Note: CustomCallbackTouchDrvInterface use LilyGo T-RGB,T-RGB has three types of screens, each of which uses different touch driver chips. The example demonstrates using the touch interface class and one sketch is suitable for three types of touch chips. The example demonstrates using custom callbacks to read touch or sensors. This method is also applicable to other platforms. The prerequisite compilation platform must support C++11.

Note: I2C communication using custom callbacks

Parameters

addr	7-Bit Device Address
reg	Register address, only needs to be written when writeReg is true
*buf	When isWrite is true, it represents the written buf, otherwise it is the read data buffer
len	When isWrite is true, it indicates the length of data written , otherwise it is the data read length
writeReg	writeReg is the register address that needs to be written, otherwise the register address is not written
isWrite	Data write and read direction, true means write, false means read
