(solved) using VS Code, build can't find uart.h

[mzimmers]

Hi all -

I'm still working my way through the nuances of using the VS Code IDE. I tried adding an include to uart.h to a header file, and it gives an error that the file isn't found.

The build works without error using idf.py.

All the other ESP-IDF header files are found:

Code: Select all

#include "freertos/FreeRTOS.h"
#include "freertos/semphr.h"
#include "esp_crt_bundle.h"
#include "lwip/ip_addr.h"
#include "esp_wifi_types.h"
#include "esp_http_server.h"
#include "uart.h"

I only get an error on uart.h. Is there something special about the drivers directories that requires me to do something extra for this file to be found?

Thanks...

This time it is esp-idf nuance. File with name "uart.h" actually exists, but it is hidden in subfolder:
https://github.com/espressif/esp-idf/tr ... ude/driver

Now, when you look at esp-idf example, you can see how include for such header file should look like:
https://github.com/espressif/esp-idf/bl ... .c#L12-L13

Hi chegewara -

I sort of thought it might be something like that (I tried a few combinations, but not of mine worked). So, why did my build work using idf.py?

Actually it should not build if you include just "uart.h, it has to be "driver/uart.h".

With VS code is different problem. esp-idf is massive API and VS code should warn you that some files are not indexed.

What i do when i work with esp-idf is just add it to workspace next to project, but not copy folder, just add to workspace. It helps to search for functions declaration/definition and if VS code cant handle it i am just using CTRL + SHIFT + F to search all files.
Also keeping espressif docs website open also helps a lot.

That's for sure. Thanks, chegewara.
