☆华⼤HC32F003☆---ADC例程分享（不断更新中......） 样例使⽤说明
================================================================
⽇期 版本 负责⼈ IAR MDK 描述
2017-06-07 0.1 虹芯侠客 7.70 5.16A first version
====================================
功能描述
本样例主要展⽰ADC 单通道连续采样⽰例，使⽤中断⽅式获取ADC运⾏状态。 说明：
配置ADC并开始采样，ADC中断发⽣标志连续转换完成，读取累加转换结果
☆ 本⽂旨在抛砖引⽟，其余具体使⽤欢迎加Q：3230875137或加164973950交流。
☆ 华⼤MCU单⽚机资料分享连接
====================================================================== ==========
测试环境
测试⽤板:
辅助⼯具:
⽰波器
电源
辅助软件:
⽆
====================================
提升装置
使⽤步骤
1）打开⼯程编译并运⾏
2）查看串⼝输出
====================================
注意
调试串⼝的使⽤：
调试串⼝在系统时钟使⽤⾼速晶振时可⽤，PIN为P35. 波特率为19200， 8N1. ================================================================
