I am new to esp.
I have install esp-idf and idf-eclipse-plugin, those function well.
But when I install esp-iot-solution, that confused me so much.
I cannot build the example "touch_pad_evb".
Please help me!

Here is all you need:
https://github.com/espressif/esp-iot-so ... rationmake

Which part is confusing you?
iot-solution is using esp-idf which is in submodule folder with checkout hash. If you will update it to some newer version it may not work.

Following output shows the problem.

Done! You can now compile ESP-IDF projects.
Go to the project directory and run:

Background history:

2 weeks ago, I have received ESP32-DevKitC from Digikey.
And I have tested DevKitC successfully after installing esp-idf(ver 4.0), idf-eclipse-plugin.
Recently I have received ESP32-Sense Kit, so I think to test the touch sensor.
But the documents suddenly says to use make command as following.
That lead me to the chaos world.

Download programs
Run make menuconfig to configure the config settings for ESP32-Sense Project, as the screenshot below shows. Run make flash to download programs into the development board.
