AVR 128da curiosity nano power supply issue
  So you must:   1) Wire up the Voff connection pin 2) Plug board into USB/PC     ..(this must be done before step 3) 3) Turn on the board...

AVR 128da curiosity nano power supply issue
I tried it again and got it working on the external power supply.  It seems to be an issue with the order of things.  The switch that shuts down the internal target...

AVR 128da curiosity nano power supply issue
I was using an external 5v supply.  I did have the gnd connected.  The schematic block diagram in the user manual shows the level converter being powered on the other...

mega4808 clock source
Nice to know.  I wonder if this works with the AVRxxxDAxx series?   I have another question about clock source.  These chips seem to have a PLL, but it can only be...

Migrating to AVR, lots of PIC18 background
Is that part supported in avr-gcc? Yes as AVR DA-series is an existing XMEGA computer architecture.   Where is the ioxxxx.h files for the DA parts?  Couldn't find...

Migrating to AVR, lots of PIC18 background
I also feed the AVCC through an rf choke, 100-1000uh, but only if I'm actually using the A/D, then just a bypass cap.

Need to generate PWM waveform on 0C3B of atmega328PB
That did it.  I set OC3B high (portd bit high and got a 31khz wave form.

Need to generate PWM waveform on 0C3B of atmega328PB
No output from pin 0C3B with this code, pin stays low,  DDRD |= (1 << 2); //set OC3B as output TCCR3A = (1 << COM3B1) | ( 1 << WGM30); //set FPWM mode 5 top...

Need to generate PWM waveform on 0C3B of atmega328PB
So far no.  I don't think you can set the ICR if you select the 8,9, or 10 bit fast pwm mode, you're then stuck with TOP values of 256, 512, or 1024.    This means...

Need to generate PWM waveform on 0C3B of atmega328PB
It looks like that's what I was doing (if I leave off the interrupt mask setting)   TCCR3A = (1 << COM3B1) | ( 1 << WGM30); //set FPWM mode 5 top = 0xFF output on...

Need to generate PWM waveform on 0C3B of atmega328PB
I'm stuck with the atmega328pb, need all the pins, hence running with the internal RC clock.  I can clear the divide by 8 clock fuse and run it at 8mhz, and I don't need...
