+# 4D Systems gen4-ESP32-70CT (LVGL MicroPython)
+
+This configuration targets the 4D Systems gen4-ESP32-70CT (800x480 capacitive touch).
+
+- Board info: `display_configs/Gen4-ESP32-70CT/board.json`
+- TOML config: `display_configs/Gen4-ESP32-70CT/Gen4-ESP32-70CT.toml`
+
+## Build
+
+Run from the repository root:
+
+```bash
+python make.py esp32 clean BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=SPIRAM_OCT --toml=display_configs/Gen4-ESP32-70CT/Gen4-ESP32-70CT.toml INDEV=ft5x46
+```
+
+## Build + Flash in one step
+
+If the board is connected, you can build and flash directly:
+
+```bash
+python3 make.py esp32 --toml=display_configs/Gen4-ESP32-70CT/Gen4-ESP32-70CT.toml deploy
+```
+
+Optional explicit serial settings:
+
+```bash
+python3 make.py esp32 --toml=display_configs/Gen4-ESP32-70CT/Gen4-ESP32-70CT.toml PORT=/dev/ttyACM0 BAUD=921600 deploy
+```
+
+Notes:
+- `PORT` can be omitted. The build script will try to auto-detect the ESP32 port.
+- If multiple ESP32 devices are connected, the script will ask which one to flash.
+
+## Flash later (manual)
+
+If you build without `deploy`, the script prints an exact flash command at the end under:
+
+- `To flash firmware:`
+
+Run that printed command to flash later.
+
+## Common issue
+
+Do not use `--board-config` with GNU make. For this project, board presets are selected with `--toml=...`.
+
+## Troubleshooting (unstable / rolling image)
+
+If the picture looks unstable (for example text appears to "run through" the panel), this is usually RGB timing related.
+
+- This preset uses a conservative pixel clock (`freq = 10000000`) for better signal stability on ESP32-S3 RGB panels.
+- This preset defaults to `pclk_active_low = false`. If your panel is still unstable, toggle `pclk_active_low` in `Gen4-ESP32-70CT.toml` (`true` <-> `false`) and rebuild.
+
+Rebuild command:
+
+```bash
+python make.py esp32 clean BOARD=ESP32_GENERIC_S3 BOARD_VARIANT=SPIRAM_OCT --toml=display_configs/Gen4-ESP32-70CT/Gen4-ESP32-70CT.toml INDEV=ft5x46
+```
