I want to log some data being sent on a TTL 8/N/1 line at 3.3V using only the serial port of my computer. I was thinking of using a MAX3232 transceiver chip to convert the signal as follows:
Would tapping the serial section of the circuit disrupt the TTL communication? Is there a better way to do this? I figure since it needs to go to RS232 eventually anyway, why not just use one chip?
Thanks!
Code:
TTL ---[MAX3232]--------->RS-232---[MAX3232]-------> TTL
