Re: STM32G431CBU6 (and others) : how to make LPUART1 to work ?
This is normal it is already instantiate. Here the default pins used for Serial instance (defined to be SerialLP1): https://github.com/stm32duino/Arduino_Core_STM32/blob/f69757c5b8fd0f660387f63e308b0a9efc4fe0e6/variants/STM32G4xx/G431C(6-8-B)U_G441CBU/variant_generic.h#L158-L170 See the wiki which e...

Re: STM32G431CBU6 (and others) : how to make LPUART1 to work ?
It is not normal, the pin is configured using the value from peripheral pins. Anyway looking at your code, I don't see how you instantiate SerialLP1? If you used the generic target then LPUART1 is well initialized but for pins PAx not the one rol PBx. This would explain your issue. Simply change the...

Re: Hello. I'm trying to make a low power board.
Hello. I'm trying to make a low power board. I would appreciate it if you could give me some 'advice' or 'additional comments'. 1. Deep-sleep mode operation 2. Event occurrence: wake up 3. Save count eeprom 4. Deep-slip repeat..... Use the STM32LowPower which have several examples and read the data...

watchdog ? When it expires you can do some stuff.

Re: 'STM32WB55CE' What should I use to hold the boot?
I don't understand your question?
What do you mean by "hold the boot" ?

Hi @trimarco232
LPUART1 has some constraint around clock vs speed.

Re: Bug in SPI-library or in example sketch?
@fpiSTM just IMHO, I think we can use PA4-PA7 for the default SPI pins on c011 as the '8 pin' chip can't practically use SPI Right, physically not possible. But those file are automatically generated and have no info they shared the same pins so hard to change it. As usual, this is a default(generi...
