ChibiOS Free Embedded RTOS

os/hal/ports/STM32/LLD/I2Cv1/i2c_lld.c line 800:


is this correct, or I can't transfer 1 byte from I2C?

answering my own question and making another...

on os/hal/ports/STM32/LLD/TIMv1/st_lld.h is setting VT to use STM32 TIMER 2. STM32F103 only have 16-bits timers that is 0-65535 system ticks, converting to seconds is a little less than 8 seconds.

Is there any way to make it go higher than this?

Hi,

I'm calling runtime = ST2S(chVTGetSystemTime()) and it's resetting to zero each 8 seconds.

ch.h configuration:
CH_CFG_ST_RESOLUTION 16
CH_CFG_ST_FREQUENCY 10000
CH_CFG_ST_TIMEDELTA 2

Hi Giovanni,

I'm still have problems. I saw that you commited RTCv2 code, but I'm using RTCv1 as I'm using stm32f103... Complete make output is below.

I'm trying to use RTC on my STM32F1 but I'm having compilation error:

Hi,

How can I use stm32f1xx standard peripheral library with chibios 3?

Thanks,

Wagner

sorry to resurrect the thread.

are you successfully made ugfx works on Hy-MINI STM32V? could you share your code?

Thanks,

Wagner

Hi,

How can I wire a simple HD44780 LCD with my STM32F4Discovery board? I saw PORT_DATA and PORT_CTRL on definition file, however which pins? I want to use PB12-PB15 with 4-bits mode on my stm32f103 board. Will I need a level converter to control it using 3.3v?

Thanks,

Hi,

A simple question: What is the fastest microcontroller that chibios could run with at least GPIO, I2C, SPI, UART/USART, USB and RTC hal drivers working?

Thanks,

Wagner Sartori Junior

Success. After this explanation I declared 5 eventsource and eventlisten for each one on my threads.

Thank you very much.
