Serial console/zh-hans

在 Ben NanoNote 的背面有 GND, TXD, 和 RXD 引脚，它们可作为 NanoNote 的串行调试口。

由于 Ben NanoNote 的串口是 TTL 电平的，要从这些引脚得到输出，你需要一条 TTL <-> RS232 转接器 (例如 FTDI TTL-232R-3V3 USB-to-TTL 线)。

引脚

• 

  Serial console connected to an FTDI TTL-232R-3V3 USB-to-TTL cable.

• 

  Serial console detached, the tiny wires easily fit under the battery so you can use the NanoNote as usual.

接线

• Connect GND on the NanoNote to GND on your TTL-to-RS232 converter.
• Connect TXD on the NanoNote to RXD on your TTL-to-RS232 converter.
• Connect RXD on the NanoNote to TXD on your TTL-to-RS232 converter.

软件

• The default Baud rate is 57600, 8n1, no hardware or software flow control.
• You can use any terminal program on the PC side, such as minicom. You can use minicom with the following sample config file:

$ cat /etc/minicom/minirc.qi
pu port             /dev/ttyUSB0
pu baudrate         57600
pu rtscts           No
$ minicom -o qi
