STM32 ucosii打印float类型数据，乱码问题

出现的现象:

voltage_value:0.000
voltage_value:-2.000
voltage_value:0.000
voltage_value:26815622264063340000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000.000
voltage_value:-2.000

查找代码

INFO_DEBUG("voltage_value:%.3f", voltage_value[0]);
INFO_DEBUG("voltage_value:%.3f", voltage_value[1]);

解决问题可能出现位置

堆栈没有设置8字节对其，导致float数据出错

OS_STK INPUT_TASK_STK[INPUT_STK_SIZE];

修改方法

__align(8) OS_STK INPUT_TASK_STK[INPUT_STK_SIZE];

重新查看打印效果

voltage_value:6.897
voltage_value:0.156
voltage_value:6.882
voltage_value:0.152
voltage_value:6.837
