Dear Champs,

I am asking this for our customers.

The user uses MISRA-C:2004 to check and and is troubled with this

"#1483-D (MISRA-C:2004 12.6/A) Expressions that are effectively Boolean should not be used in operations with expressions that are not effectively Boolean"

in below two excerpts of codes.

On C28x

1. Calculation_Parameter_A_I16 = Apm_Hvdc_Calibration_00_Str.Apm_Hvdc_Curr_Parm_A_I16;
2. Apm_Lvdc_Cmd_00_Str.Apm_Lvdc_Curr_Cmd_U16 = Derating_Iout_Command_U16;
3. Calculation_Data_Temp_1_I32  = (I32)(Iin_Adc_Avg_Data_U16);
4. Calculation_Data_Temp_1_U32  = (U32)(Calculation_Data_Temp_1_U16);
5. Ads1018_Rx_Data_U16 = Ads1018_Rx_Data_U16 >> 4;
6. Ads1018_Rx_Data_U16 = SpibRegs.SPIRXBUF;

On CLA

1. Hsfb_Cla_Temp_1_CLA_U16 = Hsfb_Cla_Temp_1_CLA_U16 >> 2;
2. Hsfb_Cla_Temp_1_CLA_U16 = (CLA_U16)(AdcaResultRegs.ADCRESULT0);
3. Hsfb_Voltage_Loop_Vars_CLA_STR.Ref = Hsfb_Voltage_Command_CPU_F32;
4. Hsfb_Cla_Temp_2_CLA_F32 = Hsfb_Voltage_Command_CPU_F32 + Hsfb_Ctrl_Param_Vout_Delta_Adc_CPU_F32;
5. Hsfb_Cla_Temp_1_CLA_F32 = Hsfb_Current_Loop_Vars_CLA_STR.Out * 65535.0;

Do you have any suggestion?
