New library coming up from our new Firmware with C5
github.com/martinberlin...
A very simple way to instantiate I2C bus in IDF that you can just use for every peripheral on esp-idf
(New idf won't cope anymore with legacy i2c_driver_install instantiation)

@fasani.bsky.social created something unexpected - a parallel Eink PCB (Sensoria) based on the ESP32-C5. This chip is faster than the ESP32-S3 and has 5GHz WiFi. Now added to my FastEPD library.

ESPHome e-paper without flicker
ESPHome e-paper without flicker YouTube video by tdfsoftware

**New** I created an #ESPHome display component wrapper for my bb_epaper library. This means that using e-paper on ESPHome devices just got a lot easier. For IoT devices with integrated displays (e.g. this one), 1 line of yaml defines it! (plus flicker-free updates).

PCB designed this time only for the 10.3" eink display. Compatible #TRMNL X. With a new concept of ultra deep sleep that was actually conceived by Jonas team but optionally also compatible with normal deep sleep. In ultra, everything is OFF, 1.5uA consumption

This is a good proof that in HI-res like this one sometimes a photo shown in 1-bit resolution looks better than with 16 grams

Very strange accident. The train was quite new (Less than 4 years old) The railways recently renovated with a huge investment and there were no curves. What could have possibly go wrong?

By the way 4 bit and 2-bit more work really bad for now in Terminal X, will later add some photos, left it as before in 1-bit

That according to the web settings was 1 bit. tried to update it to 16 grays just to see the change but it looks good enough using only 1 bit per pixel

@fast-code-r-us.bsky.social the photos look very good. Is that just 4 grays with dithering or is in fact using the 16 grays of the parallel Eink?

It could be of course be launched locally. But we are hoping to scale in users and is not sime you want to host at home.
