Arduino for STM32

That could be an alternative, though it doesn't really matter in my use case - I don't really care if the UART interface is stopped, or if it's just the IRQ that's disabled. Thanks for the extra info though

Ah, that makes sense - then I guess there's no way to "disable" it since it's UART that causes the interrupt and WFI doesn't distinguish between that and RTC interrupt. I'll amend my application to stop all UART interfaces prior to using sleep() and restart them afterwards. Thank you for t...

Hi, I'm using Nucleo L452RE-P, and I'm having some issues with sleep mode. I have external device (GPS receiver) connected to UART4 on pins PA0 and PA1. For some reason, when going to sleep mode using the STM32LowPower library, the STM32 will wake up whenever there's some data on the USART port. See...

Try a Google search like this spi + slave site:github.com/stm32duino here Which result of that incredibly helpful Google search is even remotely related to my question? I'm asking precisely because I couldn't find anything, neither in the repository issues nor in the library code. There is no dedic...

Not sure if this is still relevant (or which radio module is the OP trying to use), but I have a library that supports wide range of radio modules, and works on STM32 (or almost any Arduino core, for that matter): https://github.com/jgromes/RadioLib

Hi,

Is there support for slave mode in the Arduino core? I can't seem to find anything relevant in the SPI library source.

Thanks!
