- начальный загрузчик для плат elbear, elsomik обновлен до версии 0.2.0 - исключено появление краткосрочных просадок при работе ШИМ с максимальным коэффициентом заполнения - добавлена возможность пропускать код стандартного обработчика прерываний при использовании пользовательского обработчика - добавлена возможность конфигурирования вывода на вход с притяжкой к земле (INPUT_PULLDOWN) - исправление известных ошибок

Receives from the hardware serial, sends to software serial.

Receives from software serial, sends to hardware serial.

|
The circuit:
|
|
* RX is digital pin 2 (P0_10) (connect to TX of other device)
|
|
* TX is digital pin 6 (P0_2) (connect to RX of other device)
|
|
|
|
Note:
|
|
Not all pins on the Elbear Ace-Uno/Ace-Nano support interrupts,
|
|
so only the following can be used for RX: 2, 3, 4, 5, 8, 9
|
|
Elsomik board pins with interrupts: P0_8, P1_4, P1_5, P1_6, P1_9, P1_10, P1_15, P2_7
|
|
Start board pins with interrupts: P0_10, P0_12, P0_13, P0_14, P0_15, P1_9, P1_15
