gtkterm是一个用GTK+写的串口终端。
安装：sudo apt install gtkterm
配置文件的位置为：~/.gtktermrc
1 [default] 2 port = /dev/ttyUSB0 //配置端口号 3 speed = 9600 //配置波特率 4 bits = 8 //配置数据位 5 stopbits = 1 //配置停止位 6 parity = none //配置奇偶性 7 flow = none 8 wait_delay = 0 9 wait_char = -1 10 rs485_rts_time_before_tx = 30 11 rs485_rts_time_after_tx = 30 12 echo = False 13 crlfauto = False 14 font = "Monospace 12" 15 term_block_cursor = True 16 term_rows = 80 17 term_columns = 25 18 term_scrollback = 200 19 term_visual_bell = True 20 term_foreground_red = 0.660000 21 term_foreground_blue = 0.660000 22 term_foreground_green = 0.660000 23 term_foreground_alpha = 1.000000 24 term_background_red = 0.000000 25 term_background_blue = 0.000000 26 term_background_green = 0.000000 27 term_background_alpha = 1.000000
其实只改了第二行，还有第三行。
连接上开发板，上电后，在终端敲命令dmesg 来查看安装驱动的信息。也可以使用命令:ls /dev/ttyUSB* 来查看相关信息。
1 [ 5398.036071] usb 2-1.1: new full-speed USB device number 9 using ehci-pci 2 [ 5398.131459] usb 2-1.1: New USB device found, idVendor=10c4, idProduct=ea60 3 [ 5398.131466] usb 2-1.1: New USB device strings: Mfr=1, Product=2, SerialNumber=3 4 [ 5398.131470] usb 2-1.1: Product: CP2104 USB to UART Bridge Controller 5 [ 5398.131474] usb 2-1.1: Manufacturer: Silicon Labs 6 [ 5398.131478] usb 2-1.1: SerialNumber: 008FA13B 7 [ 5398.133162] cp210x 2-1.1:1.0: cp210x converter detected 8 [ 5398.133501] usb 2-1.1: cp210x converter now attached to ttyUSB0
可以看出连接的是ttyUSB0.
在终端敲入命令：sudo gtkterm
如果没有设置默认配置，可以在“Configuration”选项卡设置—>Port—>Boud Rate设置为115200;Port设置为/dev/ttyUSB0
然后打印出信息来。（如果没打印，可以将开发板reset一下）
