Lot's of obscure communications platforms on the internet but hopefully this will be a winner when it comes to learning and building cool stuff, I'll cut to the chase. When using pulseview modbus decoder, I can't seem validate the slave address in the RTU packet, I can't understand much of the packet at all if I'm being honest. I understand the slave should be 8 bits, are they inverted or two's compliment? It should be 1. And how do I add the 16 bits of the input register together to land on what it should be, which is register 300, if that makes sense. Massive learning curve for me. Thank you for being kind.
