TIM2或TIM3可以连接到正交编码器和向上/向下计数吗？数据表说是，但参考手册含糊不清。有没有人为这些计时器附加编码器？ #sendrature-encoder-rotary-tim3＃stm8l-tim2 - / - tim3以上来自于谷歌翻译以下为原文 Can TIM2 or TIM3 be attached to a quadrature encoder and up/down count? The data sheet says yes, but the reference manual is vague. Has anyone attached an encoder to these Timers yet?#quadrature-encoder-rotary-tim3 #stm8l-tim2-/-tim3

你好，我正在使用L6482芯片的'L6482H发现板'设计实例，用于制作我自己的pcb板，使用相同的mosfet等。在这一刻，我的董事会运行良好 步进电机和。两个命令，Move（DIR，N_STEP）和Run（DIR，SPD）都运行得很好。但是当我使用Run（DIR，SPD）命令时 步进电机，步进电机几乎没有任何扭矩，而且很容易堵住轴。只有在非常低的速度下它们才有一定的扭矩。我明白我必须改变我的R感值，但我不确定如何计算3A步进电机的这个值。请问，计算R sense正确值的方法是什么？提前致谢，瓦伦丁 ＃l6482h＃l6482＃r-sense以上来自于谷歌翻译以下为原文 Hello,I am using 'L6482H discovery board' design example for L6482 chip, for making my own pcb board, using the same mosfets, etc.At this moment, my board runs really well with stepper motors and . Both commands, Move (DIR, N_STEP) and Run (DIR, SPD),run very well.But when I use Run (DIR, SPD) command with stepper motors, stepper motors almost do not have any torque, and it is easy to block the axis. Only at very low speed they have sometorque.I understand I have to change my R sense values, but I am not sure the way of calculating this value for 3A stepper motors.Please, what is the way of calculating the right value of R sense?Thanks in advance,Valentin #l6482h #l6482 #r-sense

我们在新设计中使用L6470。我们发现当我们移动到一个位置然后反向时，我们发现新位置短了2或3步。在此初始化错误之后，所有未来在同一方向上的移动都是正确的。如果方向再次反转，我们会在第一步中再次失去2或3个步骤。我们在步进轴上安装了一个编码器，确认了这一动作。我们还在皮带上放了一个百分表，并确认我们确实错过了这两个或三个步骤。 ST工程师请求回复，因为我们没有关于如何解决这个问题的想法。以上来自于谷歌翻译以下为原文 We are using the L6470 in a new design. We have found that when we move to a position then reverse direction we find that the new position comes up short by 2 or 3 steps. After this initail error all future moves in the same direction are correct. If the direction is reversed again we lose the 2 or 3 steps again on the first move. We have an encoder mounted on the stepper shaft which confirms this action. Also we have placed a dial indicator on the belt and confirmed that we are indeed missing these 2 or 3 steps. ST engineers pleas reply as we are out of ideas on how to fix this issue.
