@par Example Description
This example shows how to configure the SUBGHZ peripheral to set the SUBGHZ
Radio in Tx Mode.
Starting from RADIO_MODE_STANDBY_RC mode, when the PA ramping is completed the
packet handler starts the packet transmission and SUBGHZ Radio switch in
RADIO_MODE_TX Mode.
When the last bit of the packet has been sent, status is updated to
RADIO_COMMAND_TX_DONE. The PA regulator is ramped down, the PA is switched OFF
and the SUBGHZ Radio goes back to RADIO_MODE_STANDBY_RC mode.
STM32 board's LEDs can be used to monitor the Tx Done status:
- LED2 turns ON when the Transmission process is complete (RADIO_COMMAND_TX_DONE).
- LED3 toggles when there is an error in transmission process.
@note PA regulator ramping parameter are not filled in this example.
This can be done with the command RADIO_SET_TXPARAMS.
Also the Packet is not filled. Aims of example is to switch SUBGHZ Radio
in Tx Mode and then go back to standby.
@note Care must be taken when using HAL_Delay(), this function provides accurate delay (in milliseconds)
based on variable incremented in SysTick ISR. This implies that if HAL_Delay() is called from
a peripheral ISR process, then the SysTick interrupt must have higher priority (numerically lower)
than the peripheral interrupt. Otherwise the caller ISR process will be blocked.
To change the SysTick interrupt priority you have to use HAL_NVIC_SetPriority() function.
@note The application need to ensure that the SysTick time base is always set to 1 millisecond
to have correct HAL operation.
