Another commonly encountered hurdle relates to communication between microcontrollers/microprocessors and the connected device via I²C/SPI interface options provided by ADXL345 chipset.
To address these glitches:

5) Verify wiring connections properly – double-check all physical connectivity aspects such as cable orientation/snugness/errors leading from host controller pins/solder points till respective ACs’ corresponding ones too;

6) Slave address selection — make sure there aren’t conflicts arising among devices sharing similar addresses within network topology/applications/design environments being implemented [this trouble also applies while cohabiting multiple sensors on same bus] – Resolve such conflicts by addressing any conflicting hardware addresses, as per the datasheet.

Issue #3: Power-related anomalies

Sometimes, users face problems when they power up their ADXL345. These issues can range from unexpected shutdowns to abnormal heating.
To overcome them:

7) Stability of supply voltage: Verify if your power source provides a stable and compatible voltage level with ADXL345’s specifications. Sudden changes or inadequate supplies may lead to unpredictable behavior.

8) Interference analysis – Identify potential electromagnetic interference (EMI) sources present near/during measurement setup/configuration [electronic circuits/gadgets/transformers in close proximity]. Employing shielding methods like Faraday cages or minimizing closeness between EMI-emitting objects & accelerometer assembly might alleviate this matter;

9) Proper heat management – Excessive heating could damage an electronic device like ADXL345 over time. Adequate ventilation through designs encompassing passive cooling mechanisms via thermal pads/enhanced PCB layouts/shielding materials help dissipate excess generated heat effectively for safe operations during extended periods without overheating symptoms appearing abruptly-

It is essential to follow these troubleshooting tips diligently while dealing with common issues faced in the operation of an ADXL345.Accelerometers are sensitive instruments designed to capture precise motion data accurately—if not adequately handled; discrepancies might arise unexpectedly from nowhere!
