Re: Arguments for automatic build

Try making a change to a value in the sdkconfig file located in your project directory and performing a simple make. In my experience, this causes it to be parsed are rebuild sdkconfig.h.

Re: Arguments for automatic build

My understanding is that the "make menuconfig" tool is merely a very nice editor for editing the file called "sdkconfig". If you open that file with an editor you will see it is nothing but name=value pairs. In your build system, you could use a string processing tool like awk or...

Re: Integrate BootWiFi snippet in IDF C project

From a C program, there is no way to create a C++ class and call it. If you want your "main" app to be pure C, then you would create another C++ source file and expose a function that can be called from C and call it such that it calls C++. For example. File: mycpp.cpp extern "C"...

Re: c++ and simple wifi example

In your C code you have the following: // wifi_config_t wifi_config = { // .ap = { // .ssid = EXAMPLE_ESP_WIFI_SSID, // .ssid_len = strlen(EXAMPLE_ESP_WIFI_SSID), // .password = EXAMPLE_ESP_WIFI_PASS, // .max_connection = EXAMPLE_MAX_STA_CONN, // .authmode = WIFI_AUTH_WPA_WPA2_PSK // }, // }; while ...

Re: Eclipse: fatal error: ets_sys.h: No such file or directory

Are you sure you are trying to compile the correct thing? In your log I see:

C:/Espressif/examples/ESP8266/blinky/Default'

This is the forum for the ESP32 ... are you perhaps trying to compile an ESP8266 application? Those are different than for applications for the ESP32.

Re: c++ and simple wifi example

Howdy, My suggestions would be to take your C++ application to the most minimum version that performs the function and fails and post a link to the source so that we can take a look. Switch on verbose trace and include a link to the output as well. The net of what I read in your post was: I have a C...

Re: Seeing ESP-IDF source codes in my eclipse project

Howdy and welcome to the forum. The answer to your question is "yes". Eclipse is super powerful but with power comes a LOT of complexity and features. For example, the ESP-IDF is distributed in source form. This means that the source files for ESP-IDF are available to you. Find where you d...

Re: Default state of MOSI

Howdy, I'm afraid I don't understand (and its likely my problem). I have always assumed that an SPI slave ignored the incoming MOSI signal until its Chip Select (CS) was driven high and the clock pulse said "read MOSI". Until both of those are true, it shouldn't matter what signal appears ...

Re: line in audio send over wifi possible?

At the highest level, it feels like you have a puzzle in two halves. The first part is receiving an analog signal and encoding that as a digital stream (your incoming signal) and then a second part which is taking a digital stream and turning that back into analog output or PCM output signal. The si...

Re: ESP32 DevKitC Debugging

I checked my Eclipse Oxygen and the C/C++ GDB Hardware Debugging module is part of the Eclipse C Development Tools (CDT). See the following: https://www.eclipse.org/cdt/ Make sure that you have the C development tools package installed in your Eclipse. This is installable from Help > Install New Sof...
