    FreqMeasureMulti Library on T4.1 or Micromod - which pins for 8 independent signals?

    I am transferring my project from T3.6 to T4.1 / Micromod (not decided yet). I want to measure frequency and/or duty cycle of 8 independent signals and I am a little confused about Paul's notice in the description of the library: As you can see I am not very familiar with the FlexIO/-etc...

    T4.1 - connect bottom pads and SD-Card Pins to other PCB

    I am thinking about migrating my current (though neverending) project from T3.6 to T4.1. Unfortunately I made use of almost all Pins of the 3.6 so I am running in some issues - which means I have to use every single pin T4.1 has to give. I am sure I am not the only or first one who asked this...

    About 1.54" TFT 240x240 pixel with ST7789 and 22 pin connector

    Even better: This display works with Pauls ILI9341_t3 library. In fact I managed to use KurtE's ILI9341_t3n library to drive this display including its frame buffer functionality and at full 30MHz SPI Speed. There are only a few things to change, mainly one register (MADCTL, 36h) in the...

    Extended Pin Numbering

    Nice to see some progress here. I am not able to help with testing at the moment, but if the PIN number card has to be changed for any reason I will do that.

    Adafruit SSD1306 multiple instances issue?

    I think markonian figured it out. Generally the reset pin is not absolutely needed, so for a quick try you could set OLED_RESET to -1, the library then will not use the reset pin.

    Extended Pin Numbering

    Sorry about that, mixed something up here - I meant brtaylors Teensy 3.6 "Pro". Good point. Suggestion for the pure analog ones?

    Extended Pin Numbering

    Found a few bugs - changed color to dark green for 72/PTA18 - added another analog input 28/0_DMO and changed numbering - added Serial6 at 137/PTD8 and 138/PTD9 - left out numbering for PTE6 - chose a darker grey for PTA4 and PTE6 As an addition for PTA4 (and PTE6), my suggestion is to leave...

    Extended Pin Numbering

    Any news here? Unfortunately I could not test this yet due to missing hardware... Two things about this approach: 1. There is a numbering failure around PTD10 2. As far as I know and according to analog.c "Pins" 70 and 71 are used for internal connections to the ADC which can read the internal...

    Extended Pin Numbering

    Should be a great job for defragster's custom design when the first prototypes are available ;-)

    Teensy 4.0 (hypothetical) pin assignments

    Correct me if I'm wrong: The outer dimension is the same (12x12mm) but it can't be pin to pin due to the 196pin BGA with 0.8mm pitch of the RT1050/-60 compared to the 144/1.0 of the K66? Or is there a package with less pins which I missed? So do I. Maybe you should put something in the image...

    [?] New Haven 128128ASC3 wiring and SPI library

    Although I really like the ILI9341 (and do in fact use ist too) there is no voodoo behind SSD1351 and it would be interesting to find out what is wrong with your setup. Might be worth it to further investigate. At the time I have just the bare SSD1351 OLED lying around, but I recently ordered...

    [?] New Haven 128128ASC3 wiring and SPI library

    Wiring looks okay so far. Did you cut the trace between VUSB and VIN on the Teensy? In this case your display has no supply voltage with your current wiring. The soldering on the pin header of the display looks a bit dirty. Have you checked if every pin has proper contact? This library seems to...

    Teensy 4.0 (hypothetical) pin assignments

    Sounds okay for me. Better implement a new function such as CANFD instead of prefering even more serial ports. Not to suppress the serial junkies :rolleyes: But please keep the second SPI if possible.

    Extended Pin Numbering

    I absolutely support this idea. Merging into the core is not really necessary, but the pure existence of a library style possibility to access all pins on custom pcbs is something I was already searching for***. In regard of the naming of these pins the port+number should be enough abstraction...

    Teensy 3.6 "Pro" Feedback

    Well, you're possibly right. I'm curious about further progress!

    Teensy Beats Shield

    This is absolutely awesome! Congratulations for your success! I watched your presentation video yesterday and I wondered about how your board has been assembled. Reading through your hackaday page brings me to the conclusion that you've done that on your own with a SMT stencil from your...

    Teensy 3.6 "Pro" Feedback

    As much as I like this approach especially for prototyping custom teensy projects which needs more pins: Do the changes since the initial idea in the first post, i.e. getting rid of the expensive extra hardware, not lead to a more or less direct Teensy 3.6 competitor?

    planning custom T3.6 - SD-Card (SDIO) and micro-USB on daughterboard?

    I already saw that, great little thing! Although it does not really change my uncertainty related to my planned USB/SD signal path. So in case my first post did not describe my thoughts clearly: How are the chances that the described signal path in post #1 will lead to a working USB connector...

    planning custom T3.6 - SD-Card (SDIO) and micro-USB on daughterboard?

    I am thinking about a custom T3.6 pcb for my product. There will be kind of a "headunit" with power supply, MCU, all needed interfacing hardware for connected sensors plus connectors for expansion modules . Further there will be a "frontend" (different frontends shall be possible, hence the...

    Extended Pin Numbering

    Recently I read a lot about custom teensy's so I think I am aware of Pauls thoughts about PTA4: https://www.pjrc.com/store/ic_mkl02.html (search for PTA4 here) Though I think about using the unused pins too in my custom design I appreciate the idea of numbering those pins...
