//motor: 0 for B 1 for A

实例效果
通电，并测量马达A与B的输出电压，基本相同，电压差在正负003V，输出稳定。
想必能完美解决L9110S 和 L298N两路电机输出电压误差大导致的走不到直线。

有可能是显卡问题
具体自测吧不然买过

你得看步进电机的功率，一般步进电机的电流是1A左右，电机大的能上到8A，极限了。一般用12V供电的，不用看了小功率小电流的，你就当电机走1-4A，12V电机，整套功率应该在20W-40W左右，不建议用电池来驱动电机，特别是用12V的电池，电流大了会发热就大，电池温度高就有一定安全风险。

proteus中的tb6612fng在哪？哪也不在，根本就没有，也不可能这东西。你以为proteus是万能的，要什么有什么吗？其实，它所有的元件是很有限的。不要什么东西都来仿真，还是老老实实地做实物吧。
