AM335XD触摸中断问题



软件包:AM335X_StarterWare_02_00_01_01

我想裸跑,但裸跑软件好象没有电容触摸的代码,我想到LINUX中提取

我查了一下,[XDMA_EVENT_INTR0//TIMER4/CLKOUT1/SPI1_CS1/PR1_PRU1_PRU_R31_16/EMU2/GPIO0_19引脚做为触摸中断的
但我在配套程序中没找到设置中断的函数

目前问题:中断进不去学


谁知道?
1:触摸中断设置函数,或如何设置
2:触摸中断函数

附我自己写的,不知道对不对

IntRegister(SYS_INT_DMA_INTR_PIN0, TouchScreenIsr);
IntPrioritySet(SYS_INT_DMA_INTR_PIN0, 0, AINTC_HOSTINT_ROUTE_IRQ);
IntSystemEnable(SYS_INT_DMA_INTR_PIN0);



谢谢
