V1.7.0: 新硬件板型引脚重排(不兼容老板,迁至shuichan_new) - 引脚重排: 继电器/反馈/NET_LED/CAT_PWR/BT_MODE/EEPROM I2C/W25Q64/OLED 全部按新原理图重定义(APP+BL同步) - CAT_PWR(PC1)改接DCDC使能脚,开漏,逻辑反相: 释放=工作,拉低=掉电; BL门禁期拉低保持4G断电 - CAT_RST(PA4)直连Air780E复位脚,改开漏,修复cat_reset复位后未释放的隐患 - 新增HR_IN(PA8)红外对管缺料检测: 下拉输入,高=缺料则停止投料关继电器1(只记日志),不接传感器不影响投料 - 新增KEY1~4(PC6/PC7/PB14/PB15)上拉输入初始化,功能预留 - 取消PA8手动模式开关(MANUAL_MODE) - 版本号1.6.5->1.7.0; EEPROM布局/OTA结构/云平台协议不变
