Sorry Brian - all I can say is that I have been using a couple of the early batch on and off with out issue - must have got luck. Never tried running for more than an hour or so.

Impressive project! Hope the PCB is working out for you. Paul

Yes, that's my hope... especially coding time! I'm not ready to think about any new products until Sparkfun has been shipping Teensy 4.0 and Teensy 4.1 for a while. We've been pouring a lot of work into this transition for the last few months...

Do tell ... ???

Indeed, Sparkfun has done well with MicroMod PJRC developed with them and SFun has been good to order from for years. Will be nice for PJRC to get to focus on things other than parts ordering, building and shipping.

This makes a lot of sense. A trusted partner who deals with supply and manufacturing means more focus on the all-important software and support side (which is the key differentiator from random Arm MCU boards that utterly lack a solid software...

Congrats! I wondered when something like this would happen. Makes a lot of sense, since they already are making the MicroMod. Should leave you with some coding time, and potentially new products.

Wow, sound like a great move for you and Robin. I look forward to you being able to spend more time on moving the software side. Best of luck.

Not sure whether to be sad or not but know it will take a heck of lot of pressure/stress off you and Robin having to deal with supplier and manufacturing issues. Definitely should free up a lot of time etc. So going to say congratulations and...

We are excited to announce the expansion of our partnership with SparkFun Electronics to include the manufacturing of all Teensy products. Teensy 4.0, Teensy 4.1 and related accessories will now be manufactured by SparkFun in Colorado, USA...

Hello, I have recently started a thread about a similar project. I start a new thread because I have completely re-designed my Theremin. I have minimised the number of components to make it easy to build on a simple strip board. The code is...

Frank, if you look at file cores\Teensy4\CrashReport.cpp, you will find the code shown below, which reads and interprets the bits of register SRC_SRSR. Bits 0-8 indicate the cause of reset. You can copy and modify this code for your own use. The...

You might also try telling the display to invert the colors, like: tft1.invertDisplay(true); As defined in the Adafruit_SPiTFT file: // ------------------------------------------------------------------------- // Miscellaneous class member...

There is also a ST7735_t3 library that is bundled with Teensyduino, it supports the ST7735 and the ST7789. There are multiple examples to show how to setup. For example, for a 240x240 display the initialization is simply // For 1.54" TFT with...

Just ran a quick test using itoa() and utoa() and seems to be working at least on a Teensy 4: char numberArray[20]; uint32_t number = 35000; // 5 digits #define volumesize void setup() { while(!Serial && millis() < 5000){}...

You might try starting off, running one of the SDFat test sketches from the Adafruit branch, to see if they work at all on the T4. I have not used this fork of the SDFat library on Teensy boards, I have used it on a few of the Arduino boards. I...

@JulienS: So, you would probably be safe to conclude that the Teensy is not UL certified. A quick Google search reveals that UL certification is reported as being very expensive. I am certainly not intending to speak in any way that might be...

Before, I try to answer these, I thought maybe should step back a second and give a little more background information. Half Duplex: The Dynamixels use half duplex Serial to communicate. That is that there is only one data wire between them...

Not sure if that sort of debouncing would help for your frequencies?

This is my favourite approach (parts 1 & 2): https://hackaday.com/2015/12/09/embed-with-elliot-debounce-your-noisy-buttons-part-i/ https://hackaday.com/2015/12/10/embed-with-elliot-debounce-your-noisy-buttons-part-ii/
