我应用的是dsp f28035.我现在定义了变量CputoClaAAA、CputoClaBBB和VoltFilt
#pragma DATA_SECtiON(CputoClaAAA,"CpuToCla1MsgRAM");
#pragma DATA_SECTION(CputoClaBBB,"CpuToCla1MsgRAM");
Uint16 CputoClaAAA,CputoClaBBB;
#pragma DATA_SECTION(VoltFilt, "Cla1ToCpuMsgRAM");
Uint16 VoltFilt;
在main中初始化
CputoClaBBB=1258;
CputoClaAAA=2536;
MMOVZ16 MR0,@_CputoClaAAA
MMOV16 @_CputoClaBBB,MR0
MNOP ;3 Wait till I8 to read result
MNOP ;4 Wait till I8 to read result
MNOP ;5 Wait till I8 to read result
MNOP ;6 Wait till I8 to read result
MNOP
问题:运行后CputoClaBBB=1258为何还是不能更新为CputoClaAAA的值2536呢,如何让_CputoClaBBB跟随_CputoClaAAA变化呢?
补充:类似的情况
问题:_VoltFilt的值能够跟随A4改变,而CputoClaBBB不能,就是因为_A4 和CputoClaBBB是同一区间,_A4 和_VoltFilt不在同一区间的缘故吗
在这定义
#pragma DATA_SECTION(A, "CpuToCla1MsgRAM");
#pragma DATA_SECTION(CputoClaBBB,"CpuToCla1MsgRAM");
而#pragma DATA_SECTION(VoltFilt, "Cla1ToCpuMsgRAM");
#if LOWPASS
float32 A [FILTER_LEN] = [625, 100, 200, 300, 2000];
#elif HIGHPASS
float32 A [FILTER_LEN] = [625, 100, 200, 300, 2000];//T[0.0625L, 0.25L, 0.375L, 0.25L, 0.0625L]
#endif
MMOV32 MR0,@_A4
MF32TOUI16 MR1,MR0
; MMOVZ16 MR0,@_CputoClaAAA
MMOV16 @_CputoClaBBB,MR1
MMOV16 @_VoltFilt, MR1
