Why UART data is getting corrupted?
If this is in a mall it's also possible you're picking up transients from adjacent high-voltage stuff. I made a DMX receiver and saw random 17V spikes on one of the exposed IO -...

AVR32 avr32program error DFU ISP
UPDATE: Another issue to keep in mind regards the isp_cfg.bin file that you can generate when you run the configuration word script (isp_cfg.sh): If you give the script a filename...

AVR32 avr32program error DFU ISP
Ohhhhhhh, I was using the wrong -c option! Per the "avr32program help program" command: Quote: -c, --clock Specify CPU clock source to use when programming (support limited to...

Make a .bin file
My apologies, that was a rather pretentious claim of mine! So it seems like I have 2 options: 1. Use PROGMEM instead of EEPROM for NVRAM parameter storage. I would rather use...

Make a .bin file
What a prompt reply, thanks! Ok, I understand what you're saying about going from hex to binary, and about the separated memory spaces. I guess I'm curious about whether or not...

help needed with serial comms/dmx-512 and USART on Atmega8
Yes, I am using the internal RC oscillator at 8MHz (set via fuses). You are correct in that USART timing is a whole lot more accurate with an external clock source, but I think...

help needed with serial comms/dmx-512 and USART on Atmega8
I'm using WinAVR, downloaded sometime late last year. Do you have an example snippet of code for how you check for a break using 250K, 8N2? Placing debug LEDs on my board, it...

help needed with serial comms/dmx-512 and USART on Atmega8
Gyah, I just cannot get this code to work. I am using a DMX console that spits out all 512 data slots at 44Hz which is per the standard. I am using 250Kbps (ubrr = 1 @ 8MHz), 9N1...
