Part Number: MAX3232E
MAX3232EIDR 这款芯片115200通讯不成功，9600可以，需要帮问下可能是什么原因
您好，
请确认MAX3232E 3-V to 5.5-V Multichannel RS-232 Line Driver and Receiver With ±15-kV IEC ESD Protection datasheet (Rev. E) "9.2 Typical Application"中的电路及推荐的电容值。通讯异常时，V+ V-脚电压是多少？
RS232通讯线缆有多长？请检查 TX 线路的负载，建议电容小于 1000pF。
下面帖子讨论了类似问题，请参考。
