How to use IGEP SMARC Expansion RS232
The IGEP SMARC Expansion RS232 through J800 connector.
Connection test
Connect the SMARC base RS232 RX2 and TX1 to host using a null modem cable.
In the host side open a minicom program with:
minicom -D /dev/ttyUSB0 (if you are using a usb-serial converter).
In the SMARC side write the commands:
stty -F /dev/ttyO3 speed 115200 cs8 -cstopb -parenb (in order to configure the device /dev/ttyO3).
echo 'hello host' > /dev/ttyO3 (sent the message "hello host" to ttyO3).
cat /dev/ttyO3 (recive the messages from host)
