Re: why does malloc not give memory that is available?

Turns out I had to print 8bit memory, I forgot about that. Heap/32-bit Memory Available: 139756 bytes total, 82808 bytes largest free block 8-bit/DMA Memory Available : 56804 bytes total, 43520 bytes largest free block Malloc LEDMatrix Failed. Bytes requested: 49152 So, this explains that. Sad that ...

Re: what is the difference between compiling for esp32dev vs nodemcu-32S?

Thanks for confirming, it seems that esp32dev is the best option then, especially now that I added a bunch of partitioning mappings in master, including ffat partitioning options I use :)

Announce: SmartMatrix::GFX for RGB Panels and running FastLED/NeoMatrix code on top of RGBPanels

I spent quite a bit of time hacking on my new party shirt (since last year), which is now based on higher density RGB Panels, which however are totally different technology compared to my previous NeoMatrix shirt. I ended up writing SmartMatrix::GFX, a glue driver to allow all my previous code to wo...

Re: Has anyone made an RMT IR Receive library for ESP32/arduino?

I was pointed to https://github.com/lbernstone/IR32 and was able to use it.
It has some small unreliabilities I'm still working with, but overall it works.

Thanks for sharing. I think Infrared is 38Khz, but I'll see if your code can be made to used anyway.

Has anyone made an RMT IR Receive library for ESP32/arduino?

I know about this library, https://github.com/z3t0/Arduino-IRremote , I contributed the ESP32 support for it 2 years ago. That being said, that library is all interrupt driven and the ESP32 support I added doesn't make use of RMT, which would be a pretty complex change in that library. Has anyone wr...

Re: what is the difference between compiling for esp32dev vs nodemcu-32S?

So, no one can tell me why there are so many ESP32 chip options I can compile for, and why compiling for ESP32 dev seems better options-wise than using NODEMCU which is the chip I actually have?

Re: How do I debug out of RAM conditions (SmartMatrix + AnimatedGifs + other) on ESP32

ESP_Sprite, thanks for your answer. First, I have 6 posts now, so it's taking quite a while for the anti spam to go away. Sadly, my recollection of this group is that every time I took the time to post here, it took over a day (hours/overnight would have been understandable) to get approved, and by ...
