TP_Init

void  TP_Init(unsigned  int  display_width,  unsigned  int  display_height, 

unsigned int readX_ChNo, unsigned int readY_ChNo);

Description Initialize touch panel display. Default touch panel ADC threshold value is set to 3900.
Parameters

- 

display_width:

 set display width. 

- 

display_height:

 set display height. 

- 

readX_ChNo:

 read X coordinate from desired ADC channel. 

- 

readY_ChNo:

 read Y coordinate from desired ADC channel. 

Nothing.

Before calling this function initialize ADC module.

ADC1_Init();               // Initalize ADC module

TP_Init(128, 64, 6, 7);    // Initialize touch panel, dimensions 128x64

None.

TP_Set_ADC_Threshold

void TP_Set_ADC_Threshold(unsigned int threshold);

Description Set custom ADC threshold value, call this function after TP_Init.
Parameters - 

threshold

: custom ADC threshold value. 

Nothing.

TP_Init has to be called before using this routine.

TP_Set_ADC_Threshold(3900);    // Set touch panel ADC threshold

None.
