標題: STM32 HAL庫實現(xiàn)USB bulk數(shù)據(jù)傳輸程序
MCU型號為STM32RCT6  
庫函數(shù)為 HAL庫
初始化代碼生成方式為CUBEMX配置
詳情請見附件源代碼

樓主你好，請問你這個怎么安裝驅(qū)動啊，怎么測試通訊

www點stm32cube點com/article/178  請看這篇文章，也是我發(fā)的里面有驅(qū)動 數(shù)據(jù)通信測試，不過當時MDK的背景設(shè)置成了黑色所以貼圖出來看不清，可以將圖片下載到桌面上用看圖軟件打開看比較清楚，或者在下面的評論里面我有放附件源代碼也可以，驅(qū)動制作采用的是NI VISA來制作的，當時只是驗證個東西而已
