Handling of watchdog elapsed on ATxmega384C3
Hello.  I've asked another engineer here who is writing firmware for the ATxmega384C3 to add a watchdog to his design.  The embedded device is simple, it enables and...

Simplest way to extract flash from ATMega164P
Hello, we have developed firmware for a medical device on an ATMega164P.  It performs internal logging to flash.  We program the 164 using an AVRONE and IAR embedded...

Can I check the value of PC5/TDI with JTAGEN programmed on ATmega164?
Hello, it's been a long time since I've worked with the ATmegas, so I would like to confirm my read of the ATmega164 datasheet regarding using the JTAG pins as GPIO.   We are...

Design question: can you "get" too much?
I am reviewing some C code for an embedded device. My initial reaction is that I like the way he has organized it, sort of objected oriented, at least in this way: * all data is...

Main loop or RTOS?
Hey, freaks. We are having a protracted internal debate about whether an RTOS provides an advantage for our type of devices. There is some interest at my company in a micrium...

FLASH for logging?
Hey freaks. We have an old product that uses an AT mega 164 chip, and we need to add some diagnostic logging to it, basically storing data in non-volatile fashion so that if it...

How not to hammer EEPROM
So we're creating a device (on my trusty mega2560) with a control panel, and the user can change settings by pushing buttons. My project manager asked me to make the settings...
