Pulse width varies by oscillation resistance; refer to the sample for specifics. 芯片/电阻 Chip /Resistor 同步头时间 Synchronization header time 高电平时间 High level time 低电平时间 Low level time EV1527/330K 10.5MS 1MS 360US EV1527/270K 8.6MS 840MS 280US HS1527/270M 10.5MS 1MS 360US 学习码遥控器是一款24位数据的遥控器,前面20位是遥控器的地址数据, 后4位是遥控器的键值.前20位实现百万组不同的地址编码,遥控器地址 同步头时间 百万不 重 复.后4位 无 组 合 的 情 况 下 键 值 分 别 是8 4 2 1 ( 1 6进制),遥控器 键值固定 不变. The 24-bit learning code remote uses 20 bits for unique address (millions of combinations) and 4 fixed hexadecimal key values (8421 format) 学习码遥控器需通过单片机解码，从而实现遥控的一对一的控制。用前遥 控器与接收控制端需要进行遥控配对操作。如下图 MCU 的第5脚外接学 习键， 按下学习键5脚有高低电平变化的时候，程序认为是学习配对状态 ，立即按遥控 器，配对完成，程序退出配对状态。也可通过上电前几秒为 学习状态，按遥控器 任意键，来完成配对。配对为了更直观的看到效果， 如下图的MCU 第三脚可接 一 个 LED 来进行指示，当第五脚有电平变化， 进入学习状态时，可以点亮 LED 来指示，学习成功后 LED 可以闪烁几次 来进行指示。以上二个方法是我们遥控 行业常用的配对方式，程序员也可 以根据自己产品的特点，设计不同的操作方法， 以上仅供参考。 The learning code remote control needs to decode via a microcontroller to achieve one-to-one remote control. Before use, the remote control and the receiving control terminal need to be paired. As shown in the figure, the 5th pin of the MCU is externally connected to a learning button. When the 5th pin has high-low level changes due to pressing the learning button, the program considers it as the learning pairing state. Press the remote control immediately to complete the pairing, and the program exits the pairing state. Alternatively, the learning state can be entered within the first few seconds after power-on, and pairing can be completed by pressing any key on the remote control. For a more intuitive display of the pairing effect, the 3rd pin of the MCU as shown in the figure can be connected to an LED for indication. When the 5th pin has a level change and enters the learning state, the LED can be lit for indication. After successful learning, the LED can flash several times for indication. The above two methods are commonly used pairing methods in the remote control industry. Programmers can also design different operation methods according to the characteristics of their products. The above is for reference only. 地址码：38 CF3 单片机解码在样品的脉宽的基础上，程序放宽正负20%。避免遥控不灵敏或 无 法遥控的现象 The microcontroller decoding relaxes the program by ±20% based on the sample pulse width to avoid remote control insensitivity or failure. 输出编码的格式：Output the encoding format 同步 CO-C19(100万组) D0 D1 D2 D3 同步 ： k——124LCK 12LCK 4LCK 12LCK CLOCK 定 义 ： 1LCK=8 4LCK 个OSC DATA(H): 4LCK K0-K3 按键组合表：K0-K3 (K0-K3 Key Combination Table) K3 K2 K1 K0 D3 D2 D1 D0 0 0 0 1 0 0 0 1 0 0 1 0 0 0 1 0 0 0 1 1 0 0 1 1 0 1 0 0 0 1 0 0 0 1 0 1 0 1 0 1 0 1 1 0 0 1 1 0 0 1 1 1 0 1 1 1 1 0 0 0 1 0 0 0 1 0 0 1 1 0 0 1 1 0 1 0 1 0 1 0 1 0 1 1 1 0 1 1 1 1 0 0 1 1 0 0 1 1 0 1 1 1 0 1 1 1 1 0 1 1 1 0 1 1 1 1 1 1 1 1 FCC Caution.
