Are you able to measure the speed and compare it to using the CPU to do the same job?

@shapoco.net If you point me to the 3D renderer source code, I can tell you if I can optimize it with ESP32-S3 SIMD.

Testing...

I'm tempted to get it. I really like Sharp's Memory LCDs. The Sitronix LCD on that board isn't as fast or energy efficient as Sharp's, but it's close enough 😜

Did you create the front faceplate/case or did that come with it?

A bit of an exaggeration. If you're using RPIs for their original purpose then you don't necessarily need lots of RAM. If you're running multiple Docker environments or virtual OSs, then you should probably use a more powerful machine to begin with. My Zero2W handles almost all of my RPI projects.

Need more speed with your GIF animations on the ESP32-S3? I wrote some new SIMD code which speeds up playback another 20-25%

@snazzylabs.com Thanks for the shoutout in your latest video about TRMNL; it's nice to be appreciated for my work. You give me a little too much credit. These B/W EPDs are all basically identical hardware, but some are missing features in the controller firmware.

@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 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).

Do you know if the Bluetooth module can connect to BLE HID controllers (e.g. gamepads)?

TRMNL How custom look up tables (LUTs) increase performance for existing hardware.

trmnl.com/blog/custom-...

ish? Anything below 20C is too cold 😜

How about "The design error that condemned Linux GPIO to poor performance - treating it like a file to be placed somewhere in /dev"

Take a look in my bb_spi_lcd library in linux_io.inl. You'll see the GPIO direct access code which detects RPI 1/2/Zero/3/4 and adjusts things accordingly. No support for RPI5 since they changed the rules and hid the GPIO registers behind another chip :(

If you can run as sudo or mark the executable as root you can just directly manipulate the GPIO MMIO registers (not affected by currently loaded kernel drivers). I have code to do that too 😀. I wrote code to drive 8-bit parallel and QSPI displays like that.

I created one which uses GPIOD and runs on nearly any Linux SBC. It's currently in a private repo, but if you're interested, I'll send it to you.

This is made possible by creating custom LUTs (look up tables) for the update. By pushing mostly towards a single color and then doing a small push back for the grays, you can get 2-bit mode without all of the flashing.

Fast 4-gray LUT for SSD1677 EPDs YouTube video by tdfsoftware

Fast 2-bit (4 gray level) updates are now available in my bb_epaper library for both SSD16xx and UC81xx panels. I'll be adding/testing them slowly across devices:

New sensoria C5 PCB sent to fabrication today
Thanks to @fast-code-r-us.bsky.social for reviewing my schematics. This is the hardware sensor and reports visualiser from sensoria.cat projectPC

New release for mid February: 1.1 version of #Raspberry Pi (Zero2W and 4 versions) parallel Epaper monitor, great for monitoring of displaying your sensors information. Framerate around 12 frames per second. Designed in team with @fast-code-r-us.bsky.social
Anyone interested? Please RT & comment

This tiny pocket-friendly e-reader is packed with frustration and potential The Xteink X4 is small enough to slip into a shirt pocket.

New product taking shape - a #RaspberryPi AMOLED display HAT. It works on RPI Zero/1/2/3/4. Hi-res, super saturated colors and wide viewing angles. This one is 460x460 with capacitive touch. Excellent for gaming too (it's fast). Who's interested?

Palette settings are just coming online now. I'm implementing 3/4/6-color support too. All will work correctly soon...

True - late 70's was when LED watches started appearing. The first few home computers and electronic calculators/clocks became more prevalent soon after. The bulk of digital devices started appearing in the early 80s. My father and I built a Heathkit TV around that time too.
