各位大神求救，液晶屏写入后导致单片机重启，加电容无效。怎么解决呢？

非常感谢各位。
问题解决了。换了一片同型号的还有不同型号的都试了一下，都可以，只有那一片不可以，但是那一片烧录个别的测试程序也ok。很奇怪。小概率的事件遇到了。
正在研究屏幕显示汉字，还在乱码，图片是ok的。搞定了和大家分享。

淘宝买的便宜货，在论坛各位大神的帮助下终于点亮了，可是还是有些问题。
刷图的时候其他未刷部分是白色的，而且出现非常明显的从上到下刷屏的样子，，根本看不太清楚，改了单片机的频率也不行，还是出现刷屏，只是整个过程快了很多。
无法达到一直显示的目的。问题找到了，是单片机一直在重启。
可是每次都是写入完图片的数据之后重启。如果只写入初始化不会重启。我在5v电源输入端和单片机输入端（3.3v）并联了100uf的电容，问题依然如故。陷入死结了。
我该怎么办呢？
接线图如下。我在1117的输入输出都加了100uf的电容，还是不行。供电是用的5v1A的插头。

你主程序里不是一直刷屏吗？

放在外面也这样的，只刷入一次也这样，不明白为什么呢

如果你不停的刷而且 MCU 速度慢的话是这样的.
你至少发个程序给大家看看啊.

内存不够？瞎猜的

问题解决了。换了一片同型号的还有不同型号的都试了一下，都可以，只有那一片不可以，但是那一片烧录个别的测试程序也ok。很奇怪。小概率的事件遇到了。

我用的确实是小内存的。
