Passive NFC ink screen driver board

# Introduction
In the early years, there was a pit of passive nfc ink screen [battery-less NFC ink screen] (https://oshwhub.com/ludas/nfctag_v4). It was a spur-of-the-moment product with low usability, and the screen only supported one model. Common 2.7-inch weird screen (not compatible with 24pin universal serial port screens on the market). Unexpectedly, there are quite a lot of people who like this thing, and I still get private messages from time to time urging TAT updates. This time I took advantage of some time at the end of the year to make a new version, which uses a universal 24p interface. Because of the size of the antenna, the measured maximum supported refresh is 2.9 inches (4.2 inches will be powered off if the refresh cannot be completed). When I have time (...) I will update the PCB with a larger antenna.

The attachment of the food instructions is the firmware and Android app of stm32l011, which currently only supports the 2.13-inch screen of the SSD driver IC (resolution 122 x 250) See the figure for the modulo-taking method (although the screen has a resolution of 122, the image (I know... the app is really being written...)
