I'm playing around the BLE and trying to get the battery voltage value from the DCDC with a connectivity software example. The example I'm using is the heart rate sensor but the problem should be the same in the others.
I have configured my board in DCDC buck mode. Indeed during the hardware_init it correctly executes the Board_DCDCInit and then the DCDC_Init because in the app_preinclude.h is correctly enabled the DCDC through gDCDC_Enabled_d macro.
The problem arises during the function BleApp_Init which in turn call BOARD_InitAdc. The issue is in the latter because I expect it should be skipped. The body of the BOARD_InitAds is the following:
#if (gDCDC_Enabled_d == 0) || ((gDCDC_Enabled_d==1) && (APP_DCDC_MODE==gDCDC_Mode_Bypass_c))
the first part of the #if is ok, but I guess the second isn't because in app_preinclude APP_DCDC_MODE is a macro initialized with the enum gDCDC_Mode_Buck_c. I suppose that at preprocessor stage the #if statement will be translated as
#if (1==0) || (( 1==1) &&( gDCDC_Mode_Buck_c == gDCDC_Mode_Bypass_c))
and then as
#if (1==0) || ((1==1) && (0==0))
because the preprocessor isn't aware about variable and enum declaration, it just applies a textual substitution and a best-try evaluation. This is why, I think the body of the #if isn't skypped. My patch is just to assign 1 to the APP_DCDC_MODE macro instead of gDCDC_Mode_Buck_c.
