ChibiOS Free Embedded RTOS

Yes this library

but you did a library for arduino !!!!

Giovanni you didn't answer me !!!

how do i know the exact timer frequency value of CH_CFG_ST_FREQUENCY.
i have arduino uno
please

The problem is the chVTGetSystemTimeX() not accurate on the arduini uno. i did this code

while (1)
{
start += 10;
Serial.println(chVTGetSystemTimeX()/1000);
}

i compare the values of chVTGetSystemTimeX()/1000) with my stopwatch of my phone. after 3 minutes the values of ...

Hello Mr Giovanni. i use chibios librrary for arduino and i find it powerful i tried many application on arduino uno board. but arduino board has not a real time clock. the timer of arduino it's not really accurate, so i want to use RTC DS3231. my question is how to make the function ...

Hello, i want to understand what is a tick ??
it's a counting loop ??

if i did this

for(i=0;i<2;i++)
{
do_smothign();
}

the tick here equal to 2 ??

is the tick equal to number of a while or a foor loop ?
thanks ?

Hi , i think is totally correct as result that i have look at this definition
Fixed Intervals #2
This solution does not suffer of the limitation described in the previous example however it is a bit more complex to understand&#46;

static THD_WORKING_AREA(waBlinker, 128);
static THD_FUNCTION ...

Thanks i will take a look
me i want to get a sample every 10 MS not after not befor i think chibios not really performed or me who can't to program that

I changed the program, i did a chtsleemmillis()
void mainThread() {


chThdCreateStatic(waThread1, sizeof(waThread1), NORMALPRIO+1, Thread1, NULL);
chThdCreateStatic(waThread2, sizeof(waThread2), NORMALPRIO, Thread2, NULL);


}
&#91;code&#93;
static THD_FUNCTION(Thread1, arg) {
&#91;code&#93 ...
