Re: idea about events

Hi Alberto,

The NULL entries in the handlers array are allowed, there is just an assertion catching the invocation of said NULL handlers.

Exactly what are you suggesting?

Re: Multipilot32 branch and ChibiOS need developer ..

There is no official I2C support yet. You could ask to various people that implemented I2C in their own way.

Re: Proposal about Threads

Good point, I think the CH_THREAD macro should also include a "noreturn" attribute, this way the compiler would detect functions that have a return path.

Re: Multipilot32 branch and ChibiOS need developer ..

I asked because you risk to hide your original message into the noise, support requests are better handled in the support forum anyway. You shouldn't expect precision nor stability from internal oscillators, I think you should measure the frequency to be sure. There is a SPI demo under testhal/stm32...

Re: Multipilot32 branch and ChibiOS need developer ..

Were the above questions meant to be in this thread or a follow-up of your latest private message? Anyway, the clock related settings are in mcuconf.h, please define what anomaly you have with the PWM, it is hard to answer such a vague question. You should expect less precision and drift from the HS...

Re: systime_t defines for TIME_IMMEDIATE and TIME_INFINITE

Hi,

The change has been implemented in the repository, it will be released in 2.3.0. It appears to have no negative effects, there were also some marginal improvements in code size and in the queues benchmark.

Re: idea about events

Hi Alberto,

I committed the proposed change under the repository, it works, I just had to rename some functions for consistency.

Proposal about Threads

Hi, I wish to open a discussion about a possible improvement in threads handling. Currently threads are normal functions and this creates some optimization problems on some architectures: ⋅ The compiler adds to the function the code for prologue and epilogue saving the used registers even ...

Re: Multipilot32 branch and ChibiOS need developer ..

Basically you want to create a C++ wrapper around the kernel and the HAL, it should not be a problem. I think you should properly present your project, expose your ideas and objective and then ask for help. I am moving this thread in the development forum, this one is for support, feel free to use t...
