开始用CH9329进行调试没有问题,由于产品需要,修改默认配置将波特率从9600改成115200后,芯片无法通信了,9600和115200都不能正常通信,恢复出厂默认配置也不起作用。在论坛看到过一个类似的3年前的帖子,但是没有贴出处理办法,这个是哪儿的问题?
修改配置之前,默认配置为:
57 AB 00 88 32 82 80 00 00 00 25 80 08 00 00 03 86 1A 29 E1 00 00 00 01 00 0D 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 26
修改配置信息为:
57 AB 00 09 32 00 00 00 00 01 C2 00 08 00 00 03 6D 04 34 C5 00 00 00 01 00 0D 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 83
