Note for things like this, I end up using sketcth that @defragster and I played with a long while ago:
It sets all of the pins into either INPUT_PULLUP or INPUT_PULLDOWN. You can then take a jumper wire from either GND or 3.3v depending on...
Funy you should mention it... I believe one or more of the pages has the ATP pins on them as well...
I just so happens, as I mentioned up on the thread about fancy memory :lol:
I decided to make a quick and dirty shield for the ATP board, which...
I believe that you need to update the USB descriptor to have JOYSTICK_SIZE=64, which then gives you things like:
#elif JOYSTICK_SIZE == 64
void button(unsigned int num, bool val) {
if (--num >= 128) return;
uint32_t *p =...
Sorry, I don't know how your image is created and/or stored. The sketch you mention only supports specific format bitmaps
Does your run give you additional information, like why it did not like the file?
Not sure what you are trying to do, as...
Hopefully some others might know parts of this better than I do.
If you were saying a Teensy 4.1 with one of the versions of the WW35Q64 that is supported that can be soldered to the bottom of the T4.1, I would say that you could have a littleFS...
Sometimes it helps if you show photos of your wiring.
Also additional information like, what mouse is it that you are plugging in?
For unknown devices I often use the HIDDeviceInfo sketch, as if is a normal HID mouse or the like, it should...
Probably should be part of your other thread:
You might look around the net for information on PS2...
Like: https://karooza.net/how-to-interface-a-ps2-keyboard
Looks like Paul has a library for decoding PS2 keyboards...
If you look at the T4.1 card, it is pretty easy to hook up both USB Host and USB Device.
The Device pins duplicate what is in the USB connector that you connect up to your PC.
So yes you can connect up the keyboard to the teensy using the...
Specifically regarding Arduino Giga and software, it's pretty clear Arduino has focused on developing certain features. The situation is similar with Teensy, but largely a different set of features. Depending on your perspective, it's easy to...
Different reasoning for maybe why giga on Arduino forum 😉

Meanwhiles, for anyones enjoyment, here is a video of a music player demo running on LVGL v9.0.0
I think there is a lot of room left to optimize.
It has two screen sized frame buffers (1.3Mb each) that LVGL writes into, and the eLCDIF reads from...
How do you have the backlight hooked up? Like what they show on product page
https://www.pjrc.com/store/display_ili9341_touch.htm
could up the ohm of resisto. Could hook that pin to io pin and control using pwm…
I will try to get back to trying it on this board. Sort of a PIA at times to hook up all of the wires in a secure enough way. So I much easier playing using the other boards.
Did find using my camera shifter boards I did during the T4.1...
🤔I have not seen the problem of using the 8MBtye SDRam on the GIGA for the camera to read into.
But when I looked at their schematic their SDRam setup looks very different than what I believe you are doing on these dev boards.
That is they...
Just by way of an update @KurtE got the OV7670 and OV7670 video working using the micromod as the test platform. If you try it on the SDRAM something strange is going on.
If you use DMAMEM for the framebuffers image is perfect
if you use...
Not something I want to touch.
if i were easy to do then maybe Paul would integrate it into teensyloadercli and then others could then migrate it into different apps like TyCommander
Not sure if to post here and/or on Arduino. Ran into build today that died with:
internal error in mingw32_gt_pch_use_address, at config/i386/host-mingw32.c:192: MapViewOfFileEx: Attempt to access invalid address.
Had this before, ended up...
Forget to ask/mention in previous post. When you said before each buffer write: not sure what you meant here.
That is what "Before"
if it was before your code updated the buffer to the new contents. then flushing before this would not help.
if...
For what is worth, back in T4 beta cycle, I was running into issues with the caching getting in the way.
Sometimes the cache flush and/or delete could help, other times a royal PIA...
That is why I found it sort of amusing that we used the...
@PaulStoffregen I have been playing around with the eLCDIF and a 24bit 800*480 RGB display using my experimental eLCDIF_t4 library
My first experiment was to display a static image loaded into SDRAM - that worked fine.
My next experiment was to...
Sorry, I have no idea, Could be wrong, but I don't believe that these use boards made by PJRC.
You might try asking up on some forum, geared toward the Ender 3d printers.
Again good luck
As this thread is almost 4 years old now, might help others to help you, if you described your setup:

Decided to hold off on that for now... Did lay out quick and dirty semi-shield for the Sparkfun ATP board
Slight downside is that two Teensy pnis are not available (22, 28), but...

