ChibiOS Free Embedded RTOS

Hello!

On ChibiOS/RT 20.3 (m) I'm trying to switch system timer to 64 bit mode.
If system tick frequency is 10 000 everything works. But if I change it to 1000 000 (I need 1 microsecond time precision) or even 100 000, then everything goes wrong, e.g. chThdSleep() sleeps for incorrect time (and ...

I have the same issue on STM32F103RC. Any official solution for this?

Thank you! Will try with events.

First I wanted to use NIL kernel, and 3 threads (GPIO, UART, I2C), but then how to go to STOP mode? As I understand I need to synchronize all threads before going to STOP. Also I make decision to STOP or not according to state of variables in all threads. To do ...

Hello!
I have device on STM32L051 (battery monitor) that uses I2C, UART and GPIO, now implemented using STM32 HAL.
Most of time CPU is in STOP mode, wakes up by EXTI 4 times per second, makes I2C transmission and sleeps again.
On STM32 HAL I work with I2C from EXTI handler with no problems.

Now I ...

@DeusExMachina, thanks a lot, now it works fine!
But is it possible to run HighSpeed USB on STM32F427VI? Datasheet says that it's supported: "USB 2.0 high-speed/full-speed device/host/OTG controller with dedicated DMA, on-chip full-speed PHY and ULPI". Could you point me how to do this?

Hi all!

First of all thanks a lot for the great OS and MSD driver!
I'm trying to run code of DeusExMachina from m but on ChibiOS 3.
I had to make only two changes (uncomment usbPrepareReceive/usbPrepareTransmit) and it works fine on Windows XP.
But not on Mac OS (10.9.5), dmesg doesn't show ...
