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_CONFIGURATION_POWER_DESCRIPTOR サイズ: 18 バイト(x64)
dim st, 5    ; 4byte整数×5(構造体サイズ 18 / 4 切り上げ)
; bLength : BYTE (+0, 1byte)  poke st,0,値  /  値 = peek(st,0)
; bDescriptorType : BYTE (+1, 1byte)  poke st,1,値  /  値 = peek(st,1)
; SelfPowerConsumedD0 : BYTE (+2, 3byte)  varptr(st)+2 を基点に操作(3byte:入れ子/配列)
; bPowerSummaryId : BYTE (+5, 1byte)  poke st,5,値  /  値 = peek(st,5)
; bBusPowerSavingD1 : BYTE (+6, 1byte)  poke st,6,値  /  値 = peek(st,6)
; bSelfPowerSavingD1 : BYTE (+7, 1byte)  poke st,7,値  /  値 = peek(st,7)
; bBusPowerSavingD2 : BYTE (+8, 1byte)  poke st,8,値  /  値 = peek(st,8)
; bSelfPowerSavingD2 : BYTE (+9, 1byte)  poke st,9,値  /  値 = peek(st,9)

; bSelfPowerSavingD3 : BYTE (+11, 1byte)  poke st,11,値  /  値 = peek(st,11)
; TransitionTimeFromD1 : WORD (+12, 2byte)  wpoke st,12,値  /  値 = wpeek(st,12)
; TransitionTimeFromD2 : WORD (+14, 2byte)  wpoke st,14,値  /  値 = wpeek(st,14)
; TransitionTimeFromD3 : WORD (+16, 2byte)  wpoke st,16,値  /  値 = wpeek(st,16)
; ※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。
