SDK v3

I noted when switching to the current v3 SDK: - user_rf_pre_init is NO LONGER called (contrary what is said above). You can set a variable in your function and check it later to see. - user_rf_cal_sector_set is NO LONGER called (contrary what is said above). You can set a variable in your function a...

Re: Stack pointer area?

Re: Stack pointer area?

I am sharing my experiences about this here. I really hope some of the Espressif employees will step in and comment. Otherwise it may serve as starting point for others that have the same question. BTW this is all non-OS SDK. To start with, during the very early boot process, some functions in user ...

Re: Stack pointer area?

Totally understood ;) I already guessed that would be the way to go if nobody could give me this information (either because unknown or because classified (for some stupid reason)). I'd simply allocate some growing array on the stack though, rather than having a function recurse on itself. Issue is ...

Re: NONOS 2.0.0 to 2.1.0

If you make any delay long enough, wifi will break anyway. I don't think you should use them, use timers instead.

Re: Stack pointer area?

Hi Pratik, Good to see you're still around here ;) You say this: The DRAM is actually 96kB. With nonOS SDK, the remaining 16kB gets used for ROM code. In RTOS SDK, you have the entire 96kB for data, bss, rodata and heap. Because heap is the flexible one here, it depends on the size of (data+bss+roda...

Re: ESP8622 programmer using ESP8266

The link doesn't give much information. Is this an USB-serial converter (like CP2102) and some connectors added?

What ESP's can fit out of the box? I need ESP01 and ESP201.
