部分改动迁移指南
|
||
|
|
========================
|
||
|
|
|
||
|
|
|
||
|
|
usbh_initialize
|
||
|
|
------------------
|
||
|
|
|
||
|
|
usbh_initialize 从 v1.6.0 开始新增 event_handler 参数，通常不需要使用，可以传入 NULL。
|
||
|
|
|
||
|
|
dwc2 glue st
|
||
|
|
----------------
|
||
|
|
|
||
|
|
dwc2 从 v1.5.0 开始 glue 文件内置底层初始化，比如 `usb_dc_low_level_init`，底层依赖 `HAL_PCD_MspInit` 和 `HAL_HCD_MspInit`，必须使用 stm32cubemx 生成。第三方平台不保证有这些函数实现，自行检查。

|
|
dwc2 glue
|
||
|
|
----------------
|
||
|
|
|
||
|
|
dwc2 从 v1.5.1 开始新增 `struct dwc2_user_params`，用于实现多 dwc2 port 不同配置。并替代 `usbd_get_dwc2_gccfg_conf` 和 `usbh_get_dwc2_hccfg_conf` 函数，
|
||
|
|
并增加 `dwc2_get_user_params` 函数实现，举例如下：
|
||
|
|
|
||
|
|
.. code-block:: C
|
||
|
|
|
||
|
|
#ifndef CONFIG_USB_DWC2_CUSTOM_PARAM
|
||
|
|
void dwc2_get_user_params(uint32_t reg_base, struct dwc2_user_params *params)
|
||
|
|
{
|
||
|
|
memcpy(params, ¶m_common, sizeof(struct dwc2_user_params));
|
||
|
|
#ifdef CONFIG_USB_DWC2_CUSTOM_FIFO
|
||
|
|
struct usb_dwc2_user_fifo_config s_dwc2_fifo_config;
|
||
|
|
|
||
|
|
dwc2_get_user_fifo_config(reg_base, &s_dwc2_fifo_config);
|
||
|
|
|
||
|
|
params->device_rx_fifo_size = s_dwc2_fifo_config.device_rx_fifo_size;
|
||
|
|
for (uint8_t i = 0; i < MAX_EPS_CHANNELS; i++) {
|
||
|
|
params->device_tx_fifo_size[i] = s_dwc2_fifo_config.device_tx_fifo_size[i];
|
||
|
|
}
|
||
|
|
#endif
|
||
|
|
}
|
||
|
|
#endif
|
||
|
|
|
||
|
|
host serial
|
||
|
|
----------------
|
||
|
|
|
||
|
|
从 v1.6.0 开始，主机增加 host serial 框架，用于统一所有类串口设备。以下 API 需要使用新 serial API 替换：
|
||
|
|
|
||
|
|
.. code-block:: C
|
||
|
|
|
||
|
|
int usbh_xxx_set_line_coding(struct usbh_xxx *xxx_class, struct cdc_line_coding *line_coding);
|
||
|
|
int usbh_xxx_get_line_coding(struct usbh_xxx *xxx_class, struct cdc_line_coding *line_coding);
|
||
|
|
int usbh_xxx_set_line_state(struct usbh_xxx *xxx_class, bool dtr, bool rts);
|
||
|
|
|
||
|
|
int usbh_xxx_bulk_in_transfer(struct usbh_xxx *xxx_class, uint8_t *buffer, uint32_t buflen, uint32_t timeout);
|
||
|
|
int usbh_xxx_bulk_out_transfer(struct usbh_xxx *xxx_class, uint8_t *buffer, uint32_t buflen, uint32_t timeout);
|
||
|
|
|
||
|
|
替换为：
|
||
|
|
|
||
|
|
.. code-block:: C
|
||
|
|
|
||
|
|
struct usbh_serial *usbh_serial_open(const char *devname, uint32_t open_flags);
|
||
|
|
int usbh_serial_close(struct usbh_serial *serial);
|
||
|
|
int usbh_serial_control(struct usbh_serial *serial, int cmd, void *arg);
|
||
|
|
int usbh_serial_write(struct usbh_serial *serial, const void *buffer, uint32_t buflen);
|
||
|
|
int usbh_serial_read(struct usbh_serial *serial, void *buffer, uint32_t buflen);
|
