nRF52 e-paper tag: reconstructing an undocumented display interface
nRF52 e-paper tag reconstructs control of an undocumented electronic shelf label with an nRF52832 board and SSD1675A-class panel. The repository records the pinout, 9-bit SPI connection, waveform-table layout and refresh behavior, and provides replacement Zephyr firmware plus a portable C99 display driver.
