Sure. When I wrote the corresponding code for Xmega - 1.5 years ago - Bascom did not have this support. Now single slope support exists for Xmega - and so life has become much easier. In any case I ag ...

Nice, Sergiu - thanks for sharing!

To Chris101: This is the most general solution which works with all receivers. Depending how the servo pulses are generated by the receiver (one after the other, ...

Oh, I forgot to mention this: The gyros have a Vref output, 1.? V. I would just feed Vref to a voltage divider, e.g. two 10k resistors:

Vref---R---ADC0---R---GND. Have ADC0 connected to ADC0 and AD ...

Per:

Think about promoting Bascom AND having your forum!
Why not putting the GA into an application note? You may have to live with a (relative) lack of interest for some time - but on the long ru ...

Hmm, if you run the M2560 at 5V and "full" speed (>8Mhz), then the calculation changes. Depending on how you have configured the ADC, 10 bit resolution could apply to 5V, viz. about 5 mV per LSB. W ...

Hello Matrixx,

your calculation looks right to me. I remember a gyro-gain of 0.92. So if you have a difference of 15 ADC units (289-274) this is roughly equivalent to 13.x Deg/sec.

I did the "ma ...

Hello Matrixx,

the gyro raw signals look noisy and appear a bit "digitized" indeed. I wonder how the integrated raw signal will look here. If you do a "manual integration" in Excell - just by plott ...

Thanks Mark!
Also thanks for 2060!!!
Serial buffering by DMA was on my personal wishlist long time (MAK3 has prepared an example for it).
