if (!device) return 0;

Creating a HEX precompiler is not the most complicated, I have already done it. It's sending it from one teensy to another that worries me. I'll take some tests and see what I can do

I don't see a reference for the teensy micro mod in this last one. The last card that appears to be supported is teensy 4.0 Here is an excerpt: case 0x1B: filename = "TEENSY20.HEX"; return true; case 0x1C: filename = "TEENSYPP.HEX"; return true; case 0x1D: filename = "TEENSY30.HEX"; return...

Yes sorry I am talking about the program that allows you to program another teensy card. That one : https://github.com/PaulStoffregen/USB_Tester I'm sorry but I didn't quite understand your last sentence

i, I wouldn't want to brick one of my teensy so I would like to know if this program works for micro mod teesny? As they are very close to teensy 4.0 and 4.1 it could work.

Hi everyone, Here is a first teaser of the project on which I have been working for more than 6 years. As you can imagine I didn't publish it here for nothing, in fact the teensy will be in the game ;) See you on October 6 for more information :) . https://youtu.be/1PXBGHcxVf4

"The actual MicroMod card doesn't have the 3.3V regulator". I did not know it, my circuit which is therefore custom, I had to release the 3.3V to the teensy, so that's most likely the problem. Thank you for this quick response. I hope to be able very soon to tell you more about my commercial...

Hi, I have a theoretical question for you about the teensy micormod card. We agree that there is only need to connect pins V_USB, USB_D-, USB_D+ and GND to detect the card on the pc ? There is nothing need to do with the RESET and BOOT pins ?

Hi, This is what i would like to do basically with two teensy mod. A first teensy mod with an sd card and a bt818 graphics chip. And the second with another sd card with this faith a wifi and bluetooth module. This is not a small part of my project, there will be a lot more to connect to...

No but you can use it to program another one: https://forum.pjrc.com/threads/54318-Use-a-pre-compile-program-on-Tennsy-3-6?p=191141#post191141 And it's work (test on teensy 3.6) https://github.com/PaulStoffregen/USB_Tester

Hi, Do you know the gameduino card and screen ? https://excamera.com/sphinx/gameduino3/ These are the best arduino screens that I know of. there is this mod also compatible with the library. This one goes up to 110 IP/S ...

Personally, I prefer the classic teensy format. I know which will be larger with the 1170. If the MicroMod version is there in addition, why not but if not I prefer to stay on the classic teensy format

Thank you for your response If there is a bulk order from me, it will be in 2021 and I hope with teensy 5.0. But we are talking about more than 10,000 cards, so we will see how we organize ourselves with PJRC ...

Hi, I am also interested to know if this kind of offer exists for 100 or more.

2.- A PCB version with castellated holes for surface mounting. : I'm not in favor of it And it is already possible to do surface mounting with the current teensy.

Hi, Do you know if there is a library that would download a file to an SD card with a teensy from an FTP or FTPS server if possible.

What will be the name of the teensy NXP 1170 with the form factor of 3.6? Teensy 5.0? Teensy 4.6?

Hello, I believe there is an error on this page : https://www.pjrc.com/store/teensy3_audio.html For teensy 4.0 (And 4.1 I guess) it is indicated: DIN 7 Audio Data from Teensy to Audio Shield DOUT 8 Audio Data from Audio Shield to Teensy And I think they are reversed. I think that's what...

I French and in France. We will soon enter confinement mode. Buuut. I'm still waiting for teensy 4.1 ;) XD "but the good news is we saw this coming a couple months ago when it swept through China and we stocked up, in hopes of being able to keep Teensy continuously in stock." : play well Ps...

Hi, When is the release of teensy 4.1? The teensy 4.0 is really but really too small, it doesn't have a lot of I / O

Nop. The 3.6 format is quite good. Three rows make it very tall. Why not two but no more.

Precisely, these graphics chips have a big defect which is to have a very limited instruction number compared to the power of the chips (from 1000 to 2000 instruction around). This is due to the fact that the CPU sends in a well-defined part of graphics chips the instructions that it will have...

