That IS nice. Another thing I noticed there is that they added a couple of voltage dividers connected to both USB VBUS and VSYS and connected them to a spare analog inputs to add voltmeters to both power supply...

Can you post a picture of the tearing on the display? Could be a configuration issue...

Same, 4 wire SPI.

Not sure how the age of the ESP8266 is an issue for you, but they are quite simple to use and cheap and plentiful. They don't have BLE5, though. Both the ESP32 and ESP8266 can be put into low power mode, though that...

Looking at the schematic, it's surprising that the MicroMod Reset pin is connected to the Teensy On/Off and not a reset as per the MicroMod spec.

Might be better off using a FET and a NO tact switch. It would probably be cheaper too.

Or a modified boot loader chip that uses a double tap or long press on the program button to do a reset.

Alas, no, there is no reset pin available on the Teensy 4.0 or 4.1. It is possible to do a software reset, but that won't help in the case of a firmware fault.

My interest in M.2 was as a cheap, higher density connector and not for mPCIe connectivity. For the Vidor it kind of makes sense given the FPGA on board. The applications that make sense to me for a Teensy with mPCIe...

One way to expand the number of pins available would be to provide double-density castellations along the edge. The Alorium Evo M51 does this. Every 0.1" spaced through-hole pin is brought out to a castellation at the...

I'm able to trigger the "2D ready failed" with a low voltage on the 5v rail. Could that be an issue for you?

NM, found it. (Wasn't searching in the right folder...) Apparently the 8876 isn't responding. Not sure why that might be intermittent on my side, but if it happens fo you from the start, Keith, it implies a...

Interestingly, I'm seeing "2D ready failed" on my console too. It's happened twice now after running some demos for a long time. Not sure where it's coming from, searching the source comes up empty. And it...

Yup, I"m on 1.53, though I'm using Platformio. Shouldn't matter. And the board is v1.0 Here are images of my board and wiring for a sanity check: Hard to trace out the wires from those, I think. Happy to...

Is it possible for you to test with the ER-TFT0784.ino example? I just verified that with hardware setup the same as is in there, that sketch works.

Same here. I did have one display that came from BuyDisplay that was misconfigured. Couldn't hurt to double-check the jumpers per the datasheet.

Sorry for the silence. 2828DC / Pin 36 doesn't need to be connected. Not sure what the error "2D ready failed" is... One thing to double check is that the display is getting enough power. My T4.1 & display...

That IS strange. Can you share your platformio.ini contents and confirm that the only change you are making to the contents of framework-arduinoteensy is to replace the cores and libraries directories with symlinks?

I believe that the version number it's displaying is obtained from .platformio/packages/framework-arduinoteensy/.piopm which hasn't changed, but you've replaced the code in the cores directory, so it should be...

There's an early bit of development being done for RP2040 support on Platform.io. I was able to do a basic blink application using the Arduino framework with it. Might be worth looking at and/or pitching in: ...

I ported over a bit-banged version of configuration code for the SSD2828 and added it to my fork of the Ra8876LiteTeensy library. You can see the files here: ...
