Member Function Documentation
| float get_frf_MHz | ( | void | ) |
get center operating frequency
- Returns:
- operating frequency in MHz
Definition at line 243 of file sx127x.cpp.
| void hw_reset | ( | void | ) |
reset radio using pin
Definition at line 268 of file sx127x.cpp.
| void init | ( | void | ) |
initialise SX1232 class to radio
- Note:
- this is called from class instantiation, but must also be manually called after hardware reset
Definition at line 35 of file sx127x.cpp.
| uint8_t read_reg | ( | uint8_t | addr ) |
read register from radio
- Parameters:
-
addr register address
- Returns:
- the value read from the register
Definition at line 109 of file sx127x.cpp.
| void ReadBuffer | ( | uint8_t | addr, |
| uint8_t * | buffer, | ||
| uint8_t | size | ||
| ) |
read register from radio.
from an arbitrary amount of registers following the first
- Parameters:
-
addr register address buffer the read values will be placed here size how many registers to read
Definition at line 93 of file sx127x.cpp.
| void set_frf_MHz | ( | float | MHz ) |
set center operating frequency
- Parameters:
-
MHz operating frequency in MHz
Definition at line 230 of file sx127x.cpp.
| void write_reg | ( | uint8_t | addr, |
| uint8_t | data | ||
| ) |
write register to radio
- Parameters:
-
addr register address data byte to write
Definition at line 194 of file sx127x.cpp.
| void WriteBuffer | ( | uint8_t | addr, |
| uint8_t * | buffer, | ||
| uint8_t | size | ||
| ) |
write register(s) to radio, to an arbitrary amount of registers following first
- Parameters:
-
addr register address buffer byte(s) to write size count of registers to write to
Definition at line 204 of file sx127x.cpp.
Field Documentation
| RegDioMapping1_t RegDioMapping1 |
| RegDioMapping2_t RegDioMapping2 |
| RegPaConfig_t RegPaConfig |
| Callback<void()> rf_switch |
board-specific RF switch callback, called whenever operating mode is changed This function should also set RegPaConfig.bits.PaSelect to use PA_BOOST or RFO during TX. examples: PE4259-63: controlled directly by radio chip, no software function needed SKY13350-385LF: two separate control lines, requires two DigitalOut pins
