在运行过程中，想把ADC增益调大，具体代码找到了DEV8305.C
drvRegAddr = Address_Control_A;
drvDataNew = (Spi_8305_Vars->Ctrl_Reg_0A.GAIN_CS1) | \
(Spi_8305_Vars->Ctrl_Reg_0A.GAIN_CS2) | \
(Spi_8305_Vars->Ctrl_Reg_0A.GAIN_CS3) | \
(Spi_8305_Vars->Ctrl_Reg_0A.CS_BLANK) | \
(Spi_8305_Vars->Ctrl_Reg_0A.DC_CAL_CH1 << 8) | \
(Spi_8305_Vars->Ctrl_Reg_0A.DC_CAL_CH2 << 9) | \
(Spi_8305_Vars->Ctrl_Reg_0A.DC_CAL_CH3 << 10);
DRV8305_writeSpi(handle,drvRegAddr,drvDataNew);
void DRV8305_setCSGain1(DRV8305_Handle handle,const DRV8305_CTRL0A_CSGain1_e gain)
{
uint16_t data;
// read data
data = DRV8305_readSpi(handle,Address_Control_A);
// clear the bits
data &= (~DRV8305_CTRL0A_GAIN_CS1_BITS);
// set the bits
data |= gain;
// write the data
DRV8305_writeSpi(handle,Address_Control_A,data);
return;
} // end of DRV8305_setCSGain1() function
void DRV8305_setCSGain2(DRV8305_Handle handle,const DRV8305_CTRL0A_CSGain2_e gain)
{
uint16_t data;
// read data
data = DRV8305_readSpi(handle,Address_Control_A);
// clear the bits
data &= (~DRV8305_CTRL0A_GAIN_CS2_BITS);
// set the bits
data |= gain;
// write the data
DRV8305_writeSpi(handle,Address_Control_A,data);
return;
} // end of DRV8305_setCSGain2() function
void DRV8305_setCSGain3(DRV8305_Handle handle,const DRV8305_CTRL0A_CSGain3_e gain)
{
uint16_t data;
// read data
data = DRV8305_readSpi(handle,Address_Control_A);
// clear the bits
data &= (~DRV8305_CTRL0A_GAIN_CS3_BITS);
// set the bits
data |= gain;
// write the data
DRV8305_writeSpi(handle,Address_Control_A,data);
return;
} // end of DRV8305_setCSGain3()
无奈嵌入式学的也不怎么样，三个增益代码是在哪里调用的？我想更改增益的话具体是在哪个位置更改的？
