Hello Mikko,

If i ignored Dynamic memory allocation by enabling the macro
DLMS_IGNORE_MALLOC, The software will work without any modifications or else
should i create statically allocated variables for buffers. Please clarify.

BR,

Hi,

Hi,

If you define DLMS_IGNORE_MALLOC you need to allocate space for each object like this:
static gxChargeTable ACTIVE_CHARGE_TABLES[10] = { 0 };
static gxChargeTable PASSIVE_CHARGE_TABLES[10] = { 0 };
const unsigned char ln[6] = { 0, 0, 19, 20, 0, 255 };
if ((ret = INIT_OBJECT(charge, DLMS_OBJECT_TYPE_CHARGE, ln)) == 0)
{
charge.chargeConfiguration = DLMS_CHARGE_CONFIGURATION_CONTINUOUS_COLLECTION;
ARR_ATTACH(charge.unitChargeActive.chargeTables, ACTIVE_CHARGE_TABLES, 0);
ARR_ATTACH(charge.unitChargePassive.chargeTables, PASSIVE_CHARGE_TABLES, 0);
}

We are updating the example where are more example objects.

BR,
Mikko
