I am doing some work with multiple TK1 and I need to transfer data between them.
I’ve decided to use UART to transfer data.
The wiring is done by directly connect pin 68(TX) to 65(RX), 65(RX) to 68(TX), ground to ground ( pin 45 )
Then I test the connection with minicom
I’ve type the command “minicom -b 115200 -o -D /dev/ttyTHS1”
but both side don’t works( nothing appearing when typing words ).
Later, I’ve test the ttyTHS0 with changing wiring between pin 41 to pin 44, pin 44 to pin 41
the minicom test success( two side can display what I’ve type ).
For the third try,I’ve connected ttyTHS0 and ttyTHS1
but only one side result ( one side can display, but not the otherside )
Is there any connection problem with my wiring? or there is damage on the circuit?
Thank you very much.
