Good job caddish

[Grantorax]

I've been watching your work and I find it very useful , I'm working with HMI Kinco and am communicating with arduino mega using SimpleModbus and certainly have some bugs when using more than 12 records , I wonder if your library could work with chibios / rt or any other RTOs for arduino mega ?, you've tested ?

and when the slave version ModbusXT 'm waiting for it ...;)

I greet and thank your work
