Variable Documentation

cc110x_chanmap_433mhz_300khz

const cc110x_chanmap_t cc110x_chanmap_433mhz_300khz

extern

Channel map for 5 non-overlapping 300 kHz channels in the 433 MHz band.

This channel mapping assumes cc110x_config_433mhz_250kbps_300khz is used as configuration. (Note: The distance between channels is in fact 350 kHz instead of 300. This increased distance allows to cover the full license free range and reduce the possibility of interference of adjacent channels. Reducing the distance to 300kHz would still allow only 5 channels.)

cc110x_chanmap_433mhz_50khz

const cc110x_chanmap_t cc110x_chanmap_433mhz_50khz

extern

Channel map for 50 kHz channels with a distance of 200 kHz in the 433 MHz band.

This channel mapping assumes cc110x_config_433mhz_38kbps_50khz is used as configuration. cc110x_chanmap_433mhz_50khz_alt is an alternative channel map that does not overlap with this map. (This means devices with the alternative channel map cannot communicate with devices using this one, but also no interference is expected.)

cc110x_chanmap_433mhz_50khz_alt

const cc110x_chanmap_t cc110x_chanmap_433mhz_50khz_alt

extern

Alternative channel map for 50 kHz channels with a distance of 200 kHz in the 433 MHz band.

cc110x_chanmap_433mhz_50khz

This channel mapping assumes cc110x_config_433mhz_38kbps_50khz is used as configuration.

cc110x_chanmap_868mhz_lora

const cc110x_chanmap_t cc110x_chanmap_868mhz_lora

extern

Channel map for LoRa 868MHz channels 10 to 17 (available as 0 to 7).

This channel mapping assumes cc110x_config_868mhz_250kbps_300khz is used as configuration.

cc110x_magic_registers

const uint8_t cc110x_magic_registers[3]

extern

Magic numbers to write to the TEST2, TEST1 and TEST0 configuration registers.

Those registers are poorly documented. The data sheet refers to SmartRF Studio to obtain the correct magic numbers. Those values were identical for the 433MHz, 868MHz and 915MHz band at GFSK, 250kBaud and 127kHz deviation. Maybe by luck? So when adding a new base band or adjusting the transceiver configuration, those numbers should be checked again with the SmartRF Studio

cc110x_patable_433mhz

const cc110x_patable_t cc110x_patable_433mhz

extern

PATABLE values for the 433 MHz band.

Source: Table 39 in the data sheet on page 60.

cc110x_patable_868mhz

const cc110x_patable_t cc110x_patable_868mhz

extern

PATABLE values for the 868 MHz band.

Note

This is the default PATABLE. There is no need to upload this table unless switching between different PATABLEs is required.

cc110x_patable_915mhz

const cc110x_patable_t cc110x_patable_915mhz

extern

PATABLE values for the 915 MHz band.
