It is better to bring up CircuitPython issues in Adafruit spaces. We don't monitor this regularly. Thanks. Please open bug issues like these in https://github.com/adafruit/circuitpython. This particular issue might be covered already in https://github.com/adafruit/circuitpython/issues/4841.

There is a download for 7.0.0-rc.2 on that page, on the lower right-hand side (or scroll down if you are on a narrow screen). I have not had a chance to test this myself. Could you bring this discussion to https://forums.adafruit.com/viewtopic.php?f=60 instead? Our support people read that.

The BNO055 board has its own pullups. So when it's not wired to the Teensy, you should see about 3.3V on the SCL and SDA pins on the breakout. You have 3V from the Teensy going to VIN on the breakout, I think, but it's a little hard to see from the picture. What version of CircuitPython are you...

These are the pin definitions for the default board.I2C() in CircuitPython: SDA: GPIO_AD_B1_01 SCL: GPIO_AD_B1_00 It looks like those are the pins you selected, but double check. Did you measure the voltage at those pins to see if the pull-ups are working and the wiring is OK? If you ask in...

If I set a USB Type in the Tools menu in Teensyduino, what is being done behind the scenes? From https://www.pjrc.com/teensy/td_mouse.html: I'm not sure exactly what this means. Is this compile-time or runtime? Is extra hidden code added to the final C++ file to support that particular USB...

There was a bug introduced in 1.8.0, fixed has been proposed: https://github.com/arduino/Arduino/pull/5756. EDIT: OK, now I see Paul actually reported the fix on the arduino.cc forum.

Are you sure the tip and ring of the plug are shorting when inserted? In many of the 3.5mm jacks I'm familiar with, the tip (point) of the jack does not touch its contact until it's past the sleeve that contacts the ring. There are some jacks that short the connections when nothing is plugged...

Adafruit sells a video wall controller which will drive Neopixel panels: https://www.adafruit.com/products/1453 ($300). It looks like a PCIe card but doesn't actually need to be plugged in. It takes DVI video as input. Here's a tutorial: https://learn.adafruit.com/adafruit-diy-led-video-wall. I...

I'm not sure if this is your issue, but one problem that's been noticed several times with the Feather radio boards is that the receiver sends the acknowledgement message too quickly, before the transmitter has a chance to change back from transmit to receive mode. If you insert at least a 10...

I think it was just today Limor was notified of and realized the VBAT bug. As for out-of-stock, Adafruit seems to typically make a small run when they first introduce a product. They gauge future demand based on how fast it sells out, and also have a chance to fix bugs in the next batch. They've...

Adafruit has now posted the EagleCAD PCB files of the Teensy Feather adapter to Github, along with a Fritzing version (which they now generate automatically): https://www.adafruit.com/products/3200#technical-details-anchor

I asked Adafruit to post the board files to Github as they usually do.

@int13: I am the original poster. I was expressing my confusion at finding a website that included a lot of obsolete information on its front page and the major pages that linked from it. I made some very specific suggestions about some minor tweaks that I thought would make it clear what the...

I agree about wishing for USPS from Adafruit, but they say they've had much more trouble with it than UPS. They do allow USPS to certain areas; I'm not sure what their criteria are. I try to order from Adafruit on Wednesdays. They give a 10% off coupon code on the Wearable Wednesdays and Ask an...

I also shop at YDI and the Cambridge Micro Center; I've gotten a Teensy from each. I have spent half an hour trying to find something in the parts department. There's an amazing quantity of goodies there. I have scanned all the hooks and now have a general idea of their categorization system. As...

I got interested in microcontrollers a few months ago, and found out about the various Teensys. But when I visited pjrc.com, I wasn't sure whether it was still in business or not. It was only when I clicked through to the Teensy links and found forum.pjrc.com that I realized there was a thriving...
