CAUTION: Do not operate at or near the maximum ratings listed for extended periods of time. Exposure to such conditions may adversely impact product reliability and
result in failures not covered by warranty.
IMPORTANT NOTE: All parameters having Min/Max specifications are guaranteed. Typ values are for information purposes only. Unless otherwise noted, all tests are

1、STlink /V2 不提供电源，所以运行需要另外供电 2、STM32用ST-LINKV2下载程序时必须重启一下STM32，才能工作，这是为什么呢？ uitilities里面 没有勾选:reset and rum 假设这个使能信号是用来控制电机的，如果悬空的话，此信号线可能在上电后（或在运行中）受到其它噪声干扰而误触发为高电平，从而导致电机出现不期望的转动，这肯定不是我们想要...[详细]
