# \<BRD\_APPTWELITE>

This board BEHAVIOR assumes the same wiring as the standard application App\_Twelite. It has constant definitions and readout functions for M1-M3 and BPS pins.

## Constants

The following constants are defined. `BRD_APPTWELITE::PIN_DI1`.

```cpp
static const uint8_t PIN_DI1 = mwx::PIN_DIGITAL::DIO12;
static const uint8_t PIN_DI2 = mwx::PIN_DIGITAL::DIO13;
static const uint8_t PIN_DI3 = mwx::PIN_DIGITAL::DIO11;
static const uint8_t PIN_DI4 = mwx::PIN_DIGITAL::DIO16;

static const uint8_t PIN_DO1 = mwx::PIN_DIGITAL::DIO18;
static const uint8_t PIN_DO2 = mwx::PIN_DIGITAL::DIO19;
static const uint8_t PIN_DO3 = mwx::PIN_DIGITAL::DIO4;
static const uint8_t PIN_DO4 = mwx::PIN_DIGITAL::DIO9;

static const uint8_t PIN_M1 = mwx::PIN_DIGITAL::DIO10;
static const uint8_t PIN_M2 = mwx::PIN_DIGITAL::DIO2;
static const uint8_t PIN_M3 = mwx::PIN_DIGITAL::DIO3;
static const uint8_t PIN_BPS = mwx::PIN_DIGITAL::DIO17;

static const uint8_t PIN_AI1 = mwx::PIN_ANALOGUE::A1;
static const uint8_t PIN_AI2 = mwx::PIN_ANALOGUE::A3;
static const uint8_t PIN_AI3 = mwx::PIN_ANALOGUE::A2;
static const uint8_t PIN_AI4 = mwx::PIN_ANALOGUE::A4;
```

## Methods

Methods are provided to obtain the values of the DIP SW (M1 M2 M3 BPS) pins.

```cpp
inline uint8_t get_M1()
inline uint8_t get_M2()
inline uint8_t get_M3()
inline uint8_t get_BPS()
inline uint8_t get_DIPSW_BM()
```

The return value is not HIGH or LOW, but `0` means that the switch is not set (HIGH side) and `1` means that the switch is set (LOW side).

`get_DIPSW_BM()` returns the value of M1, M2, M3 and BPS pins in order from bit0.

{% hint style="warning" %}
This value is checked at system startup and is not updated by operating the switch thereafter.
{% endhint %}

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
GET https://mwx.twelite.info/latest_en/boards/brd_apptwelite.md?ask=<question>
```

The question should be specific, self-contained, and written in natural language.
The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
