我想在引脚 N4和 N2上生成一个带有下降沿的 IRQ。
CCS 会生成以下代码：
/** \brief bank interrupt source index base */
#define TISCI_BANK_SRC_IDX_BASE_GPIO0 (90U)
#define TISCI_BANK_SRC_IDX_BASE_GPIO1 (90U)
#define TISCI_BANK_SRC_IDX_BASE_MCU_GPIO0 (30U)
static void Sciclient_gpioIrqSet(void)
{
int32_t retVal;
struct tisci_msg_rm_irq_set_req rmIrqReq;
struct tisci_msg_rm_irq_set_resp rmIrqResp;
rmIrqReq.valid_params = 0U;
rmIrqReq.valid_params |= TISCI_MSG_VALUE_RM_DST_ID_VALID;
rmIrqReq.valid_params |= TISCI_MSG_VALUE_RM_DST_HOST_IRQ_VALID;
rmIrqReq.global_event = 0U;
rmIrqReq.src_id = TISCI_DEV_GPIO1;
rmIrqReq.src_index = TISCI_BANK_SRC_IDX_BASE_GPIO1 + GPIO_GET_BANK_INDEX(15);
rmIrqReq.dst_id = TISCI_DEV_R5FSS0_CORE0;
rmIrqReq.dst_host_irq = CSLR_R5FSS0_CORE0_INTR_MAIN_GPIOMUX_INTROUTER0_OUTP_1;
rmIrqReq.ia_id = 0U;
rmIrqReq.vint = 0U;
rmIrqReq.vint_status_bit_index = 0U;
rmIrqReq.secondary_host = TISCI_MSG_VALUE_RM_UNUSED_SECONDARY_HOST;
retVal = Sciclient_rmIrqSet(&rmIrqReq, &rmIrqResp, SystemP_WAIT_FOREVER);
if(0 != retVal)
{
DebugP_log("[Error] Sciclient event config failed!!!\r\n");
DebugP_assert(FALSE);
}
rmIrqReq.valid_params = 0U;
rmIrqReq.valid_params |= TISCI_MSG_VALUE_RM_DST_ID_VALID;
rmIrqReq.valid_params |= TISCI_MSG_VALUE_RM_DST_HOST_IRQ_VALID;
rmIrqReq.global_event = 0U;
rmIrqReq.src_id = TISCI_DEV_GPIO1;
rmIrqReq.src_index = TISCI_BANK_SRC_IDX_BASE_GPIO1 + GPIO_GET_BANK_INDEX(14);
rmIrqReq.dst_id = TISCI_DEV_R5FSS0_CORE0;
rmIrqReq.dst_host_irq = CSLR_R5FSS0_CORE0_INTR_MAIN_GPIOMUX_INTROUTER0_OUTP_0;
rmIrqReq.ia_id = 0U;
rmIrqReq.vint = 0U;
rmIrqReq.vint_status_bit_index = 0U;
rmIrqReq.secondary_host = TISCI_MSG_VALUE_RM_UNUSED_SECONDARY_HOST;
retVal = Sciclient_rmIrqSet(&rmIrqReq, &rmIrqResp, SystemP_WAIT_FOREVER);
if(0 != retVal)
{
DebugP_log("[Error] Sciclient event config failed!!!\r\n");
DebugP_assert(FALSE);
}
return;
}
调用函数"Sciclient_rmIrqSet"时、我获得返回值-1。
如果我在 SDK 示例"gpio_input_interrupt.c"中只使用一个带有 IRQ 的 PIN、此功能对我来说是没有问题的。
我将 SDK 用于 AM243x [9.2.0.08]
