    Probably best to keep it simple and use just 1 power bank having ordinary 5V USB power output with 1 USB cable. Every power bank is different. None come with reliable tech specs. Even the claimed battery capacity is usually just a made up...

    That's terrific. This works perfectly thank you! The behaviour with the AudioOutputI2S object is still a bit odd, but I can certainly live with the result using startup_late_hook. (And I have now read about the 3 hooks for future reference.)
  • J
    You could use the late hook function: // extern "C" only need if this is used in a c++ file extern "C" void startup_late_hook(void) { // measure A8/pin 22 here } The Teensy's startup code will call this function right before it initializes...

    @mjs513 are you using the Micromod version or the T4.1 version? https://github.com/david-res/ILI948x_t4_mm This would be the right one. Can you share your setup code for the display?
  • C
    Another thought. I actually only need to read the temperature (pin 22) once before the starting the audio system. (The sensor is used for pitch adjustments, as the unit will be playing along with organ pipes, which change pitch with temperature.)...

    @mborgerson - yeah there are alot of things I am passing and returning 2 as well. Not a bad idea to think about using a struct. Will put it on the todo list - which seems to keep growing.

    @Rezo Now that I finished for the most part with PXP wanted to try your parallel display library. So picked up this display from amazon: https://www.amazon.com/dp/B073R7Q8FF?psc=1&ref=ppx_yo2ov_dt_b_product_details Wired it up to a Micromod...

    The other chip on the board next to the IMXRT is PJRC's T4.x "bootloader" (which isn't strictly a bootloader at all). It's only available from PJRC so they do earn something from the micromods.

    Thanks for the reply. Yes, I am using the 4k eeprom. Below is the output for my current build. The high FLASH and RAM2 use are due to including as many flash-embedded audio samples and the longest stereo delay line I can fit into the Teensy...

    mborgerson replied to the thread T4 Pixel Pipeline Library.
    I saw several post in different forums that indicate that a maximum of 5 arguments is an 'industry standard'. Seventeen arguments (if I counted right) seems to beg for a defined structure and passing a single pointer. In the good old...

    I'm getting this same error!! did you ever solve how to get guislice to work with teensy?
  • C
    Thanks. The serial monitor displays pretty much confirm what I am seeing. Having established that Pin 22 is most likely receiving some on-chip noise, I've gone back to the original scenario I was debugging. The original case was a TMP36 3 pin...

    Rebuilt the circuit on perfboard with the same results. I think the breakout is properly soldered as it stops making noise if any wire is removed. You can hear slight changes in the noise if you change the output frequency so I'm still thinking...

    Thank you very much it works now! I wasn't aware of the member initializer list syntax in c++.
  • KurtE
    Before the T4.1, I did a few of them. Sometimes without it always working. One thing I typically do in a case like this is to use a program to check the continuity of each of the pins. Often times I use a program I have posted several times...

    Unfortunately setting bits 6 and 7 in 0x804d (0xFD instead of 0x3D) did not change the coordinates. So I did the tricky math and that worked: void handleTouch(int8_t contacts, GTPoint *points) { Serial.printf("Contacts: %d\n", contacts); for...

    With Teensyduino 1.59, setting the pinmode correctly is basically now built into analogRead() to avoid the old issue.

    Thanks, I wasn't sure that it was already implemeted. Paul

    i did change to sd card to BUILTIN_SDCARD, i will check with the person who soldered to pcb to see if the wiring is correct, i really hope this works, should have an update by tomorrow
  • PaulStoffregen
    Ah, now I can see you're trying to connect a plain SD socket to all 8 SD pins. That definitely does work on the Teensy 4.0 breakout board. It even uses the same socket. Maybe that board's info can help? On the software side, any of the SD...

    Short answer - your choice. Yes - That would be great. Other option: B0_00/10 - which sort of matches the pins on the left-hand side. Sort of interesting that pins on Left - you show functional names for all of the AD_B0_xx and AD_B1_xx pins...

    For the GT911: register 0x804D bit7 reverses the Y axis, bit6 reverses the X axis. Those bits are marked reserved in the GT9271 manual but might be worth a try... Otherwise just subtract from the resolution values that you set.

    You mean that on the outer "rim/edge" of the board, the actual software pin number would be shown? For example (looking at the board from above): B0_00 [HEADER] 10
