If the HX711 does not appear, ensure Proteus is running with Administrator Privileges or in compatibility mode. Timing Accuracy:
Users adjust a potentiometer (representing the load cell) in the Proteus workspace to observe live weight changes on a virtual LCD or Serial Monitor. 5. Challenges and Solutions Library Recognition:
The use of an HX711 library in Proteus provides a robust environment for debugging weighing scale logic. This methodology significantly reduces development cycles by validating the communication protocol and calibration algorithms in a virtual space before committing to physical PCB assembly.
void setup() Serial.begin(9600); scale.begin(DOUT, CLK); scale.set_scale(2280.0); // Calibration factor scale.tare(); // Reset to zero
Testing Checklist (what to verify in simulation)
| Error | Likely Cause | Solution | |-------|--------------|----------| | "Unknown part HX711" | Library not installed correctly | Re-copy .LIB/.IDX to correct folder | | Simulation runs but DOUT never goes low | Missing pull-up or incorrect timing | Add 10kΩ pull-up on DOUT; reduce clock speed | | Reading always 8388607 | Bridge not connected or scale not initialized | Check A+/A- connections; call scale.tare() first | | Proteus crashes on start | Conflicting library versions | Remove old HX711 library and reinstall only one version |
