Hi guys I'm having trouble to get this code works. I want to multiply and divide and I use the following code: valor1=ADC0; valor1=valor1*2; valor1=valor1*12; valor1=valor1/5; valor1=valor1/4095; with valor1 as float but the variable valor1 never is the right number. what is wrong?? can be another way to do this multiplication: valor1*2*2.42/4095 Thanks
"When I read the adc I read 925 and 924 values but when I don't put brakpoints the calculation is bad." Erik's point is: how do you know that it's the calculation that's bad? How do you know that you're not just reading a bad value from the ADC? As Erik said, noise could cause this. You could also have a timing problem, such that your ADC reading only works when you delay the code with a breakpoint! You might also have a faulty interrupt that is corrupting stuff... You need to save the actual value read from the ADC, and include that in your diagnostic printout.
Thanks guys but the problem was a delay between tha adc0 refresh value. I resolve the problem thanks
