ChibiOS Free Embedded RTOS

Hi, There are 2 main problems with the SDK on top of my mind: 1) Naming of types conflicting with OSAL and chibios in general, see semaphore_t but there are others. 2) Bad practice of inclusions with relative paths. This is why my preferred way is to use CMSIS files, if official ones are insufficien...

Creating board files is quite common, you may try guides on http://www.playembedded.org it is not something we can handle over the forum.

You may also try to ask on our Discord server and see if there is somebody willing to help you: https://discord.gg/s8b8v7VtrM

Hi,

Perhaps the board is different from the one used in the demo (which is old), probably there are differences and board files should be adjusted with changes.

I would verify GPIO settings related to PHY connections.

Committed with a small change, incredible how such a minor thing can impact code size so much: #if (OSAL_ST_FREQUENCY < 1000) || ((OSAL_ST_FREQUENCY % 1000) != 0) #error "LWIP requires a systick frequency that is a multiple of 1000" #endif #if (OSAL_ST_RESOLUTION >= 32) && (OSAL_ST...

Any feedback?

Hi,

Fixed in trunk and stable.

Events are meant to be the "or" mechanism.

Hi,, Just wait for events, and make a "message incoming" event, when you get the event then you fetch from the mailbox using TIME_IMMEDIATE (no wait). On the sender side send both the event and the message atomically. chSysLock() chEvtBroadcastFlagsI() chMBPostTimeoutS() chSysUnlock() Giov...

The periodic callback is just that, periodic.

The other callback is called on the deactivation front of a PWM channel, on CCR match.

Hi,

Changing period is not immediate, it is "taken" on the next ARR match, probably this is what you are experiencing. You should consider doing a custom driver if you find yourself manipulating registers directly.
