Problems solved by technology

Using the method of power-on self-loading to calibrate the oscillator is limited by the ambient temperature and operating voltage of the prefabricated device, as well as the individual process differences of the chip and the inaccurate prefabricated value of the programmer, which may easily cause the remote control to crash; the internal oscillator value is averaged. It can solve this problem, but there are still some defects, but after a long time, the cumulative error of the carrier frequency will shift, and the transmission distance will become shorter, requiring the user to constantly replace the battery to obtain a better carrier and transmission power consumption, which is very inconvenient to use

Embodiment Construction

[0037] refer to figure 1 and figure 2 , a flow chart of an embedded digital oscillating wireless remote controller control method and a schematic diagram of the control principle of the present invention, the control of the embedded digital oscillating wireless remote controller is based on the external auxiliary system clock (ACLK) digitally calibrating the main system clock system oscillator Frequency to obtain the carrier frequency mode to send the letter to achieve, and use the auxiliary system clock (ACLK) to measure the target frequency to automatically adjust the carrier frequency and pulse time of the remote control, including the following steps:

[0038] S1: The wireless remote controller is powered on and reset to initialize the main system clock (MCLK), auxiliary system clock (ACLK), watchdog working clock and T16B timer;

[0039] S2: Select the auxiliary system clock (ACLK) as the real-time clock RTC and set 1 / 128 second as the measurement point;

[0040] S3: U...

Abstract

The invention discloses a control method of an embedded digital oscillation wireless remote controller. The remote controller can work as normal under the severe environment through a way of selectingan internal oscillator; and furthermore, the self-calibration is performed at idle moment according to different time intervals, different working voltages and different temperature differences, thesending carrier precision of the embedded digital ceramic resonator wireless remote controller can be improved as much as possible, and the efficient and economic operation of the embedded digital ceramic resonator wireless remote controller is realized.

Description

technical field [0001] The invention relates to the field of embedded digital oscillating wireless remote controllers, in particular to a control method for embedded digital oscillating wireless remote controllers. Background technique [0002] At present, the wireless remote control mainly uses the internal oscillator to generate a clock signal to calibrate the carrier frequency, which is used for signal pulse modulation, command control, and signal demodulation to transmit and receive electrical signals. It has the same functions as the traditional wireless remote control using an external ceramic oscillator. The advantages of small size, low power consumption, and strong functions also solve the problems of traditional remote controllers relying on external ceramic oscillators, which are easily disturbed by the external environment, short communication distance, low accuracy, and high cost. Since the main system clock (MCLK) of the embedded digital oscillator wireless rem...
