在VB，這個(gè)函數(shù)中（iWriteBuffer, 指向一個(gè)緩沖區(qū),放置準(zhǔn)備寫出的數(shù)據(jù)），如何在調(diào)用該函數(shù)時(shí)初始化一個(gè)一維數(shù)組賦值給iWriteBuffer進(jìn)行輸出？謝謝

可以通用windows的拷貝函數(shù)進(jìn)行數(shù)據(jù)拷貝。

不明白

參考CH372EVT.ZIP:http://m.findthetime.net/download/list.asp?id=29 里面的VB\BULK例子，CH375WriteData的第2個(gè)參數(shù)怎么初始化的。

其實(shí)我用過(guò)其它函數(shù)像CH341StreamI2C(mIndex, 2, buffer, 0, iBuff)在里面也成功，但是用CH341WriteRead就卡死，不知里面具體參數(shù)怎么設(shè)置，也不知道這個(gè)函數(shù)支不支持在VB中調(diào)用
