    sRGB565 replied to the thread Game Console with iMXRT1062.
    Finally got around to PCB design. We took the Gen. 5 design provided by @Dogbone06 and redesigned it for our current console design. However, I have a few questions. I'm curious about this, first of all: Why is there +5V running under the chip...

    I've found some info on how to change the i2s pins for Teensy 3, but no real forward way for Teensy 4. I think I know the place where it needs to be done, but there's probably more to it. In file libraries\Audio\output_i2s.cpp CCM_CCGR5 |=...

    Does this mean the 1062 wasn't fuse configured and updated? Would the 15 Sec Restore complete this? @bhaskar was this tried?

    Another thing to check, probably a long-shot, is whether you have anything driving the IMXRT1062 pins before it starts the power up sequence. Perhaps other devices that power up separately?

    As a student, Openprof has been incredibly helpful. The free physics textbooks available on the site are comprehensive and easy to understand. They have been a great resource for my studies, saving me both time and money. Highly recommended for...

    Thank you all, pretty good idea. A lot of EEproms are not available this moment I like to use this one W25N01GVZEIG (Mouser nr. 454-W25Q512JVEIQ) will this go to work with a Teensy 4.1 ? Best, Johan
  • PaulStoffregen
    Can you measure the VDD_SOC_IN voltage? If the last stage of the power up sequence is working, it should be 1.15V or 1.25V. Maybe also check the voltages on VDD_HIGH_CAP, NVCC_PLL, and VDD_SNVS_CAP. If the board truly has completed all stages...

    For context, here is a trailer I have just reconditioned , using APA102 LEDs , and it draws anywhere between 30 to 60amps! Notice the large Solar Panels and Battery Boxes needed!

    Hi All, I am planning to try this. I have 200 of the new ws2811 26mm LEDS. Here is a pic of them: And I am planning to place them in a grid of 20 cols by 10 rows. as follows: What I dearly need to do is limit the amps draw. I am in the...

    Yes, both MKL chip and the MIMXRT chips were new, from PJRC. Maybe I would try to remake the board once more.

    Was the MKL chip purchased brand new? Not taken from a different board?

    The CD stuff is a bit of fun... when I get around to it I want to write an ISO9660 filesystem library, so the files can actually be accessed. But in the meantime there's an example that can use CD drives to play audio, and if they have an SPDIF...

    Another quick update: @mjs513 and myself have been doing some testing with this and as the library now builds for both Micromod and Teensy 4.1 We (he) renamed the library up on github. The current Project and branch is up at...

    Dear Teensy community, I am happy to share a little project I've been working on in the past few months :) I have designed a PCB for easily wiring 8 LED strips on top of one another to form a simple grid. I named the PCB the 'Octobridge'...

    I should also mention that I get the same results on a factory Teensy 4.1, eliminating the custom PCB. I'm compiling on a Mac with Apple Silicon.

    Angelo replied to the thread Long time log on SD card.
    One source of problem would be SDcard socket. The contacts could/would oxydize. The scenario proposed by defragster is very good. You could also use flash connected on normal SPI or I2C. Using 2 parts, each on its own SPI or I2C, it would give...

    OK I've managed to demonstrate the weirdness in a much clearer way, but first I've simplified everything right down to just a fresh copy of the Teensy core repo (master branch), modified with one extra pin to eliminate most of the potential...

    Thank you for your reply. I also tried the file 'blink_slow_Teensy41.hex', but the issue is same. [After pressing the program button, the LED blinks 3 times while PC showing the chip] Is it possible that something is damaged? The issue is the...

    You tried to upload a blink sketch for the Teensy2. Try the sketch for Teensy 4.1 (ends in 41).

    Thanks a lot for the help. After fixing the crystal connection it seems the errors are gone. However, I am still not able to upload any program. When I connect the board, the PC gives the sound. When trying to upload with the program button, the...

    We would need to see what your digital_pin_to_info_PGM[] struct looks like (in digital.c) to see how the extra pins are being handled, sounds like they are not correctly implemented. Everything that pinMode() touches comes from that struct.

    Thank you for offering your help. I changed the interface numbers now for the interface combinations USB_MIDI_AUDIO_SERIAL, USB_MIDI16_AUDIO_SERIAL and USB_EVERYTHING. However, USB_EVERYTHING doesn't not work for Teensy 4 and I was not able to...

    Yes it's just a very consistent typo 🙈. It's the right way around in the sketch.

    defragster replied to the thread Long time log on SD card.
    Not seen any long term 2 year runs to an SD card noted? Given it is T_4.1: One idea would be a Bottom soldered QSPI FLASH chip - 64+MB would hold 2 years of logging and could be sent to SD card daily or weekly for backup and retrieval that would...

    A follow-up on something really strange I've since discovered. I have a custom Teensy 4.1 PCB that uses an additional 32 pins for a total of 87. The extra pins have been working perfectly as basic GPIO in/out pins, using only with pinMode()...

    I'd imagine there's no problem with just changing interface numbers around, so long as you keep everything unique. The code should be independent of interface number, as that changes depending on the USB option selected anyway. I think. I've got...
