E-Series Modbus Master RTU library with multi slave support?

Firmware Libraries
2

Hi, I’m not sure if this will work but it’s worth to try :wink:
I modify a ModbusMaster lib a little, namely I added a new method:

void ModbusMaster::update_slv_addr(uint8_t u8MBSlave) {
	_u8MBSlave = u8MBSlave;
}

I don’t have any modbus dev at the moment so I can’t tested it but is compiling fine over photon v2.0.1 and the code is borowed from this topic

full code can be found here:

hope will help