Hello, To start I would like to say that I am impressed by the work you have provided. Do you think it would be possible to adapt it for the gameduino 3x and more generally for the FT81x and BT81x chips? They have a rather particular functioning but it has the advantage of managing large...

thank you for your help but my library is changed so it was not possible. on the other hand I managed to solve my problem by modifying the line : void copy(const PROGMEM uint8_t *src, int count); to void copy(const uint8_t *src, int count); I don't know what is the purpose of "PROGMEM"...

Hi, i have a problem when i use a GD3_SDIO library on a teensy 4.0. this problem is related to the migration of the teensy 3.6 to the 4.0 and in particular the library SDfat I have a problem with src in general and copy but I don't have a proficiency on the library sdfat so I can not help you...

Thank you but it's even worse, it's bigger and it's always with teensy3.6 normal so too expensive. (2*40€ + the price of the module). Against 40-60 € for a custom card with the 2 teensy reproduced above It's for a portable system that I work.

Thank you for your answer, I actually buy an NXP evaluation board for the RT1020 chips, I'll be able to even by myself even if making it arduino conaptible is complicate. On the other hand, using teensy cards in motherboard / daughterboard mode and just imposible, it's too big not adaptable and...

Hi, There is a question I ask myself. Is it with the JTAG bus that the M0 programs the M4? or is it another protocol?

Hi everybody, Since now a lot of time I work on a project (a Gaming console). This is based on two teensy 3.6 and that since I day of their release. At first I did it for fun but I realized that this project was becoming more credible to the point of selling it. Of course this requires...

IT's WORKS!!!! :cool: I do not know why but by doing the measurements with my old oscilloscope on the MLK02 the MK66 is awake and all to work normally. Sometimes I had to start again for it to work again but now for a one week I do not need any more. I'm still not sure why but it works but it...

ok, I deepened my diagnosis. I did tests with 2 different MLK02 and tested the conections. The pin rest and Program it is well to connect to the MKL02 and it does not short to GND. When I feed the chips in 3.3volts the program pin while floating and the reset pin is at LOW (0 volt). I already...

Hi, At this time i have the case where the program pin is at 0volt. I was able to send a program once but after nothing. I tested all possible combinations with the button programe and reset but nothing happens. Is it possible that a fault on the MK66 blocks the proper functioning of the MKL02?

Thank you very much for your help. The voltage goes well to 0 or 3.3volt in function of the position of my buttons I will check but it seems to me that this is actually what I had to observe, the reset does not pass low when the program goes low. And if it is the MKL02 that does not respond...

Hi everybody, I corrected the problem on my circuit board, that said my pc detect well something on the USB port but it is not the teensy. I don't know what it is and I don't know how to solve it. I try with all the combination with the reset button and reprogramming but nothing is done. The...

yes but I already try to cross the cables but it did not change anything. I will recommend a PCB with the correction on the voltage of the USB1, connect the DP pin on the DP and DM on DM. and connect the VREG_OUT. I have already made the changes but before that I would like to have your...

Hoooo sh*** In addition I had seen on the page of the store as it was necessary to connect this pin. I forgot it. Thank you Paul. I will try to connect it with some stuff. As we say here "j'ai le seum". Anyway thank you for your help. I hope the problem comes from there.

PS yes I noticed errors including the level of the retention of the usb 1 but nothing vital to the proper functioning of the MK66

Here are the parts of the circuit that pose problem. This is my first PCB custom so it's not very nice to see but it will function. And don't laugh ;) I tried every combination with the reset and reprog button The reset of the PCB filled with other function and the part USB hub function has...

Thank you but I already read well and re read what was there on this page.

Hi everybody, I created my custom teensy 3.6 card with a four layer PCB. I solder the essential for the power supply, the USB and the MKL02 that I have desolders of an original teensy 3.6 await the delivery MKL02 sold directly by PJRC that I buy. But delivery to France will put at least 2...
