Scrolling Bitmaps
If you look at the source code, they appear to do like anyone else where you eventually end up in a draw pixel type function.   This draw pixel function will just return if...

Using HDC2080 with I2C in ATmega4809 with UPDI and Atmel Studio
You will need to add the following option to your build options- -std=c++17   If the compiler is not capable (most likely is), then -std=c++14 will also work I think.  ...

Mega4809 and CRC
>It appears that this peripheral is only for use in generating a CRC for the flash   You are in charge of generating the crc, it simply checks if the flash range you...

Scrolling Bitmaps
Start out with something minimal that you can wrap your mind around, and it will scale up.   A 3x3 bitmap is a good start- https://godbolt.org/z/7LxzLU   There may be a...

Using HDC2080 with I2C in ATmega4809 with UPDI and Atmel Studio
I tried to read the arduino twi library code to figure out what may be happening, but kind of lost interest in the puzzle.   If you want to test the sensor out some more...

Timekeeping - High Level ?
As a start, I think I would just find out how good the mega4809 is with a standard 32k crystal. Use the precision temp ic to set the calibration register value on some regular...

Using HDC2080 with I2C in ATmega4809 with UPDI and Atmel Studio
I have a couple things wrong in the added HD code, I'll try again. I'll test with the tmp117 before I show it this time.   updated C version- https://godbolt.org/z/...

Using HDC2080 with I2C in ATmega4809 with UPDI and Atmel Studio
I don't use Atmel Studio, so can't speak to how to operate that software (and can't really sift through arduino easily).   This is a slight modification of something I posted...

Atmega1608 won't execute USART
I would go simple, create a single file like below, and either just get the tx pin to toggle or send something-   https://godbolt.org/z/rAZC_b   Now it may be that just...

Attiny402 - RTC problems
>RTC module is configured as perodic interrupt with an period of CYC32   When your cpu clock is 32k, and you want an interrupt every CYC32 (happens to be 32 cpu clocks if...

Timekeeping - High Level ?
I think I'm just re-wording the last post (or I guess now its #11)-   When the time is updated with a precise value, just log the event as a time update (with the new...

Off to a rough start... AVR128DA48
>I'm not sure how they map the other 32k flash segments into data memory space, but I assume they are using rampz to choose the 32k segment.   Looks like I was wrong,...
