所以我回到了zephyr DEVICE_DT_INST_DEFINE,在定义源代码的阶段,我发现它叫做DEVICE_ DT_ DEFINE,所以我再次检查了它的源代码 最后,我找到了这个宏函数,它是最终注册驱动的宏 /* 与DEVICE_DEFINE类似,但采用节点id和开发人员名称,并带有尾随 * 来自外部devicetree的依赖句柄 */ #defineZ_DEVICE_DEFINE(node_id,...
Gadget Device 准备好了 Endpoint 资源链表以后,通过 usb_add_gadget_udc() 注册。这样就可以 Function Layer 就可以通过调用 Gadget Api 来动态分配 Endpoint 了。例如: static int acm_bind(struct usb_configuration *c, struct usb_function *f) { /* allocate instance-specific endpoints */ /* (1) 从 ...
DT_DRV_INST(1)表示led1的Node ID,等价于DT_INST(1, gpio_leds)因为devicetree.h中,有 #define DT_DRV_INST(inst) DT_INST(inst, DT_DRV_COMPAT) Inst API提供了基于下标的访问DeviceTree节点的方式。 接下来,下图用宏函数的方式定义了一个代码模板,内部定义了led 驱动程序所需的变量、device...

* device from a devicetree node, use DEVICE_DT_DEFINE() or * DEVICE_DT_INST_DEFINE() instead. Contributor andyross May 13, 2024 Seems like this documentation block should have something to say about what REINIT means and how this differs from DEVICE_DEFINE(). Like, the doc lines belo...

An FPD is a field programmable logic device which contains non-volatile, re-programmable memory to define its internal wiring and functionality. The contents of this non-volatile memory are called the FPD image or FPD firmware. Over the lifespan of an FPD, FPD firmware images ...
