At the top of the drop down list, select the option to "Add Library". 34 | 35 | You will be prompted to select this zipped library. 36 | 37 | Return to the Sketch > Import Library menu. You should now see the library at the bottom of the drop-down menu. It is ready to be used in your sketch. 38 | 39 | The zip file will have been expanded in the libraries folder in your Arduino sketches directory. 40 | 41 | NB : the library will be available to use in sketches, but examples for the library will not be exposed in the File > Examples until after the IDE has restarted. 42 | 43 | 44 | KNOWN ISSUES 45 | ================================================================= 46 | It is not compatible with ARDUINO LEONARDO and not tested under ARDUINO DUE and newer boards. 47 | 48 | TODO List 49 | ================================================================= 50 | Common to Master and Slave: 51 | 52 | 1) Implement other Serial settings: parity, stop bits, ... 53 | 54 | 2) End frame delay, also known as T35 55 | 56 | 3) Test it with several Arduino boards: UNO, Mega, etc.. 57 | 58 | 4) Extend it to Leonardo 59 | 60 | Master: 61 | 62 | 1) Function code 1 and 2 still not implemented 63 | 64 | 2) Function code 15 still not implement 65 | 66 | 3) Other codes under development 67 | 68 | -------------------------------------------------------------------------------- /Arduino_ESP8266_ Modbus_Industrial_Applications/1.

At the top of the drop down list, select the option to "Add Library". 34 | 35 | You will be prompted to select this zipped library. 36 | 37 | Return to the Sketch > Import Library menu. You should now see the library at the bottom of the drop-down menu. It is ready to be used in your sketch. 38 | 39 | The zip file will have been expanded in the libraries folder in your Arduino sketches directory. 40 | 41 | NB : the library will be available to use in sketches, but examples for the library will not be exposed in the File > Examples until after the IDE has restarted. 42 | 43 | 44 | KNOWN ISSUES 45 | ================================================================= 46 | It is not compatible with ARDUINO LEONARDO and not tested under ARDUINO DUE and newer boards. 47 | 48 | TODO List 49 | ================================================================= 50 | Common to Master and Slave: 51 | 52 | 1) Implement other Serial settings: parity, stop bits, ... 53 | 54 | 2) End frame delay, also known as T35 55 | 56 | 3) Test it with several Arduino boards: UNO, Mega, etc.. 57 | 58 | 4) Extend it to Leonardo 59 | 60 | Master: 61 | 62 | 1) Function code 1 and 2 still not implemented 63 | 64 | 2) Function code 15 still not implement 65 | 66 | 3) Other codes under development 67 | 68 | -------------------------------------------------------------------------------- /Arduino_ESP8266_ Modbus_Industrial_Applications/3.
