  • MM32L073TW sos

    使用MM32L073TW的内部晶振,由于板子有尺寸需要,没有加外部晶振,所以使用内部晶振,供电采用5V使用J-LINK识别不出芯片,采用3.3V能够识别出芯片,串口、can均能正常通信,但电源一旦接上5V,程序能执行,但串口、CAN通信均异常 实际测量发现是3.3V供电和5V供电内部HSI变化太大,差不多16%。实际不知道随温度变化还有多大,也不知这样如何校准

  • 25M晶振布线疑问

    [i=s] 本帖最后由 feiyinglala 于 2021-3-12 11:22 编辑 [/i] 当前利用STM32F429做一个板子,用到了晶振25M,现在布线遇到一个问题,因为这个晶振是4脚的封装。1、3脚分别对应STM32的OSC输入输出,拉引线时候难保证两条引线的严格等长(如图中所示),现在有2个疑问:[attach]1642424[/attach] 1.布线时候是否要保证STM32的引脚至晶振的1,3脚引线长度完全一致? 2.Altium Designer中,如何调整器件摆放位置可以实现等长引线。 请各位大佬不吝赐教,谢谢谢谢谢谢

  • 晶振起来后,过一会停止 赏100家园币

    板子能正常工作但是只要和2G模块连接之后 ,2G的天线会在晶振上方通过,跑一会晶振就会死掉。不是次次都这样,我看了一下网上别人说,晶振应该很难起来之后,还停止啊,受天线这些影响(我认为是受到磁场干扰),也应该会自己恢复吧。不是很明白是什么原因造成的,或者有什么解决办法

  • 求助:在我们自己原来cc2640的板子上更换cc2642但不工作

    公司原来有一块可以正常运行cc2640的板子,但最近因为空间不足换了cc2642r1。我们把2640更换成2642,更换了24M的晶振。现在2642运行simple pripheral的时候串口已经可以输出,显示已经在广播,但我们一直搜不到它的广播。我量了一下VDDR是1.68v,用示波器量了48M晶振也起振了。天线用的是RFP单端天线,RFN是空着的。请问对这个问题有什么相关的建议?
