Pin protection (yes, another thread)
I hope you don't mind me asking about this, I know there are other threads, and I did read through them, but I want to be sure I understand.   I have a UART open to the "...

Bootloader recommendation?
I know there are tons of good options but I'm rather new to bootloaders, and I'm afraid I'm suffering from a bit of choice paralysis.  Would anyone like to recommend a good...

Measuring temperature with 3.3V AREF? (issue with AREF stabilization)
I have a project where the hardware is designed such that the ADC is referenced to AVCC (3.3V).  AREF is connected to a 100nF cap to ground.   I wanted to add...

Suggested production programmer for AVRDUDE/ATmega328(p,b)?
We've been doing production programming for years with the MKII and custom scripts with AVRDUDE (mostly to burn a serial number automatically).  It worked great for a long...

Interfering interrupts: I2C inside timing interrupt, and USART
I have a project where I'm using I2C inside a timer interrupt to control external hardware, basically using the microcontroller (ATMEGA328pb @ 12MHz) as a feedback PID controller...

Atmega328pb serial number format?
I'm using the unique serial numbers in the atmega328pb to identify and track our products, but there are way more bytes (10) than I really need (2-3).     Anyone know...

Studio 7: recipe for target 'main.o' failed (different one!) - on blank project
I finally upgraded to Studio 7 to support the 328pb, but even a blank, default project fails to build.  This is really aggrivating.   Output:   ------ Build started...

Watchdog oscillator is wrong/faulty?
Here's a weird problem.   I noticed one device that was resetting spuriously, and I traced it to the watchdog.  The odd part is that it's timing out far too fast...

PWM Jitter added by ATMEGA328?
I'm using the ATMEGA328 to make some PWM waveforms, which I'd like to ensure are as low in phase noise as possible. There doesn't seem to be a spec on phase accuracy of PWM...

Difficulty with Fleury i2C - moving from ATTINY to ATMEGA
I have a project that's migrating from ATTINY to ATMEGA. They Fleury library worked great on my attiny, but there seems to be a timing problem when using the code on atmega....

Device suggestion: Flexible PWM (freq, duty variable?)
I would like to have 3 timers make a synchronized digital pattern; unfortunately I need to have control of both the frequency and duty cycle of each of them. Fastest one is about...

Sleep with watchdog off causes immediate reset?
I'm using an ATTINY88, and putting it to sleep until we receive a wakeup IR command (which is obviously an interrupt). Here's a code snippet: wdt_disable(); SMCR=0b00000101...
