ChibiOS Free Embedded RTOS

If you look in commercial OS At the risk of stating the obvious... ChibiOS is open source, free, and sent into the world as a gift. The driving force is generosity, not commerce. Wouldn't it be more effective to write examples, and post them here or send them to Giovanni for review and discussion? ...

Ok, it compiles. The added files/dirs so far are: demos/LPC8xx/ os/common/ports/ARMCMx/compilers/GCC/ld/LPC812.ld os/common/ports/ARMCMx/devices/LPC8xx/ os/ext/CMSIS/NXP/ os/hal/ports/LPC/LPC8xx/ os/rt/ports/ARMCMx/compilers/GCC/mk/port_lpc8xx.mk Next step will be to debug this stuff. Some clock or ...

Never mind. Inserted volatile uint32_t for now.

Ok, thanks for that reference - hadn't seen it. Making good progress now.

Another Q: what is the new name for IOREG32?

Hello Giovanni, While I understand and respect your position, it would actually be a lot easier to handle different platforms if you were to support at least one of each type. The ST32F µC's are probably a lot easier to port across different variations, than starting on a new one. Having said that, ...

I've been using ChibiOS for a number of projetcs, using various chips and boards from STM and LPC, mostly. So far, getting thigs going for STM has been very easy, and for LPC it was fairly easy as well to adapt existing demos and makefiles. For as-yet unsupported LPC chips, I managed to make it work...

Just to try out nil, since my code won't be needing much more for now, I tried switching from RT to NIL. One snag is that chprintf.h has a hard dependency on "ch.h". Given that the names of calls and macro's are kept at "chBlah...", might it be a better idea to also keep Nil's he...

Unrelated, but probably a typo in a few files:



Should be 330 (or completely removed even), I think - at least on most Nucleo and Discovery boards.
Not that it makes a difference, only STM32F4xx uses it, and only wiith 270..360 as range check.

FWIW, I'm not succeeding yet in making the on-board LED blink. Tried both GPIOA 5 and GPIOB 13 (which it is on some Nucleo boards). I disabled the serial port code in main.c to try and narrow down the problem. Can't seem to make the LED do anything, even with a manual palSetPadMode + palTogglePad. I...

Woohoo - the demo and my test project are now compiling! Will test further soon, thank you!
