10.3 Additional option: Using terminal program for interaction
The sample program provides also the possibility to do user interaction via a terminal program
which is running on a computer (e.g. SKwizard which can be found on this CD). To make this
work the sample program uses a further USART I/F for communication.
To connect this USART I/F with a computer the user has to build up a simple circuit which
contains a true RS-232 transceiver (e.g. maxim MAX3232) for converting the voltage levels of a
computer COM-port to the MCU USART voltage levels and vice versa. The MCU USART-pins
SOUT1 and SIN1 are routed to Pin 9 and Pin 10 of the connector USER_CN on the starterkit.
Pin 9, Pin 10 and also Pin 1(GND) of connector USER_CN have to be connected to the
transceiver device. The transceiver is also connected to TXD and RXD of the COM-port.
Please see also the schematic of the starterkit and datasheet of the transceiver device for more
details.
