Cross post from: Hey Teensy coders. This Monday FastLED is planning on changing the default WS2812 driver from the previous default one to Kurt Funderburg amazing ObjectFLED driver. In case you don't know, this is the spiritual successor to the OctoWS2811 driver. It was actually based off of...

Hey Paul, any insight on this issue? Looks like Audio DMA for teensy produces LED flickering on ObjectFLED: https://github.com/FastLED/FastLED/issues/1818

It turns out, the Teensy 4.1 and 4.0 are absolute LED beasts! The claim is all 50 pins can be driven with DMA. Can that be possible? The backend driver is ObjectFLED which just came out for Arduino-Teensy. FastLED 3.9.8 just made this a core driver option. #define FASTLED_USES_OBJECTFLED...

Yup, this is great. What's surprising to me is that the chargers want to bring the battery to the limit of 4.2 volts. I've gone down this rabbit hole and determined that 3.9 or 4.1 volts would be sufficient. The safety profile is better, the cycle length is better, and I don't see how a charger...

Update: I just got word that Adafruit does have undervoltage lockout on some of their LIPO pouch cells which cut off at 3.0v 150mAh: https://www.adafruit.com/product/1317 500mAh: https://www.adafruit.com/product/1578 They also said they would investigate making a product with this feature...

The problem with this approach is that many of the Arduino products have parasitic loads from the USB -> Serial connection. Might be others.

Thanks for the links. I investigated every single one and there is no mention of a battery disconnect for the low power state. My guess is that this is because they don't exist, which has been my experience. Most of the chargers on ebay/amazon suffer the same problem. But I just got some in...

There are NO Arduino solutions that charge a LIPO and have a battery disconnect during the depleted battery state. The Lilypad USB is the closest thing but the lack of undervoltage battery disconnect will result in a wrecked battery unless the user remembers to shut off the power every time they...

There are common features and there there are niche features. Power is a common feature that everyone using portable electronics must address. Conflating this with niche features like a driver motor or piezo speaker that the vast majority of users don't use, muddies the water. Wearable...

First off I want to say that I'm an avid teensy user and I love these little chips. I've been using the lilypad recently because it has an integrated Lipo charger. However they forgot to add a low power disconnect and the device will just drain the lipo until it's dead. I don't know why this...

Hi there, I posted this previous bug report. https://forum.pjrc.com/threads/68908-SK9822-LEDS-broken-on-Teensy-4-1 Now I find that 4.1 has a big problem with APA102 on platformio with the latest teensy libs installed. Like the previous forum post, the only resolution was to downgrade my unit to...

I didn't see anything in the forums related to data compression so I wanted to start a thread here. I'm trying to get a simple compression algorithm so I can store small movies (570 pixel frames) on the internal flash memory without having to move them to the SD card. Zipping up the video files...

Yup, it looks like this was the case: C:\Users\niteris\Documents\Arduino\libraries\FastLED\src/FastLED.h:14:21: note: #pragma message: FastLED version 3.004.000 Also I notice that platformio is using teensy 1.55, not 1.56-b. Any ETA on when the beta will make it to release? For a fix, do you...

I have an existing project that uses 570 SK9822 leds in one strip. Currently I'm using a Teensy 3.6 and everything works very well. I'm trying to migrate to Teensy 4.1 so I can take advantage of POV. However I've realized that Teensy 4.1, for whatever reason, has major problems with the SK9822...

USB-C connector that is through hole, so it can take some abuse with twisted wires and not pull off.
