example to MultiHoldingRegister

[linhartjar]

It is possible to write an example to MultiHoldingRegister, it reports me an error.

I used it like this and it works. What error do you get?
uint8_t buf[4] = {getHigh(qSetPoint), getLow(qSetPoint), 0, modbusWatchdog};
modbus.writeMultHoldingRegisters(SLAVE_ID, Q_CUR_SETPOINT_ADDR, 2, buf);
