Enables updating this range of LCD segment lines.

LCD_SegmentSet#

void LCD_SegmentSet (int com, int bit, bool enable)

Turn on or clear a segment.

Note

• For the Gecko Family, the maximum configuration is (COM-lines x Segment-Lines) 4x40. For the Tiny Gecko Family, the maximum configuration is 8x20 or 4x24. For the Giant Gecko Family, the maximum configuration is 8x36 or 4x40. For the Series 2 Family, the maximum configuration is 4x20. For the Series 2 xG28, the maximum configuration is 8x24 or 4x28.

LCD_SegmentSetLow#

void LCD_SegmentSetLow (int com, uint32_t mask, uint32_t bits)

Update 0-31 lowest segments on a given COM-line in one operation according to the bit mask.

LCD_ContrastSet#

void LCD_ContrastSet (int level)

Configure the contrast level on the LCD panel.

LCD_BiasSet#

void LCD_BiasSet (LCD_Bias_TypeDef bias)

Configure the bias level on the LCD panel.

LCD_VBoostSet#

void LCD_VBoostSet (LCD_VBoostLevel_TypeDef vboost)

Configure voltage booster.

The resulting voltage level is described in each part number's data sheet

LCD_BiasSegmentSet#

void LCD_BiasSegmentSet (int segmentLine, int biasLevel)

Configure the bias level for a specific segment line for Direct Segment Control.

Note

• When DSC is active, each configuration takes up 4 bits in the corresponding Segment Registers (SEGD0L/SEGD1H for Series 0 and 1, SEGDx/SEGDxH for Series 2) which defines the bias level. For optimal use of this feature, the entire SEGD-registers should be set at once in an optimized routine. Therefore, this function shows how to correctly configure the bias levels and should be used with care.

LCD_BiasComSet#

void LCD_BiasComSet (int comLine, int biasLevel)

Configure the bias level for a specific segment line.

Note

• When DSC is active, each configuration takes up 4 bits in the corresponding Segment Registers (SEGD4L/SEGD4H for Series 0 and 1, AREGA/AREGB for Series 2) which defines bias level. For optimal use of this feature, the entire register set should be set at once in a optimized routine. Therefore, this function shows how to correctly configure the bias levels and should be used with care.

LCD_Enable#

void LCD_Enable (bool enable)

Enable or disable LCD controller.

LCD_AnimEnable#

void LCD_AnimEnable (bool enable)

Enable or disable LCD Animation feature.

LCD_BlinkEnable#

void LCD_BlinkEnable (bool enable)

Enable or disable the LCD blink.

LCD_BlankEnable#

void LCD_BlankEnable (bool enable)

Disable all segments while keeping segment state.

LCD_FrameCountEnable#
