和之前那块一起买的。又画了这个屏幕驱动，还画了灯丝电源驱动，和以前画的stm8核心板在JLC拼板。
亚光黑颜色，不单独收钱！
切好水洗吹干！
忘记给排针加丝印，手写代之。
焊接的时候，脑子发热，以为把层搞错了，结果就掰PT6311引脚，然后反向焊接。焊接好通电电流一下子上1A，检查半天发现没反！
调PT6311程序时顺便发现上次pcb画错了grid和segment，233.当时死活想不通芯片为什么这样设计，原来是自己搞反了。

这个芯片亮品率低，总是有的脚不能输出，这里的grid4通到引脚了但是还是没输出。
飞线到grid18，程序里加判断然后追加赋值解决。
取模绝对不会像上次那样自己算，本来想qt写个小软件。网上一找发现不少米字屏取模软件，PT6311选共阴。然后这个屏0-8的1是a段，再写段小程序左移一位得到字库。
