STM32WL family
This ST MCU family is dual-core : based on an Arm Cortex-M4 core and an Arm Cortex-M0+ core.
Only M4 core is currently used by mbed-os applications.
Supported boards
NUCLEO_WL55JC
- Total FLASH is 256KB
- RAM: 64 KB
[tip] mbed-os export feature
mbed export -m NUCLEO_WL55JC -i uvision6
This needs to locally add a patch: https://github.com/ARMmbed/mbed-os/pull/10424/files
mbed export -m NUCLEO_WL55JC -i iar
This needs to locally add a patch: https://github.com/jeromecoutant/mbed/blob/IAR_EXPORT_SUPPORT/tools/export/iar/iar_definitions.json#L62-L64
CUSTOM boards
Check https://github.com/ARMmbed/stm32customtargets#stm32wl
LoRa
MBED-OS support
Lora radio is enabled in default STM32WL configuration
baremetal support
Baremetal is supported.
mbed_app.json:
{
"requires": ["bare-metal", "stm32wl-lora-driver"]
}
Antenna configuration
NUCLEO HW configuration is provided as the default configuration.
MBED_WEAK void set_antenna_switch(RBI_Switch_TypeDef state)
So you can overwrite it for your custom board.
GPIO debug pins
2 pins can be configured to check RX and TX activity.
Example of mbed_app.json:
{
"target_overrides": {
"NUCLEO_WL55JC": {
"stm32wl-lora-driver.debug_rx": "LED1",
"stm32wl-lora-driver.debug_tx": "LED2"
}
}
}
