stm32f103c8t6的代碼移植到ch32f103c8t6，stm32端點2是正常工作的

ch32嘗試了，端點2和端點3讀出來的數(shù)據(jù)不對

ch32先使能了USB_HP_CAN1_TX_IRQ，要不然觸發(fā)不了USB_HP_CAN1_TX_IRQ

USB 高優(yōu)先級中斷(通道 19)：僅能由同步和雙緩沖批量傳輸?shù)恼_傳輸事件觸發(fā)，目的是保證最 大的傳輸速率

觸發(fā)中斷后進入，EP3_OUT_CALLBACK

g_blaster_rx_req = TRUE

開始緩沖區(qū)拷貝數(shù)據(jù)

到s_recv_buffer這個64字節(jié)數(shù)組，

拷貝出來的數(shù)據(jù)前幾次是和stm32一樣，后面就和stm32拷貝的數(shù)據(jù)出來的數(shù)據(jù)不一樣了

下面這里是配置描述符，和設置端點的操作

ENDP3端點設置操作

端點緩沖區(qū)設置，這里我不確定有沒有設置正確

ENDP0,ENDP1是正常的能識別驅(qū)動

各位大佬幫忙看看到底啥問題啊

你好，理論上端點1跟端點2的操作流程是一樣的啊，實現(xiàn)上存在區(qū)別的話那主要看一下配置，比如端點地址的配置等.

是緩沖區(qū)地址嗎，還是就是端點地址
