when compiling with teensy 3.2 the program compiles OK however when compiling selecting the teensy 4.0 I get the error message:
Code:
\Users\Ojamu\Documents\Arduino\libraries\UTouch\UTouch.cpp: In member function 'void UTouch::InitTouch(byte)':

C:\Users\Ojamu\Documents\Arduino\libraries\UTouch\UTouch.cpp:57:8: error: cannot convert 'volatile uint32_t* {aka volatile long unsigned int*}' to 'volatile uint8_t* {aka volatile unsigned char*}' in assignment

  P_CLK = portOutputRegister(digitalPinToPort(T_CLK));

        ^
.
The issue seems to be with the Utouch library and some typecasting incompatibility.
I have an idea of whats happening but not sure how to resolve it
