FYI I was using this Molex FFC FPC connector https://www.digikey.de/product-detail/de/molex/0522070833/WM10376CT-ND/4505929 (I bended the pins to fit the 1.1 mm pitch of the uSD) A flat USB cable was easily operated...

<placeholder> for second beta 1062 board - linked in OP Teensy 4.0 First Beta Test KurtE posted XLS pinout for Beta2 w/1062 {update here} Issues:

Perhaps a post about here somewhere - with a link in OP to "Teensy 4.0 SECOND Beta Test with 1062" for initial links to the flurry of stuff that will happen in coming days? I'll start that after this post with a link to...

Nope. I have some special plans for debug features on T4 in the future. Not ready to discuss at this time. Yeah, I sure do know about that lack of time issue...

I can only help if your using all PJRC hardware. I need some more information to work with here. Are you using all PJRC hardware? What Teensy are you trying to use? (I used a Teensy 3.2, not sure this will work...

@PaulStoffregen Will there be debug pads/pins available on the T4? On another note, I still need to make my Teensy3 JTAG programmer do SWD. :-) I plan on releasing it on GitHub at some point, perhaps highlight it as...

Few hiccups, and step forward with using Sony Move Navigation controllers: Modified joystick.cpp: From: { 0x054C, 0x0268, PS3, true }, To: { 0x054C, 0x0268, PS3, true }, { 0x054C, 0x042F, PS3, true }, {...

Please keep using this thread. Really helps me later if everything was all in the same place. When the boards are in production, I am going to spend a few all-nighters going through most of the messages.

Not that I mind testing but with the 1062 coming next week and 1052 going to be phased out is worth the effort - besides not sure how to get to the underside pins :)

Sounds good. Note: we could also make SPI1/SPI2 on beta 1 as well as these are the same IO pins.... But not sure how much time we will take to test it on B1 boards. @Paul - Wonder if we need a new thread? This one...

Have you investigated whether the Teensy already has what you want? Perhaps there isn't an Arduino method to do what you want, but you do have access to the raw machine. In terms of relays, you can either kit up the...

Just pushed change that should add support for SPI1 and SPI2 for IMRTX1062 to the ILI9488_t3 master lib.

@KurtE You going to use the same constructs for IMRTX1062 SPI1 and SPI2 as for the 3.5/3.6. If you are I will do the updates for ILI9488. BTW> The spreadsheet comes in handy. I have it in a word document now and...

Quick update, I updated the zip file in posting #2269 with some fixes to IO pin numbers for last two, plus XBar information, plus some other fixes...

Hi Paul, no problem. Exciting! Can't wait for T4 :D In the mean time, here is my fork and the anti-alias-font branch. Hi KurtE, I'll add support for BDF2.3 (anti-aliased) fonts to your version of the lib today :)

FYI - I just pushed an update to my more core files that did my a1) from earlier posting. I believe the order of SD pins as given in earlier posting about the positions of the pins on the bottom of board. I went in...

Note: Still working on it. On the Beta 2 page I have logically added the SD Card pins as Pins... I have not done that yet in code. Nor finished all of the things these pins can do, like the PWM pins.. Or XBar...

@KurtE Just downloaded updated core files. The only I can say right now before company gets here is that for B1 board graphicstest9488 still compiles and runs. It also compiles with no issues for the B2 board. ...

Sure that would be useful.

For what it is worth, I have started hacking up a version of Core for Beta 2 board: I put up the initial changes for Pins 5-8, 30,31, 33 I also made the changes in Serial2 for which pins to use for TX, RX Plus made...

@KurtE read my mine about trying out the ILI9488 library with the new board so that is probably the fist thing I am going to check. After that I will check the on/off switch and see what will happen in different...

I've just tried this and I can get the audio board and octo board to work independently but not together. I have duplicated the octo board pins as shown in the photo above but I get nothing on the strip. The only...

My biggest concern for testing is the powerdown circuitry. On the 1052 betas, the 3.3V power was always on. With this new board, the 3.3V regulator can be completely turned off. Power remains applied to the USB...

Looks like mine should arrive tomorrow as well. @Paul - let us know if there are things that you wish to test out and/or update soon... My thoughts are, to: a) Update the pin table - starting probably in...

In the mean time, for the fun of it, you might try integrating it with my version (github.com/kurte/ili9341_t3n) :D Note the code in my version is a bit different as it also works with Frame buffer support, plus some...

