I define object using "volatile struct DATAINTERFACE g.data" in main loop. I got a unexpected result in code.
1. In "if statement" below. program flow can enter Code area. g_data.data.InternalInterface.converter.DAB.vSecRef_Volt = 0.0 (In debeg expression veiw) and the value DAB_MINSEC_VOLTAGE = 300.0f. It does not make send to me.
if ((g_data.InternalInterface.converter.DAB_vSecRef_Volt > DAB_MINSEC_VOLTAGE))
{
Code area.
2. In floating point calculation, the result will be very very small sometime ( < 0.00000000000xxxx). Below is the code of calculation where g_data.debugVars.pu.iPrim = 0.5, DAB_IPRIM_MAX_SENSE = 30.0f.
g_data.InternalInterface.avg.iPrimSensed_Amp = (float32_t)(g_data.debugVars.pu.iPrim * DAB_IPRIM_MAX_SENSE);
I am using opt_level = 0. To me the problem should not due to optimization. I am not sure my structure is correct or not? Please advise.
