Nintendo switch 硬體外掛程式篇

上一篇介紹了stm32cube的設定後
我們再來更改main.c的內容
首先是#include


接下來是main內的，while上開啟timer中斷
HAL_TIM_Base_Start_IT(&htim9);

以及while迴圈內開啟uart中斷



---
接下來是stm32f4xx_it.c 中斷管理方面
新增這幾行

#include "usbd_customhid.h"
extern USBD_HandleTypeDef hUsbDeviceHS;
extern uint8_t uart_got[8];


在TIM1_BRK_TIM9_IRQHandler timer9中斷那邊新增自動發送
USBD_CUSTOM_HID_SendReport(&hUsbDeviceHS,uart_got,8);


----

修改usbd_custom_hid_if.c的內容
因為我們是high speed，所以要修改CUSTOM_HID_ReportDesc_HS的內容
                HID_UsagePage(0x01),
                HID_Usage          ( 0x05                         ),
                HID_Collection     ( HID_Application              ),
                HID_LogicalMin   ( 0                            ),
                HID_LogicalMaxS  ( 1                            ),
                HID_PhysicalMin  ( 0 ),
                HID_PhysicalMaxS (1             ),
                HID_ReportSize   ( 1                           ),
                HID_ReportCount(13),
                HID_UsagePage          ( 0x09                         ),
                HID_UsageMin(0x01),
                HID_UsageMax(0x0d),
                HID_Input(0x02),
                HID_ReportCount(0x03),
                HID_Input(0x01),
                HID_UsagePage(0x01),
                HID_LogicalMax(0x07),
                HID_PhysicalMaxS(0x3b01),
                HID_ReportSize(0x04),
                HID_ReportCount(0x01),
                HID_Unit(0x14),
                HID_Usage(0x39),
                HID_Input(0x42),
                HID_Unit(0x00),
                HID_ReportCount(0x01),
                HID_Input(0x01),
                HID_LogicalMaxS(0xff00),
                HID_PhysicalMaxS(0xff00),
                HID_Usage(0x30),
                HID_Usage(0x31),
                HID_Usage(0x32),
                HID_Usage(0x35),
               HID_ReportSize(0x08),
                HID_ReportCount(0x04),
                HID_Input(0x02),
                HID_UsagePage(0x00ff),
                HID_Usage(0x20),
                HID_ReportCount(0x01),
                HID_Input(0x02),
                HID_Usage(0x2126),
                HID_ReportCount(0x08),
                HID_Output(0x02),


因為是參考我之前寫得文章HAL庫，但是我又懶得改
所以你會看到一堆錯誤
解決方法是把那些define給叫出來吧
開啟usbd_custom_hid_if.h
