About this project
About this project
A C driver for the ET014TT1 / GDEP014TT1 panel: 128×296 native, a 2bpp framebuffer holding black, dark grey, light grey and white, drawing primitives, scalable dot-matrix ASCII and four rotations. The ESP32-S3 port targets ESP-IDF 5.5 at 240 MHz on an exclusively owned SPI2 bus, and pin assignments for PWRON through MISO span GPIO 4 to 13. Default page updates use GC4; a full INIT plus GC4 took about 3.55 seconds in 121 + 31 frames at 32 °C on the sample. Images arrive as fixed 9472-byte frames over a CRC32-checked serial link. Vendor waveform data is bundled but not covered by the MIT licence, and there is no built-in Chinese font.
