call of overloaded 'begin(int)' is ambiguous - arduino

Question

Ive got a ESP32-S2 and just try to test the circuit and the Board with this simple script.
Error Code says.
ziel_19-09-2020.ino: In function 'void setup()':
ziel_19-09-2020:85:18: error: call of overloaded 'begin(int)' is ambiguous
mcp1.begin(addr1);

Answer 1

If you use #define addr1 0 the compiler can't choose between begin(pointer) and begin(int), because the value from #define could be a pointer.
If you set the I2C address as typed constant of type uint8_t, which is the type of the address parameter in the begin function with I2C address, the compiler will use the right function.
So set the addresses this way const uin8_t addr1 = 0;

Answer 2

Basically, the Adafruit_MCP23017 library is bad. You may need to edit the library. There are actually two begin functions that you could potentially be calling, and Arduino has no idea which one you want.
Option 1:
You could add the following line outside of setup():
#define Wire TinyWireM
and changing your begin functions to:
mcp1.begin(addr1, &Wire);
mcp2.begin(addr2, &Wire);
mcp3.begin(addr3, &Wire);
mcp4.begin(addr4, &Wire);
mcp5.begin(addr5, &Wire);
mcp6.begin(addr6, &Wire);
mcp7.begin(addr7, &Wire);
mcp8.begin(addr8, &Wire);
Option 2:
Currently, the two begin functions in the library look like this:
void begin(uint8_t addr, TwoWire *theWire = &Wire);
void begin(TwoWire *theWire = &Wire);
My recommendation above is based on the assumption that you are using the first function.
Your second option would be to remove the second function.
Remove the following from Adafruit_MCP23017.cpp (starting form line 133):
/**
* Initializes the default MCP23017, with 000 for the configurable part of the
* address
* #param theWire the I2C object to use, defaults to &Wire
*/
void Adafruit_MCP23017::begin(TwoWire *theWire) { begin(0, theWire); }
Remove the following from Adafruit_MCP23017.h (line 27):
void begin(TwoWire *theWire = &Wire);
I can further guide you in editing the library if needed
