Xmega with 18 PWM outputs?
From AVR support Quote: Dear Bjorn, XMEGA devices has timer that features maximum four compare channels per timer. This means, using a single timer you can generate four PWM...

Xmega with 18 PWM outputs?
Software is not an option. Will keep the AVR busy with many other tasks as well :) The PWM will be used to dim LEDS, need to be above 100 Hz to experience it flicker free.

Gravity sensor
John, thanks for the kind offer. But I'll pass as I would need 1k-2k to cover my needs. /Bjorn

Gravity sensor
Thanks for all the quick replies. Brutte: How would the light sensor logic work? Assume that light direction is up? mckeemj: Well, the cheaper the better :-) Analogs devices look...

Gravity sensor
Realizing now that a normal acceleration sensor could be enough? Any tips on ICs to use? /Bjorn

Cannot init external 32 kHz crystal on ATxmega256A3BU
Problem solved! Module Access Enable bit must be set first: VBAT.CTRL = VBAT_ACCEN_bm; Not obvious in the documentation. Hope it helps anyone with the same problem. Kind...

Johan: None of the wristbands were collected at the exits. Instead they were put in impact mode. The wristband would then light up for a few seconds after being shaken. I will of...

Alternative to Wiznet W5200
Hi all, Just an update on this topic. We got the W5200 working now. I had the PWRN (power down) pin connected to 3V3 instead of GND. Stupid mistake but to my defence it does seem...

Alternative to Wiznet W5200
Hi Nard, We have several designs running the Xmega family and feel quite comfortable with them. What really puzzles me is that we've recorded all SPI traffic with a digital...
