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...

Re: OTA via ESP32 to STM32 with CAN

From what I am hearing, it sounds like you want to receive your STM32 images over the WiFi network owned by the ESP32 and then stream that over the CAN bus to the STM32s. This would mean using some networking protocol logic on the ESP32 to either pull a new image or listen for pushes of a new image ...

Re: uart flow control issue

Could it be that you have to write your own buffer in which to store the incoming bytes being received from serial? For example, performing a uart_read_bytes() may receive the bytes that are currently coming in until the maximum is received. But it may be that if you are not actively reading bytes t...

Re: mingw32 stop working after ESP-IDF update

I am extremely green on working on ESP32 in Windows but I had a similar problem. As I hunted google, I found a recipe that resolved my instance. 1. Go to where msys32 is installed. On my system it was C:\msys32. 2. Run "autorebase" script/batch file found there. 3. Reboot your Windows PC. ...

Re: truncate a file

If it were me, I'd try the following test. In your application, near the top, add the following logic: extern int truncate(const char* path, off_t length); This should resolve (bypass?) the compilation error relating to truncate being undefined. Next we will find if it is resolved at link time ... i...
