Hi, I would like to connect a ttl-to rs485 converter to the serial on gpio of the raspberry pi3 for a modbus project, managed by node red, by selecting the serial /dev/ttyAmao or /dev/serial0, I get the following error, which is non-existent:
[serialconfig:8fc41a7f743f6460] serial port /dev/serial0 error: Error: Error: No such file or directory, cannot open /dev/serial0" ,
checking the hardware I know that the real path is this,
DEVLINKS: /dev/serial1
DEVNAME: /dev/ttyAMA0
DEVPATH: /devices/platform/soc/3f201000.serial/tty/ttyAMA0
MAJOR: ‘204’
MINOR: ‘64’
SUBSYSTEM: tty
TAGS: ‘:systemd:’
USEC_INITIALIZED: ‘7804662’
but it would appear that node red can’t find it
