We're trying to use your library together with an Arduino Uno and an Dali 2 Click Module but we're unfortunately unable to find any of our DALI drivers on the bus. To power our system we're using a Lab PSU set to 16V with a 250mA maximum draw – but this doesn't seem sufficient, or we're doing something else wrong. Does anyone here have experience using the module together with this library? For information we're using digital pin 3 for TX and digital pin 4 for RX. Below is a basic schematic of our connection.
And this is how our code currently looks:
