Code:
float get_float_pin_val(QString nV){
char nHv[strlen(nV.toStdString().c_str()) + 1];
strcpy(nHv, nV.toStdString().c_str());
hal_data_u *value;
hal_type_t type;
bool *con = nullptr;
float checkVal = 0;
int r=hal_get_pin_value_by_name(nHv,&type,&value,con);
if(r!=0){
checkVal = -1;
}
else {
checkVal = value->f;
}
return checkVal;
}
These func for load pin value that is MB2HAL register .... because need to load 32bit register, can convert these func for read 16bit value 2 time on 2 consecutive register than combine it to obtain 32bit register??
sometings like these:
Code:
float get_float_pin_val(QString nV, QString nVplus1){
char nHv[strlen(nV.toStdString().c_str()) + 1];
strcpy(nHv, nVplus1.toStdString().c_str());
char nHvplus1[strlen(nV.toStdString().c_str()) + 1];
strcpy(nHvplus1, nVplus1.toStdString().c_str());
hal_data_u *value;
hal_type_t type;
bool *con = nullptr;
char checkVal[16];
char checkVal1[16];
int r=hal_get_pin_value_by_name(nHv,&type,&value,con);
if(r!=0){
checkVal = {};
}
else {
checkVal = value->b;
}
int r1=hal_get_pin_value_by_name(nHvplus1,&type,&value,con);
if(r1!=0){
checkVal1 = {};
}
else {
checkVal1 = value->b;
}
/* usual combining code for checkVal1 & checkVal or L+H 16bit register*/
}
these can work or there are other way to obtain char value from bit? ... because value->f was unable to show in some way H part of my 16bit+16bit register .... but L part can see perfectly with value->f ... but only positive value.
