Wawilib Interface reference

Not sure if WawiLib will work with your Arduino boards? Look in the WawiLib reference tables how WawiLib works with your hardware:

USB and hardware serial interfaces
Software serial interfaces
Ethernet UDP and TCP
Wifi UDP and TCP

Please look in the appropriate tables to check your intended configuration.

Sylvester Solutions has an extended set of Arduino boards, interfaces and interface converters we use to test WawiLib. The Sylvester Solutions Sandbox is extended every week with new materials and test results. We guarantee that the combinations listed below will work as indicated in the tables. They have been tested intensively on Win7, Win10 and Arduino IDE 1.8.10. Apart from the sandbox there is also a list of combinations that compile OK but were not tested at this moment. Combinations that compile are likely to work, those that do not compile will for sure not work in your configuration.

If you have any questions, please contact us.

Remarks: ⁽¹⁾Not compatible with 5V voltage levels / ⁽²⁾16U2/CH340 programming chip in parallel with UART-USB converter of this brand on ATMEGA 2560 RX0/TX0 not OK / ⁽³⁾Pins 0 & 1 of V1r1 shield can be bent outwards and connected to other pins than pin 0 and 1 via dupont wires / ⁽⁴⁾Set jumper to 3,3V on usb-to-serial 340G / ⁽⁵⁾Be very careful with connectons, in the case of Max 232 shield: (TX-TX on converter) and (RX-RX on converter) is the right choice. For all other examples, connect (rx-tx and tx-rx) / ⁽⁶⁾Do not use at 1200 baud as this will erase the firmware of your board
