Re: Sim racing wheel

Maybe you can look into some basic electronics. If for all your digital buttons you'd use a shift register (or multiple ones daisy chained), you can have as many buttons as you want at the cost of 3 or 4 pins in total. Here's an arduino tutorial example: https://www.arduino.cc/en/Tutorial/Foundation...

Re: No one even mentioned the new Raspberry Pi Pico?

I find the looking down on the PIO a bit strange. Ok, some vendors have made similar things, some even with far better capabilities. Yet nobody in our community seems to be using them. This seems to be a very focused version that tries to solve just what the maker community would need, nothing more...

Re: Bare metal STM32 programming

Nothing stopping you, go ahead and do it. The challenges I've run into with bare metal (which I think of as CMSIS / LL / c and asm register access to hardware as opposed to using Arduino higher level functions) is name collisions, multiple definitions and hard coded interrupts in core implementatio...

Re: Bare metal STM32 programming

coding to the datasheet may sound challenging initially but it is not that hard. it allows you to migrate away from vendor libraries and develop a better understanding of the hardware -> the essence of "bare metal programming". Yeah, and the generated code just adds to that documentation ...

Re: Bare metal STM32 programming

the cubemx code generator I guess there are differing flavors of "bare metal". Picking apart the generated code and writing your own version of manually configuring all the peripherals & DMA? It really helped me when going bare metal. Interpreting the datasheet & getting every ste...

Re: Bare metal STM32 programming

Bare metal with the STM core or even without a core is also very interesting :). Once i got better acquainted with the STM32's, i really liked the cubemx code generator to generate basic code configuring the peripherals, and then continue bare metal programming with that code & the datasheet as ...

Re: Documentation on low-level peripherals programming

Sorry, don't understand. I am asking because I want to make additions to the code. It's impossible to guess :oops: for other statements concerning peripherals. There should be some manual where those commands are summarized. But where is that manual? Ok, in short, if you want to learn about that st...

Re: The following words in your search query were ignored because they are too common words: port serial com

In the old forum it was mentioned several times. The mentioner was usually advised to try advanced searches with Google. The workaround is to use an asterisk. Serial is too common but Serial* works just fine. Port is too common but Port* returns many matches. Annoyingly, since this forum has basica...
