@par Example Description
How to use the different BSP drivers of external devices mounted on : B-WL5M-SUBG1 board.
At the beginning of the main program the HAL_Init() function is called to reset
all the peripherals, initialize the Flash interface and the systick.
Then the SystemClock_Config() function is used to configure the system clock
(SYSCLK) to run at 64 MHz.
This example shows how to use the different functionalities of components
available on the board by switching between all tests using User Button1 push-button.
** Push the User B1 push-button to start first Test.
### LED ###
This example shows how to use turn on/off and toggle the LEDs.
### FLASH ###
This example shows how to Read/Write to the SPI external flash.
### TEMPERATURE ###
This example shows how to use the sensors to get temperature values. Both,
STTS22H and LPS22HB sensors are used.
### GYROSCOPE ###
This example shows how to use the ISM330DHCX sensor to get gyroscope values.
### ACCELERO ###
This example shows how to use the ISM330DHCX sensor to get accelerometer values.
### RADIO ###
This example provides of how to use RADIO in Rx or Tx (HP/LP) modes
Depending on IDE, to watch content of Terminal I/O note that
- When resorting to EWARM IAR IDE:
* Command Code is displayed on debugger as follows: View --> Terminal I/O
- When resorting to MDK-ARM KEIL IDE:
* Command Code is displayed on debugger as follows: View --> Serial Viewer --> Debug (printf) Viewer
- When resorting to STM32CubeIDE:
* Command Code is displayed on debugger as follows: Window--> Show View--> Console.
In Debug configuration:
- Window\Debugger, select the Debug probe: ST-LINK(OpenOCD)
- Window\Startup, Depending on IDE, to watch content of Terminal I/O note that
Results can be displayed on PC (through HyperTerminal or TeraTerm) by Virtual Com Port
in enabling USE_VCP_CONNECTION compilation switch and with the proper configuration described
in paragraph "Hardware and Software environment.
@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.

@par Hardware and Software environment
- This example runs on STM32WL5Mxx devices.
- This example has been tested with STMicroelectronics B-WL5M-SUBG1 boards.
- B-WL5M-SUBG1 Set-up
Connect ST-Link cable to the PC USB port to display data on the HyperTerminal.
A virtual COM port will then appear in the HyperTerminal.
- Hyperterminal configuration:
- Data Length = 8 Bits
- Stop Bit: One Stop Bit
- Parity: None
- BaudRate: 115200 bauds
- Flow Control: None
@par How to use it ?
In order to make the program work, you must do the following :
- Open your preferred toolchain
- Rebuild all files and load your image into target memory
- Run the example
