LED1: Began fade up to duty 8191
LED1: Began fade down to duty 8
LED2: Achieved maximum voltage on the LED = 3.29V.
LED1: Began fade up to duty 8191
LED1: Began fade down to duty 8
LED2: Achieved minimum voltage on the LED = 1.76V.
Button SW1 must affect LED1, and button SW2 must affect LED2. The initial state of the LED is off. One press switches LED on, and another one switches it off. You must avoid switch bounce and be sure that the single button press always works properly.

I (305) uart: queue free spaces: 10
I (305) TX_TASK: Wrote 62 bytes
Connect UART in second USB port and run this command:
screen /dev/ttyUSB0 115200
RED GREEN BLUE DEFAULTBefore that, I recommend setting it up in .screenrc:
nano ~/.screenrc
Copy this code:
# Выключаем приветствие
startup_message off
# включаем визуальный звонок
vbell on
# буфер для сохраненных строк делаем 10000
defscrollback 10000
# кастомим строку состояния

Some useful commands:
screen -list
There is a screen on:
