+# Migrating Lily58 to use split_common
+
+[#6260](https://github.com/qmk/qmk_firmware/pull/6260) Modifies the default firmware for Lily58 to use the `split_common` library, instead of including and depending on its own set of libraries for the following functionality:
+- SSD1306 display
+- i2c for OLED
+- Serial Communication
+
+This allows current lily58 firmware to advance with updates to the `split_common` library, which is shared with many other split keyboards.
+
+## To migrate existing Lily58 firmware:
+
+[Changes to `config.h`](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-445ac369c8717dcd6fc6fc3630836fc1):
+- Remove `#define SSD1306OLED` from config.h
+
+
+[Changes to `keymap.c`](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7):
+- Find/Replace each instance of `#ifdef SSD1306OLED` with `#ifdef OLED_DRIVER_ENABLE`
+- The following changes are for compatibility with the OLED driver. If you don't use the OLED driver you may safely delete [this section](https://github.com/qmk/qmk_firmware/blob/e6b9980bd45c186f7360df68c24b6e05a80c10dc/keyboards/lily58/keymaps/default/keymap.c#L144-L190)
+- Alternatively, if you did not change the OLED code from that in `default`, you may find it easier to simply copy the [relevant section](https://github.com/qmk/qmk_firmware/blob/4ac310668501ae6786c711ecc8f01f62ddaa1c0b/keyboards/lily58/keymaps/default/keymap.c#L138-L172). Otherwise, the changes you need to make are as follows (sample change [here](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7R138-R173))
+- [Remove](https://github.com/qmk/qmk_firmware/pull/6260/files#diff-20943ea59856e9bdf3d99ecb2eee40b7L138-L141) the block
+```c
+#ifdef SSD1306OLED	
+  iota_gfx_init(!has_usb());   // turns on the display	
+#endif
+```
+- Within the block bounded by `#ifdef OLED_DRIVER_ENABLE` and `#endif // OLED_DRIVER_ENABLE`, add the following block to ensure that your two OLEDs are rotated correctly across the left and right sides:
+```c
+oled_rotation_t oled_init_user(oled_rotation_t rotation) {
+  if (!is_keyboard_master())
+    return OLED_ROTATION_180;  // flips the display 180 degrees if offhand
+  return rotation;
+}
+```
+- Remove the functions `matrix_scan_user`, `matrix_update` and `iota_gfx_task_user`
+- Find/Replace `matrix_render_user(struct CharacterMatrix *matrix)` with `iota_gfx_task_user(void)`
+- Find/Replace `is_master` with `is_keyboard_master()`
+- For each instance of `matrix_write_ln(matrix, display_fn())`, rewrite it as `oled_write_ln(read_layer_state(), false);`
+- For each instance of `matrix_write(matrix, read_logo());`, replace with `oled_write(read_logo(), false);`
