| 我对ADE7753做如下初始化： void ADE7753_init() { spiwriteint(REG_MODE,Reset_CONFIG); delay_us(60000); spiwriteint(REG_MODE,MODE_CONFIG); spiwriteint(REG_LINECYC,LINECYC_CONFIG); spiwritechar(REG_GAIN,GAIN_CONFIG); spireadlong(REG_RAENERGY); spiwriteint(REG_IRMSOS, IRMSOS_CONFIG); spiwriteint(REG_APOS, APOS_CONFIG); spiwritechar(REG_CH1OS,CH1OS_CONFIG); spiwritechar(REG_TMODE,0xcc); } 然后读TMODE寄存器temp = spireadchar(REG_TMODE);但是读出来的一直是零，问题出在那呢？（REF = 2.43左右，其他输出为低电平）在做项目的，急！谢谢 |
