Hi guys, @Pilius already made a question like the one I'll do here but he had no response.
At the moment I'm doing a project with MiCS-6814 and I would like to get your help, please. As it was asked before, what are those values and how do I get them?
//-1.552, 1.622, the expression.. Where does this expression come? I know there's a graph on datasheet but how do you relate it?
c = pow(ratio1, -1.552)*1.622;
//The ratio is Rs/R0? Where does this expression come from?
ratio1 = (float)An_1/(float)A0_1*(1023.0-A0_1)/(1023.0-An_1);
//A0_1 is equal to what? I know where it comes from but what does it represent?
int A0_1 = get_addr_dta(6, ADDR_USER_ADC_CO);
//An_1 is equal to what? I know where it comes from but what does it represent?
int An_1 = get_addr_dta(CH_VALUE_CO);
Sorry for so many repetitive questions but I really need to know that in order to present my project...
Thank you :)
