UPD6122 and PT2222 encoding method

UPD6122 and PT2222 encoding method The PT2222 is completely consistent with the encoding method of the UPD6122, and the frame code emitted by the code type contains a guide code, and the 8-bit user code (e.g., C7 ~ C0 = 14h) and its reaction code, the 8-bit key data code and its counter code. The figure below shows the structure of this frame code. Figure 6 Data format As shown in FIG. 6 above, the guide code consists of a 9 mS carrier waveform and 4.5 ms turn-off time, which is a boot of the subsequently transmitted code. When repeating the code, the boot code consists of a 9 ms carrier waveform and 2.25 ms turn-off time. Each time the 8-bit code is transmitted, their counter code is also transmitted. When the SEL is connected to the DRV6 foot, the selected 8-bit user code is (C7 ~ C0 = 14h), and its output waveform is shown in Fig. 7, Fig. 8, and Fig. 9: Figure 7 Continuous emission waveform Fig. 9 The second transfer waveform (repetitive code waveform) encodes the "0" and "1" to distinguish between "0" and "1" using a pulse position modulation method (PPM), and the time interval between the utilization, which is the same as shown in FIG.
