If there is no special need, it is not recommended to use at too high or too low temperatures.
6.3 The bit error rate is too high
It is nearby the same frequency signal interference, away from the interference source or modify the frequency,
channel to avoid interference;
The clock waveform on the SPI is not standard. Check whether there is interference on the SPI line. The SPI
bus should not be too long.
Power supply is not ideal may also cause garbled codes, be sure to ensure the reliability of the power supply;
Extension wire, feeder quality is poor or too long, will also cause high bit error rate.
