FreeRTOS alternatives
I just noticed a wide variety of real-time operating systems out there. Here is wiki list: https://en.wikipedia.org/wiki/Comparison_of_real-time_operating_systems When I visited a couple of websites - the features of those were very impressive I wonder if there is some better faster alternative and ...

Re: ESP32 and flight controllers for drones
Sounds like OS has very limited operations. Maybe a different lightweight OS should be used. FPU low performance is probably related to how the compiler optimizes the fpu code. LX6 is a 5 or 7 stage pipeline RISC - e.g. for best calculations it needs very good instruction pairing and alignment. If i...

Re: ESP32 and flight controllers for drones
Of course this all is worth investing. I would try to overclock a bit the CPU. Not sure what is the nominal value but specs say it can go up to 240MHz. Also as it comes to cores - try doing opposite thing with cores. Put criticals on 0 and network stuff on 1. You want fast calculations to be disatta...

Re: ESP32 and flight controllers for drones
I am developing a flight controller for quadcopters but it is still long way to go. Acro mode works fine, in stab mode quad keeps drifting to one side. You can check it out at https://github.com/michprev/flyhero-esp32 That is awesome. Have you tried rev-eng. Betaflight or Butterflight open source F...

Re: ESP32 and flight controllers for drones
Well mostly it is the 2-core feature, hardware SPIs/I2Cs, higher clock speed, higher DMPS (600). The mystery is power consumption but we are talking about miliamps here.BuddyCasino wrote:Can you expand?Deouss wrote:but they are not so great comparing to ESP32

ESP32 and flight controllers for drones
This is maybe a question that is very wide but I see that many drones have STM32 (F3-F4 ARM) MCUs but they are not so great comparing to ESP32. So I am just curious if there is any drone that has ESP32 flight controller or any project/kikstart to do that... It would be nice to see how esp performs w...

Re: C# SDK
C# SDK Is it still possible to get some example code for C# ? I tried my best to wrap the API from the SDK into C# but there is no real success. Thank you! I was also interested in that. But it would be better to just port this library into C++ under VS via either extension just like vsmicro or som...

What is the best environment to work with ESP32 projects
Is there any recommended and specific platforms that are best suited for ESP32 development? I am talking about OS and IDE together. I see it is possible to build C++ projects with Eclipse which is super nice. Work in Ubuntu VM under Windows or just install Eclipse under Windows and use that maybe? W...
