拖了几个月终于焊好了，然后装的531的keil，PJ到了2032年，成功用jlink烧录

然后我的墨水屏没有任何反应，LED也没有，代码一知半解的，看不太懂，不知道该如何下手，两个IC芯片已经没问题了，可以读写，然后ST25那个NFC芯片手机有反应，打开L-ink那个安卓应用，二值化、模糊处理和标签那些东西手机只会提示一个”正在传输图片，请不要拿走卡片“，我尝试了用纽扣电池加上按键，也尝试了烧录线供电，墨水屏和LED都是没有反应。我也不确定烧录好后的状态，是不是会刷一下屏幕。
如上所述，我该从哪里入手，或者有没有大佬给一份直接墨水屏亮屏的代码，LED我尝试凭借记忆写了一下，也没反应，我也不知道是我没写对还是芯片有问题(正常来说，keil的debugger里面的SWD可以识别，芯片应该是正常的)。
