Hi all, good day.
I am designing a python application running in Raspberry Pi which send out serial message to print on embedded thermal printer.
the communication is using USB to TTL module (CP2102 chip).
currently my application able to print successfully, but there is one issue is, if the USB to TTL serial is connected to my Raspberry Pi USB since switch ON, it will print out a bunch of weird character.
However, if i remove the USB TTL module and plug in again, everything is fine, it able to print nicely.
Does anyone know what is going on?
