HSP用 定義

HSP3.7/3.8 は構造体機能が無いため4byte整数配列(dim)+peek/poke で操作(32/64bitでサイズ・位置が異なる場合はタブで分割)。IronHSP は NSTRUCT(#defstruct/stdim/->)で32/64bit共通。

; HSP3.7/3.8 は構造体機能が無いため、4byte整数の配列変数で操作します。(x64 レイアウト)
; USB_SEND_RAW_COMMAND_PARAMETERS サイズ: 28 バイト(x64)
dim st, 7    ; 4byte整数×7(構造体サイズ 28 / 4 切り上げ)
; Usb_bmRequest : BYTE (+0, 1byte)  poke st,0,値  /  値 = peek(st,0)
; Usb_bRequest : BYTE (+1, 1byte)  poke st,1,値  /  値 = peek(st,1)
; Usb_wVlaue : WORD (+2, 2byte)  wpoke st,2,値  /  値 = wpeek(st,2)
; Usb_wIndex : WORD (+4, 2byte)  wpoke st,4,値  /  値 = wpeek(st,4)
; Usb_wLength : WORD (+6, 2byte)  wpoke st,6,値  /  値 = wpeek(st,6)
; DeviceAddress : WORD (+8, 2byte)  wpoke st,8,値  /  値 = wpeek(st,8)
; MaximumPacketSize : WORD (+10, 2byte)  wpoke st,10,値  /  値 = wpeek(st,10)
; Timeout : DWORD (+12, 4byte)  st.3 = 値  /  値 = st.3   (lpoke/lpeek も可)
; DataLength : DWORD (+16, 4byte)  st.4 = 値  /  値 = st.4   (lpoke/lpeek も可)
; UsbdStatusCode : INT (+20, 4byte)  st.5 = 値  /  値 = st.5   (lpoke/lpeek も可)
; Data : BYTE (+24, 4byte)  varptr(st)+24 を基点に操作(4byte:入れ子/配列)
; ※4byte境界の整数は添字 st.N(N=オフセット/4)で読み書き可。それ以外は peek/poke 系を使用。
; IronHSP は NSTRUCT(構造体)をサポート。32bit/64bit どちらでも同じコードで動作します。
