求助：关于触摸屏驱动芯片gt917s配置写入

asddu123456

peizhigt917s该如何写配置位信息， 就是数组那段，按照手册上说的，最后最后一位是en写入位，倒数两位是求和校验位，但是我怎么都得不出来这个结果，想改一个配置信息根本改不了。uint8_t CTP_CFG_GT917S[] ={

};这里贴上野火提供历程的数组，有没有人能告诉我A4B6怎么来的，我怎么求和都求不出来

是以前买的屏幕还是最近买的屏幕，如果是最近买的屏幕是911或者1151的，可以店铺问下技术支持要下对应的CFG文件，
如果是以前买的屏幕也到店铺问下看能不能找到对的CFG文件，例程上可能是弄混乱的
