I have a project to design a converter with data gathered with a MCU to output through USB or RS232. I’m using a MAX232 and an FTDI chip. The chips are connected to the TX/RX of the MCU. Only one will be used at one time. USB 5V will be utilized in both situations.
Is there a best way to jumper or select between USB to RS-232? I’ve thought about removing ground or power to the respective chip but wonder if data streams may power the chips. The chips do not have enable Pins
