Member Function Documentation

virtual void HD44780::Adapter::set_backlight ( uint8_t  flag)
pure virtual

Set backlight on/off.

Parameters
[in]flag.

Implemented in LCD::SR4W< SDA_PIN, SCL_PIN, EN_PIN, BT_PIN >, LCD::DFRobot_IIC, LCD::MJKDZ, LCD::SR3W< SDA_PIN, SCL_PIN, EN_PIN >, LCD::PP7W< D0_PIN, D1_PIN, D2_PIN, D3_PIN, RS_PIN, EN_PIN, BT_PIN >, LCD::PP7W< BOARD::D4, BOARD::D5, BOARD::D6, BOARD::D7, BOARD::D8, BOARD::D9, BOARD::D10 >, and LCD::Debug.

virtual void HD44780::Adapter::set_mode ( uint8_t  flag)
pure virtual

Set data/command mode; zero(0) for command, non-zero(1) for data mode.

Parameters
[in]flag.

Implemented in LCD::SR4W< SDA_PIN, SCL_PIN, EN_PIN, BT_PIN >, LCD::DFRobot_IIC, LCD::MJKDZ, LCD::SR3W< SDA_PIN, SCL_PIN, EN_PIN >, LCD::PP7W< D0_PIN, D1_PIN, D2_PIN, D3_PIN, RS_PIN, EN_PIN, BT_PIN >, LCD::PP7W< BOARD::D4, BOARD::D5, BOARD::D6, BOARD::D7, BOARD::D8, BOARD::D9, BOARD::D10 >, and LCD::Debug.

virtual bool HD44780::Adapter::setup ( )
inlinevirtual

Initiate IO port. Called by HD44780::begin(). Should return true(1) for 8-bit mode otherwise false for 4-bit mode. Default is 4-bit mode.

Returns
bool.

Reimplemented in LCD::SR4W< SDA_PIN, SCL_PIN, EN_PIN, BT_PIN >, LCD::SR3W< SDA_PIN, SCL_PIN, EN_PIN >, LCD::DFRobot_IIC, LCD::MJKDZ, and LCD::Debug.
