Hardware & Device Integration

Desktop software that talks to instruments, controllers and custom hardware over serial, USB, Modbus and TCP/UDP, built to recover from the faults real devices produce.

Hardware integration is where desktop software meets things that unplug, reboot and return malformed data. Most of the work is defining the protocol precisely and handling every way it can go wrong. Serial links are still everywhere: RS-232 for instruments, RS-485 for multi-drop buses, and USB CDC devices that appear as virtual COM ports. I implement framing, checksums and timeouts explicitly, handle USB re-enumeration when a cable is pulled mid-session, and on RS-485 respect half-duplex turnaround timing. Industrial equipment usually starts with Modbus RTU or Modbus TCP, with OPC UA where a…
