This is a MIPI-DSI and SPI touch controller; you can use any development board with these interfaces to drive it.

Not the first one, they actually forgot about their own product.

The internal components are very simple, and it comes with a 4GB TF card. The main controller is a Jieli-AC6956, which may be able to run custom firmware.

A $5 (reflective) LCD device with 300x400 resolution and a touchscreen, compared to Sharp's memory LCD.

As you know, other desktop environments have very poor support for touchscreens.

In the past, this required a lot of fundamental knowledge; you needed to be in a related industry. Now, all you need is AI.

Porting Debian to my voice recorder

Of course, this isn't the whole truth; the key is the impact on tcon.

The SPI interface inherently limits its ability to refresh at high speeds; the only way to improve speed is to reduce the number of colors and grayscale values.

Meta deserves praise for this; they are willing to continue to allocate resources to hardware development. In contrast, most manufacturers rarely make changes after product launch.

TWRP on an eink , I created this very "ugly" UI.

They did this intentionally; they wrote the code in C, compiled it to binary, and then converted it to assembly.

This $50 e-ink tablet, discarded by an educational institution, uses the RK3566, almost identical to the #PineNote , and can easily run Linux. The Eink driver is closed-source (only assembly code is provided), and I rebuilt it using AI. github.com/iocodev/kernel-4.…

“DA ESP32-C3”

edk2 has been around for many years and is very mature on Qualcomm platforms, but porting it to other ARM platforms requires a lot of work.

Of course it's ARM.

This USB passthrough feature is great, making it easy to use USB tools on Linux, but sometimes it can lead to zombie devices.

Deepseek v4 Pro + ClaudeCode TUI

Unisoc is easy to port to the mainline, but there aren't many references available right now.
