Serial Console
|
|
==============
|
|
|
|
UART0 is, by default, the serial console. It connects to the on-board
|
|
CP2102 converter and is available on the USB connector USB CON8 (J1).
|
|
|
|
It will show up as /dev/ttyUSB[n] where [n] will probably be 0.

|
Buttons and LEDs
|
|
================
|
|
|
|
Buttons
|
|
-------
|
|
|
|
There are two buttons labeled Boot and EN. The EN button is not available
|
|
to software. It pulls the chip enable line that doubles as a reset line.
|
|
|
|
The BOOT button is connected to IO0. On reset it is used as a strapping
|
|
pin to determine whether the chip boots normally or into the serial
|
|
bootloader. After reset, however, the BOOT button can be used for software
|
|
input.
|
|
|
|
LEDs
|
|
----
|
|
|
|
There are several on-board LEDs for that indicate the presence of power
|
|
and USB activity. None of these are available for use by software.
|
|
|
|
