That definitely helps. The errors disappear. They reappear when I change the editor window to another file and then back to main. This solves my problem, I don't have to sort through false errors.
Thanks for your help

The snippet is: extern "C" void app_main(void) { initArduino(); esp_err_t err; // Initialize the GPIO ISR handler service err = gpio_install_isr_service(ESP_INTR_FLAG_IRAM); ESP_ERROR_CHECK(err); // Initialize the NVS (non-volatile storage) for saving and restoring the keys err = nvs_flash_init(); E...

I am trying to add Git version control to a project. The project uses several component dirs. The project compiles and runs. Following the EGit documentation I moved the project out of my esp-idf-workspace into it's own directory tree. Still compiles and runs using esp-idf. I used EGit to import the...

In building "https://github.com/manuelbl/ttn-esp32" examples I have run across symbol or field could not be resolved errors. The programs seem to execute correctly so it appears this is an indexer issue. A particular symbol is "max_transfer_sz." It is found in C:/Espressif/frameworks/esp-idf-v4.4.1/...

Here is the CMakeLists.txt file for the Temp18x20 directory: And then you have to add the OneWIre library and it's CMakeLists.txt files

I believe I need a CMakeLists.txt entry so that Temp18x20 will access the Arduino library just like main.cpp. Adding the 3rd line below starts compilation but error are thrown when other portions of the Arduino Library are not found. The CMakeLists.txt file in Temp18x20: idf_component_register(SRCS ...

I created a project using Arduino as an IDF component. The test program works. I then added my own library function. The library function uses Arduino and therefore has a "# include Arduino.h" statement. For the library function I get "fatal error: Arduino.h: No such file or directory." The director...

I have this same problem. I have a program using arduino that compiles and runs in IDF version 3.2. Trying to compile this in 4.1. I received the same errorL: Failed to resolve component 'ethernet'. I followed your suggestions below, still same error. I then edited CmakeFile.txt to refer to "main.cp...

Thanks for the suggestion, but the results are still the same.

This works for me as well, but not when I move the ulp files to a component subdirectory. I'm trying to create a component so that the user is insulated from the ulp code.
Thanks
