I don't know how your analysis tool works so I'm not sure if this will help you but 'idf.py reconfigure' also produces a compile_commands.json file in the build directory which you can use with clangd. There's also an xtensa-clang package you can install that has a clangd updated for the xtensa plat...

I just tried it and it works for me. You do only need the one "set" and it has to be after the cmake_minimum_required and before the include statement. cmake_minimum_required(VERSION 3.16) set(EXTRA_COMPONENT_DIRS "${CMAKE_CURRENT_SOURCE_DIR}/../../../components/lowlevel" "${CMAKE_CURRENT_SOURCE_DIR...

Thank you a lot gtjoseph. As you checked into the Library file, I'd like to ask some thing confused me, that are: 1. seems the ESP32 goes into two totally different branches? I have two laptops one is WIN7; and the other one is WIN10 with the Arduino core for the ESP updated. some sketches be able ...

If youi look in that library's Arduino_GFX_Library.h file you'll see #define DF_GFX_RST GFX_NOT_DEFINED It appears that DF_GFX_RST should be assigned to the GPIO that's connected to the display's RESET pin if it has one so in your code, you'll have to do something like... #undef DF_GFX_RST #define D...

DF_GFX_RST = ？

It's hard to tell because I don't know exactly what "GFX for Arduino" library you're talking about. Got a link?

3 is the screen rotation

I have to admit I cut and pasted that in a hurry from something I'd hanging around for over 20 years :) It works because the value is only used as a true/false. To be honest, it'll probably always evaluate to true even if the value is actually 0. :( So yeah, the correct code is.. int broadcast = 1; ...

Is this (setsockopt) really necessary here? In one of my projects I receive broadcast UDP packets and I did not include this line and it all worked without problems. There was only one thing I needed to change: To avoid packet loss I needed to switch from WIFI_PS_MAX_MODEM to WIFI_PS_MIN_MODEM. Nev...

Perfect, thanks!!

It's standard sockets programming. Look at the example at esp-idf/examples/protocols/sockets/udp_client. All you have to do is add the following after the call to setsockopt (sock, SOL_SOCKET, SO_RCVTIMEO, &timeout, sizeof timeout); char broadcast = '1'; setsockopt(sock, SOL_SOCKET, SO_BROADCAST, &b...
