Alburg Posted February 11, 2018 Share Posted February 11, 2018 Good morning everyone, I've been playing around with DCS Bios and the RS485 bus lately, but I can't get it to work. Ian already suggested that I load the sketeches onto the Arduinos using a ISP so I bought a USBTinyISP. It loads the Master and Slave sketches on the Mega2560s but the communication doesn't work when connected to a MAX485 board. Then I read that all MAX485 have to share GND, tried that still doesn't work. Anyone have an idea? Thanks and cheers Sven Link to comment Share on other sites More sharing options...
