rfm12_set_tx_data_register_enable()

RFM12_result_t rfm12_set_tx_data_register_enable(RFM12_t *dev, RFM12_enable_t enable)

Stage the TX data register enable setting.

Parameters:

• dev – RFM12 radio instance.

• enable – Enable or disable the TX data register.

Returns:

RFM12_OK on success, or an appropriate RFM12_result_t error.

rfm12_set_rx_fifo_enable()

RFM12_result_t rfm12_set_rx_fifo_enable(RFM12_t *dev, RFM12_enable_t enable)

Stage the RX FIFO enable setting.

Parameters:

• dev – RFM12 radio instance.

• enable – Enable or disable the RX FIFO.

Returns:

RFM12_OK on success, or an appropriate RFM12_result_t error.

rfm12_set_frequency_band()

RFM12_result_t rfm12_set_frequency_band(RFM12_t *dev, RFM12_frequency_band_t band)

Stage the operating frequency band.

Parameters:

• dev – RFM12 radio instance.

• band – Frequency band to select.

Returns:

RFM12_OK on success, or an appropriate RFM12_result_t error.

rfm12_set_xtal_cap()

RFM12_result_t rfm12_set_xtal_cap(RFM12_t *dev, RFM12_xtal_cap_t cap)

Stage the crystal load capacitance setting.

Parameters:

• dev – RFM12 radio instance.

• cap – Crystal load capacitance setting.

Returns:

RFM12_OK on success, or an appropriate RFM12_result_t error.

rfm12_reset_config_setting()

RFM12_result_t rfm12_reset_config_setting(RFM12_t *dev)

Reset the staged Configuration Setting Command values to their defaults.

Parameters:

• dev – RFM12 radio instance.

Returns:

RFM12_OK on success, or an appropriate RFM12_result_t error.
