hi, i'm a little bit stucked with that sensor, i haven't understood so well how to measure the angle with the simplest circuit (only the current flipping and two lines going to the adc after pre amplifying ...

something like the scheme inside the cmps03 module...

someone has any experience with that sensors Huh


best regards

Interested and hopefully helpful in: DC brushed motor control (mainly R/C - PPM/PWM), analog audio, PIC (mikrobasic PRO). Feel free to ask, and if I can, I will help. But only on forum topics, any started private conversation will continue in a public topic.

yes i did but the calculation of angle from the 2 voltages from the two channels is still not clear ...  clock signal and simplified circuit is already ok to me, just a pwm 1khz with low low duty cycle ///
