Hi

 I am designing a PIC 16c84 circiut to which is a system of clocks in a whole
building. All these PIC circuits are controlled and updated form a central
location (a pc). for now I am passing data via the rs232. Later on I will pass
data super imposed on the mains. But  unfortunately I still have bugs when
reading the data serially. For some strange reason, the PIC seems to stop after
the first bit. I tried simulating it with a simulus file and everything seems
ok.Does anyone of you have implemented an rs232 successfully (form pc to pic)?
By the way I am using RB0 as a receive pin. Initailly my idea was to generate
an interrupt when the start bit is detected but for some strange reason, this
did not work. The data baud rate required is 110 bits per second.


Hi

What do you mean exactly international time? I am designing a PIC circiut to
work as a system of clocks in a whole building. All these PIC circuits are
controlled and updated form a central location (a pc). for now I am passing
data via the rs232. Later on I will pass data super imposed on the mains. But

unfortunately I still have bugs when reading the data serially. Does anyone
