- Modbus RTU
- CRC Checking
- ATMEL Atmega Slave
Works really good...
Just great. Thanks. But, how do you define response time?
It has been very successful and easy to use.
its very easy and simple to implement. it saved me lot of time..
Lot of thanks for this. it's very easy and very efficient. good job !
