Hello Yuri,
I have successfully get access of gpio from user space and also from C Files.
now i have get a new problem while access uart2. Normal receive transmit i have performed successfully.
I want to connected Blue-tooth with uart2 and for that i have to worked uart2 with RTS-CTS hardware flow control which is not working for me .
Port_setting.c_cflag |= CRTSCTS; // Enable RTS-CTS Hardware Flow Control
In code after enable the flow control the RTS pin goes high and no data will transfer from serial.
please help me tho resolve this problem
Hello,
Are RTS / CTS connections correct?
Regards,
Yuri.
