Hello together,
is it possible to connect the UART (3.5mm stereo jack) with a RS232 Adapter also for other purposes than the Arduino sketches on the PC?
Do i have to quit a progress before or is it reserved for the Arduino-IDE only? Do i have to use a FTDI or MAX232 workaround instead?
Because im trying to connect the UART to a Transformator to regulate the output voltage. The Trafo datasheet says this:
Buerger Electronic - ST800:
Baudrate 19200
Parity N
Bits 8
Stop 1
Puffer 100
no Handshakes
Example:
16 Enter 1 Enter Remote control activated
16 Enter 0 Enter Remote control disabled
48 Enter Response: Voltage-value 8 Bit
49 Enter Response: Current-value 8 Bit
64 Enter 255 Enter = Ua max
65 Enter 255 Enter = Ia max
When i change the baudrate to 19200 and just send a single byte, the shell is just in an endless idle state.
$stty 19200
$echo "48" > /dev/ttyS1
So i'm not sure if im using the commands right or if its just not working, because the stereo jack is not intended to work with other devices.
Thanks for your help in advance.
