Hello
My project and to make a billposter unwinding, who shows what I send it of the PC.
Here is my problem I have to pass on a message (thus characters) of the PC towards a PIC16F876 via the connection RS232.
To send characters I use an interface Visual Basic and as composing of change of signals (+10 /-10V - > +5 / 0V) I use a SP233ACP.
When that I look at the signals of the component there is indeed communication between both but the PIC receive that zeros or then it does not understand what I send it.
I would like to know how to connect the PIC with the PC and if you have an interface to send a mesage I am a buyer.
Thank you
