Am I the only one who feels like they have to unplug USB ports and double tweezer the reset pins over and over again just to program this chip? I’m using the arduino IDE and it seems like different variants of my code seem more or less likely to cause the serial port to reject the device, but the pa…

Hi there, I like this one for Neopixels (sunglasses required ) :grin: [MG24 and NeoPixels (ring)] As You were :saluting_face: GL :slight_smile: PJ :v:

Yeah, I just picked up the nRF52840 Plus and already regret not getting the Sense instead. I need to do better research before I buy. Anyhow, thank you both for the knowledge and wisdom. Have a great day!

You need to start your own Highlighted Projects Thread… for archival and retreaval purposes

On the topic of dynamic memory allocation, I’m about to try and run a tensorflow model on the nRF52840 and I see their codebase also has a few mallocs in it. While I assume that the authors have thought about this, as they’ve written documents such as this with phrases like “no dynamic memory alloca…

Hi there, SO , Check out a couple posts on it. You hit it right though. You use seeed Schmea file to handle it. Train the model , build the data set, then deploy to the device. The Grove AI II is one. I have a demo on her of it and the process. HTH GL :slight_smile: PJ :v: FYI, Rumor …

I started trying the nRF52840 today and it seems like I’ve bricked it on the first couple uploads. I see that there’s a procedure for resetting them or whatever, but I don’t want to buy extra hardware and I don’t want to figure out extra software. I already regret the money I’ve spent on these thing…

Hi there, SO , the Double reset FAST pressing it will drop it into Bootloader mode and the comm port may change , reconnect and flash with the blinky program, Read or follow the WiKI on this device it is ROCK solid and only catch are there is two different BSP (board support files) those are provid…

PJ, I can’t tell you how badly I just want to blink some LEDs :rofl: I just also need a small form factor (and possibly also to run some gesture recognition in TF). I’ll try this again when I cool down probably, but I’m looking into other solutions that are more forgiving. If you have anything nice…

It might be the same as the XIAO ESP32-S3, but I haven’t tried that one either (I’ve been suffering through the SAMD21 and nRF52 ones). Can you comment on whether I’m likely to have the same corruption/bricking issues with the ESP32-S3? On a different forum, I was recommended the RP2040 chips becau…

This is a tool I created when I ran into trouble after losing the SAMD21 bootloader. I’m not sure if it matches your current problem exactly, but I think it might be helpful.
