Software Jitter Filter Improving for Touch Screen Sampling

#define TSP_SAMPLE_NUM 20
#define TSP_ADC_DELAY = 4000;
TIMER interrupt frequency reduce to 50Hz
#define TSP_SAMPLE_RATE_LOW (50) // 50 Samples per Sec
#define TSP_SAMPLE_RATE_HIGH (50) // 50 Samples per Sec
( Re-calculate PCLK and PWM_REGS to ensure if sample frequency equal 50Hz)
