zhoujie 973dfad5c7 feat(tim): 新增TIM1 PWM时钟输出功能
- 在tim.h中声明TIM1句柄和初始化函数
- 在tim.c中实现TIM1 PWM初始化配置,用于生成ADC采样时钟
- 在main.c中初始化TIM1并启动PWM输出
- 更新STM32CubeMX项目文件(.ioc),添加TIM1配置

🐛 fix(gpio): 修复GPIO配置错误

- 修正gpio.c中ADC_SYNC引脚的GPIO端口配置,使用正确的端口宏
- 移除对PA8引脚的错误配置,PA8现在用于TIM1 PWM输出

♻️ refactor(main): 重构ADC采样触发逻辑

- 移除使用GPIO手动触发ADC采样的代码
- 注释掉TIM2中断回调中控制PA8的代码,该引脚现在用于时钟输出
