I have several txt files on my SD card that I would like to output to my async webserver. I use the ESP8266 for this. I have tried it with the following call. However, an error is then displayed. It also says that two SD.h libraries were found:
Library/Arduino15/packages/esp8266/hardware/esp8266/3.0.2/libraries/SD
/Applications/Arduino.app/Contents/Java/libraries/SD
the latter is not used.
The error I get is the following:
no matching function for call to 'AsyncWebServerRequest::send(SDClass&, const char [12], const char [10])'
how can I solve this problem?
server.on("/getdata", HTTP_GET, [](AsyncWebServerRequest *request){
request->send(SD, "/subj1_1.txt", "text/plain");
});