Any time I start looking through things like, this, I end up first looking up at the USB in a Nutshell chapters

This describes many of the descriptor formats:
For example the strings at the end...
Finally got the HM01B01 camera working again with Teensy. So hooked it up to the SDRAM board using EXTMEM for the Buffer for still images. Did find that if you hook up a display best to use pins 0/1 for dc/rst if you are using 9/8 for other...
Go for it. I believe we gave links to all of the cameras you can order from Arduino, like the 7675

All you need to do is to hook up something like 16 jumper...
Keeping fingers crossed it works for you. As the tutorial you linked to shows (retired). I believe that library is no longer updated and probably had a really old version of Adafruit_gfx as part of it.
Sorry, I am sort of lost on this one. Which example sketch are you using?
If for example I try the graphicstest of the Adafruit ST7735 and ST7789 boards library, it compiles just fine for
the Teensy 4.1
As far as I can tell, the only real changes they made to their version is to add unicode support...
My fork of it with LLA support does not have that, but works fine for me so far with my HLA, which works for me to filter the data down to what...

For example with the board I am looking to maybe do. I modified it slightly this morning as I found

Looks good. Wondering about any suggestions for partially assembling a board. I have done a couple with PCBWay which has worked out OK:
But last time was about 2 years ago. With my current main MMOD test board: Where I had them do most of the...
I want to thank everybody for the advice given. I chose OSHPark. Everything worked out without any problems. I just received my 3 boards and populated one of them (barely, shakey). Hooked it up and it works:D
Thanks again for the help.
Sounds good,
I would suggest that you might make the changes and try it out. And then if appropriate create a Pull Request into core and see if/when Paul will pull it in. But still need the same stuff as we mentioned for DMA buffers aligned to...
malloc() already guarantees 8 byte alignment. It's defined this way in the C standard - any dynamically allocated memory must have alignment suitable for any native datatype e.g. 8 bytes for a double. smalloc is deficient in this regard.
And...
FWIW - I believe we should use the KISS strategy and in this case change as few system things as possible.
That is with EXTMEM or others who may use the sm_malloc code, I would probably avoid making changes to the underlying sm_malloc...
Quick update on the MicroMod board update, that I am not sure yet if I will order yet or not...

I've started working on a little eLCDIF library: https://github.com/david-res/eLCDIF_t4
It's FAR from done, FAR from something functional, but I only started a couple hours ago.
I'm not making this super fancy or super flexible - I'm making the...
Thanks, the keyword, I was missing was pass through... Found some samtec ones at Digikey.
:LOL: yep Note: 8 of them need to be contiguous for D0-7 and then two others for Pin clock and HSYNC
I too, except - Except would be nice, to have some...
On the GIGA board they show it in the schematic like:
So far did not find anything 21TW-247 They show the same on the GIGA Display shield.
On their interactive display of the board, they show it as:
I know I have seen similar type connections...
I am sort of torn on a lot of this stuff. That is I like what you are trying to do. But I would be far more interested if for example Paul was building a Teensy 4.x with these features. Then I would be all in.
For example should the camera...
Great success!
Swapped the color order on the pins, so its wired B0-7, G0-7, R0-7 on LCD_DATA0 through LCD_DATA23 pins and it looks great!
So that confirms the color order on the eLCDIF output is BGR and not RGB
Here's a quick update from me:
Got some 5" and 4.3" LCDs here, 800*480px, 16.7M colors
@Dogbone06 sent over some Adaftuit 40 pin lcd breakout boards which arrived on Monday, got to wiring it up day before last, and started testing.
Consulted...
