RS-232 Interface
The RS-232 interface can be used as a communication channel to a PC running control
software. It consists of female connector J10, where only three pins are connected with the
DCE connections:
●
●
●
So the connection to a PC RS-232 port (DTE) must be done by a direct cable connecting:
●
●
RS-232 signals are obtained and adapted to 5V circuitry by means of the ST232 multi-
channel RS-232 driver and receiver connected to two general purpose IOs (PD7 and PF0).
The microcontroller emulates the RS-232 interface by software.
The ST232 can be powered down, to reduce power consumption when RS232 interface is
not used, by opening jumper J11. In this case, two microcontroller pins (#44 and #52) can
be used as General Purpose IOs (PD7 and PF0).
Motor control
Communication with Motor Control boards is possible through connector J7. This is a 34-pin
connector providing the following signals, in the EVAL6207N case:
