I built a Hegduino V1 kit yesterday.
I try to flash lolin32 as described in Device_Readme.txt, but it doesn't succeed.
Unfortunately, I don't know enough to program with arduino.
1- I try to connect required libraries: AsyncTCP, ESPAsyncWebServer , ADS1X15, ArduinoJson.
when I start the sketch HEG_WIFI_BLE_Lolin32 , I receive the warning "ArduinoJson.h no such file"
2-in Device_Readme.txt :
IMPORTANT STEPIn Documents/Arduino/hardware/espressif/esp32/cores/esp32, open main.cpp
under this adress there is no /hardware/ folder.
please help
If you used the arduino install rather than the dev dependencies you probably won't get that file. The device should work just fine, that step just increases RAM available for the core loop. You need to send the command 't' to it to turn it on.
thanks Joshua, I flashed with your instruction! I connected to wireless. but I can not see any data flow. esp32 goes to sleep mode.
one more question:
in Device_Readme.txt :
IMPORTANT STEPIn Documents/Arduino/hardware/espressif/esp32/cores/esp32, open main.cpp
under this adress there is no /hardware/ folder., is it important?
Yeah there's several things to do, though the setup should take less than 10 min. You need the Arduino ESP32 libraries installed: https://github.com/espressif/arduino-esp32#installation-instructions
You take the zipped folders in "Additional_Dependencies" and copy them to Documents/Arduino/libraries Then you should be able to find the WeMos Lolin32 or Adafruit Feather in Tools -> Board, connect your microcontroller, select the correct port in Tools -> Port. Then you need to be sure to change the partition to the one that says "Minimal SPIFFS", and change the CPU Frequency to 80Mhz. All in the tools menu. After that hit upload and it should work. If you get it to flash and things still don't work from there let me know.
