Title: METHOD AND DEVICE FOR INTERNAL OSCILLATION CALIBRATION FOR MPOS-BASED MCU
Abstract:
Disclosed are a method and device for internal oscillation calibration for an mPOS-based MCU. The method comprises the steps of: acquiring a current working baud rate measured value of the MCU; converting into a current estimated working frequency of the MCU on the basis of the current working baud rate measured value of the MCU; adjusting the frequency of the MCU on the basis of the current estimated working frequency of the MCU, and adjusting to a standard working frequency. Effectively mitigated is the problem of communication error or failure brought forth by internal oscillation frequency deviation and inaccurate timing.
