Connection UART serial
Serial pins are the most used pins for DIY users. You can connect to a USB UART adapter as in the picture.
In Linux or OSX, when you plug the USB UART adapter to your computer, the driver should already be installed. Check if you have device registered.
$ls /dev/ttyUSB* /dev/ttyUSB0
you need to have kermit to connect to serial.
$sudo apt-get install gkermit
Then you need to make the configuration file for kermit: ~/.kermrc. The content should be:
set line /dev/ttyUSB0 set speed 115200 set carrier-watch off set handshake none set flow-control none robust set file type bin set file name lit set rec pack 1000 set send pack 1000 set window 5
Now connect to the device using root:
$sudo kermit -c Connecting to /dev/ttyUSB0, speed 115200 Escape character: Ctrl-\ (ASCII 28, FS): enabled Type the escape character followed by C to get back, or followed by ? to see other options. ----------------------------------------------------
When you have finished, press
c to quit kermit.
When connecting the USB UART adapter to your computer, you may need to install drivers for them. The drivers can be download here: somewhere.
Now you will be able to find the serial COM port (in this example:
COM4) in device manger.
Install a terminal software. putty is recommended. You need to set COM port
115200 and connection type
Serial. Click "Open".
You will be displayed a black window. If you turn on your device now, you will see the console output of the box.