Please remind me of this a few weeks after we start shipping Teensy 4.0. Until then, I'm probably not going to merge most pull requests. Sorry, I'm just one guy and T4 is already *way* behind schedule!

Thanks for the advice, I will look into getting my own boards manufactured :)

Hi Michael, Thank you for your detailed reply. I will examine all the links and get back to you after a good read. :)

Hi Paul, I added my support for anti-aliased fonts to the ILI9341_t3 library. It simply uses the textbgcolor to work out "anti-aliased" pixel values (so doesn't read from the display first). The code branches within...

Good info Paul. My starting point would have failed given C tracks the registers in use without the explicit ASM clobber list showing in the .lst output file.

The other thing you'll see in that guide is register macros. For ASM code that integrates well with surrounding C & C++, the idea is to let the compiler choose which registers your ASM code will actually use. If you...

It fails because you're clobbering registers, but you're not telling the compiler. If the surrounding code depends on those registers, as is the case when you omit the Serial.print call, then you'll almost certainly...

My starting point would be :: Write the equivalent loop() code in "C" first and see that work - then perhaps again visit the .lst file to see what is different. That is write in C only what you want the ASM code to...

Didn't know that I could access the .ASM, nice! So I don't know assembler, and don't really know whats going on... Intuition tells me that without the Serial.println that the compiler optimizes something out of loop...

It really depends on what you want to do (and what Teensy you have), and what your soldering skills are. I go back and forth of how to mount stuff on Teensys, so perhaps I am not the best person to answer. It...

I'm unable to use the phoenix configurator, when I open it up theres no information in the COM box and nothing seems to do anything. Is there some special way its meant to run?

I'm exploring this suggestion today, since there's really no clean way to solder a SD socket directly to the board. The orientation we had on the beta #1 boards would have required a SD card to hang well into the space...

Paul, What memory does your delay class use? I thought about trying to edit that since the sample time is long enough for what I am trying to do and it does not require external hardware. Thanks

I saw a difference with extremely slow speeds / acceleration rates, and you also mentioned the "ugly asymmetry". I thought that was gone with my suggestion...? Thanks a lot, this is a very good solution!!! Happy...

That’s a great suggestion! I also wonder if triggering the serial print after a serial read value would help in their situation.

@KurtE Figured you wanted access to SPIclass but never in a million years would I have figured out that was what was going on. Going to have to absorb this now :)

Nope, I only make the boards for own fun... However I do typically put files up on github, like in the project: https://github.com/KurtE/Teensy3.1-Breakout-Boards Most of them have diptrace design files up there are...

It is a really bad hack! I wanted access to the internals of the SPI class. And for example the KINETISK version starts off the data associated with it, defined like: private: KINETISK_SPI_t & port() { return...

1st please accept my sadness on your countries Lunar Lander failure - so far so near. :-( The failure type I have found seems to be endemic to the Arduino ecology - pity. I do understand the problems both caused and...

@KurtE Was going back through the SPI changes you made to test for the spi port. Can you explain to me what the heck these lines are doing: uint32_t *pa = (uint32_t*)((void*)spi_port); _spi_hardware =...

The Brilliance comes from FrankB ... I just remember how to enable it :)

@KurtE Good idea. The new thing will probably have some differences we have to address anyway.

Brilliant. Thanks.

In your TeensyDuino installed boards.txt there are two commented lines. Close the IDE - edit these two lines and open and there will be a new menu option for speed: teensy36.menu.speed.256=256 MHz (overclock)...

On my last ideas - I think I will punt for now... Example with Fonts, the number of pixels to output at at time in one color is pretty small, so did not help Also checking for pixels same color did not help... ...

@KurtE - @defragster PR Processed with the changess

I believe you also sent me an email message, right?

Hi Paul, I configured the CPU speed at 8 MHz of my Teensy 3.1 and now it doesn't work more, what I can do to revive it?

I am seeing a bunch of speed improvements - maybe not as much as the TLC but still a bit of a change. Whenever you want to do the PR that's fine. Now I have to change the comments that the lib supports the TLC as...

Ok so you are within the 8 that the octo library uses. Study how it works. More specifically the artnet example. Look for the part where data is inserted into the array. I would be creative with your loop code and...

The sequence of overriding acceleration and speed should be irrelevant (at least this was the intention) I tried your change but I didn't observe any change. Anyway, I see what you want. The current code uses the...
