I am doing a project using Mega2560, and need to use several serial ports. One of the serial port need a large TX buffer (e.g.128 bytes), but other serial port only need smaller TX buffer (e.g. 32 bytes). I know I can set the hardware TX buffer size in HardwareSerial.h to 128 bytes, but all 4 seri…

Different buffer size for different serial port of Mega2560 ?

Thanks for everyone. I will try all your suggestions.

BTW my display module is not Nextion display, it is very easy to use and don't require any library. I just found it's homepage at http://www.a-diy.cn
