- Comment on Is SPI just "slow"? 5 hours ago:
Thank you for the article it is really interesting. Always assumed it would already do just that but it does make sense considering the amount of Controller it has to support. Will be changing that anywhere it gets called often.

Thank you for your input. That does sound reasonable, currently i am closing and opening for each pixel i am setting. However the example code mine is based on also implemented away to set the cursor on an area. And i can then probably just provide more bytes than just two here. I will try this out later!
I don’t think mine is AVR based. It is the architecture of the CPU right? The datasheet says it has two Harvard Architecture Xtensa LX7 CPUs

Thank you for your reply. Sorry for forgetting the most important part about my setup. The Controller i am using, it is a NORA-W106 on a Arduino Nano ESP32 and according to its docs it has a clock speed of up to 240MHz, so i guess that would be enough depending on if that’s also base clock speed its running on right now…
NORA-W10 series modules have a dual-core system with two Harvard Architecture Xtensa LX7 CPUs operating at a maximum 240 MHz internal clock frequency.
Currently i set the SPI speed using
SPI.setClockDivider(SPI_CLOCK_DIV2);
Which would be 120MHz to my understanding assuming it runs at maximum speed. Too fast for SPI but that is not how it feels like. I will try some things out once i am back home especially as the method i use seems to be deprecated. - Submitted 16 hours ago to askelectronics@discuss.tchncs.de | 6 comments
- Comment on Fairphone announces the €599 Fairphone 6, with a 6.31" 120Hz LTPO OLED display, a Snapdragon 7s Gen 3 chip, and enhanced modularity with 12 swappable parts 16 hours ago:
Was really hoping to see a Fairphone 6a. Similar to the Google Pixel Series. Just a cheap version of it. I really don’t need 120Hz, OLED or “No Bezels” all i want is big battery and a headphone jack that is all.

Why is Sony 1000XM1 versions ahead of Apple?

I believe
browser.profiles.enabled
is a cool one you can enable now which isn’t on by default (But will be eventually) - Comment on Firefox 140 Brings Tab Unload, Custom Search & New ESR 3 days ago:
Sort of. I believe search engine providers actually have to create an extension to be listed in the setting.
- Comment on Windows 11 will soon let you know why your PC hardware sucks: Windows 11 will be able to explain why your PC needs more RAM and a better GPU. 3 months ago:
I was just wondering why tripple-a games don’t tell you that in the graphics options. Gave cyberpunk another chance with a newer pc and it was hard to dial in the right settings. It’s weird to me that they put a lot of effort into the games itself but don’t care how it will be experienced. Stating bottlenecks and recommendations for demanding settings would go along way i think.
