ChibiOS Free Embedded RTOS

I think this is an excellent development. I know when I looked at the licensing options a while ago, the only concern that I had was the need to tweak something in the HAL and what impact that might have had on what version I could run. This latest change completely removes any concern on that ...

Please read all the related documentation. I don't know how this can be «hazy»?

It's the ADCCLK clock.

The STM32_ADC_ADCPRE macro in your mcuconf.h defines the prescaler for that clock.


You'll also want to make sure you look very closely at the diagram in the relevant reference manual ...

I also fixed the expression in the CRC checking offload but I am not sure how to test that, forgot how to patch lwIP about that.

See the "checksum options" section in lwipopts.h. There are a bunch of "CHECKSUM_..." defines that tell lwIP not to verify checksums on reception and generate them on ...

Thanks, this is just the sort of pointer I was looking for. I didn't know that the serial driver had an event source, I'll investigate that further.

I'm wondering if there would be use for a common capability through the I/O channel, Sequential Streams or I/O Queues abstraction to be able to have ...

I've been hacking along on an application, and I'm trying to reduce the number of threads to cut down on the per-thread stack RAM use. My application has a somewhat complex state machine at the core. At present, I have multiple tasks using the state machine protected with a mutex to ensure one trip ...

I wonder if that's a 24MHz 3rd-overtone crystal, oscillating at it's base frequency of 8 MHz? I think that the capacitance in the circuit is somewhat critical based on what I remembered reading some app notes about this sort of thing months ago. I think it's fairly unusual to have a socket in this ...

Then you can just make serial ports accessible through the C library by implementing the whole syscalls.c, much easier than creating a whole Posix wrapper.
That leaves the actual paths to the devices...

4\/3!!

I'm not really at all interested in more complete POSIX emulation in ChibiOS; if I ...

Should Giovanni spend his time learning a new revision control system, or writing code? It seems that if git has an interface to a subversion repository, then all the rest ought to be able to git to their heart's content already.

Besides, everyone knows that hg/Mercurial and emacs are clearly the ...

I think this also applies to the I2C peripheral in the STM32L15x family, too. I recall having a similar problem using the STM32LDISCOVERY board.
