開始用CH9329進(jìn)行調(diào)試沒有問題,由于產(chǎn)品需要,修改默認(rèn)配置將波特率從9600改成115200后,芯片無法通信了,9600和115200都不能正常通信,恢復(fù)出廠默認(rèn)配置也不起作用。在論壇看到過一個(gè)類似的3年前的帖子,但是沒有貼出處理辦法,這個(gè)是哪兒的問題?
修改配置之前,默認(rèn)配置為:
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
修改配置信息為:
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
