The LEDTS can measure the capacitance of up to 8 touch pads, can also drive up to 64 LEDs in an LED matrix. * Touch pads and LEDs can share pins to minimize the number of pins needed for such applications, this is realized by * the module controlling the touch pads and driving the LEDs in a time-division multiplexed manner. * * This device contains LEDTS kernel that has an LED driving function and a touch-sensing function. * * It is recommended to set up all configurations for the LEDTS in all Special Function Registers(SFR) before * enabling and starting LED and/or touch-sense function(s). * * This Low Level Driver(LLD) provides APIs to configure and control LED functionality, Touch-Sense functionality and * features common to both functionalities. * * LED features: * -# Configuration structure to configure LED functionality (XMC_LEDTS_LED_CONFIG_t) and initialization funtion * (XMC_LEDTS_InitLED()). * -# Selection of number of LED columns, active column level and enabling LED funtionality (XMC_LEDTS_InitLED()). * -# Setting line pattern to be displayed on LED column (XMC_LEDTS_SetLEDLinePattern()). * -# Brightness control of LED column (XMC_LEDTS_SetColumnBrightness()). * -# Setting number of columns to be activated (XMC_LEDTS_SetNumOfLEDColumns()). * * Touch-Sense features: * -# Configuration structure to perform basic Touch-Sense functionality (XMC_LEDTS_TS_CONFIG_BASIC_t) settings and * initialization funtion (XMC_LEDTS_InitTSBasic()). * -# Configuration structure to perform advanced Touch-Sense functionality (XMC_LEDTS_TS_CONFIG_ADVANCED_t) settings * and initialization function (XMC_LEDTS_InitTSAdvanced()). * -# Setting number of touch inputs and acculumate count on touch input (XMC_LEDTS_InitTSBasic()). * -# Enabling/disabling of common compare, Touch-Sense counter auto reset and Touch-Sense funtionality. * (XMC_LEDTS_InitTSBasic()). * -# Set number of mask bits for time frame validation and first touch input to be active. (XMC_LEDTS_InitTSAdvanced()). * -# Enable/disable time frame interrupt, external pull-up on touch pin and hardware or software control of * pad turn (XMC_LEDTS_InitTSAdvanced()). * -# Setting size of common oscillation window for all touch-sense inputs (XMC_LEDTS_SetCommonOscillationWindow()). * -# Setting size of oscillation window for a touch-sense input (XMC_LEDTS_SetOscillationWindow()). * * Common features: * -# Global configuration structure XMC_LEDTS_GLOBAL_CONFIG_t and initialization function XMC_LEDTS_InitGlobal(). * -# Selection of Clock source for LEDTS module (XMC_LEDTS_InitGlobal()). * -# Kick-start and stop of LEDTS module (XMC_LEDTS_StartCounter() / XMC_LEDTS_StopCounter()). * -# Read and clear of interrupt status flags (XMC_LEDTS_ReadInterruptFlag() / XMC_LEDTS_ClearInterruptFlag()). * -# Reading of previous active column number (XMC_LEDTS_ReadFNCOL()). * -# Enable/Disable Interrupts(XMC_LEDTS_EnableInterrupt() / XMC_LEDTS_DisableInterrupt()). * @{ */ /********************************************************************************************************************* * MACROS ********************************************************************************************************************/ #if defined(LEDTS0) #define XMC_LEDTS0 ((XMC_LEDTS_GLOBAL_t *) LEDTS0) /**< Typedef for LEDTS kernel0*/ #define XMC_LEDTS_CHECK_LEDTS0(PTR) (PTR == XMC_LEDTS0) #else #define XMC_LEDTS_CHECK_LEDTS0(PTR) 0 #endif #if defined(LEDTS1) #define XMC_LEDTS1 ((XMC_LEDTS_GLOBAL_t *) LEDTS1) /**< Typedef for LEDTS kernel1*/ #define XMC_LEDTS_CHECK_LEDTS1(PTR) (PTR == XMC_LEDTS1) #else #define XMC_LEDTS_CHECK_LEDTS1(PTR) 0 #endif #if defined(LEDTS2) #define XMC_LEDTS2 ((XMC_LEDTS_GLOBAL_t *) LEDTS2) /**< Typedef for LEDTS kernel2*/ #define XMC_LEDTS_CHECK_LEDTS2(PTR) (PTR == XMC_LEDTS2) #else #define XMC_LEDTS_CHECK_LEDTS2(PTR) 0 #endif #define XMC_LEDTS_CHECK_KERNEL_PTR(PTR) (XMC_LEDTS_CHECK_LEDTS0(PTR) || \ XMC_LEDTS_CHECK_LEDTS1(PTR) || \ XMC_LEDTS_CHECK_LEDTS2(PTR)) /** * Defines LEDTS module structure.
