According to `helix/rev2/keymaps/fraanrosi/readme.md`, this keymap should be compiled with the following command:

```
make helix/rev2/under:fraanrosi
```

Therefore, when compiling all helix keymaps with the following command, an error occurs when compiling `fraanrosi`.

```
make helix:all
```

Therefore, add `LED_UNDERGLOW_ENABLE = yes` to `keymaps/fraanrosi/rules.mk` to suppress the error.

* Extensible split data sync capability through transactions.

- Split common transport has been split up between the transport layer
  and data layer.
- Split "transactions" model used, with convergence between I2C and
  serial data definitions.
- Slave matrix "generation count" is used to determine if the full slave
  matrix needs to be retrieved.
- Encoders get the same "generation count" treatment.
- All other blocks of data are synchronised when a change is detected.
- All transmissions have a globally-configurable deadline before a
  transmission is forced (`FORCED_SYNC_THROTTLE_MS`, default 100ms).
- Added atomicity for all core-synced data, preventing partial updates
- Added retries to AVR i2c_master's i2c_start, to minimise the number of
  failed transactions when interrupts are disabled on the slave due to
  atomicity checks.
- Some keyboards have had slight modifications made in order to ensure
  that they still build due to firmware size restrictions.

* Fixup LED_MATRIX compile.

* Parameterise ERROR_DISCONNECT_COUNT.

* cleanup keyboards/helix/{rev2|rev3_5rows}/keymaps/five_rows

* Made the layout data easier to read.
  * helix/rev2/keymaps/five_rows/keymap.c
  * helix/rev3_5rows/keymaps/five_rows/keymap.c

* The following two were made the same.
  * keymaps/five_rows/config.h
  * keymaps/five_rows/oled_display.c

The binary of the compilation result has not changed.

* update keyboards/helix/rev2/keymaps/five_rows/rules.mk

KEYBOARD_LOCAL_FEATURES_MK was moved to the end.

* add '#define DISABLE_SYNC_TIMER' into helix/rev3_5rows/keymaps/five_rows/config.h

The sync timer features worsen the matrix scan rate of the Helix keyboard. I'm not sure if it makes sense to have sync timer features enabled on the Helix keyboard. So in my keymap I disable this.

* Latam version of Helix/rev2/back

 . Latam adaptation of keymap(whit "ñ")
 . 3 layers (Qwerty, Lower, Raise)
 . Underglow light changes while pressing Lower(BLUE) and  Raise(RED), then it returns to prior mode.

(cherry picked from commit 974be35011)

* Se añade Keymap.

* Agrego un pdf preliminar del mapeo y reubico el keymap a carpeta correspondiente.

* Ajustes en mapeo para simplificar.
Agrego Mark Down con mapeo.
Creo carpeta "layers mapping"  para guardar lo correspondiente a mapeo.

* Update keymap.md

* Rename keymap.md to readme.md

* Organización en general y cambio de configuración de "back" a "under"(que era la que correspondía).
.Ahora los leds underglow responden mejor.

* -Se agrega indicador rgb para el bloq mayús.
-Se agrega manejo del rgb_tog.

Apparently VSCode does not like unicode, I didn't actually edit these lines, so it must have been automatic... :(

- The difference with the original let's split's serial.c
  - It's high-speed about 4 times.
  - Stable bi-directional data transfer. (Helix need master to slave transfer)
  - serial.h was divided 2 files, serial_config.h and sereial.h
  - With multiple types of transaction support, communication contents can be optimized. (NEW flexible API)

- USE OLD Simple APIs (compatible with let's split serial.c)
  - files :
    - serial_config.h -- hardware configuration (need include by config.h)
    - serial.c/serial.h -- serial communication

- USE NEW flexible APIs. (Support multi-type transaction function.)
  serial.c was divided into 2 layers, split_scom.c and serial.c.
  The upper layer split_scomm.c is called from matrix.c.
  The lower layer serial.c accesses the hardware.
  - files
    - split_scomm.c -- communication buffer is defined in here. call by matrix.c.
    - split_scomm.h -- buffer size is defined in here. include by matrix.c, split_util.c
    - serial_config.h -- hardware configuration (need include by config.h)
      To use the NEW API, specify #define SERIAL_USE_MULTI_TRANSACTION
    - serial.c/serial.h -- serial communication lower layer

- NEW APIs for serial.c / serial.h (The lower layer)
  // Soft Serial Transaction Descriptor
  typedef struct _SSTD_t  {
      uint8_t *status;
      uint8_t initiator2target_buffer_size;
      uint8_t *initiator2target_buffer;
      uint8_t target2initiator_buffer_size;
      uint8_t *target2initiator_buffer;
  } SSTD_t;

  // initiator is transaction start side
  void soft_serial_initiator_init(SSTD_t *sstd_table);
  // target is interrupt accept side
  void soft_serial_target_init(SSTD_t *sstd_table);
  int soft_serial_transaction(int sstd_index);
  int soft_serial_get_and_clean_target_status(int sstd_index);

- NEW APIs for split_scomm.c / split_scomm.h (The upper layer)
   move from old serial.c the following buffer and functions
     serial_slave_buffer[]
     serial_master_buffer[]
     void serial_master_init(void)
     void serial_slave_init(void)
     int serial_update_buffers(void)
   define SERIAL_xxxxx_BUFFER_LENGTH move from serial_config.h to split_scomm.h
