Hi everyone,I am working with the SPI in slave mode on an STM32G071 and having some trouble with the different SPI modes. I set both CPOL and CPHA to 0 during initialization: SPI_InitStruct.TransferDirection = LL_SPI_FULL_DUPLEX; SPI_InitStruct.Mode...

Hi everyone,I am working with some interrupt stuff and the interrupt needs to be fast. I need at least "-O2" optimization in gcc. However, setting the whole project to O2 is not a good solution as debugging becomes quite hard.I found two possibilitie...

Hi everyone,when I export a project from STM32CubeMX (6.1.1) to the STM32CubeIDE (1.5.1), a project with double space indent is created. However, the CubeIDE uses Tabs. How can I fix that? Who uses double space indent anyway?Thanks a lot :)

Hi everyone,I am currently working with an STM32G071. It receives data over the SPI in slave mode. The data is packet based, each currently has 4 bytes, but that will differ in the future. A single chip select sequence may contain multiple packets, b...

No, not really. Have not been using CubeMX/CubeIDE lately.

Here are the registers after initialization. Looks fine to me.Edit: Ohh sorry, that was just the initialization, before enabling it. This will also set the SPE bit in CR1, everything else stays the same.

I don't see why other functions than the one with the flag should be optimized. It did not do that in my case.But my problem is solved anyway by putting everything in the optimized function.

@Cartu38 OpenDev Including other non-optimized, non-inlined functions?

I am not trying to optimize that weak function, as I wrote my own definition, which overrides the weak one.Nevertheless, I think I figured it out myself. The "Low Level" driver is not as low as I thought it would be. The functions are not inlined and...
