ADC voltage range on ATmega128RFA1?
I badly worded my OP . . . lets start over! What I want to have is a 3.3V ADC. If I follow the application circuit it gives me a 1.8V ADC range. If I set AREF to 3.3V using an...

ATmega128RFA1 wireless bootloader?
bobgardner and stevech, you misunderstood my question . . . I never said anything about a factory pre-installing a bootloader =P

danni's bootloader for atmega1284p [solved - sram big!]
I ran into this same problem, but for another chip. If I reduce the SRAM_SIZE from 16384 to 8192, it'll give me this error: "The contents of the objectfile exceeds the maximum...

ATmega128RFA1 state transition detection issue
OK, I figured it out, mostly. I wrongly assumed there was a single register I could read from to access the buffer. The solution is to read from each individual byte in the buffer...

ATmega128RFA1 state transition detection issue
I've discovered something . . . Whatever uint8_t data equals, that determines frame_length. For example, if data is 8, then frame_length ends up as 8. It's obvious I'm not writing...

ATmega128RFA1 state transition detection issue
UPDATE Now that I have RX working, I tried my code back on my own custom boards again, and suddenly the CRC error disappears. Turns out the SF boards are total crap lol . . . That...

ATmega128RFA1 state transition detection issue
I figured out why RSSI wasn't working before . . . apparently it can only be read after an RX_START interrupt and before an RX_END interrupt. No luck for anything else yet . . .

ATmega128RFA1 state transition detection issue
Ok thanks! Really helped. I get the 2Hz pin flipping on my Sparkfun boards (which I assume would only happen if the transmission is detected, right?). uracolix, a quick favor...

ATmega128RFA1 state transition detection issue
Thanks dl8dtl I'm using both the Sparkfun ATmega128rfa1 dev board, and a custom board I made. Same issue on both. You mentioned the diagradio test. I wasn't sure how to do it, and...

ATmega128RFA1 state transition detection issue
Thanks =) Emailed. Yeap, the wireless was kept as all one file. I also included my main file just so you can see the order that I'm calling the wireless functions.
