Just for any who cares. The difference in toggling the IO in my example with CPU @ 240MHZ is 3.6MHZ, and when CPU is set to 160MHZ its 1.8MHZ

I have no way to change what they are doing. I wore just looking to see if "-DF_CPU=" was documented as a parameter to pass to the compiler, or it it changed to something else and its now outdated what they are using.

Is there a flag option "-DF_CPU=" that changes the CPU MHZ ? I am having an issue using platformIO where their setting for changing the CPU MHZ is not taking affect. At compile time they add this flag option "-DF_CPU=160000000L". Regardless if it's 160000000L or 240000000L does not affect the CPU sp...

Move the while (1) { just above err = listen(listen_sock, 1); and comment out the 2 break statements above, youll have to deal with the break logic better, I just didn't have the time. But this makes it work. You dont want to bind again, once you have already bound. Looks like this. static void tcp_...

I'm not an expert (professional) PCB designer

I am, and have been one for more than 25 years. In looking at loboris PCB he did a dam good job. He may not claim to be an expert, but you can tell he understands things in how to do it.

Well, when you have made a decision let us know.

What would you like to know about it?
The best thing to do is try it yourself.

Thanks for sharing!!!
This is exactly what I have wanted to do for a while now. So glad you posted it.

PS. Dave, you share the code source for that project, and get into the hardware side of it too ?

You are aware thay ESP-IDF and Arduino can be used interchangably? You can use ESP-IDF code in the Arduino environment; you can also drop the Arduino component into ESP-IDF and use the Arduino API there.

Get out!!! I had no idea of this, I have to give that a go.

Opera has a really good debugger. I just starting using it and I like it better.
