@WAlmasarani @PCBWayOfficial Happy New Year 🥳 & a toast to our new 2024🥂
@WAlmasarani Here's to more collaboration and success in 2024! 🚀
epdiy v7 tests using LCD bus at 22 MHz and S3 at max speed
Testing epdiy V7 boards Last one for sale on @tindie just search 'epdiy' @Lukas_Vision11 has one too
Live on @tindie tindie.com/products/fasan… last 2 units available! Next production attempt end of August
I have the idea to measure temperature 🌡️ with DS3231 and build a "death ⌚" that will stop updating the ePaper when temperature gets under certain level marking the exact hour of your death This could help solve crimes and make life a bit more interesting
Submitted last remaining unit of epdiy V7 to @tindie approval. Still need to upload some tech details like BOM and more details
#stackoverflow builds their own AI and it seems it will be integrated in #VSCode with a plug-in Sounds interesting, right? Would you try it out?
here we go: 2021 ESP32-Sx Octal Flash/PSRAM WROVER Modul 2023 sized to WROOM, we are pincompatible, have Octal Flash, Octal Psram outside SiP. also a SOIC/WSON-8 in da BGA24 footprint combined - how cool is that John? *WoWZa* #ESPRESSIF @EspressifSystem x.com/embeddedhome/s…
desk #leaks (march 2021) who owns this WROOM Octal Modul ? #PSRAM #OCTAL hey @EspressifSystem if you not bring it to the market since ready 3 years now i will build it and name it: ESP32-S3-WoWZa-N256R256 in WROOM-2 design 😋 🫵You had your chance ℹ️💁 esp32.com/viewtopic.php?…
If someone is interested on trying Sharp memory LCDs with @EspressifSystem IDF framework github.com/martinberlin/s… Prepared there a repository that is very easy to test and should work with 128x128 and bigger models Just do a: git clone URL --recursive To fetch components
New challenge for next days: github.com/martinberlin/s… Will try to make an RTC watch with a small Sharp LCD to be powered at least 6 days with a battery lowering the speed of CPU and sleeping after 1 or 2 minutes inactivity
@WAlmasarani @adafruit You have here a list of around 10 supported models: github.com/martinberlin/c… One of the DKE (800x480 Black/Red) And I guess you have the knowledge now to add new ones quite easily after some testing
New release of CalEPD #epaper component github.com/martinberlin/C… Includes a new DKE model added by @WAlmasarani plus ESP-IDF 5 updates. It should build smoothly and get out of the way, to let you build UX in displays, and show the information using @adafruit GFX
New LCD segment watch (left) 6.5€ bought in Berlin flea market
its enough 16 mb flash since we can only mount as MTD-ROM -we use for files later sd card or nand but push the psram up to the limit on availability psram .. just in time 256mbit, in the pipe sample state also 512mbit possible also 1024 after request. give us psram - please :)))
Very nice work Ward. I hope some developers will follow the tutorial and make their own screen renders for their desktops!
youtu.be/7Sal9Ii7H2U Epaper board tutorial using Cale-IDF library created by @martinfasani is on Useful Electronics #epaper #eink #candledisplay #esp23 #microcontroller #bitcointrade #bitcoinchart #embeddedsystems #embedded
This time the dynamic frequency CPU part using ESP-IDF PM is working: github.com/martinberlin/s… @WAlmasarani this could be useful also for epaper clocks since reducing ESP32 freq to 10 Mhz reduces a lot consumption so your battery will last much longer. But no WiFi at 10Mhz 🛜
And sorry it’s Ward, not Wald. I think got confused since I have a friend called @walditocom that is the tallest man of Mallorca ;)
