Yours or mine? 😀

Have you tested use of the mesh network to get messages across multiple hops? I've been reading about many users finding that the peer-to-peer aspect works as it should, but if you need to get messages across other people's devices, it basically doesn't work.

Maybe you want to choose a different virtual Sitronix controller. The ST7789 (and all software written for it) assumes a max resolution of 240x320. What is your ultimate goal? To drive more complex LCDs from something like MicroPython?

You can use an ESP32-S3 for that. Would the S3 w/PSRAM cost less than the LT7680?

That's a good way of putting it. Some modern embedded devices feel a lot like computers from the 70s/80s (total control over the SW+HW). This is probably why I like writing Linux CLI programs - A tiny bit of C code can do actual work on modern+old HW without walled gardens or popup ads.

That sounds like the mirror version of "tech support purposely delays responding to queries to allow time for the customer to figure it out for themselves" 😀

GitHub - bitbank2/OneBitDisplay: A full featured Arduino display library for 1-bit per pixel OLED, LCD and e-paper displays A full featured Arduino display library for 1-bit per pixel OLED, LCD and e-paper displays - bitbank2/OneBitDisplay

I did a major rewrite of my OneBitDisplay library. I removed all support of e-paper displays since that's now in bb_epaper, and I added my updated compressed font+bitmap support. I'm still working on documentation and examples, but you can give it a try now if you like:

Did you eat any eggplant or tomatoes/sauce? As strange as it sounds, some people are sensitive to the chemicals in nightshade plants and it creates inflammation in the joints. It can last 2-4 days after you stop eating it.

Building a Better Bitmap (font system) Intro There is a common need in the computer world to display text on dot-addressable displays. As with everything else, there are many ways...

The People have rights against the powerful. That is what America is about It’s notable that these words keep getting repeated — almost like those “unalienable” rights of “life, liberty, and pursuit of happiness” are really important. The Reconstruction Amendments — the 13th, 14th, and 15th — weave together the threads of the Constitution, the Bill of Rights, and the Declaration of Independence. They were a critical update, you might say, one that patched the Founders’ system-destroying error of perpetuating slavery while simultaneously declaring all men to be created equal. The 14th acknowledges that states, too, can be tyrants. Whether it is George III, the feds, or the slave-holding antebellum states, the People have rights against the powerful. That is what America is about.

America is a system and that system has crashed. @lopatto.bsky.social and @sarahjeong.bsky.social don’t mince words here www.theverge.com/policy/69730...

Hard to tell from the photo, but what are the measurements of the whole thing? Is it made of painted plywood?

Give them a bonus for not defining any API. This causes the chaos that every BLE chip vendor makes their own incompatible mess.

The funny thing is that there actually is at least 1 ESP32 with a DFU bootloader -> the Arduino Nano ESP32.

I think the phrase you're looking for is -
"Do something outrageously awful... to someone else!"
This is the general theme of that cult.

In our attempts to curb crime in America, have we misunderstood the problem? Malcolm Gladwell explores the motivations behind violent acts.

ST7789 is an IPS LCD. Good viewing angles, bright backlight. The only upgrade from there is AMOLED. Higher resolution, higher cost, but look even better. Something like this (I have this one and 5 other small AMOLED/ESP32-S3 products similar to this):

Travel Forecast for Thursday as generated by the Weather Star 4000+ emulator. At the bottom my humidity of 7% and dew point of 21°F. Everything is washed out like an analog NTSC television image, which I did by overlaying shaderglass with an NTSC shader.

Did you know someone reverse-engineered the Weather Channel computer system from the 80s/90s and now you can generate your own private weather channel for your location?

I created breakout boards to easily connect the inexpensive OLEDs and 'blue' ST7789 PCBs to Xiao, Nano & Feather. Inexpensive and easy to use. I also like the ESP32 boards with built in displays.
