条件1.使用stm32f103c8t6,c语言编程条件2.使用PA1,PA2,PA3,PA4,PA5，PA6配置成上拉输入,根据6个引脚的电平高低生成。例如000000表示6引脚电平全为0,并使用串口1以字符串形式发送该二进制数到PC端。统计该二进制数中0的次数记作zeo_count;条件3.配置PA11引脚为下拉输入;条件3.串口1使用中断接收数据,帧头FF,结束符0X0D,0X0A.帧头不是FF则重新接收，不以0X0D,0X0A结束符则重新接收;条件4.若PA11电平为0或者串口1没有接收到数据,则记录1分钟内条件2中的最大值zeo_count;记作zeo_count_max;条件5.若zeo_count_max大于zeo_count,打开蜂鸣器;若zeo_count_max小于等于zeo_count,则zeo_count_max==zeo_count;条件6.若PA11电平为1且串口1接收数据不为空,则若串口接收字符串为"1",关闭蜂鸣器;若串口接收字符串为"2",打开蜂鸣器;则若串口接收字符串为"3"且条件2中zeo_count=1,则发送字符串"拿取数量正确",否则发送拿取数量异常;则若串口接收字符串为"4"且条件2中zeo_count=2,则发送字符串"拿取数量正确",否则发送拿取数量异常;则若串口接收字符串为"5"且条件2中zeo_count=3,则发送字符串"拿取数量正确",否则发送拿取数量异常; 则若串口接收字符串为"6"且条件2中zeo_count=4,则发送字符串"拿取数量正确",否则发送拿取数量异常;则若串口接收字符串为"7"且条件2中zeo_count=5,则发送字符串"拿取数量正确",否则发送拿取数量异常;则若串口接收字符串为"8"且条件2中zeo_count=6,则发送字符串"拿取数量正确",否则发送拿取数量异常;

我理解你的问题是需要我编写一个程序，根据6个引脚的电平高低生成二进制数，并使用串口1以字符串形式发送该二进制数到PC端。同时，需要统计该二进制数中0的次数记作zeo_count，并记录1分钟内条件2中的最大值zeo_count_max。如果zeo_count_max大于zeo_count，则打开蜂鸣器；如果zeo_count_max小于等于zeo_count，则zeo_count_max等于zeo_count。如果PA11电平为1且串口1接收数据不为空，则根据接收到的字符串执行相应的操作。

该程序使用了定时器2来实现计数器功能，每秒钟触发一次中断。在中断处理函数中，读取6个引脚的电平高低，统计0的个数，并将6个引脚的状态以16进制字符串的形式发送到串口1。同时，如果计数器达到1分钟，且PA11电平为0或者串口1没有接收到数据，则记录1分钟内0的最大个数，并根据最大0的个数打开或关闭蜂鸣器。如果PA11电平为1且串口1接收到数据，则根据接收到的字符串执行相应的操作。

请注意，这只是一个简单的示例程序，可能存在一些问题，需要根据实际情况进行修改和优化。
