#129628 - newbie interfacing rs232 |
Hi,
would it be possible to interface 3 serial rs232 full duplex lines on at89s52? if so would I need aditional driver/decoder chip to decode signals to data or that is done within at89s52? I'm aware I must use max rs232 voltage regulator is that only this or is it also a driver/decoder? Thanks for your help! regards Tomas |
