Hi,

Been getting a bit confused about the need or lack of need to invert the data to, and from my PIC.

My setup is:


PC---->MAX232------->PIC
PC<----MAX232<-------PIC

Looking at the data sheets, the MAX232 invertes the signal, but I have heard it suggested that the UART needs (and sends) an inverted level anyway, so the 2 cancel out and there is no problem.

Would this then only be a problem if I was uning non-hardware serial pins, and would therefore need to artificially invert everything in software?


Cheers,


Ben
