Compile Error Arduino_LoRa_Generic_Sensor with DHT22.cpp module

[kkalbaugh]

When I try to compile the Arduino Generic Sensor I get the following compile errors:

DHT22.cpp: In constructor 'DHT22::DHT22(uint8_t)':

DHT22.cpp:69: error: cannot convert 'volatile uint32_t* {aka volatile long unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment

     _baseReg = portInputRegister(digitalPinToPort(pin));

              ^

DHT22.cpp: In member function 'DHT22_ERROR_t DHT22::readData()':

DHT22.cpp:108: error: 'cli' was not declared in this scope

   cli();

       ^

DHT22.cpp:110: error: 'sei' was not declared in this scope

   sei();

       ^

Tried searching for answers but my C++ skills are too weak at this point to wrap my head around converting integers.

Thanks, Kirby

I probably should add that I'm using a Adafruit M0 LoRa Feather.

We haven't fully tested the sketch with the FeatherM0 and it looks like the DHT lib has some issue on this board. You can avoid the compilation error by commenting:

//#include "DHT22_Humidity.h" //#include "DHT22_Temperature.h"

and also:

//sensor_ptrs[1] = new DHT22_Temperature("TC", IS_NOT_ANALOG, IS_CONNECTED, low_power_status, (uint8_t) 3, (uint8_t) 9); //sensor_ptrs[2] = new DHT22_Humidity("HU", IS_NOT_ANALOG, IS_CONNECTED, low_power_status, (uint8_t) 3, (uint8_t) 9);

change the number of sensors and their index, otherwise just copy the first sensor as follows, just for test:

sensor_ptrs[1] = new LM35("tc", IS_ANALOG, IS_CONNECTED, low_power_status, (uint8_t) A0, (uint8_t) 8); sensor_ptrs[2] = new LM35("tc", IS_ANALOG, IS_CONNECTED, low_power_status, (uint8_t) A0, (uint8_t) 8);

Then move all DHT22* file from the Arduino_LoRa_Generic_Sensor, close the sketch, open it again and compile.

We will try to debug the DHT22 sensor for the FeatherM0 later.
