"Anyway,on my APM 2.0 board who been thru all kind of malesting but still alive I do not have voltage on eternal compass i2c conector but I do have perfect 3,3V on connector next to it...does this mean that SCL and SDA conector are dead or I can…"
"I think I know what you mean Start the Arduino IDE(I used 1.0.5) with your APM hooked up (and with the correct settings: comport/arduino). Now go to the menue files/examples/eeprom/eeprom_clear and upload that sketch. Done. uploaded…"
"Hm,Rainer as you can see from post above I did erase command in terminal screen....also I did factory reset with reset command in terminal...
I can arm and disarm,PPM Graupner,ppm encoder updated both on APM and RX
I newer used arduino softwere,ist…"
"No,HengLee motors you have are perfect candidate to swing 18 or 20 inch prop on 4 S batt..a bit heavy they are but will be ok..6-kg hexacopter should fly that way longer than 15 inch on 6S...buy just one big 18 and 20 prop and do some testing on 4s"
"Huges I will post your thoughts here again,very well written
Why is this so important ?
-Voltage and current measurements are a critical for a safe flight (cf the number of accidents/crashes happening because of bad batteries and/or…"
Hello Emin, What is your application? I learned to read ppmsum using the pin change interrupt
that is only on pin 8. Outputs (pwm)are toggled directly from within the ISR. I used it for a head tracker, and a gimbal stabilizer with the imu v3. Only one 16 bit timer on the 328p and it does everything as time related with interupts.
