    Currently @mjs513 and myself have setup to use the cameras which have the Arduino GIGA like pinouts: Which include the OV7670 and OV7675, HM01B0, HM0360 and the 2mb GC2145. You can see details and purchase them from Arduino...

    Probably the simplest way is to modify the table: https://github.com/PaulStoffregen/USBHost_t36/blob/master/joystick.cpp#L58-L77 And do a Pull request to this github project.

    As you know @KurtE and I have been making a few more mods to the PXP library which seem to resolve a couple of other issues we came across with further testing. Including fixing decimation which has now been tested down to a scale factor of 10...

    I updated the excel document to match the update... probably more of the usages of the pins can and should be double checked... No objections from me... Note: I could probably never run out of things to ask for, but ... I believe you have host...

    I took the easy route. I usually put pin numbers as defines and name them. So I'm ready to order if no one has any objections?
  • KurtE
    Two options: a) Easy - make them the next two pin numbers so 68, 69 b) slight more work - make them 64, 65, and update the current 64... numbers on that side to +2 so 66, 67... Either works for me

    I can share all the files if you want. That's the plan anyway. But here's some real measurements. * Left to Right * Right-Top to Right-Bottom Look at the "Length" on each of the two.
  • KurtE
    Assuming you go with this layout, do you have some measurements, like deltaY between the two rows of pins and maybe where the power connector is located? in case some of us might be tempted to layout a Quick and Dirty shield or two. Thanks Kurt

    These are made by Bakon (https://www.bakon.cc/) in China, a pretty high quality company. I've bought several directly from them, truly works a charm and the tips they provide are the best I've tried. Lots of solder tips out there are garbage. So...

    I'm done, unless something is wrong. Please look it over. Fat lady became thin lady:
  • KurtE
    I think you are close, the only things are: You showed 32 and 32 on right hand side above... Note: this has slight numbering issue in that we don't have a 46 now. But no biggy, I will leave it as duplicate of 32... Or could mark it bad...

  • KurtE
    Different Teensy boards have different logical mappings from their Arduino Pin numbers to the actual IMXRT Port/Pin number. In this case B0_12 On T4.1 we see: So it is pin 32. And you are right it is also pin 32 on MMOD: 32 65 B0_12 2.12...

    B0_13 should not be marked pin 25, that would be AD_B0_13 (if it was routed). So B0_13 is another without a number. @KurtE B0_12 is pin 32 on the micromod, not sure why your spreadsheet gives it a new number and says 32 is for T4.1 only?

    Almost done. But there are quite a few pins that I don't know the pin number for. What to do here, can someone list those?
  • KurtE
    Sorry, I will update to your new picture, I did a quick and dirty update to the spreadsheet. It is not done, as you can see the pins don't match on the right hand side, as you moved up some pins to replace the first GND to move the one pin into...

    It's fine mate! I'm also cutting 12mm length of the board, to the right. It will not affect the current layout at all. I am just shortening it as there is space.

    KurtE reacted to Dogbone06's post in the thread Call to arms | Teensy + SDRAM = true with Like Like.
    I mean the actual numbers, on the outer edge of the headers. Right now that's empty. Except for bottom-left which has "5V" and "GND". KurtE wanted pin numbers there. But the names you talk about, that should also get an overhaul I believe. So...

    Probably a good idea. Oh - if you have enough room then definitely, and then you don't have to change what you already have on the inside of the headers. Sorry still early for me

    Sorry got distracted by the pictures. Think if its available I would add the pins numbers instead - lot easier. For instance for SPI would be easier if you should 11, 12, 13 instead of B0-00, 01, 02, if I remember right

    Good news, the 6 pins are routed. It's not pretty, but it's routed atleast. That little 10x10 BGA is about as crowded as China! So last thing to do is add the pin numbers on the outer side of the headers. Should I add the actual software pin...

    SoftwareSerial - I am pretty sure on T4.x it detects if the pins passed in are HardwareSerial pins and if so uses the HardwareSerial code, with some added overhead: size_t SoftwareSerial::write(uint8_t b) { elapsedMicros elapsed; uint32_t...

    If that's the only purpose for counting the pulses, you're better off using one of the timer modules that can generate a single interrupt when the total is reached rather than 5 million individual interrupts.
  • KurtE
    Getting too old to solder and resolder those small parts. Easier just to order one already set up :)
  • KurtE
    So you decided not to unsolder something like 9 (19, R21-28) resistors and one jumper(3), plus then solder one resistor(20) and one jumper(6) Ditto... I have not ordered a new one yet, although I do have the one from Amazon also arriving tomorrow.

    I am assuming that that it was voted down. I am also assuming that this vote was for double row with different signals. And not, double rows like the Sparkfun Micromod boards like: Where they have two connections per signal.
