Hey Paul, I'm waiting for a new soldering iron tip and haven't had a chance to hack the board yet. I did, however move things around a little bit for the next revision board. I moved one of the .1uf caps right next to...
Any feedback on this? I've since moved the capacitor to the area you recommended for my next rev. board, but would like to know if my ground plane design is also a potential cause for concern.
Hey Paul, my decoupling caps are right to the left of the MKL26. I'm using (https://www.digikey.com/product-detail/en/wurth-electronics-inc/885012206071/732-7989-1-ND/5454616). I have 3 .1uf and 1 2.2uf caps for...
Anyone wanna take a crack at this? I'm still pretty perplexed...from what I can gather, I should just have to connect the USB power, then ground the PTB2 for a second, and the port should show up, correct?
Hi guys. I have a custom Teensy LC implementation using your bootloader chips and am having issues getting the board to be detected via USB. Here's what I've got going on:
1. Probing the reset pin with my scope, I...
Hi Ivan, sorry for the delay. Yes, I can confirm that this code snipped DOES NOT work with the Arduino IDE using Faster optimization & Serial + Midi setting. Sounds like Platform IO is all good.
Just ran your project. Same result. What I mean by 'the program crashes' is that I don't see any serial output when using pio device monitor. I should be seeing 'looping' be spit out over and over again. If I remove the...
Ok quick update, i've ported everything over to the Arduino IDE and things work great. To be honest, I may even like this setup better. It's slightly annoying to have to tab over to Arduino and press build, but it's a...
The platform io system allows you to specify build flags which are essentially the same thing as the usb type setting in the arduino IDE. I've had a pretty complicated usb midi project build just find with serial...
Hi guys,
I'm having an issue using the Non-Blocking WS2812B library (https://www.pjrc.com/non-blocking-ws2812-led-library/) with USBMidi. Using the example code for the WS2812B basic library test, if I put...
Hi guys, I'm having flickering issues using the WS2812B LED chips.
Here's what's going on:
*This is USB powered, so I have max 400mA to work with. Keeping that in mind...*
I have 12 WS2812B LEDs connected, which...
Hi guys, I just got my first custom teensy boards in the mail and unfortunately I'm not able to get the USB device to show up. I've pushed the program button and also floated the NMI pin but don't seem to have luck. I'm...
Wow I didn't even know that was possible. I'm definitely a beginner here, but I've always thought that SMD with any real component count just needed to be done by a machine. I'm unfortunately in too deep with my first...
Hi Paul and rest of awesome smart people on this forum. This thread (https://forum.pjrc.com/threads/27397-Teensy-gt-Production?p=60903&viewfull=1#post60903), which outlines some of the design considerations for crystal...
