 V1.0.0
-    初始版本
+	初始版本
 	
 	
 V1.0.1
 	对总钻风摄像头的场中断进行修改，判断标志位为0才采集下一幅图像，避免出现访问冲突
 	修改SPI初始化中的错误，引用了固定的SPI2基地址
 	修复STM中无法使用STM1的问题
-	修复gtm pwm中最大占空比只有GTM_ATOM0_PWM_DUTY_MAX设置有效的问题

+	修复gtm pwm中最大占空比只有GTM_ATOM0_PWM_DUTY_MAX设置有效的问题
+	
+V1.0.2
+	修改模拟IIC默认延时时间为20 
+	添加 需要特别注意P20_2是不能用于输出的，仅仅只有输入的功能 注意事项
+	将摄像头采集DMA改为link传输，可以大大降低DMA中断次数
+	修改默认的软件IIC引脚定义
+	将6050等 需要用到软件IIC的模块，在初始化函数中默认调用模拟IIC初始化
+	添加小钻风驱动程序

 V1.0.0
-    初始版本

 V1.0.1
 	对总钻风摄像头的场中断进行修改，判断标志位为0才采集下一幅图像，避免出现访问冲突
 	修改SPI初始化中的错误，引用了固定的SPI2基地址
 	修复STM中无法使用STM1的问题
-	修复gtm pwm中最大占空比只有GTM_ATOM0_PWM_DUTY_MAX设置有效的问题

+	修复gtm pwm中最大占空比只有GTM_ATOM0_PWM_DUTY_MAX设置有效的问题
+	
+V1.0.2
+	修改模拟IIC默认延时时间为20 
+	添加 需要特别注意P20_2是不能用于输出的，仅仅只有输入的功能 注意事项
+	将摄像头采集DMA改为link传输，可以大大降低DMA中断次数
+	修改默认的软件IIC引脚定义
+	将6050等 需要用到软件IIC的模块，在初始化函数中默认调用模拟IIC初始化
+	添加小钻风驱动程序
